PREFACE This work is intended to give brief and practical farming suggestions that will be helpful in the growing and using of forage crops. Special atten- tion has been given to soiling crops and to rota- tions, in order to suggest a continuous supply of forage throughout the growing season, a subject of increasing importance to dairy farmers in the vicinity of large cities. These suggestions for both crops and rotations have been found to be satisfactory in practice, but the work must be carefully planned if it is to prove successful. The systems of forage-crop rotations here outlined are intensive, and to secure the full benefits from their adoption the cropping must be accompanied by liberal use of manures and fertil- izers and by extra good tillage. The suggested improvements in the systems of rotation for general farm practice, where grain crops are the chief object, have also been found to be practicable for many conditions, although they (v) vi PREFACE are yet largely experimental, and in use mainly on small farms; their adoption, however, would result both in increasing the yield and quality of forage from a given area, and, if judiciously carried out, result in a better preparation of the land for grain crops. No attempt has been made to discuss all crops that may be used for forage, although those which have been found of service under special condi- tions have been included, as, for example, the millets, kafirs and a few of the less well-known grasses. The data in reference to these, however, have been drawn largely from the experience of others. Special attention has been given to the legumes, as their use is of the utmost value in any system of forage cropping, and many of those recently introduced.possess such habits as to per- mit their use without interfering with regular grain- crop rotations.

The yield was sixteen and two-thirds tons of green forage per acre, which contained 7,637 pounds of dry matter, or practically twice as much dry matter as was con- tained in the yield of either red or white kafir corn. Its composition was such as to furnish nearly 700 pounds of protein per acre, or more than any other of the plants generally grown, and again more than twice as much as the kafir corn. From the standpoint of yield of dry matter and of total nutrients, the Broom-corn millet compared very favorably with the varieties of maize usually grown for forage, yet because of lack of palata- bility it could not be used for the purpose. It possesses promising characteristics, in particular its power of gathering plant-food; and further experiments may show it to be a valuable plant for silage in regions where corn does not develop. ‘yavtd oq} Jo yIqvy AYsnq Jo Surqouvaq aq} eJ0N “oUISOaT, ‘cy “S1q Lt ahes Pree Sees ep 5 In ANG Ne AVIAN 94 FORAGE CROPS TEOSINTE (Fig. 15) This plant is similar in general habit to millet, but differs in its tendency to stool. It belongs to a wholly different species (Huchlena, or Reana, luxu- rians) from the other crops discussed in this chap- ter, but it 1s so much like millet in its cultural requirements and in its uses that it may be dis- cussed with them. By some it is suggested as the original of Indian corn. A single plant of teosinte will branch and make a very large number of dif- ferent plants. So far as plant-food is concerned, teosinte makes the same requirements as the other very rapid-growing summer plants. Teosinte should be planted in rows about three feet apart, and tilled. Three pounds of seed per aere is suffi- cient. It is adapted only to the far South. Yields as high as twenty-four tons per acre have been secured, although, because of the low content of dry matter, the yield of actual nutriment is very much less than from ten tons of corn.

All these various sorghums are considered to be forms of one vari- able species, Sorghum vulgare or Andropogon Sor- ghum, native to the Old World. The non-saccharine fodder sorghums include all the douras (spelled also dhoura and durra), Egypt- tian corn, milo maize, kafir corn. There is no one name that is now used to designate this group, but kafir corn is now best known and is thought by some to be destined to become the popular class name, although doura is the oldest and most attractive name. The kafir corns bear’ a contracted dense panicle or head, in distinction from the long, wisp-like heads of the broom-corn; some of the sweet sorghums bear drooping heads, but they are chiefly distinguished by their sweet juice. Of the kafir corns there are two groups, —kafir corn proper, with erect, rather long heads (95) = NX Fig. 16. Black-hulled White kafir Corn. KAFIR CORN 97 and not flattened seeds; and douras proper, with hanging or recurved short and compact heads and flattened seeds. Jerusalem corn and Yellow milo maize are douras. White milo maize belongs to the kafir group. Some of the forms are distin- guished in Figs. 16 to 21 (all figures in this chap- ter except Nos. 19, 22 and 23 are from Kansas Experiment Station photographs). The grain in the heads of the kafir corns is useful, as well as the fodder, but it is not the purpose of this book to discuss the grain production. Forms of doura and kafir corn have been known in this country for many years, but it is only recently that they have come to have real agricultural importance, due largely to their adaptation to the hot and dry regions of the western country. Kafir corn is a valuable plant for dry hot countries, and also for the East, since it is a rapid grower, producing a large number of wide, luxu- riant leaves that are extremely palatable. It serves an excellent purpose for seeding with such legumi- nous crops as cowpeas, serving as a support for the pea, aiding thereby to produce a much larger yield of food of higher quality than if either were seeded alone. Plants of the same nature are Jerusalem corn, Rural Branching doura, Yellow Branching doura or milo maize, and Evergreen broom-corn. The seed of all these plants is similar to that of sorghum and may be similarly treated. It may be G 98 FORAGE CROPS Fig. 17. Typical head of Black— Hulled White kafir Corn. sown broadeast at the rate of four to five pounds per. acre, or planted in rows and cultivated as for Indian corn; the latter is the better method when large yields are desired. Kafir corn is similar to sweet sorghum in habit of growth. It grows from five to seven feet high, with a stalk much like corn. The leaves are heavy and somewhat stiffer than those of corn. They run from one to two and one-half feet long. The grain appears on a head that reaches a length of twelve to sixteen inches; but these heads are compact, and do not spread out, as in the sweet sorghums; on the mature head there is no stem in sight, except at the base, the grain only being visible. The different kinds of KAFIR CORN 99 this class of plants should be seeded the latter part of May or first of June. They will make a crop ready for harvesting in two to two and one- half months. For green forage they should be cut as they are just coming in head, in order to secure the best yield of succulent and nutri- tious food. They harden rapidly after seed be- gins to form. In the western states, these plants are largely grown for the grain, the ground meal making an excellent substitute for corn meal. While the dried fodder or hay makes a good for- age, it possesses no advantages in humid climates over crops that are better known and more easily handled, as, for example, corn. In regions of little rainfall, these crops are of unusual value.

The crops were cut when in best stage for soiling, and, with the exception of the Evergreen broom-corn, were palatable and readily eaten by regularly soiled dairy cows. It will be observed at once that, with the exception of the Evergreen broom-corn, all the crops showed a much lower content of dry matter than field corn.

It will be ob- served that the Yellow Branching doura gave the largest yield of total fodder, and the Red kafir the lowest; the Evergreen broom-corn showed the largest yield of dry matter, and the White kafir the lowest; the Early Leaming corn showed the next largest yield of dry matter, and a much lower con- tent of crude fiber than the Evergreen broom-corn. The yield of dry matter, excluding fiber, was 5,690 pounds for the Leaming corn, and 4,779 for the Evergreen broom-corn, a gain for the Leaming of KAFIR CORN 911 pounds, or 19 per cent. On the dry matter basis, therefore, the only variety that at all com- pared with maize was the Ever- green broom-corn, which is very inferior in palatability and diges- tibility. The kafir corns are not comparable with corn on the basis ef yield of nutrients, and are not to be recommended except as sub- stitutes for corn in climates too dry for the latter. One point should not be lost sight of with all these quick-grow-. ing summer crops,—they are relatively exhaustive of the avail-. able plant-food in the surface soil. For example, a crop of eight tons of Barnyard millet, which fairly represents this group of forage crops, will remove from an acre in fifty to seventy-five days in round numbers 50 pounds of nitrogen, 26 pounds of phosphorie acid, and 104 pounds of potash. The same yield of maize will re- move from an acre in eighty to. one hundred days only 101 Fig. 18. Typical head of Red kafir corn 102 FORAGE CROPS Fig. 19. Yellow milo maize, one of the doura yroup. 45 pounds of nitrogen, 20 pounds of phosphorie acid, and 50 pounds of potash. This is 10 per cent more nitrogen, 30 per cent more phosphoric acid and over 100 per cent more potash removed by the special crops than by the corn. The land, therefore, is more rapidly and completely de- pleted of its available plant-food by these summer-grown plants; and this accounts for the fact that they cannot be successfully grown on poor soils, and that subsequent crops, that have apparently less ability to ap- propriate plant-food, cannot be successfully grown without liberal manuring or fertilizing. These characteristics should be always taken into con- sideration when substituting this class of crops for corn in forage crop rotations. KAFIR CORN FOR DRY REGIONS It has been said that the non-saccharine sorghums are KAFIR CORN IN KANSAS 103 especially adaptable to semi-arid and hot regions. It may be well, therefore, to present a brief account of these plants to show their value for the interior western country. The results of experiments at the Kansas Ex- periment Station are probably applicable for those regions in which the crop is a prominent one, and a brief résumé and adaptation of the report of Professor J. G. Haney,! of that Station, comprises the remainder of this account of kafir corn. Varieties for dry regions There are many varieties of the non-saccharine sorghums, but only three that have come under the name of kafir corn. The name kafir comes from the name of a tribe of natives of South Africa, whose country is known by the same name of kafir. Kafir corn is sometimes known as Afri- can millet. The three varieties which have received most attention are, in the order they were intro- duced: (1) The White, (2) the Red, and (8) the Black-hulled White. The last may be easily dis- tinguished from the first by noticing that the chaff or hull which partly envelops the grain is black, while in the first the chaff or hull is nearly the color of the grain; hence, the first is called White and the last Black-hulled White. In the Red, the 1Forage and Fodders, Kansas State Board of Agriculture, Report for 1900, 104 FORAGE CROPS color develops as the seed matures, and at maturity is very nearly a brick-red. The kafirs should not be confounded with their sisters—Jerusalem corn, milo maize or rice-corn. All the varieties of the non-saccharine sorghums that will mature in Kansas have been tested side by side. For the extreme northwestern counties of Kansas, observation shows that kafir corn is not so well adapted as Jerusalem corn or rice-corn. The altitude being high, the short seasons and cool nights seem to affect the kafir corns so that they often will not mature seed. Although they always make fodder, and sometimes a good crop of seed, they are not so reliable as the others. The White kafir corn with some is the favorite for fod- der, and all varieties have their admirers, but at the Kansas Station all have been abandoned for the Black-hulled White. It has proved the heaviest yielder in both grain and fodder, and if there 1s any difference between it and the Red for resisting dry weather, it is in favor of the Black-hulled White. There is a greater difference between the Red and the White in these respects than between the Red and the Black-hulled White. For the first seven years the Red was grown. The Black-hulled White was then tested, and from 1896 to 1898 the two varieties were grown side by side, the Red giving an average yearly yield of thirty-seven bushels per acre, and the Black-hulled Typical head of Dwarf milo maize, a form or strain Fig. 20. of the Yellow milo maize, 106 FORAGE ChOPS White forty-three bushels per acre. The yield of grain per acre by years is as follows: Red Black-hulled White bushels bushels 1896s « e aOR te ela eae a 41 48 OT eign ce a See ia gah igh RE Ose ona 41 48 OOS eres ite sey Ney See GPa netra: Wen A 28 33 MOtaleieon. gia el ara 110 129 Averages ....... ‘ 37 43 In western Kansas, many farmers raise the Red, thinking it a little hardier and earlier. In central Kansas some feeders raise both the Red and the Black-hulled White, and feed alternately, the stock seeming to relish the change. Records show the Red to be from a week to ten days earlier than the Black-hulled White, but this difference is of little importance in central Kansas. Kafir corn planted the middle of May is ripe the middle of September. Soils and conditions of growth Kafir corn will grow very nearly within the same climatic limits as Indian corn, and under ordinary conditions will produce a crop when corn does. However, it seems to require a slightly warmer climate for its best development. When its growth is being held back by unfavorable con- ditions, frost comes before it is ripe. It responds as readily to good soil and favorable conditions as KAFIR CORN IN DRY R#GIONS 107 any other crop; yet, on poor land, and under conditions that would not produce a crop of corn at all, kafir corn does surprisingly well. It is a very strong feeder, having an extended root system which reaches deep and wide for necessary moisture. : Dry-weather-resisting qualities Kafir corn is the greatest dry-weather-resisting crop that can be grown in Kansas. It grows and develops in proportion to the moisture which it can collect by its extended root system, and, when unable to continue growing, it stops and lies dor- mant, so to speak, until the moisture does come, and then continues its growth. If the rains are sufficient, and the frost does not come too soon, it will make a good crop, although it has stood com- paratively dried up for six weeks. Corn to some extent will renew its growth after a moderately dry period, but not in comparison with kafir corn. Preparation of land in dry regions Listing is not generally satisfactory. Being slow to start, the plant needs to be up where it gets all the warmth possible, which is not the case in a lister furrow. And, after listing, if a dashing rain comes and runs the soil down in the furrows before the plants are well started, there will not be a good 108 FORAGE CROPS stand. It does not have sufficient foree to push through soil that has washed down and settled over it. Surface-planted land may be affected by dashing rains, but it is not likely to be. The washing and settling of the soil by rain, of course, depends a great deal on the character of the soil, Wiest Fig. 21.

KAFIR CORN IN DRY REGIONS 109 as some soils wash and pack more readily than others. Listing, however, in the western and drier sections is the favorite method of planting, as it takes less work, encourages the roots to go deeper into the soil, thus better resisting drought. The rows should be about three feet apart, and the seed dropped four to eight inches apart in the row for the western part of the state. For surface planting, fall plowing is very gen- erally favored. The disadvantages of fall plowing are: The blowing of the loose soil, and the weeds, which thrive best on fall plowing. Otherwise, a good disking or fall plowing furnishes the ideal seed-bed. Spring plowing should not be done until time to plant. The plowing should not be deeper than is necessary to turn the ground well and cover trash. A very essential feature in the preparation of the seed-bed is to compact the soil as soon as plowed, so as to hold the moisture near the surface. The plowed soil should not be left as smooth on the surface as when a roller is used, nor as fine as an ordinary harrow would leave it. The day the land is plowed, it should be disked, harrowed, then rolled, and harrowed again, to make the surface fine and compact. The press drill, with all the drills left on, is the best implement for planting, if done the same day that the land is plowed. 110 FORAGE CROPS Distance apart and seed required For hay or fodder, it should be planted close, and the greatest yield may be secured by broad- casting or putting in with a wheat drill, set to sow one and one-half bushels of seed per acre. For producing grain it should be planted in rows with a view to cultivating. For the western and drier country, rows should be three to three and one-half feet apart, and the seed from four to eight inches apart in the rows, while for the eastern areas of greater rainfall, better results are obtained by put- ting the rows two and one-half to three feet apart, and the seed from two to four inches apart in the row. For western planting six to seven pounds per acre will be all the seed required, while for eastern planting ten to twelve pounds per acre will give the best results for grain. Any drill or drill planters may be used it adapted to such small seeds, and to drop them the proper distance apart. Perhaps the most prac- tical is the ordinary grain drill, tacking a piece of pasteboard over all the holes except those which will plant the rows at the proper distance. Time to plant Kafir corn, having a rather low vitality, and growing slowly after starting, should not be *(4ySta oq} 03) Vanop Suryouvrg [einy pue (4Jo] O44 OJ) OZLEMU OTLUL MO[JOA ‘ZS “SLA +(4q311 oq} Uo) u109 AyeH $(9J0] O49 WO) JOT “Es “Slag KAFIR CORN 1N DRY REGIONS 113 planted until after the ground is well warmed, and there is no danger of frost. It comes properly just after corn planting, there being no hurry until the last week in May, but it should be in early enough to have plenty of time to ripen before frost, taking into consideration the fact that the plant makes but little growth in very dry periods. Seeding in dry regions As in all crops, it is essential that good seed be planted as a first requisite to a high yield and a good stand. Kafir corn heats very often, when stored in quantity in bins, or when sacked and in a dry place, especially if the sack is closely woven and there is some dust in the seed. It is always risky to trust seed that has been stored in any quantity in a close bin, as its germinating power | may be impaired. Hence, seed that is not fresh, or new, should not be trusted. It may even sprout in a germinating pan, and yet have a low vitality that would give a poor stand. The best heads from the best plant in the field, under ordinary conditions, should furnish the seed for the next year. If the seed is left to cure on the stalk in the shock, the selection may be made at any time before thrashing; if left on the head and stored away in thin tiers in a dry place, until needed for planting, good seed is insured, H 114 FORAGE CROPS Cultivation of kafir corn fhe eultivation should be the same as for corn, frequent and shallow, rather than deep and infre- quent. Harrowing early is almost indispensable in order to keep down weeds. After the plants are three inches high, they will stand almost any amount of harrowing and this may be continued until eight inches high. Fig. 24 Roots of katir corn, sixty days after planting. KAFIR CORN IN DRY REGIONS 115 Harvesting time for grain Kafir corn remains green until frost, and the seed does not shatter; so, if grain is the only con- sideration, there is no great hurry to harvest; it can stand until after frost and the stalk is dry. But, generally, the fodder is a consideration, as well as the grain, and then the problem is to cut when the best results from both may be obtained. Fig. 25. Roots of sorghum, sixty days atter planting. 116 FORAGE CROPS The longer the fodder stands, the harder and less palatable it becomes, while if cut too early the best yield of grain is not secured. After the grain is hardened so that it is difficult to mash between the thumb and finger, and there is apparently little-moisture in the seed, there will be very little shrinkage in the grain. This would perhaps be called “just past the hard-dough stage.” If cut earlier, the fodder will be better feed, but there will be a considerable shrinkage in the grain. Methods of harvesting One thing that has kept this crop from being more generally raised is the problem of harvesting. There are a number of methods, and they all have their merits. If the fodder is desired for feed, it is perhaps best to cut stalk and all, and leave it in the shock until dry. The best machine for accom- plishing this is the corn-binder, which leaves it in bundles of convenient size for handling, and the fodder is held together. In the western and drier regions, if not planted too thick, it does not grow so high that it cannot be cut with an ordi- nary grain harvester, and this method is quite extensively used. The ordinary corn sled may also be used for cutting, and if the seed is to be fed with the fodder, this is perhaps the most in- expensive, KAFIR CORN IN DRY REGIONS 117 In threshing, the whole stalk can be run through a common grain-separator, but this is hard on the machine, and as a general thing a thrasher will not do such work a second season. The fodder is cut and broken up, and, while some hold that this is an advantage, it soon loses its flavor, and, if not thoroughly dry, will heat and spoil after stacking. Stock will eat the thrashed, broken-up fodder while it is fresh better than when whole, but in a short time it gets stale. When the kafir is bound, the grain may be removed by thrusting the heads into the cylinder of a thrashing-machine for an instant, and throw- ing the fodder off on a wagon. When it is desired to take the fodder at once from the field, this would perhaps prove the most economical method. When planted thick or sown broadeast for hay or fodder alone, it should be eut when most of the seeds or heads are in the milk or early-dough stage. At this time more nourishment will be in the stalks and leaves; besides, not being so hard as when fully matured, it is more easily digested, stock eat it more readily, and there is less waste. A great many make the mistake of cutting too early, often with the view of getting a second ercp. The nourishment in any feed is.conditioned on the process of maturing; the compounds must be elaborated and fixed in the tissue before they are food. Cutting any feed before the blooming period 118 FORAGE CROPS may give a great bulk of material, but it is watery; it dries out, the fodder shrinks, and an animal cannot eat enough of it to satisfy the appe- tite. One crop is all that ought to be expected from one seeding, and more profit is made by a single crop than two, if labor is counted as worth anything. The feed secured by two cuttings may go a little farther than the feed secured by the Fig. 26. Matured kafir corn roots. KAFIR CORN IN DRY REGIONS 119 single cutting, but it will not go nearly twice as far. Cutting and curing for hay As before stated, kafir corn should be cut when the seed is in the milk or early-dough stage. The eutting may be done with a grain-binder, and shocked to cure as small grain. This leaves it ina very fine condition to handle when feeding, but is Fig. 27. Matured sorghum roots 120 FORAGE CROPS rather hard on a machine and somewhat expensive. The ordinary method is to cut with a mower, and the crop should be left to cure well before raking. Ordinarily, in the middle and western part of Kansas, after being cut and raked, it is put into large shocks or small ricks containing from a ton to three tons each. This is done with a hay-gath- erer, “buck-rake” or “go-devil,” and saves a great deal of handling. It keeps in excellent condition when treated this way, and can be hauled when needed. Under ordinary conditions kafir corn will be ready to harvest for hay in about 105 days after planting, and this should be before frost, as freez- ing while green is detrimental; besides, the hay will not cure as well in cool weather, and it is essential that it be as perfectly cured as possible. Yield of grain in kafir corn The yield of grain will range from twenty to ninety bushels per acre, with an average of about forty-five bushels in eastern Kansas; in the western and drier parts of Kansas it is smaller, though there the difference in yield between kafir corn and Indian corn is proportionately greater than in the eastern parts. At. the Kansas Sta- tion the average yield of kafir corn for eleven years was forty-six bushels per acre, while for Indian corn it was thirty-four and five-tenths KAFIR CORN IN DRY REGIONS 121 bushels. The yield of hay will also vary widely from one-half to three tons per acre, according to climate, soil and season. Storing the grain Great care must be taken in storing the seed in close bins, in quantity, especially if not well cleaned. It settles together so closely that air seems to be excluded and heating results. In the spring during damp spells, it is often necessary to shovel the seed from one bin to another, or from one side of the bin to the other, to keep it from spoiling. Slightly-heating does not injure it for feeding purposes, but destroys its germinating power. There is often damage to the heads when stored in corn-cribs, but it is not so probable as in the thrashed grain. CHAPTER VII THE SWEET SORGHUMS THE sweet or saccharine sorghums are used both for the making of syrup and for forage. They are more corn-like in appearance than the kafirs because the panicle is more like a corn tassel in form. This panicle or head is usually loose and open, although it may be more or less dense when its grain is ripe. The grain is borne in the panicle or tassel, not in ears. The general directions for the growing of the kafir corns (Chapter VI) apply very well to the sorghums. The varieties of sorghum well adapted for soiling are Early Amber and Early Orange. The Early Orange produces a larger and heavier growth, and is a little later than the Early Amber, and is thus more suitablo for sections in which the seasons are long. The soils best adapted for sor- ghums are deep, moist loams, or those most favor- able for maize, although the crop may be grown successfully on light lands if they are well ferti- lized. Sorghum seems to be capable of withstanding drier conditions than corn, and thus its use is increasing where droughty conditions are liable to occur. (122) SWEET SORGHUM 123 Preparation of svil and seeding The preparation of soil for sorghum should be similar to that recommended for corn,—a deep, well-cultivated seed-bed, but for sorghum the crop should preferably be immediately preceded by a cultivated crop, in order to free the land of weeds. The plants germinate readily, but make a very thin and slow early growth, thus rendering it difficult to keep clear of weeds. When the crop is intended primarily for forage, it may be seeded either thickly in rows, or broad- easted. If seeded in rows, from ten to twelve pounds of seed per acre are sufficient. If broad- . casted, twenty to twenty-five pounds will be required. The crop should not be planted until’ the soil is thoroughly warmed, and the weather likely to be hot, as the plant does not thrive in cold, moist weather. Broadcast seeding is not recommended except on clean lands, as the weeds are likely to start vigorous growth and seriously reduce the yield of the sorghum. To grow maximum crops the land should be well manured or fertilized; inasmuch as it is a cultivated plant, which roots more deeply than the millets, the nitrogen requirements are not so ex- acting. However, the soil should be abundantly supplied with available phosphoric acid and pot- ash. A good dressing of manure of six to eight 4 ‘UvMs[oD (F) fesuvig sesuvy (¢g) {yavaq Hovlg (z) fdequry Ajreq (1) :o18 SOTJOLIVA 949 “GYSII 07 4JaT WoOIT SUIpBay ‘WINGTIOs yaaMs Jo saarqVa qusieyip Jo speey [eorddéy, ‘gg “St 4, nts’ Cat cau SWEET SORGHUM 125 tons, well cultivated into the soil, should be fol. lowed by an application of 200 to 300 pounds per acre of a commercial fertilizer containing NERO POD sos ke ee a SS we 3 per cent Phosphoric acid (available) ...... 8 per cent Potash. 2 i 5 ee 4 Sa de oe ew S 5 per cent Yield and value Sorghum is frequently allowed to grow to a height of five to six feet, and then cut and permitted to make a second crop. By this method, the largest yields of succulent forage are obtained, ranging from eight to thirty tons per acre, although the latter figures are exceptional. An average of ten tons may be regarded as good, and this should be secured under medium conditions of soil and in usual seasons. Sorghum is a sugar-producing plant. It is very palatable, and is readily eaten by all farm stock. In their immature state, however, the plants do not contain a high content of dry matter, being similar in this respect to millet, although they are more palatable when mature. The quantity fed may range from fifty to seventy- five pounds per day, in two feeds. The sugar forms very rapidly after the heads begin to appear, and this formation of sugar, while accompanied by a considerable increase in crude fiber as the plants 126 FORAGE CROPS approach maturity, makes the forage sweet and encourages the animals to consume the coarser materials more readily than is the case with the millets or kafir corn, or even maize (except the sweet varieties). Sorghum is not well suited for hay, although it can be used for the purpose if cut early. It can be used for silage with advantage. It can also be harvested and allowed to dry, and the seed threshed; the dry stalks are then practically as useful as corn-stalks, and the seed can be ground into a feed which is similar to corn-meal in its composition and feeding value.

Varieties for Kansas Of the large number of varieties, those found to be most desirable in the West are: Folger, Fig. 29. Field of Orange sorghum in Kansas. early; Coleman, medium; Collier, late. The Early Amber and Early Orange are very valuable for the East. The main points to consider in choosing varieties are (1) time of maturity, (2) proportion of foliage to stem, (3) sweetness, Sorghum at good stage of maturity for soiling. Fig. 30. SWEET SORGHUM 129 Preparation of land There is a prevailing opinion with farmers that sorghum does not require the care in the prepara- tion of soil and its cultivation that is demanded for corn. This may be true in part, but the plant responds readily and profitably to good treatment, and it usually pays well thoroughly to prepare the soil before planting. This good preparation not only destroys weed seeds, but increases the water- storage capacity of the soil, insures quick germi- nation and rapid early growth. Seeding in Kansas Sorghum may be seeded any time that is suit- able for seeding corn; if planted from the first to the twentieth of May, it will ordinarily catch enough of the spring rains to secure a fine growth before the hot and usually dry weather of the western states begins. When grown for the mature plant, it should be planted in rows, about three feet apart, and the seed distributed evenly in the row, at the rate of one peck to one-half bushel per acre. After plant- ing, the land should be harrowed to keep the sur- face loose, and as soon as the plant is well started, the ground should be frequently cultivated until the plant is thoroughly established. While the I 130 FORAGE CROPS young plant is slower than corn to start, and thus difficult to keep clean, especially in moist warm weather, it grows quite as rapidly, if not more so, when well established, and later cultivation is not so important. Sorghum is usually grown for the making of hay, and therefore a much thicker stand is wanted and broadcast seeding is practiced. The best method of seeding is to use a press drill, sowing from one and one-half to two bushels per acre, sufficient to have the stand thick, like wheat or rye, if the best hay is to be obtained. Harvesting and curing sorghum The crop may be cut for forage when two or three feet high, in which case it is possible to get a second crop quite as large as the first. For hay, however, it is better to let the plant reach a more mature stage, so the seeds begin to harden and the plants to turn yellow. At this stage, it will make more and better feed than if cut earlier or later. If the stalks are not more than six feet tall, the method commonly used for hay is to cut with a mower, allow it to wilt, and then, with self- dumping rakes, carry enough together to make small stacks of 800 to 1,200 pounds. By this method, experienced growers find that the least labor is involved, and that the product keeps green SWEET SORGHUM 131 and sweet. The time of cutting should be the same if planted thinner, except that it should be cut and put in shocks, as in the curing of corn-fodder. For many sections, sorghum is one of the most useful crops of the farm; it is easily grown, resists drought, and makes a large quantity of forage that is relished by all farm animals. In the South it is grown largely for making syrup. It was formerly used somewhat for this purpose, even as far north as Michigan, before the days of cheap sugar. As a special crop, sorghum cannot be recom- mended too highly. When properly grown it produces from four to six tons of dry feed per acre. CHAPTER VIII MAIZE OR INDIAN CORN THERE is no one crop that is equal to corn for forage purposes. If it could be so grown as to supply green forage from May 1 to November 1, there would be no good reason for the introduction in soiling systems of any other plant of the same group. The reasons for this broad statement are, (1) that corn is adapted to a wide range of soils, and thus can be successfully grown for forage practically everywhere in the United States; (2) it makes the largest yield of digestible dry matter per acre, other things being equal, of any crop that is now grown; (3) in its immature state it is very palatable and is eaten practically clean by all classes of farm stock up to the time that the grain begins to harden; (4) it is one of the least expensive crops to grow, largely because of the cheapness of seed; (5) it can be completely utilized, either as a grain crop or winter forage crop, if not needed as green forage to supple- ment pastures, or if the yields are larger than needed for soiling; (6) it is the only wholly satisfactory silage crop; (7) it is a tilled crop, and its use may improve the land. (132) MAIZE FOR SOILING 133 CORN FOR GREEN FORAGE OR SOILING The choice of variety and method of growing should be modified to meet the special require- ments of soiling. It should be remembered that the purpose in the growing of soiling crops is not nutriment alone, but rather a combination of suc- culence, palatability and nutrients. Those varieties that make most rapid growth and develop early are, all things considered, more desirable than those that give a larger proportion of stalk and ear to leaf, because the shorter period of growth enables the gathering of two crops of green forage in one season as far north as New Jersey. The Rural Thoroughbred White Flint represents a type that gives excellent satisfaction in the Middle States, as it possesses in marked degree the char- acteristics already recommended. The branching habit is also well developed; from three to four stalks will sucker from the main stem, thus gradu- ally thickening and maintaining the succulent char- acter of the forage for a longer period than those not possessing this habit. In New Jersey and points south, this variety, if planted by May 1, will be ready for harvesting by the middle of July; and if another crop is planted at this time, it will reach a good stage of development previous to kill- ing frosts that occur as early as the first week in October. Notwithstanding the possibility of secur- 134 FORAGE CROPS ing two crops, the yields of each are often as large as can be obtained from the larger- growing varie- ties. There are many other good varieties that possess in varying degrees the characteristics mentioned for this one. As a rule, the flint varieties are superior to the dent in the northern parts of the country. The smaller, quicker-growing varieties of the dent sorts are also satisfactory, although requiring much thicker seeding and a longer period of growth. Preparation of land The yield of the crop depends to a very consic- erable extent on conditions that are favorable for complete germination and very early growth. The importance of this point cannot be emphasized too strongly. Naturally, the preparation of the land and its treatment will depend somewhat on its condition and character. In the first place, if either clover or grass sod is used, it is generally good practice not to plow too deep, which is likely to turn up parts of the soil not thoroughly mixed with vegetable matter, and not in good physical condition. This admixture of subsoil has an unfavorable effect on quick and satisfactory germination. Therefore, relatively shallow plow- ing,— five to six inches,—is preferable. Plowing should be performed as early as it is ‘9108 OY} 0} OS¥IOJ W92IZ JO SMO} eA]OMY SuIpjots 136 FORAGE CROPS possible to get on the land, that the soil may be suitably compacted before the drying winds of spring absorb the moisture. Following the plow- ing, the tillage should be deep and thorough, both _to warm the soil and to make the surface as fine - as possible. When soils are loose and porous, the ‘ necessity for deep and repeated tillings are not so “great as when they are heavy and compact. If -the soil is not plowed until immediately preceding planting, it is likely to be cold, preventing quick germination; and should dry weather follow, the surface rapidly dries out and the plants will not absorb sufficient moisture from the lower layers to cause rapid and continuous growth. When the crop is planted on land that has not had a cover- crop, the recommendations may be modified to some extent; a little deeper plowing may be made, and less tilling is required to get it into first-class condition. Manures and fertilizers When the aim is to secure as large a yield of succulent food as possible, and of superior quality, it is absolutely necessary that the plants have an abundant supply of plant-food throughout the entire season. Therefore, even on good soils, the fertilization should be liberal. Manure may be placed on the surface in the fall, in which case it serves as a muleh during winter, absorbing mois- MAIZE FOR SOILING 137 ture, preventing washing and ensuring a complete distribution in the surface layers of the soluble plant-food; or it may be applied after plowing in spring, providing it is fine and thoroughly incorporated in the surface soil. These methods will ensure the largest return of the constituents in the crop, and they are particularly desirable when manures are used that contain but little litter. When manure is used, ten tons per acre applied broadeast will afford abundance of organic ma- terial, containing sufficient nitrogen in available forms to supply the early needs of the plant. It must be remembered, however, that no amount of manure or fertilizer can be substituted for early and thorough tillage, as tillage saves moisture. This is a matter of the highest impor- tance, for without moisture the plant-food cannot be dissolved and circulated through the soil. There- fore, whatever the method of manuring, the soil after seeding should be tilled, preferably shallow and as frequently as possible, until the plants are too large to permit further work. The fact that the plant does not make its most rapid growth in any case until warm weather begins, makes the necessity for early and large applications of quickly available nitrogen not so great as in the case of such crops as rye or wheat, or even oats, that make their most rapid growth much earlier in the season. With corn, the conditions are gener- 138 FORAGE OROPS ally favorable soon after planting for the change of organic nitrogen into available forms. The corn plant, however, requires a liberal supply of the mineral constituents; and while the application of manure will carry relatively large quantities of these, it is obvious that they cannot be so completely distributed as in more soluble forms, nor, unless the manure is placed in the row, can they be concentrated in such a way as to permit the plant to supply its needs easily and rapidly. Therefore, in addition to manures, a fer- tilizer rich in minerals is generally desirable. A fertilizer carrying 1 per cent of nitrogen, 12 of phosphoric acid and 10 of potash (made by mixing 250 lbs. ground bone, 500 lbs. acid phosphate, 250 lbs. muriate of potash), applied at the rate of 400 pounds per acre, will meet the requirements for minerals even under unfavorable conditions. This fertilizing, while seemingly heavy, is not more than should be applied, because the object is to stimulate as far as possible a continuous and rapid growth. The above remarks are made, of course, with eastern conditions in mind. In large parts of the West, these heavy applications will not commend themselves to farmers in general; but even there the question of fertilizing is coming to be an important one, although the main demand may be for but one of the constituents. In the long MAIZH FOR SOILING 139 run, the question of applying plant-food is not regional. Seeding and tillage Methods of seeding vary widely, although it is recognized in all cases that the thickness of seed- ing should be proportioned to the possible available plant-food in the soil. On soils that are naturally rich and supplemented with the fertility constit- uents in available forms, thicker seeding may be made than when conditions are not so good in respect to food. A good method of seeding corn is to plant in drills, from two and one-half to three feet apart, and the plants from eight to ten inches apart in the drill. The quantity of seed necessary to plant thus thickly, will range from twelve to fourteen quarts per acre, depending on the size of the grain. In branching varieties, the plants will be as thick as it is desirable to have them with the lighter seeding. Seedings thicker than this, either in rows or broadcast, as is frequently practiced, are likely to cause the crop to suffer from lack of moisture, if short droughts occur, even under very favorable conditions for obtaining plant-food. The size of the stalks under this thick seeding will be such as to cause the forage to remain succulent and palatable until the grain begins to harden. As already indicated, when large yields are to 140 FORAGE CROPS be secured, great care should be observed in the conserving of the moisture, and therefore the cultivation should begin about as soon as the corn is planted. Shortly after planting, the surface should be stirred frequently, preferably with a light harrow or weeder, until the corn is well started, when shallow tilling should begin and be continued as frequently as possible during the early period of growth. This frequent tilling will prevent the undue escape of moisture into the atmosphere, as well as assist in the decomposition and _ nitrifica- tion of the organic matter in the soil and manure. After the first crop is removed, a second one may be immediately planted, preferably without plowing but with a deep cultivation with a cutaway har- row. The corn stubs will interfere to some extent, but not seriously. The reasons for cultivating, rather than plowing, when the first crop is removed (say the middle or latter part of July), are, first, that quite as good tilth can be secured, and second, if the land is plowed at this season, it is frequently impossible to get the surface layers so thoroughly compacted and connected with the lower one as to permit free upward movement of water from the lower parts of the soil. It is essential, particularly in this second crop, that the germination should be quick and as complete as possible, and the early growth very rapid. The manures and ferti- lizers should be applied in the same way as for the MAIZE FOR SOILING 141 first crop, and the seeding and tilling should also be the same. Time of harvesting, and yields The time of harvesting maize for soiling pur- poses may begin as soon as the plant has fully tasseled, or even before, depending on the need for succulent forage. The largest amount of actual food or digestible nutrients will be secured if the harvesting is delayed until the ears have formed, and then continued until the glazing stage is reached. Therefore, the yields will vary widely, inasmuch as the proportion of dry matter in the early-cut forage is relatively very much less, and the water very much more than when the crop is nearly mature. Records obtained at some of the stations show that under normal conditions of sea- son more digestible matter, and that which is quite as palatable, may be secured from twelve tons of corn cut at the glazing stage, than would be secured in fifteen tons or more harvested before or about the time the plant is coming in tassel. So the yields may vary by the common, though not proper, standards of reckoning; and the fact that a crop will yield fifteen or even twenty tons of forage, as is frequently stated, is no indication that such crop is superior in content and value of total nutrients to one that yields twelve tons. It is not desirable to prolong the feeding of the 142 FORAGE CROPS green forage until the ears have matured, as the tendency of the animals will be to eat the ears in preference to the other parts of the forage, and the master cows will appropriate an undue pro- portion and possibly be injured by an excessive supply, particularly if the forage is distributed in the field. For soiling, the forage should preferably be used before the grain has hardened. Composition and value of crop Corn in its best stage for green forage contains, on the average, and for all varieties, 20 per cent of dry matter. This dry matter is much richer in carbohydrates than wheat or rye forage. There- fore, so far as total nutriment is concerned, it is much superior to these crops, as well as to the millets, sorghums or kafir corn. That is to say, a larger proportion of feed in a succulent and digestible form is contained in a smaller amount of forage. Usually from forty-five to fifty pounds per day will supply the needs for roughage, as compared with fifty to seventy-five pounds of millet or either saccharine or non-saccharine sor- ghums. Corn can be utilized through a longer period than any other crop. Therefore, the plantings should be made at different times; and as any one seeding can be used for a period of fifteen to SWEET CORN 143 twenty-five days, the plantings should be made two or three weeks apart. Of course, a similar succession may be obtained by the use of the early-maturing and the late-maturing varieties, but the later varieties do not make so good green forage as the early ones.

Two crops of ten tons each would yield about four tons of dry matter per acre of a highly digestible and very satisfactory forage. SWEET CORN FOR GREEN FORAGE Owing to the very palatable nature of sweet corn, it is frequently recommended for green for- age, If suitable varieties are chosen and planted 144 FORAGE CROPS at the proper time, it is a very useful crop, al- though the experience of careful experimenters shows that, on the whole, the yield of feed is relatively very much less than from the regular field varieties, the range being from four to ten tons per acre, with an average of about six tons. A variety of sweet corn that gives a satisfactory yield is rather slower in development than other corn, owing largely to the fact that the seed does not germinate quickly nor the young plants grow vigorously until the season is well advanced. Of the suitable varieties, Stowell Evergreen is one of the most generally satisfactory, since it is a large, rank grower, with abundant foliage. It should not be planted until the season is well advanced, say the latter part of May, for the Cen- tral States, and the land should be thoroughly well prepared, as pointed out for other kinds of maize. When used primarily for forage, sweet corn may be fertilized or manured, as indicated for the Thoroughbred White Flint, and cultivation should be practically.the same. A great advantage that many dairymen find in the growing of sweet corn is that they may sell a large proportion of the ears, when the prices are satisfactory, and still have a very good for- age left, as the stalk remains palatable for a con- siderable time after the ears have been removed. There is no question as to the superjority of the SWEET CORN FOR SOILING 145 sweet varieties for forage, as the animals certainly are able to utilize the nutrients to the fullest ex- tent; and because of their extreme palatability, they exert a very favorable effect on the system, encouraging, apparently, a larger and better use of the accompanying feeds, as an increased flow of milk usually follows when sweet corn forage is sub- stituted for field varieties. Because of the greater palatability of the*sweet varieties, however, ani- mals are likely to overeat. From fifty to sixty pounds per head per day should be the limit of use; it is important that the distribution in the feeding lot should be so made as to prevent any one animal from securing a larger quantity than this. The composition of sweet corn does not differ materially from that of the field varieties, although it is more palatable and undoubtedly more com- pletely digested.

The cost of the sweet corn forage is greater, owing to the much higher price of seed. DRIED CORN FODDER An advantage that corn possesses, and which makes it superior to practically every other plant, is the fact that, if the crop is not required in its green stage, it may be dried and used for fodder. While it contains a high content of dry matter, it cures readily, and for certain classes of feeding furnishes roughage that is unexcelled. Seeding and harvesting The varieties used for fodder may be practically the same as those recommended for green forage, although the seeding may be slightly thicker, as DRIED CORN FODDER 147 the advantage of earing is not so important. In fact, a better quality of fodder will be secured when a minimum number of matured ears are formed. The time of cutting will depend somewhat on the character of growth, but the largest amount of dry matter will be obtained when the maize plant is practically mature, and if the seeding has been thick enough the curing at this stage can be accomplished readily. When there is danger of shortage of other winter roughage, corn is often planted late to supplement the regular supplies, in which case the crop is not always sufficiently mature before it is time to harvest. This will result in giving a crop that is very rich in diges- tible dry matter, but that is difficult to cure. However, if it is placed in small shocks, it will soon dry out; it should be removed from small shocks to large stacks or to the barn before the heavy storms of winter begin. Composition and value of dry corn fodder The composition of well-cured corn fodder is such as to make it a most excellent and nutritious food, and it is readily eaten by all farm stock, especially if cut fine. The amount of dry matter in field-cured fodder is about 75 per cent, and it is nearly as rich in protein as timothy hay, and con- 148 FORAGE CROPS tains very much less crude fiber. A good crop of corn should yield about three tons per acre. A mistaken idea is that the thicker the corn is seeded, the larger will be the yield of food per acre, and in many instances the corn is sown broadeast or planted exceedingly thick in the row with this notion in mind. While the forage will be a little more digestible and a little richer in pro- tein under this treatment, the yield of total nutrients per acre is usually very much less than if planted in the ordinary way and tilled, since the thick-seeded crop will be likely to suffer from lack of moisture, and it is much more exhaustive per unit of dry matter on the fertilizer constituents of the land. It is not a desirable practice to broad- east corn unless for hog pasture, or as catch-ecrop, and even then the advantages are not always apparent. Sweet corn dry fodder As already pointed out, sweet corn is an excel- lent source of nutrients, because it does not grow quite so coarse as the ordinary field varieties, and because it is very palatable and contains a highly digestible form of carbohydrates. As in the case of other fodders, if grown primarily for dried fodder, the seeding should be relatively thick, so as not to permit too heavy earing, although the presence of ears is not so undesirable as in field STOVER 149 corn. Sweet corn fodder is more likely to mold than field corn, and greater care should be exer- cised in harvesting; it should be thoroughly cured in the field, and then stored in a dry place. If entirely freed from outside moisture, and thoroughly air-dried, it may be packed tightly in the barn without danger of injury. The neces- sity for cutting it fine, when fed, is not so great as for other corn, since animals will eat it readily without cutting, due to the softer stalk and its palatability. CORN-STALKS OR STOVER Stover is the stalks remaining after a corn crop has been harvested of its ears, the crop having been grown for the grain. There is great waste of stover throughout a large area of the country; it is certain that this waste would be saved if its food-values were better understood. The coarse stover has a high feeding-value, which will justify much greater care in its handling and storage. The feeding-value of a ton of stalks is more than half the value of a ton of timothy hay that is har- vested in its best condition. Methods ot curing and handling corn-stalks Methods of handling stover differ widely in different sections of the country. In the eastern 150 FORAGE CROPS and northeastern states, the corn is usually cut and shocked, and when the ears are dry enough to erib, the corn is husked and the stalks are re- shocked in the field until cured, and then either carted to large stacks or stored in the barn. This is an economical method of curing and saving the crop. In the South and parts of the West the practice is merely to “top” the stalk, and the leaves and stalk below the ear, with the husks, re- main standing in the field. This practice results in a large waste of valuable material. In many of the western states, only the ears are removed from the standing corn and the staJks are not harvested; the only value gained from the stover is that which may be secured by the animals following the husk- ers, and even then probably not one-third of the food is utilized. Another source of loss of fodder, even though the corn is husked and the stalks shocked, oceurs when the shocks are left in the field until they are needed for food. By this method great losses occur, due to the mechanical removal of the leaves by weather, to changes in chemical composition, and to the removal of a large proportion of the best of the material by wind- and rain-storms; besides, the rain and snow soak the outer parts of the shocks, and these parts become frozen, not only rendering them unpalatable but making it im- possible to remove the entire product to the barn. Corn-husker and shredder at work. Fig. 32. 152 FORAGE CROPS Methods of using; yield The best method of using stover is to cut it fine, or to shred it and feed the animals liberally, allow- ing the unpalatable parts to be used as bedding. In this way the best of the feed is utilized and the manures are saved and improved. The yield of stover will naturally vary accord- ing to the variety and the character of the crop. The ratio between ears and stover is not uniform, but with a yield of 100 bushels of ears there is usually about two tons of stover, which contains about 60 per cent of dry matter or feed per acre, equivalent in value practically to a ton of timothy hay. CHAPTER IX CORN FOR SILAGE THE prime means of utilizing the green corn crop is in the form of silage, particularly in dairy districts. By this use the largest amount of diges- tible feed may be obtained per acre, and in a suc- culent and highly palatable form. Since the use of the silo became an important question there has been very great improvement in the growing of corn for silage and in its storage. In the early his- tory of the silo it was recommended that corn of the larger varieties be planted very thickly, and be stored before it had nearly reached a stage of maturity. The consequence was, that, while large crop yields were secured, the high content of water and the consequently low content of dry matter were detrimental both in increasing the cost of handling and the difficulties of its preservation; the feed value was not increased, and wastes from decay in the silo were very serious. Investigations on the growing of corn and ensiling it have shown that the general principles involved in the growing of forage, as already pointed out, are quite as applicable in the growing of corn for silage as for soiling or for fodder. (153) 154 FORAGE CROPS Varieties of corn for silage For the eastern, central west and southern states, the larger-growing varieties, as the South- ern White, Horse Tooth, Mastodon, or those gen- erally recommended by seedsmen, are preferable, giving a larger yield of actual dry matter per acre than the smaller- growing varieties, if only they mature sufficiently in average seasons before frost. Farther north, the flints, as Thoroughbred White, or the ordinary yellow varieties, and a number of the quick-growing dent varieties, are recom- mended, because the crop can be more completely matured before danger of frost. Preparation of land, and seeding As in the case of other forage crops, the prepa- ration of soil is very important. Early plowing, and a deep and thorough preparation of land are important in securing a quick and complete germi- nation and rapid early growth. Manuring should be liberal and supplemented by fertilizers. While all this is expensive when large areas are grown, nevertheless it is a paying procedure because of the very much larger quantity of feed material that may be grown per acre. It costs no more, for example, to buy land, to furnish seed, to plow, and to make the ordinary cultivations for a crop MANURES FOR SILAGE CORN 155 of twelve tons than for a crop of eight tons; proper manuring will frequently make this differ- ence in yield, other things being equal. It is rec- ommended that manure be applied either in the fall or winter on sod, at the rate of eight to ten tons per acre, or in spring after the land is plowed and previous to planting. There is no crop that will utilize to such good advantage the coarse ma- nures as corn; it is a great forager, and at the season of its greatest demands, when it makes its most rapid growth, the coarser organic manures are more readily changed and converted into active substances than would be the case with such crops as wheat or grass, that mature early and require a large proportion of their food before changes in the organic compounds can take place in the soil. It is essential, also, in order that the nitrogenous material of the manure may be completely utilized, that abundance of minerals shall be at the disposal of the plant. Therefore, a liberal fertilization with available forms of phosphoric acid and potash, is also recommended. Usually, an application of 300 pounds of acid phosphate, or its equivalent of phosphoric acid from ground bone, when there is an abundance of organic matter, and 100 pounds of muriate of potash, broadcasted, will very materially inerease the yield. An old practice, which has many points in its 156 FORAGH CROPS favor, is the dropping of fine manure in the hill at time of planting. The advantage of this method is, that the organic substances will ferment quickly and warm the soil, and thus encourage a quick germination; and a more rapid early growth is to be obtained, as the plant makes a quick start, gets away from insects and makes possible an earlier cultivation of the land. Tillage The methods of cultivation have been greatly improved in recent years, owing to a more careful study of the nature and the composition of the plant. While the old notion that cultivation pre- vious to planting is the best, is true to some extent, tillage has for one of its primary purposes the destruction of weeds in addition to the conser- vation of moisture, and this is accomplished by frequent and deep tilling subsequent to planting as well as previous to it. Immediately after the crop is planted, the surface should be stirred to destroy the young weeds in the rows, and to pre- vent the rapid escape of moisture. This can be accomplished by harrow or weeder. As soon as the corn is three or four inches high, the ordinary cultivator should be run through the row, the first one or two cultivatings being three or four inches deep, then gradually shallower, as the plant grows, SEEDING OF SILAGE CORN 157 to avoid cutting the roots, which soon ramify in every direction and fill the whole surface soil. These feeding roots should not be disturbed. Seeding The quantity of seed to sow will depend to some extent on the variety and the character of soil. On good lands, the large-growing varieties will probably give the largest yield if planted in rows from two and one-half to three feet apart, and the plants six to eight inches apart in the row. This will require about fourteen to twenty quarts of seed per acre, depending on the size of the grain. Seedings as thick as this will permit of a very considerable setting of ears, although not so large a proportion as to make the silage too rich in digestible carbohydrates. Time of cutting, and yield The best time of cutting is when the ears are beginning to harden, and while the lower leaves are still green. Of course, the season will influence this point to a considerable extent. In dry seasons, the lower leaves will become dry before the ears have reached the proper stage of development, although there will be appropriation of food by the plant so long as any green leaves remain; 158 FORAGE CROPS therefore, the stage of maturity of the ear is the best guide as to time of cutting. When cut at this stage, a good yield will reach twelve tons per acre. This does not seem large, yet the crop will carry about 25 to 28 per cent dry matter, or an equivalent of over 6,000 pounds of actual dry substance per acre, which is greater than can be produced by any other cereal crop. When much larger yields of dry matter than this are reported, the probabilities are that it is pro- duced on a smaller area specially treated, or in an exceptional season, or under unusual conditions of soil and climate. The reported average yields of twenty, twenty-five and thirty tons per acre, which are often noted, are evidently based on forage containing very much less dry matter. When it is remembered that it is a question not of tonnage of silage corn, but of dry substance that is involved, the grower should not base his expectations of feed production on statements of extraordinary yields, as he will surely be disappointed. If a crop has become too dry to go into the silo in the best condition, the wetting of it may help somewhat to preserve the silage, but it must be kept in mind that water cannot take the place of the natural juices and the activity of living cells. If leaves and stalks have become dry, the cells have become filled with air and the adding of water can only partly displace it. The chief help ENSILING CORN 159 of water is in softening the tissues, and in aiding it to pack more closely. This method is often used, however, and, if the conditions in other respects are favorable, good silage results. Frosts often come earlier than usual, and the corn is frozen before it can be ensiled. When this happens, it is best to cut the corn as soon as pos- sible thereafter, and before the leaves are entirely dry, cutting in rather large heaps, so that it will not dry out too rapidly in the field. By,care in these respects, frozen corn can be fully utilized for silage. Storage in the silo In the ensiling of corn, great progress has been made, chiefly in the form and construction of the silo. It has been demonstrated that the one crucial point in the saving of corn in a silo, is that the product shall be put in a building or receptacle that is practically air-tight. A round structure is more easily made tight and it presents the least friction against proper settling and packing. It may be made of staves, or frame, or brick, or stone, or of any material that will accomplish the purpose, namely, the prevention of the access of air. Square silos cannot be so tightly constructed, and the penetration of air when the silo is open is greater. It is impossible to pack closely in the corners. 160 FORAGE CROPS While the various styles of silos here mentioned may all be good, there are several objections to stave silos that are intended to be permanent buildings out-of-doors. The staves are liable to shrink and the hoops to loosen when the silo is empty. In many instances, they are blown down in high winds, and even if not blown down they are racked and get out of plumb. It is also diffi- cult securely to anchor a permanent roof, and to connect permanently the staves with the founda- tion. It does not pay, in the long run, to make cheap staves silos. An all-wood frame round silo is a type that has given excellent satisfaction, especially when care has been given to securing a good lining, which can be accomplished only when it has a sufficient diameter to permit of “springing” the lining boards in place, rather than to have the lining perpendicular. There should be at least three layers of the wooden lining, with paper between, the first nailed on the studs, then a lining of tough building-paper; the second layer nailed so as to break joints, and another lining of paper; and the third nailed, breaking joints again. To prevent the decay of the inside lining, it should preferably be treated with a mixture of gasolene and coal tar, rather than paint. This preserves the wood, to some extent prevents the entrance of moisture, and is not brushed off by the pressure of the silage as paint is likely to be, FILLING THE SILO 161 As to cutting and filling, there has also been considerable gain in our knowledge and practice. It is now thought that the finer the corn is cut or shredded, the better, primarily because there is more even distribution of the parts of the ears and stalks, and because the finer the material is cut the more readily and evenly will the settling take place, thus again preventing the ready access of air. It has been demonstrated, also, that the neces- sity of very rapid filling of the silo, and the sub- sequent pressure, are not such important consid- erations as was formerly supposed. Corn may be ensiled at the convenience of the farmer, providing the fermentation does not proceed so far as to cause rotting between times of filling. The development of heat in the silo cannot be avoided, and does not necessarily occasion great loss of substance, although fermentation always results in more or less breaking down of substance, and in some loss; in the case of corn, this loss is chiefly in the carbohydrates. When the work can proceed steadily, from eight to fifteen tons per day may be put in small and medium-sized silos, but, as already indicated, the silage should not stand more than two days between successive fillings. The importance of thoroughly compacting silage at the time of filling the silo is not usually sufficiently well understood. The thorough tramping not only enables a much K x 162 FORAGH CROPS larger quantity of silage to be put in, but it expels at once a very large volume of air, which, if allowed to remain, prolongs the changes. It should be tramped well around the sides because the lateral pressure of the silage tends to develop fric- tion against the walls, which prevents its settling. In building a silo, it should be as deep as it is practicable to make it. The advantages of a deep silo are that the largest quantity of feed per cubic *TABLE GIVING THE APPROXIMATE CAPACITY OF CYLINDRICAL Sinos ror WELL-MaTURED CoRN SILAGE, IN TONS Inside diameter in feet 15 16 17 18 19 20 21 22 23 24 25 26 58.841 66.95] 75.58] 84.74) 94.41} 104.6 | 115.3 | 126.6 | 138.3 | 150.6 | 163.4 | 176.8 62.90) 71.56] 80.79} 90.57] 100.9 | 111.8 | 123.3 | 135.3 | 147.9 | 161.0 | 174.7 | 189.0 67.35] 76.52] 86.38] 96.84) 107.9 | 119.6 | 231.8 | 144.7 | 158.1 | 172.2 | 186.8 | 202.1 71.73) 81.61} 92.14] 103.3 |115.1 | 127.5 | 140.6 | 154.3 | 168.7 | 183.6 | 199 3 | 215.5 76.12} 86.61] 97.78] 109.6 | 122.1 | 135.3 | 149.2 | 163.7 | 179.0 | 194.9 | 211.5 | 228.7 80.62] 89.64 103.6 | 116.1 {129.3 | 143.3 | 158.0 | 173.4 | 189.5 | 206.4 | 223.9 | 242.2 22 8 BR ES | pent, toot 85.45] 97.23) 109.8 | 123.0 | 187.1 | 151.9 | 167.5 | 183.8 | 200.9 | 218.8 | 237.4 | 256.7 90.17) 102.6 | 115.8 | 129.8 | 144.7 | 100.3 | 176.7 | 194.0 | 212.0 | 230.8 | 250.5 | 270 9 is] 3 94.99} 108.1 | 122.0 |136.8 | 154.4 | 168.9 | 186.2 | 204.3 |"223.3 | 243.2 | 263.9 | 285.4 99,92] 113.7 | 128.3 | 143.9 | 160.3 | 177.6 | 195.8 | 214.9 | 234.9 | 255.8 | 277.6 | 300.2 on Ss S&S @ -|105.0 }119.4 | 184.8 ) 151.1 168.4 | 186.6 | 205.7 225.8 | 246.8 | 268.7 | 291.6 | 315.3 -| 109.8 |124.9 | 141.1 | 158.2 | 176.2 | 195.2 | 115.3 | 236.3 | 258.2 | 281.8 | 305.1 | 330.0 {115.1 | 185.9 | 147.8 | 165.7 | 184.6 | 204,6 ) 225.5 | 247.5 | 270.5 204.6 319.6 | 345.7 wo 3 yf In this table the horizontal lines give the number of tons of silage held by a silo having the depth given at the head of the column. *Bulletin No, 83, of the Wisconsin Agricultural Experiment Station, CUTTING SILAGE CORN 163 foot can be stored; the silage packs tighter and loss is prevented at the surface when feeding; and when closely tramped against the wall, air is excluded and the silage keeps better than when it is shallow. The quantity of silage that may be stored in a silo increases in a higher ratio than the depth increases; a silo thirty-six feet deep will store nearly five times as much as one twelve feet deep. Cutting corn for the silo may be done either by hand or by the “self-binder.” When the crop is large enough, the latter is preferable, because a team may do the cutting late in the afternoon or early morning, and thus reduce the number of men needed. Besides, the binding of the corn makes it much easier to handle, both in loading and in _ feeding. There are a number of excellent silage cutters. The mistake commonly made by farmers is in getting those that are too small; it is better to have a cutter a little larger than is needed. Few should have cutting blades less than fourteen inches long. It is also very important that the power to drive the cutter should be considerably in excess of its guaranteed capacity; especially is this the case when blowers are used, instead of carriers, as it is important to have not only a high speed but a steady power. After the silo is filled, the top should be covered with earth or other material, which will 164 FORAGH CROPS pack tightly, so as to prevent the ingress of air. Many farmers recommend the thorough wetting of the surface, a light covering of soil, and the seeding of oats, as the cheapest and surest way to make the silo tight. While there is consider- able loss under the very best methods of handling and packing the corn in the silo, chiefly falling on the carbohydrate group, these losses have been shown to be no greater than those which take place in the common handling of the corn after it has been cut and husked. The changes in the silo, other than direct losses of carbohydrates, are due chiefly to modifications in the nitrogenous nutri- ents, the albuminoids being changed into other forms, even though the feed value is not seriously reduced. In the construction of the winter silo, the size should be so adjusted to the number of cattle as to allow a removal of about two inches of the surface per day. In the summer silo there should be a re- moval of three to four inches, otherwise the heat- ing or fermentation which begins as soon as the surface layer is removed, will result in consider- able changes, and consequent reduction in the food value of the silage. What is termed “sweet silage” is possibly a misnomer, although there is great difference in the composition of silage made and used under the conditions here outlined. The development of acid is very rapid, if the air is FHEDING OF SILAGE 165 allowed to come in contact with the silage for reasonably short periods. The amount of silage to feed The quantity of silage to feed should be regu- lated to some extent by the kind of silage and the size of the animals. It should never serve as the exclusive food, but mainly to supply carbohydrate roughage. From thirty to thirty-five pounds per day, containing say 28 to 30 per cent of dry matter, are sufficient for an animal of 1,000 pounds live weight. The feeding of silage should be accompanied, of course, by the use of the proper fine or concentrated feeds, and preferably with a little dry material, as cut corn-stalks or hay. When fed in this way, the results are alto- gether good. There have been no genuine investigations showing that silage causes any injury, when properly fed, or is in any way deleterious to the health of the animals, or unfavorably affects milk, butter or cheese. On the contrary, the health of animals in winter is usually better under the use of the succulent food, and the returns per unit of dry matter for silage used in the dairy, compared with the dry fodder corn, are about 12 per cent greater. These results have been secured in actual experiments to determine the relative 166 FORAGH OROPS value of the two kinds of forage. There is no question, therefore, of the value of this method of preserving corn for food. Whenever farmers have a sufficient number of dairy, beef or young cattle to warrant the building of a silo, there will be no question as to the advantage of the system. The gains in the making of silage over the using of the grain and stover, are, (1) the preven- tion of mechanical losses in the harvesting of the corn; (2) the advantage of the removal of the entire crop at one time, so as to permit of a more rapid growth and development of cover-crops, which are so important in the conservation of fertility; (8) reduction in actual cost of labor per unit of feed obtained, whig¢h will result when- ever farmers are equipped for the rapid handling of large quantities of material in a short time.

This group deserves even more attention than it is now receiving, because of the relations of the plants to nitrogen. The plants belonging to the legume family include the various clovers, peas and beans. All these plants have a souree of supply of plant-food that is not acces- sible to most other plants, particularly not to the cereal plants. It is well known that after a crop of clover the land, as a rule, produces a better growth of corn, or other cereals, than when such a crop follows a grain or a grass crop. It was thought for a long time that this improvement in land was due to the greater proportion of root substance in the surface soil, because the plants root deep and gather food from the lower layers, storing it in the thickened roots. The soil improvement was not attributed to their power of gathering nitrogen from the air until careful experiments showed that the soil nitrogen was not consumed but rather in- creased by their growth. The fact that clover gives better returns as a stock feed than an equiva- lent weight of timothy was also known for a long (167) 168 FORAGE CROPS time, and investigation of the composition of the two showed that this difference was due to a larger proportion of nitrogenous substance in the clover than in the timothy. It is now known that the individual members of this group of plants possess the peculiar property of being able to secure the important element ni- trogen, in part, at least, from the air. Therefore, they may not need nitrogenous fertilizers after they are well established, and they may add to the nitrogen content of the soil when they are returned to the earth. The advantage of leguminous crops to the feeder lies in the fact that the plants themselves contain a larger proportion of nitroge- nous matter than those of the grass family, and thereby may be used to supplement other foods and to reduce bills for purchased and concentrated feeds. One can more profitably utilize the carbo- hydrates usually contained in excess in other plants; and he is relieved of some of the necessity of purchasing nitrogenous fertilizers to increase the growth of the cereal crops. Soil inoculation While leguminous crops possess this superior advantage in the ability to appropriate nitrogen, it must be remembered that this power 1s not constant for all soils and under all conditions; but in order INOCULATION FOR LEGUMES 169 that this peculiar function may be exercised, it is necessary that there shall be present in the soil certain organisms which attach themselves to the roots of the plants. The presence of these organ- isms is indicated by the formation of tubercles or nodules on the roots, which range in size on differ- ent kinds of plants from that of a pin-head to that of a pea. When these nodules are not present, it is usually an indication that the proper organisms are absent and that the legumes, in common with other plants, must derive their nitrogen from the soil; and thus, from the standpoint of accu- mulation of nitrogen, they are probably no more useful than the cereal or other crops. Investigations of the life-history of these minute organisms show that there are certain conditions unfavorable for their growth and development, which explains why they are absent in many soils For example, it has been shown that they are likely not to be present in soils that are poorly drained, and when air cannot penetrate and circulate freely. It has also been found that an acid-condition of soil is not favorable to their growth. They are also liable, even if originally present, to be destroyed at certain periods if soils are allowed to remain uncultivated for some time. In other words, in undrained, acid, and light sandy soils deficient in organic matter, the organisms are not so likely to be present as in those that are well supplied with 170 FORAGE CROPS organic matter, are neutral in their. reaction, and are well-drained; and these are the conditions, also, that are favorable for crops, providing suffi- cient food is present. Methods of inoculation In view of these facts, it becomes necessary, in order to secure the full benefit from the growth of leguminous crops, to see that the proper organisms are present. This may be readily accomplished by inoculation, or introducing the specific organism. Soils deficient in these organisms may be supplied by using earth from the fields in which they are known to be present. Experiments show that only a small quantity is necessary, if evenly distributed, to accomplish the purpose. From one to three hundred pounds of mixed soil, taken from dif- ferent parts of the field, will be sufficient for one acre, if sown broadeast and harrowed in. The soil should be taken from a field in which the same kind of crop has been successfully grown. The organisms will multiply when legumes are grown, will distribute rapidly, and be prepared immedi- ately to begin their helpful work. Once the organ- isms are present, there is little danger of their destruction under good farm practice. If the crops that are grown on this area are fed to farm stock, and the manure is used elsewhere on the farm, INOOULATION 171 the chances are that the organisms will soon be generally distributed. It is especially desirable that land be inoculated for alfalfa, if it has not grown alfalfa previously. Clover lands are not often inoculated. It often happens that in the growing of such plants as cowpeas and soybeans, the first crop will not show the tubercles, but the second one will be well supplied with them, indicating that the organ- isms may be introduced by means of the seed or the dust that goes with it. Some seedsmen now make it a practice in harvesting soybeans and cow- peas to pull them instead of cutting them, thus mingling more or less of the soil with the seed in the threshing. The organisms of different leguminous crops have recently been investigated by the United States Department of Agriculture,' and methods devised for providing suitable nutrients for them. As a result, cultures have been prepared and distributed, together with the food necessary for their early growth. The commercial cultures have not yet been successful in practice, however; but eventually good results may be obtained. The grower should remember that inoculation of the soil is only one factor in the growth of these plants. Good crops cannot be grown on poor, wet, or acid soils, or under unfavorable culture condi- 1 Bureau of Plant Industry, Bulletin No. 71, January, 1905. 172 FORAGE CROPS tions by inoculation alone; the other conditions of growth must also be made favorable. The amount of nitrogen gathered It does not follow that even when these organ- isms are present and all other conditions are fav- orable, all of the nitrogen in the legume crop has been gathered from the air. It has been shown that the plants preferably take soil-nitrogen rather than air-nitrogen. On good soils containing much available nitrogen, or directly well supplied with this element, the proportionate amount of nitrogen appropriated from the air will be much less than when the crop is grown on soils poor in nitrogen, even if inoculation has been made. The amount of nitrogen gathered by a crop, therefore, cannot be exactly determined, although, as just indicated, it is thought that the usefulness of the legumes as a means of acquiring atmospheric nitrogen and adding to the stores in the soil, is greater when they are grown on soils rather poor in this element. It has also been clearly demonstrated that the proportion of nitrogen gathered from the air, par- ticularly on poor soils, even when the proper or- ganisms are present, depends on the supply of the other necessary plant-food ingredients. Soils poor in nitrogen and uncongenial in physical character ‘NITROGEN-GATHERING 173 will not produce a large crop of any leguminous plant unless well supplied with phosphoric acid and potash. Therefore, in attempts to increase the protein supply of the farm by means of leguminous plants, it is quite as necessary to fertilize with the minerals as it would be to grow any other crop. This is entirely reasonable, as the mineral constit- uents cannot be secured from any other source than the soil and these are quite as essential to leguminous crops as to any others, or as the nitro- gen itself. Kinds of leguminous crops The family Leguminose, or pulse family, is very large and it is represented in the flora of all parts of the globe. Some of the legumes are trees, as locusts, red-bud, yellow-wood; others are bushes, as furze, broom, lead-plant; some are tall woody climbers, as wistaria; others are agri- cultural herbs, some of which are grown for for- age, as alfalfa, clovers, cowpea, soybean, velvet- bean, vetches, pea, and these are to be considered further in the three chapters that follow. Fig. 33. Oats-and-peas. CHAPTER XI ~ COMBINATION CROPS WITH LEGUMES VaRIoUS crops may be grown in combination, in which leguminous plants occupy an important place. The combination crops with legumes afford a very perfect balancing of nutrients, they often increase the acre yield, and sometimes they afford the best means of utilizing land. These combina- tions are of three groups: (1) Hardy annual legumes (peas and vetches) grown with cool-sea- son cereals; (2) tender annual legumes (cow-peas, soybeans, velvet beans) grown with warm-season cereals; (3) mixtures of clovers and grasses. When carefully managed, these combinations give the desirable results of each of the ingredients and afford another resource to the stock feeder. OATS-AND-PEAS FOR FORAGE The oats-and-pea crop is. grown primarily for use as green forage, or for soiling, and it is one of the most serviceable in any forage crop rotation, supplying food when other crops are not usually available, and also making an excellent substitute for hay when it is not needed for green forage (175) 176 FORAGE CROPS purposes. The object of making a mixture of oats and Canada field peas is to improve the quality of the crops, as well as to increase the yield, making both the total quantity and the character of the nutrients superior to those that would be secured by using either of the crops alone. The variety of oats to be used should be a strong and vigorous grower, well adapted to the locality and to climatic conditions. Any variety that has proved itself superior as a grain- producer may be safely used for green forage. It is an advantage to select the best seed when planting for forage crops, — quite as important in the growing of forage as in the grow- ing of grain or seed. There is wide difference in the varieties of the Canada pea. For average purposes, probably the Golden Vine is as satisfactory as any, because it is more generally grown and the seed is cheap, and because a smaller quantity is required per acre. It is a medium-early variety. Early varieties that are very satisfactory are Canadian Beauty and Black- Hyed Marrowfat. Late varieties are Green-Scotch, Greenfield and Prussian Blue. These later varieties naturally produce a larger crop, as the period of growth is somewhat longer. Where hot weather comes on early, medium or medium-early varieties are superior. It is safer to plant a distinct variety than to depend on mixtures of various kinds, which are likely to mature unevenly. OAUS-AND-PEAS 177 Preparation of soil, and manuring Oats-and-peas are usually grown on .land on which a cultivated crop has immediately preceded, although good crops may be obtained on sod land if it has been plowed in the fall or very early spring and deeply cultivated. The land should be well and deeply prepared, in order to furnish a deep seed-bed for the peas. The areas best suited to the crop are cool, moist lands. When the weather is cool and moist, the season is much more favorable than when hot and dry. This crop responds very favorably to applica- tions of yard manures. In fact, there is no other manure that will so well or so completely meet the requirements; the organic matter contained in it aids materially in the development of the soil bac- teria, and the soluble nitrogenous and mineral salts feed the plants abundantly in the early stages of growth. The manures should be broadeasted at the rate of eight to ten tons per acre after plowing, and thoroughly harrowed into the soil. When a smaller quantity of manure must be used, it may be fortified by an application of a good fertilizer mixture whose constituents have been derived from good sources and containing INUETO BOM <4, Sar ei ues Ge ah Se: ee 4 per cent Phosphoric acid (available) ...... 6 per cent Ota shi) sy citac® ee Be Gen eo hea ee aed, ae Se 6 per cent L “Avy IO} io Fuylos aoJ svad-pur-sywo FF ‘Bly OATS-AND-PEAS 179 This may be applied either broadcast, or drilled with the seed at the rate of 200 to 300 pounds per acre. Owing to the fact that the crop makes an early growth, the particular need is for an abun- dance of available nitrogen, Quantity of seed, and methods of seeding The quantity of seed used on good soils is gen- erally about one and one-half bushels of oats and one and one-half bushels of peas each per acre, although as thick seeding as two bushels of each has been even more successful on well-enriched soils. Many variations may be made in the pro- portions, however, to suit the various conditions of cost of seed, kind of soil and time of seeding. Sometimes increasing the peas to two bushels or two and one-half bushels, and decreasing the oats to one bushel, is practiced. The crop should be seeded as early in spring as it is possible thoroughly to prepare the soil. The earlier the crop is planted, the greater will be the likelihood of a perfect crop, as both oats and peas suffer in the hot dry days of summer. It is a com- mon practice to sow the peas from five to eight days earlier than the oats. Many growers recom- mend that the peas be plowed-in from four to six inches, in order that they may root deeply, and thus be better able to resist heat and drought. 180 FORAGE CROPS Many other successful growers prefer to use the ordinary grain-drill for the peas and plant them as deeply as possible, following with the oats a few days later, and before the peas have sprouted. The experience at the New Jersey Experiment Station, where this crop has been an important one for eight years and where different methods have been used in seeding, has shown that it is not a profitable practice there to expend the extra labor required in plowing-in the peas or in seeding the two plants at an interval of a few days. Quite as even distribution and as large yields have been secured when the oats-and-peas have been mixed in the grain-drill, and all seeded together. It is important in any case that the seed be distributed evenly. Time of cutting outs-and-peas When seeded as early as it is possible to pre- pare the land, the first cutting for green forage will be ready in about two and one-half months. Because of its good proportion of nutrients, it may be used as the exclusive source of food for dairy cows, although this is not a desirable practice when it is the purpose to keep the animals up to full standard of production, as it would require about 100 pounds of the forage per day.! The best time for cutting is when the oat-grain 1 New Jersey Experiment Station Bulletin, No. 130 *sjuetd qoq Jo YAMOAS snosos1a W “Sulplos 1oJ sevad-pue-sqwQ ‘cg “Sy g great vigor of the peas. Oats-and-peas, showin Bod OATS-AND-PEAS 188 is in milk and the peas are forming pods; at this period, the largest amount of digestible matter may be secured. Because of the rather slow maturity of the crop, particularly if the weather is favorable, a single seeding of oats-and-peas may furnish supply for eight to ten days, providing cutting begins a little earlier than this, or when the oats are just headed out. When it is desirable to continue the feeding longer, a second seeding is usually made about ten days after the first. In ordinary seasons this will be ready eight to ten days after the first planting. A third seeding made eight or ten days later than the second is likely to be ready for use relatively earlier, however, owing: to the more rapid development of the crop as the hot and dry weather advances. In recent years a plant-louse has made its appearance in the eastern and southern coast states, and has been a very serious pest, attacking the peas and practically ruining the crop. Where this pest is present, the later seedings should not be made, as it attacks the plants at the end of June or the first of July, when early seedings have reached the cutting stage, and before later seed- ings have reached full development. When an abundance of fertilizer has been used, the plants are better able to resist or outrun the attacks of the insect. 184 FORAGE CROPS Yield, uses, and quality of crop The yield varies widely, ranging from six to twelve tons per acre. The early cuttings are not rich in dry matter, although the average is higher than for some other forage crops. The oats-and- peas crop gives a relatively higher percentage of protein than is obtained in wheat, rye or grasses, and it serves a very good purpose as a balanced ration. This crop also makes most excellent hay, pala- table for all kinds of farm stock, and much richer in the digestible nutrients than timothy, though not so rich in protein as clover. It should be cut for hay when at its best for forage, namely, when the oats are in the milk stage, and when the peas are forming pods. A larger yield of dry matter may be secured by allowing the two crops to ripen, harvesting and threshing the mixed grain crop, grinding the grain and using it for feed and using the straw as rough- age. The expense of this practice is much greater than that of hay-making, and the yield of diges- tible matter has been found to be no greater. An experiment at the New Jersey Station! to test this point showed that while the cured grain crop gave a larger yield of total nutrients than the crop cured as hay, the expense of the former method was 1Annual Report for 1901, p. 278 Oats-and-pea hay. Fig. 37, 186 : FORAGE CROPS much greater. The hay cost $8.24 per ton, and the oat-and-pea feed, $22.60, and the oat-and-pea straw, $6 per ton. The use of five pounds of the straw and seven pounds of the oat-and-pea feed resulted in 2.6 per cent larger yield of milk than fourteen pounds of the hay, although the feed cost of milk per hundred was 61.6 cents, when the oat- and-pea ration was fed, and 49.9 cents when the oat-and-pea hay ration was fed. The experi- ment showed clearly that both rations are palatable and digestible, and can be successfully used as partial substitutes for purchased feeds, although indicating the greater economy as a source of nutrients of the oat-and-pea hay. Allowing the crop to ripen, therefore, is not a profitable prac- tice, excepting when labor is abundant and cheap, or when it is more desirable to produce fine feeds than to purchase them.

This proportion is frequently desirable, depending on the relative price of seed and adaptability of soil. The forage and hay will be much richer in protein than is given in these analyses. When this crop is seeded primarily to supple- ment natural pastures, it is often used as pasture rather than as a soiling crop. This is a very waste- ful practice, as under the best conditions of pas- turage not more than one-third to one-half of the actual food will be used by the animals. Observations of the effect of feeding of oat-and pea forage to dairy cows show that it exerts a very favorable influence on the physical quality of milk. When farmers are raising their own milk and selling it to special customers, there are very great advantages in using this crop, either as green forage or as hay. OATS -AND-VETCH The methods or practice used in the growing of oats-and-peas apply in the case of oats-and- spring-vetch (Vicia sativa). This crop is not so palatable as oats-and-peas and has not been so generally used. The chief difference in manage- ment is in the quantity of seed used per acre. Thus far, the seeding of one and one-half bushels of “BulIos 10y Yoiea-Suyads-puy-sywoQ ‘ge “Sig OATS-AND-VETCH 189 oats and three-fourths of a bushel of vetch has been very satisfactory. The vetch makes much more leaf, and is not so firm a grower as the pea, but under favorable conditions it will make a large yield. It is not open to the disadvantage of being attacked by the pea-louse, and thus will serve in combination with oats when later seedings of oats- and-peas are found to be undesirable. The method of harvesting and feeding are the same as for the oats-and-peas. This crop also makes an excellent hay, the vetch contributing the protein in larger proportion and making a food rich in nitrogenous nutrients. When the vetch is allowed to mature, it shells rapidly, and unless care is used may prove a nuisance by volunteering as a weed. BARLEY - AND-PEAS For late feeding, a combination of barley and Canada field peas is desirable, as the pea makes a luxuriant growth in late fall and is not injured except by heavy freezing; and the pea-louse, which is so destructive to the spring-seeded Canada pea, usually does not attack the fall-sown crop. The quantity of seed should be about one and one-half bushels of barley and one and one-half bushels of the pea, seeded in the same way as oats-and-peas, preferably from the first to the middle of August. 190 FORAGE CROPS The composition of this. product does not differ materially from that of oats-and-peas, although, owing to the fact that it does not mature, it is naturally a little richer in protein than the oats-and-peas. It can be fed in the same way, except that a smaller quantity should be used,— from forty to fifty pounds per day. Where this crop can be successfully grown it is very useful, as it lengthens the soiling period by at least two weeks. WARM-SEASON COMBINATIONS In addition to such combinations of soiling crops as oats-and-peas, oats-and-vetech, rye-and- peas, there are others which at times at least are advantageous, although experiments have not yet been sufficient to determine whether under all cir- cumstances it is advisable to use them. The leading crops that may be used for these combinations are: corn, sorghum, kafir corn and millet, seeded with cowpeas or soybeans. The advantages of the com- bining of these crops are (1) the production of a more nearly balanced ration; (2) the larger yield that may be secured per acre, when all conditions are favorable; (3) the greater certainty of a paying crop when conditions are unfavorable for one or the other alone. For summer soiling, the advantages of growing kafir corn with cowpeas or soybeans, or of barn- 2 *Yo19A JO puBys poos Y ‘YoJoa-1oyUTA-pue-ywouM ‘OF “SLI WARM-SEASON COMBINATIONS 193 yard millet with cowpeas, are usually abundantly apparent. With the latter combination, unless the season is very warm, the millet will mature earlier than the cowpeas, yet there is the advantage that the corn or millet supports the cowpea, making the cowpea easier to harvest, prolonging the period of profitable use, and providing a much better ration. Very excellent yields have been secured with these combinations. Kafir corn or millet may be utilized for a longer period than if either the kafir corn or millet were used alone, which is at times a matter of very considerable importance. In the case of maize-and-cowpeas or soybeans, the advantages of the combination are usually not so apparent, although in certain regions the com- binations have been found to be very desirable, and have been recommended particularly for silage, since the combined crop provides a practically balanced ration for winter feeding. The trouble is that if a sufficient quantity of nutrients is to be provided in a succulent ration made up of maize and cowpea silage, a too large quantity must be used in order that the animals may secure a suffi- cient amount of dry matter. A safer, although a slightly more expensive method, is to plant the maize-and-cowpeas separately, and make the cow- peas into hay. Silage and cowpea hay are not open to this objection, as the succulent ration need not exceed thirty to thirty-five pounds per day. M 194 FORAGE CROPS Sorghum-and-cowpeas, or sorghum-and-soy- beans, make an exvellent summer forage, providing the sorghum is seeded rather thickly and harvested before it has nearly reached maturity. The quantity of seed recommended for all these combination crops is one-half that used when each of the crops is grown singly. MIXED GRASSES AND CLOVERS On most farms in the dairy sections of the country, timothy, red-top and clovers (both red and alsike), and timothy and clovers are two mix- tures generally used for pasture and hay-making. When the purpose of growing forage crops is pri- marily to supplement natural pastures, this crop of mixed grasses and clovers serves a most excel- lent purpose in supplying the need in emergencies. In. many localities, the grasses are seeded in the fall with field crops, as with wheat or rye, and the clovers are seeded in early spring, either with- out covering or with light harrowing. When immediate and large returns are impor- tant, seedings may be made without cover-crop in the late summer or early fall. The best time of seeding has been found to be from the middle of August to the first of October, depending on the locality. At the New Jersey Experiment Station, many tests have been made as to methods and MIXED MBHADOWS 195 times of seeding, and it has been found that for that locality (which would probably be true for a large part of the East) this method of seeding in late summer without nurse-crop is a very desirable one, as the seedings may be made after other crops are removed, as, for example, after potatoes, oats, or even after the same grass mixture when the land has been plowed immediately after the hay has been removed, and cultivated frequently before seeding. It is not necessary that the land shall have been planted with wheat or rye, as is the general custom; the seedings are more liable to take when this old practice is not followed. The preparation of soil, and seeding Frequent and thorough cultivation of land dur- ing the entire preceding summer, accompanied by heavy fertilization, is strongly recommended, al- though this is not found to be feasible by all growers; the principle is correct, however, and whenever the areas are not too large and when the farmer has abundant capital for the purchase of fertilizers, it may be profitably followed. In general, however, the conditions do not warrant such an expensive mode of preparation and seed- ing, and a system has been developed at the New Jersey Station which is entirely practicable under what may be regarded as more extensive condi- Fig. 41.

By this method the land from which crops are removed early enough, is plowed in July and thoroughly and frequently tilled until about the middle of August; this frequent tillage destroys many weed seeds, ensures a thorough division of the soil particles, and conduces to the unlocking of plant-food and encouraging the growth and de- velopment of soil bacteria. When the main pur- pose in the use of either of these mixtures of grasses and clovers is to secure hay, and to have the land remain in permanent meadow, the use of yard manures immediately before seeding is not generally desirable, owing to the danger of adding weed seed, although the thickness of the seeding of grasses and the treatment of the fields in respect to top-dressing will overcome this danger to some extent. When it is found desirable to re-seed, it is not necessary that the sod be planted with other crops, but it may be at once re-seeded with the grasses, provided it is plowed immediately after the first cutting has been removed, and thoroughly tilled in the months of July and early August. This prac- tice will permit a continuous growth of a crop that is suitable for green forage, although grown pri- marily for pasture and for hay. The quantity of seed required will depend to some extent on the character of the land and its 198 FORAGE CROPS preparation. When the land is naturally good and well prepared, the quantity of seed may be rela- tively large; but if it is poor and in bad con- dition, a large quantity of seed will not encour- age a proportionately heavy growth, as a great number of young plants will perish because of the lack of a proper medium for their growth and nourishment. The following seed mixture has been used with very great success, and as a general grass and clover mixture for dairy farms can be strongly recommended, because it is one for which the seed can be readily obtained, is not expensive, and possesses a sufficient number of distinct plants to permit of complete occupation of the land: Timothy ................ 8 pounds Red Glover. <5. eos a we a a 4 pounds PIS UIC Gs © 5 3ay-icsh nesev'eh Nae sab eae Sayan Pa? a SO EIS 2 pounds Cleaned red-top............. 2 pounds This mixture should be sown at the rate of twenty to thirty pounds per acre,—not less than twenty pounds on medium soil, and as much as twenty-four to thirty pounds or even more on very good soil. If seeded in the middle states any time from the middle of August to not later than Sep- tember 20, this mixture of grasses and clovers will make sufficient growth in fall to cover the ground completely, and prevent the starting of weeds, and under good climatic conditions will successfully survive the winter. ‘paysaarey U-aq pey yoy jo doso Furros v seqye porueyd ‘svedaoo-pue-w10Q "ZF “ST MIXED MEADOWS 201 Manures and fertilizers It has been shown by experiments that a liberal supply of plant-food from artificial sources is quite as serviceable in supplying the plants with their needs as a supply from natural manures, provided there is sufficient organic matter in the soil. If the cost of actual plant-food is taken into consideration, the increase in crop may be secured at a lower cost with the artificial than with the natural manures. A primary consideration is that the land shall be in good tilth, and the preparation and cultivation made as previously recommended; and there should be an occasional application of lime,—at least once in five years,—at the rate of twenty-five bushels per acre. This general prac- tice will greatly improve the soil in physical char- acter, and prevent to a large extent the compacting which would be likely to follow a continuous use of chemical fertilizers, without the direct addition of vegetable matter. Under these conditions the following recommendations as to fertilizers are made. In summer, while the land is being pre- pared, a few days previous to seeding, apply broadcast a fertilizer rich in minerals, as Ground bone... 2... eee ee es 150 pounds Acid phosphate. .......... . . 600 pounds Muriate of potash ......... . . 250 pounds This mixture should be applied broadcast at the rate of 300 to 500 pounds per acre; and at time of ‘902 FORAGE CROPS seeding a further application should be made of 300 pounds per acre of a commercial fertilizer, containing Nitrogen: 2 46-88 a wa ee ee 3 per cent Phosphoric acid (available). . .... . 6 per cent Potash. . 2... 6 ee ee ee wes © ~ 5 por cent This will ensure an abundance of the mineral elements, and sufficient nitrogen to supply the immediate needs of the plant and to encourage a vigorous growth in the fall. If the land is in good condition, and the plants winter well, a top-dress- ing on the first cutting is not usually required, although, in order to ensure a good second crop or aftermath, it is desirable that the top-dressing be made after the first crop is removed, preferably of the formula mentioned for seeding down, at the rate of 300 to 400 pounds per acre. The second season, the crop is likely to be made up largely of timothy and red-top, the clovers having disap- peared, and a top-dressing should then be made early in the spring, as soon as the grass has well started, of a fertilizer rich in available nitrogen, in order that the plant may have a nitrogenous -food that it can appropriate rapidly when it needs. Therefore, a mixture of Nitrate of soda... .. 2... 2. eee 500 pounds Ground bone... .. 1... 1... eee 200 pounds Acid phosphate... .......... 200 pounds Mouriate of potash .......... .100 pounds MIXED MEADOWS 203 may be applied broadcast at the rate of 200 to 300 pounds per acre. This will stimulate and strengthen any weak plants, and provide all plants with the nitrates, so essential at this season of the year. To ensure a large second crop of forage, imme- diately after the first crop is removed a further application of the top-dresser formula should be made, and at the same rate. It must be remem- bered that if a rapid and large growth of succulent food is to be secured, the plants must he abun- dantly supplied with all the essential constituent elements; and since the crop is one that does not have to be reseeded annually, a very considerable increase in the cost of the fertilizer may be allowed in lieu of the preparation and re-seeding that would be necessary if not abundantly fed and if weeds and foreign growths had encroached. While the amount of fertilizer recommended may seem large to the farmer accustomed to extensive practice, trials at a number of Experi- ment Stations, notably, Rhode Island (Bulletin No. 99, “A Six-Year Rotation of Crops”), and the experience of growers, notably George E. Clark, Higganum, Conn., show that if large yields of hay or forage (from four to six tons of the former per acre per year) are to be secured, this liberal use of fertilizers is desirable, for the profits are greater. The Rhode Island Experiment Station 204 FORAGE CROPS finds to be profitable an annual application of 1,050 pounds per acre of a mixture of Nitrate of soda .....-.. 222+ 350 pounds Muriate of potash... .... 2.2 ee 200 pounds Acid phosphate. ....- e+e sees 500 pounds Clark recommends, for seeding down, an annual application of 400 to 800 pounds per acre of a mixture of Ground bone ........+++6- 1,000 pounds Muriate of potash... 2... 2... es 800 pounds Nitrate of soda. .......... . 200 pounds and two top-dressings of 200 to 300 pounds each of an equal mixture of ground bone, muriate of potash and nitrate of soda. These larger applica- tions, however, assume a much more thorough preparation of land previous to seeding than is outlined here. Values of mixed forage crops A crop of mixed grasses and clovers is useful for green forage from about June 20 to July 10, according to the locality and season. It is one of the most palatable and useful of our forage crops, making a well-balanced ration in itself, and producing a relatively large yield of dry matter.

The second crop will range from four to six tons, depending on the season. If the clovers are abundant, the second crop will be richer in protein than the first cutting. The yield of digestible nutrients from an acre of this crop will compare fav- orably with that of any other crop of this class, and it will be well adapted to the purpose. Owing to the high content of dry matter in the various grasses, the usual quantity used,—fifty pounds per day,—will supply a larger portion of nutrients than is furnished by the same quantity of rye or wheat, and thus reduce the amounts of fine feeds required, a very important matter in most cases. For hay suitable for the dairy, these mixtures 208 FORAGE CROPS are very superior. Yields have been secured, under good conditions, ranging from three to four tons per acre from the first cutting, and frequently one ton and a half in the second cutting, making it also a very profitable crop from the standpoint of supply of nutrients. It is not recommended that fields that are intended to serve as hay should be pastured, although the pasture is of excellent quality. If made into hay for use on the farm, the crop should be cut before it matures, if the largest quantity of highly palatable and digestible dry matter is to be obtained. When the plants are in blossom, or immediately after,—if there is a large proportion of the grasses,— may be regarded as the best time to cut under average conditions. The plants harden rapidly after this period, increasing proportionately the indigestible woody fiber and decreasing the digestible protein. Timothy grown for market purposes may be cut at a later period, for market conditions demand _ well - matured, though not over-ripe hay, and increased yields are secured if cut. at this later period. CHAPTER XII ALFALFA Tue leguminous forage plants may be classed into three groups: perennials, biennials, annuals. Of the perennials, the plant most useful for for- age, and the one that occupies the relative posi- tion among the legumes that corn does among the cereals, is alfalfa, although it differs from corn in having a more restricted habitat or adaptability, not so readily conforming to a wide range of soils, climate or conditions of growth. It should be said, however, that alfalfa has not yet received the eareful attention that its merits warrant, and the chances are that a wider study of the plant will show that it is adapted to conditions which are not now thought to be satisfactory. The chief diffi- culty in the growing of the plant thus far, particu- larly in the eastern and middle western states, is in securing and maintaining a good “stand.” Alfalfa is not a new plant. It has been culti- vated in Europe. for nearly two thousand years, and is well known in both North and South America. It was introduced into California from Chili nearly fifty years ago, and its use has gradu- ally spread eastward. Long before this, however, N (209) 210 FORAGE CROPS it had been introduced into New York from Europe. It is now regarded as one of the most important forage-crop plants in those states where irrigation is practiced. About fifteen years ago, it was found that it could be successfully established in those states where there is shortage of rainfall, but where irrigation is not practiced, as, for ex- ample, in Kansas, in which state the area in alfalfa has rapidly increased and where it is now regarded as one of the most important forage crops. It has also been the subject of experiment in many of the eastern and middle states, notably New York, New Jersey and Maryland, and the results secured in recent years show that with proper care in the preparation of the land for seeding, and in subsequent management, it may be profitably grown. In many parts of the eastern states it is now an established forage crop. Once well established the plant will last a num- ber of years, from four to ten or more, depending on the character of the land, the treatment in ref- erence to manuring, methods of cutting, and free- dom from weeds and grass. The annual upright, branching stems do not sprout when cut, but die back to the crown, when new shoots start and grow rapidly. The roots extend much deeper than those of most plants, sometimes reaching a depth of twelve feet or more, under favorable conditions. For this reason alfalfa should not be grown per- LAND FOR ALFALFA 211 manently in orchards, as its deep roots are lable to injure those of the trees. It is often able to adapt itself, however, to soils in which the roots cannot extend very deep. Land, and its preparation Alfalfa grows well on varying kinds of land, providing the subsoil is open and porous. The most favorable land is a rich, somewhat sandy loam, warm and friable, with a deep and loose or gravelly subsoil, well supplied with lime. A dense clay or hardpan subsoil is most unfavorable. Al|- though rich land is preferable, alfalfa does well on poor, well-drained gravelly soils if well provided with the mineral elements, as phosphoric acid, potash and lime. While the plant requires much water, it will not flourish where the water-level is too near the surface, say nearer than eighteen inches, or when the ground is saturated, or where, when flooded, the water stands more than two or three days. Acid lands are uncongenial. The field intended for alfalfa should be treated the season preceding so as most effectually to subdue all weeds and cause the sprouting and destruction of any weed seed in the ground. Farm- yard manure should preferably not be used for at least one year before seeding, as it favors the growth of weeds, : 212 FORAGE CROPS Owing to the practically permanent character of alfalfa, it will well repay the expense of careful and thorough preparation of the land. This is very important in order to secure a good “stand.” -If the subsoil is hard and compact, the subsoil plow should be used. If a piece of sod land is to be converted into an alfalfa field, it should be plowed and planted with some cultivated crop the first year or two, in order to put the soil into good physical condition as well as to destroy all tufts of grasses which may spread, as grass is the worst enemy of alfalfa. It is desirable to have the soil somewhat compact for the seed, and therefore, it is better not to sow alfalfa on new-plowed ground. Plowing should be completed as long before sow- ing as possible, and the land should be rolled to compact it, and afterward lightly harrowed to leave the surface finely pulverized, and to prevent loss of moisture. Manures and fertilizers _ Alfalfa is a heavy feeder, and will not thrive on ‘lands deficient in plant-food. It is especially de- sirable that the soil contain abundance of lime, both in order to supply the needs of the plant and to correct any possible acidity, for, as already stated, acid soils are unfavorable for the growth and development of the organisms that are neces- ‘reah @ asv1OJ UI2IZ JO SU0} Usa}JeUIU SuIpjaA atov uv ‘kasdee MAN UL BIVI[Y ‘OF “BLY 214 FORAGE CROPS sary to enable the plant to gather the atmospheric soil ritrogen. The fertilizers should contain chiefly potash and phosphorie acid, and, although alfalfa is capable of obtaining atmospheric nitrogen, it responds quickly to applications of nitrogenous manures, particularly in its early growth. The lime and fertilizers should be spread broadcast and _ har- rowed in previous to seeding. The lime should be applied, when possible, to the preceding crop, in order to ensure its thorough distribution and in- corporation with the soil. The following applica- tions per acre are recommended in the East, even on good lands: First year, before seeding, thirty-five bushels of stone lime and a mixture containing 3 per cent ni- trogen, 10 per cent available phosphoric acid and 5 per cent potash, at the rate of 400 pounds per acre. When there is a known deficiency in mineral elements, as in sandy soils, these fertilizers may be reinforced with ground phosphate rock or bone, or kainit, and plowed in. In the fall or early winter a top-dressing with fine manure is good, if free from weed or grass seed. The latter point is important, as weeds will crowd out the alfalfa. The fertilizers should be applied just previous to seeding, and well worked into the surface. The manure should be applied late in the fall after cutting has ceased; it should be fine, and evenly FERTILIZING ALFALFA FIELDS 215 spread; it will prove serviceable both in protecting the plants and in furnishing plant-food that may be well distributed in the soil by fall and winter rains. Second and succeeding years, a top-dressing is recommended of eight to ten tons of manure, and an application of fertilizers supplying about twenty pounds of available phosphoric acid and twenty- five pounds of potash, which may preferably be obtained from 150 pounds of acid phosphate and fifty pounds of muriate of potash per acre. The fertilizers may be broadcasted, preferably after the first cutting in spring, or previous to the last cut- ting in fall, and the manure applied as recom- mended for the first year. In regions where alfalfa is new, the land should be inoculated. There is but one practical way to do this,—by the use of soil from an established alfalfa field, or from a patch of sweet clover (melilotus). The same bacteria inhabit each of these plants. It does not matter how much soil is used, so long as it is fine and is scattered over the field and harrowed in before sunlight destroys the germs. As little as 200 pounds will inoculate an acre, and a ton of earth has been used with good results. Even and thorough distribution of the inoculated soil is readily accomplished by sowing it on the land just after plowing, the tillage required in seeding ensuring the complete distribution. 216 FORAGE CROPS Seed and seeding Pure seed is essential,—only that which is bright, plump and clean. Dodder is a parasitic plant, that twines about the alfalfa and thrives on its juices. Dodder seed may come with alfalfa seed. The alfalfa seed ought always*‘to be re- cleaned to free it from this parasite. There is no remedy for dodder when once established in a field except to plow up the infested patch. Alfalfa seed resembles that of red clover, but is larger and, when fresh, has a greenish yellow color. It is sometimes recommended to sow clover with alfalfa; this is a doubtful practice as, when the clover disappears, it will leave an uneven and too thin stand of alfalfa, although it is good practice to seed a little alfalfa with clover and timothy, on land intended for alfalfa later. Experience has demonstrated that, in order to secure a good stand, it is best to sow thirty to thirty-five pounds of seed per acre. The seed should be sown broadcast, and covered by a very hght harrow or weeder, and lightly rolled. If seeded in spring, the last of April or the first of May is preferable in the northern states, and with- out any protecting or nurse-crop. In the North, notably in Wisconsin, alfalfa is seeded in spring, using a nurse-crop of oats or barley. The best nurse-crop is beardless spring SOWING ALFALFA 217 barley. This is not the heaviest-yielding barley, but it is the best nurse-crop yet found for alfalfa, because it usually does not lodge, does not stool very much, nor shade the land too much, and it comes off early in the season. The purpose of using a nurse-crop is to discourage the growth of fox-tail and other annual grasses until the alfalfa can get a start. It is very unsafe to sow alfalfa alone early in spring, because of the dan- ger of its being choked with grasses. One can get a much more satisfactory stand with the barley than when sown alone. A bushel to the acre will be enough barley, although more may be used. It is best to sow with a drill, sowing the alfalfa seed at the rate of about fifteen to twenty pounds per acre in front of the drill. The land should have been first deeply plowed, and early enough in the season, if possible, to let it settle together, then worked to a good seed-bed just before sowing. ‘The time of sowing should be as early as the danger of hard -freezing is past, say the middle of April for the 40th par- allel, earlier to the south, and later to the north. Oats as a nurse-crop are not nearly so safe as barley, yet they may be used.' No more than a bushel of seed should be sown to the acre. The oats must be eut for hay just when coming in bloom. If cutting ‘is postponed until grain is formed, half or more of the alfalfa will be killed. 218 FORAGE CROPS If the oats lodge, cut them for hay the next day. Oat hay is a good thing to have, if it is properly cured. When barley seed is not available, oats may be used with good results, if care is taken to mow on time. After the nurse-crop is cut away, let the alfalfa alone. It will start into growth promptly, and if the soil is fertile and well inoculated, the crop will make rapid growth for a time, usually for about fifty days. As long as it continues to grow thriftily, do not cut. If a rust appears, it should be clipped close, which will check or destroy the disease. Unless seeded, early alfalfa ordinarily will not make sufficient growth before midsummer to with- stand the weeds and drought. Where the winters are not too severe, the trouble with weeds may be avoided by seeding the last of August or alter danger of crab-grass is passed; when seeded at this season the weeds are not likely to take posses- sion during the fall and sufficient growth will be made to enable the plants to withstand the winter. The crop from late summer seeding should not be eut the first fall, even though a considerable stand is secured, but left as a protection in winter. There will be no danger of smothering, as the plants will usually stand erect rather than go down. Care should be taken that the seed is not put in too deep—this is very important and is often SOWING ALFALFA 219 the cause of failure. The depth may vary some- what with the kind of soil, but in general, if planted more than three inches deep, there is danger that the germinating plant will not be able to reach the surface. One-half to two inches are about the extremes. Another point of importance, as already stated, is that the soil should be packed around the seed. Many failures to secure a stand of alfalfa are trace- able to sowing the seed broadcast on new-plowed ground, and then to harrow, mixing the seed loosely with the surface soil, but not compacting it thereafter by means of a roller. Under favor- able conditions of soil and moisture the plant might survive, but it is safer to compact the soil and then go over it with a light harrow or weeder, loosening the immediate surface. Subsequent treatment The growth of weeds in spring seedings should be checked early by mowing, and as soon as the weeds are large enough to be clipped. By slightly raising the cutter-bar, the mowing machine can be used. If the crop of clippings is not too heavy, it may be left on the field and will serve as a mulch for the dry weather. This destruction of weeds in the early growth is very important, and frequent cutting is helpful, also, in establishing the young plants. ‘yoy, Adon puv |[vy Joos aay, “UOsvas eq} UL Fuiyzuo ysag sezeJLV Le Fla CUTTING THE ALFALFA 221 Before clipping, however, examine the little alfalfa plants to see whether buds have started near the ground. If these buds are just burst- ing into leaf, clip the alfalfa at once. Do not clip it before the buds start. Do not cut the alfalfa for hay or any other purpose before these buds have formed close to the earth. To cut it before the buds appear may very seriously set it back, and may possibly kill young alfalfa. To leave alfalfa uncut will also very seriously weaken it, and may result in its death. However, the first season it should be permitted to grow as long as it is vigorous. There should always be left a growth of at least a foot to protect the crowns in winter. Alfalfa should be cut when about one-quarter of the plants are in blossom, whether the growth is short or tall, unless a seed-crop is desired. If left until fully blossomed, the quality of the prod- uct is reduced; besides, the plants are injured and subsequent crops are smaller. On rich lands, two crops are sometimes secured the first summer from spring seeding, but on poor lands or in a dry season, no crop can be expected unti! the second year. Yield of alfalfa The yield on established fields will vary accord- ing to the eharacter of the land, thickness of 222 FORAGE CROPS stand and method of treatment. It ranges from ten to twenty-six tons per acre green forage for all cuttings, or an equivalent in dry hay of two to six or more tons. The larger yield is readily obtained on good lands. Alfalfa is a gross feeder, particularly on the mineral elements, and a large producer, and is sometimes considered as an exhausting crop. This is a mistaken idea; it should rather be looked on as acrop fulfilling the proper aim of rational agri- culture, which is most perfectly to transform into products the raw materials at disposal in atmos- phere and soil. The chemical composition of alfalfa The following table shows the composition of five different cuttings from established fields at the New Jersey Experiment Station farm, as well as the composition of the hay when ready to put in the barn to be fed. These analyses, which are representative, show the variations in the compo- sition of the different cuttings in the green state, all samples representing the crop cut when first blos- soms appeared or just before blossoming, as well as the changes that were caused by handling, curing and storing. The composition of the different cuts will vary with the time of cutting and character of season.

The composition of the dry matter, however, shows the true differences. The first and fifth cuttings show a much higher per- centage of protein and ash, indicating a higher feeding value and that they were not so fully ma- tured as the others, although the different cuttings 2294. FORAGE CROPS were made when the crop had apparently reached the same stage of growth.

There was a loss of moisture and a change in relative composition of the hay in curing, although the changes were not serious, and were rather evenly distributed throughout the various groups of nutrients; whereas the losses incurred in storing were considerable, aside from the moisture, and were particularly noticeable in COMPOSITION OF ALFALFA 295 the loss of protein, which resulted in a considerable relative gain in the amount of fiber. This storage loss was to be expected, as the chief losses were probably mechanical, due to the shattering of the leaves, which are richer in protein and poorer in fiber than the stems. The chief point of interest is the very large quantity of dry matter obtained in the year’s growth, nearly six tons, and the large proportion of nitrogenous substance, or crude pro- tein, contained in it (2,327.7 pounds) equivalent to that in about 7.5 tons of wheat bran. Variations will occur in samples from different fields and in different years, but it is thought that the analyses given here fairly represent what may be expected as to variations in the composition of the different cuttings, and the losses that occur in handling when made and stored as hay. Alfalfa as a soiling crop Alfalfa is one of the most useful of the soiling crops, because it is ready for use early in the year, and because three to four cuttings may be had each year. In the East, the first cutting is ready about the latter part of May or first of June, the second, usually within a month or five weeks, and the third and fourth usually four to six weeks after cutting the preceding crop. It possesses more nearly than any other crop the very great oO 226 FORAGE CROPS advantage of furnishing a practically continuous supply of forage during the growing season. That this may be accomplished, it is necessary that a large part of the crop shall be cut either too early or too late; therefore it is desirable to have other forage crops if the very best results are to be reached. Care should be exercised when using it for soiling, particularly in the early cuttings, as animals are very fond of it and are likely to eat so much as to cause bloating. Animals have been soiled, with success, at the New Jersey Experi- ment Station for the past eight years, and notrouble has been eneountered, probably due to the fact that the animals, previous to feeding on alfalfa, have been supplied with other succulent forage, and the quantities have been adjusted so that there should not be an excess for any one animal. In the early cuttings, from thirty-five to forty pounds per day usually are fed, gradually increasing to fifty pounds on the third day after beginning. After once started in this way, there is no danger, and only favorable results are likely to follow. Another peculiar advantage of the soiling for- age is its richness in digestible protein; fifty pounds of the green forage will furnish very nearly two pounds of digestible protein. Therefore, the feeds used with alfalfa should contain more car- bohydrates than are usually fed with forage. A mixture of feeds that would make a good ration New Jersey. Ready for soiling May 27. First cutting of alfalfa. g. 48. Fig 228 FORAGE CROPS with fifty pounds of alfalfa per day may consist of about six pounds per day of a mixture of three pounds each of wheat bran, dried brewers’ grains and corn meal. When large quantities of alfalfa are available as forage, the quantity used per day may be increased, thus reducing the necessity for feeds; and such feeds as are used may be richer in carbohydrates, as, for example, corn meal. Alfalfa as a hay crop When desired for hay, alfalfa should be cut when budded, or just before full bloom, as it con- tains more nutriment at this time; besides, it is better for the subsequent crops to cut the plant before it is in full bloom. The value of the hay depends much on the method or care used in curing it. Alfalfa cannot be cured as hay is usually handled. After cut- ting, it should be allowed to lie in the swath only long enough to become well wilted, when it should be raked into windrows, where it may be left a few hours before putting into cocks. The hay should be allowed to remain in the cocks until practically cured, which usually requires two or three days. Then it may be thrown out, dried with three or four hours’ sun, and hauled to the barn without further handling. It is desirable to use hay caps in unfavorable weather, as water ALFALFA HAY 229 penetrates alfalfa cocks very readily, which injures the feeding value and causes mechanical losses. In good weather, alfalfa that is cut in the morning may be raked in the afternoon of the same day. It should not be left long enough to become dry and brittle, or many of the leaves will shatter in raking, much reducing the value of the hay. In experiments at the New Jersey Experiment Station, it was shown that alfalfa hay may be substituted for the protein feeds generally used, without interfering with the health of the ani- mals, and at considerable saving in the cost of the ration, although the yield of milk was not quite so high. In other experiments, when cow- pea silage and alfalfa hay were used as the source of roughage as well as for the protein, and corn meal used to supply the carbohydrates, the yield of milk was greater and the cost per quart much lower than from the regular barn ration, in which the source of protein was such feed products as dried brewers’ grains and wheat bran. In other words, it has been demonstrated that it is quite possible, with the judicious use of such leguminous crops as alfalfa and cowpeas, to produce all the needed nutrients on the farm, thus saving expensive feed bills and at the same time enriching the soil in nitrogen. It is impor- tant that dairy farmers should grow, if possible, a few acres of alfalfa to supply part of the green 230 FORAGH OROPS forage needed for summer feeding, and as much as possible of the protein needed to balance the silage or ‘other fodder rations of the winter. Alfalfa as pasture Alfalfa may also be safely used as pasture for horses and swine, and the careful farmer who gives the subject intelligent personal attention may also pasture cattle and sheep on alfalfa with suecess. There is always danger, however, of losing animals with bloat, and pasturing, especially with sheep, is injurious to the alfalfa because they eat away the young buds, which would soon develop into new branches. The younger plants are not strong enough to withstand long-continued pasturing the first year after sowing, and much tramping is injurious at any time. Alfalfa silage Alfalfa can be successfully made into silage, although, in common with other plants of a highly nitrogenous character, it is not so desir- able as corn. The losses are likely to be con- siderable, and the product seems to be less pala- table than corn silage. Nevertheless, there are many circumstances when its preservation and use as silage are to be recommended. CHAPTER XIII THE CLOVERS THE true clovers all belong to the genus or group Trifolium, of which there are many spe- cies and varieties in many parts of the world. The sweet or Bokhara clover is a Melilotus, not sufficiently grown to warrant discussion in a brief popular book like this. The bur clover is a Medicago, allied to alfalfa. Other related plants of the legume family are sometimes known as clover, but they need not be described here. There are four types of true clover that must be discussed in any American book on forage plants: (1) red clover (Trifolium pratense), and mammoth red clover (variety perenne, formerly but improperly called Trifolium medium); (2) alsike clover (JZ. hybridwm); (3) crimson clover (T. incarnatum); (4) white clover (7. repens). All these clovers are natives of the Old World. THE RED CLOVERS It has been well said that red clover is more valuable among fodder plants than wheat is among cereals. As a forage crop, it has no (231) 232 FORAGE CROPS superior, all things considered. Like corn, it is adapted to a wide variety of soils, and, because of its habit of growth, is always beneficial when introduced into a rotation, aside from its par- ticular value as a forage crop. While its best use for most purposes is in connection with other clovers and grasses, it is excellent as a green forage plant, since it is very palatable and contains the nutrients in such proportions as to make it a well-balanced ration in itself, thus serving to supplement pastures, as well as to provide an excellent dry forage. While it may persist for three years, in prac- tice it must be regarded as a biennial, the length of life depending largely on its treatment and the nature of the soil. It thrives best on deep loamy lands, rich in humus, where, as a rule, it stands longer than on light lands, although it is well adapted to them and large crops are obtained when well fertilized. Soils and manures Stiff clays, when properly tilled, are suitable for red clover, although they should be well drained to avoid any standing water. Dry, sandy or hot lands are unfavorable, although they may be very materially improved by liming or by the use of marl. On loose lands and heavy clays, COMMON RED CLOVER 233 clover is lable to be uprooted by the alternate freezing and thawing, and on sandy lands it suf- fers from drought. Like alfalfa, the soil must be either rich in lime, or this substance must be applied, for it is a heavy feeder on lime, as well as on the other mineral constituents. The very beneficial effects that were observed from the former use of gypsum, when it was thought that plaster or gypsum was a specific fertilizer for clover in the eastern states, is now considered to be due to the power that gypsum possesses of setting free the dormant potash of the soil. Therefore, on old soils from which the potash has been to some extent exhausted, the element potas- sium should be applied in considerable excess. The very beneficial effect of wood ashes, following the use of gypsum, also verifies this conclusion, as ashes is rich in both of the constituents, potash and lime. As clover is a legume, it is not usually bene- fited by the addition of nitrogenous manures, except in the early stages of growth. On soils not well supplied with vegetable matter, manures are very beneficial, primarily in correcting the deficiencies, and in providing a more favorable medium for the development of the specific bac- teria. The size of the crop will be measured to some extent, also, by the abundance of mineral elements, thus enabling the plant to employ to 234 FORAGE CROPS full advantage its capability of gathering nitro- gen. In many cases, particularly on soils that are likely to heave, a mulch of manure is very advantageous as a protection. Methods of seeding red clover The method of seeding most generally prac- ticed is to sow in March or April, on wheat or rye (which was seeded the fall previous), when the ground is still moist, and danger of very heavy freezing is past. By this practice, the light freezing and subsequent drying of the soil causes the seed to be covered, and it will then germi- nate and make a light growth previous to har- vesting. It is also seeded in spring with oats or barley; this is a common practice in regions which are cool and moist, as in many of the western states. The quantity of seed ranges from eight to twelve pounds per acre. The plants grow rather feebly until the grain is removed, when they usually come forward rapidly, sometimes permit- ting a fall cutting, but in any case they make a erop the following year. Recently, however,—especially where the plant is grown primarily for forage purposes,—the seed- ing is made in the latter part of August or early September, without nurse-crop, usually following SHEDING RED CLOVER 259 potatoes or some other hoed crop. When seeded in this way, the land should be very carefully prepared, and the surface made as fine as pos- sible, in order that germination may be rapid and complete, as well as to provide abundant food near the surface. The quantity of seed in this case is about six- teen pounds per acre on the average. On poor lands, more seed must be used. If seeding is too thick, the plants are lable to lodge and thus be badly injured for either forage or hay. When seeded in this way, the seed should be lightly cov- ered, preferably with a weeder, and on light lands rolled with a light roller. In ordinary seasons, the plants will make considerable growth and become well rooted before winter, and the crop usually will be ready to harvest as early in the next season as in the second year if seeded in the old way with grain. In many sections, red clover is used as a catch-crop in corn, mainly to serve as a spring pasture and in preparation of the land for wheat. This practice is generally not suitable when the primary purpose is to make soiling crops or hay. In the eastern and central western states, the crop will be ready to harvest about the middle of June, although the time will vary, depending on the season; if dry and warm the crop will mature earlier than if cold and wet. 936 FORAGE CROPS Harvest, yields and value If used primarily for soiling, harvest should begin when the plant is fully in head, and it may contimue until many of the heads become brown. This period will range from ten days to two weeks, depending on the soil and season. As a soiling crop, red clover should be fed with care at first, unless the animals have been accustomed to green forage of other kinds, as they are extremely fond of it, and there is danger that there will be a tendency to bloat. When they have been regularly fed on green for- age, and the quantity is regulated, no danger need be apprehended from this source, and the usual amount of fifty to sixty pounds per day may be used. With a good stand and sufficient moisture, the yields of red clover will range from six to ten tons per acre. It usually pays to allow it to stand for the second crop, which is also quite as serviceable for forage as the first, although the yield is smaller, —four to six tons per acre. The second cutting is usually ready in early August. Red clover varies in its composition according to the time of harvesting, although either when eut young, or allowed practically to mature, it is much richer in the nitrogenous compounds than are the grasses, but not so rich as alfalfa.

Clover hay is one of the best kinds for dairy purposes. However, it is liable to considerable loss in harvesting, unless great care is used, owing to the rapidity with which the leaves dry and to their tendency to fall in curing and housing. If cut when about one-third of the bloom has disappeared, it will contain very much less moisture than when cut earlier, and _ still retain a large proportion of leaves if carefully handled. Clover should be cut when free from dew or other moisture, and allowed to wilt, then raked into windrows, and put up into cocks and cured in this way, rather than be allowed to lie in the 238 FORAGE CROPS swath until dry. Light rains, or even heavy dews, will change the green leaves to dark brown, and make them crisp and readily removed by handling; they will also extract the aroma arising from the essential oils, which is so important in making the hay palatable and attractive. When properly cured, the hay will have about the composition noted above, and, as a roughage to use with silage in winter feeding, it cannot be surpassed except perhaps by alfalfa. The high content of protein makes clover one of the best plants for forage purposes. It is possible with clover alone to supply all the needed nutrients in good proportions for dairy animals. It is usually better, however, to feed from fifty to sixty pounds and to supply the remainder of the nutrients from other sources, to give variety to the ration. -Pasturing red clover When the purpose is to secure the best yield of forage, it is not desirable to pasture red clover, although it is an excellent pasture plant, and is well liked by all farm stock. The tramping of animals will soon kill many of the stools, injur- ing the stand, and causing a smaller yield in later cuttings. Red clover is an important constituent of permanent pastures, generally insuring a larger yield the first season than grass alone. PERENNIAL RED CLOVER 239 Mammoth red clover This resembles the common red clover, but is larger, later and more truly perennial. It is a great forager. The stems are stout and coarse, and, therefore, it is not so desirable for hay; but these characteristics do not impair it as a soiling crop. The preparation of soil and the seeding inay be similar to the practice recommended for common red clover. The quantity of seed should be twelve to fifteen pounds per acre, according to the character of soil. When seeded in the fall, the crops should be ready for the first cutting by June 15. Yields are usually heavier than those of the common red clover. A good average yield is ten tons of forage per acre. Mammoth clover may be fed as recommended for red clover, the composition not materially dif- fering, although, unless the plant has reached the full blossom stage, it is likely to carry less dry matter; therefore, a slightly larger proportion should be fed. All animals are fond of this for- age, and the results of feeding are exceedingly satisfactory. If the land is good, and well drained, the crop will make a rapid second growth, to serve for for- age, or for pasture, it being excellent for grazing. The great foraging powers of this plant make it exceedingly valuable as a soil-enricher. The 240 FORAGE CROPS large amounts of mineral matter from the lower layers of soil, being stored in the roots and stems, will greatly improve the soil for subsequent crops. ALSIKE CLOVER Alsike clover is more perennial than red clover, and can be left frequently for three to five years. It is little affected by extreme seasons, and lands on which other varieties do not grow may produce an abundant harvest. It thrives on damp, moist loams and clays, on lands too wet for other clovers. It is very hardy, and not liable to be uprooted by late frosts, which frequently injure the red clover. Alsike clover has a rather superficial root system; therefore, the preparation of land should be very thorough, and the surface layers well enriched, particularly with the mineral elements. Owing to its somewhat creeping habit, it is not well adapted to seeding alone; as the stems lie along the ground, without rooting, the remainder of the stem ascending, in wet seasons it is liable to lodge badly, and the lower stems to rot. Seeding alsike clover Alsike may be seeded with wheat or rye, in the same way as red clover. When used for forage, the best time for seeding is in late ALSIKE CLOVER 241 summer or early fall. The quantity of seed will be about one-half that recommended for red clover, as the seeds are about half as large. A pure sowing of alsike, however, is not usually advisable, because of the tendency to lodge, as already pointed out; although, where it grows well, it may be used in a soiling-crop rotation with great advantage. Value and yield Mixtures of red and alsike clovers and timothy make a most excellent forage, the timothy sup- porting the clover and preventing lodging. The alsike will mature about a week later than the red clover. It makes a very rapid and usually a large second growth. The best time for cut- ting is when the plant is in flower, as at this period it is richest in digestible nutritive matter. It contains more water, as a rule, than red clover, thus causing the same tonnage weight to carry less nutriment. The yield will range from eight to twelve tons per acre, depending on the charac- ter of the soil. The composition of this clover is similar to that of red clover. Alsike hay and pasture Alsike clover makes very palatable and useful hay, its fineness of stem and large proportion of P 249, FORAGE CROPS leaf giving a larger percentage of digestible matter than the red clover at the same period of growth. However, it is more difficult to cure, and suffers great loss in handling if care is not exercised. It also makes excellent pasture, starting quickly after the first cutting, and being less readily destroyed by the tramping of animals than red clovers.

Because of its adaptabilities, it has quickly made a place for itself in American agricultural practice. Its habits of growth are not so well known as those of the other kinds described, and for this reason, among others, is not so generally distributed, even in those sections in which it thrives. Its habits are such as to make it undesirable to substitute for rod clover, although it may well supplement it. CRIMSON CLOVER 943 It is essentially a cool-weather plant, thriving well in late fall and early spring, and maturing seed in the middle states about June 1. These characteristics make it especially suitable for a Fig. 49. Field of crimson clover, grown as a catch-crop seeded in corn at last cultivation, 244 FORAGE CROPS catch-crop or cover-crop, to be used without interference with regular rotations. It has proved to be hardy in the eastern and middle states, although many failures are reported, which are probably due in large part to failure to under- stand its peculiar habits. The impression that it will grow well on poor soils with other crops, under all conditions of season and climate and without particular care in seeding, is very erro- neous. It must have abundant food; it is affected by drought and cold and severe weather; it can not subsist with other crops which rob it of mois- ture and plant-food; it must be carefully seeded in order to insure against adverse conditions, although when conditions are favorable it will catch and grow from a mere scattering of the seed on raw ground. Method of seeding Crimson clover should preferably be seeded at: the rate of twelve to fifteen pounds per acre, on a well-prepared seed-bed, and covered lightly with harrow or weeder. It is not suited for spring seed- ing, as it ceases to grow as soon as hot weather comes. The best period for seeding ranges in the eastern and middle states from July 15 to Septem- ber 1. Therefore, it may be used as a catch-crop, seeded in corn, after the regular cultivation has CRIMSON CLOVER 245 ceased, and also after early potatoes, tomatoes and other crops harvested early enough in the season to enable its roots to get hold of the soil and to make considerable top before cold weather. While it requires good land for its best develop- ment, it is well adapted to light sandy lands if well supplied with mineral food. It will grow later in the fall than red clover, because it is not injured by light freezing, and it also makes more rapid spring growth than any of the other clovers when seeded in the late summer. When land is light and poor, a dressing of acid phosphate, say at the rate of 150 pounds per acre, will aid in securing a catch and insuring a crop. Crimson clover as green forage Early maturity is one of the most valuable char- acteristics of crimson clover, from the standpoint of its use as green forage, making it particularly useful in rotations. In the middle states it will begin to head about May 15, thus following directly after wheat. Cutting should begin as soon as the heads begin to form, and may be continued until the plant is completely headed out. This period ranges from ten days to two weeks. The dry matter is richer in protein than red clover; and the plant has more moisture at the same stage of growth than the red. Therefore, larger quantities, 246 FORAGE CROPS as usually cut, will be required to furnish the same amount of total nutritive matter. Crimson clover is an exceedingly palatable for- age, and serves good purpose for soiling, for hay, or for pasturage. The composition at different periods of growth is shown in the following tabu- lation: CoMPOSITION OF CRIMSON CLOVER May 12, May 24, May 31, Pounds per hundred of before blossoming in blossom mature Water ca. ea 6 ea x 89.17 84.23 83.26 Dry matter. ...... 10.83 15.77 16.74 Crude fat. ....... 0.43 0.53 0.53 Crude fiber... .... 1.78 4.37 4.78 Crude ash ....... 1.21 1.31 1.47 Crude protein ..... 2.53 3.00 2.95 Nitrogen-free extract .. 4,90 6.57 7.01 Albuminoid protein . . . 1.80 2.09 2.13 The samples taken on May 12, before bloom- ing, show a high content of water. The samples representing full bloom, on May 24, and the fully matured plant, on May 31, show a much higher content of dry matter, although still much less than is contained in other green forage crops. The samples at this time also show a much higher percentage of crude fiber than on the earlier dates. In the earlier stages of growth, crimson clover is too watery to give the best satisfaction as an exclusive feed, although in actual practice the for- age would be much drier than is indicated by the analyses. CRIMSON CLOVER 247 “There has been much discussion at farmers’ institutes and in the columns of the agricultural press,” write Roberts and Clinton (Cornell Bulletin No. 135), “as to the value of crimson clover in this state [central New York] as a forage crop and as an improver of the soil. To answer these questions in part and to determine the relative value of the Ke Fig. 50. Crimson clover ready for soiling, May 20. New Jersey. 948 FORAGE CROPS different clovers, there were planted side by side on August 1, 1896, three plats of clover, one of crim- son, one of common red and one of mammoth. The soil was gravelly and porous. All varieties of clover came up quickly and made good growth. The crimson clover, however, made far more rapid growth in the fall than did the others. One object of these experiments was to determine the amount of nitrogen stored up by the different varieties of clover. On November 2, samples were taken of each kind of clover, the roots and tops of each being taken as the sample. The chemical analysis shows the following amount of nitrogen stored up in each per acre: Nitrogen Nitrogen Total pounds Kind of clover in tops in roots of nitrogen (pounds) (pounds) per acre Crimson ...... 125.28 30.66 155.94 Red 4: 2% ee w 63.11 40.25 103.36 Mammoth ..... 67.57 78.39 145.96 * All clovers wintered well, but in the spring the freezing and thawing killed nearly all of the crim- son clover. It had, however, served its purpose as a cover-crop and for late fall pasture would have been valuable, leaving in the ground enough fertilizing material to pay for the expense of the seeding.” Yield of crimson clover The yield varies widely, but from good seeding the average of green forage should be about eight CRIMSON CLOVER 249 tons per acre. In experiments at the New Jersey Experiment Station, crimson clover was _ the cheapest forage crop grown. This was due both to the low cost of seed aud to the fact that it was grown without extra expense of manure or ferti- lizer; besides, it was generally grown as a catch- crop and did not interfere with regular rotations. Its advantages as a soil-improver are also worthy of careful consideration by the dairy farmer. If seeded in corn at the last cultivation, it may be harvested in time to permit of planting corn the next season, and besides forage, the humus-form- ing material remaining in stubble and roots improves the land.

The stems are finer and are readily eaten and digested. The diffi- culty in making hay arises from the fact that it is ready for hay-making at a period when the season is still cool, and bright sunshiny days are less frequent. Stock is said sometimes to suffer from eating crimson clover hay from the forma- tion of hair-balls in the stomach, due to the hairs on the plant. Crimson clover as pasture Crimson clover is very highly regarded as a pasture plant, particularly for late fall and early spring. When seeding has been made in July, on lands not otherwise occupied, it makes rapid growth and serves as late fall pasture, not being injured by frost in the same degree that red clover is. Fall pasturing frequently benefits the plant, as a thick, heavy crop is not so liable to be carried safely through winter. It makes earlier pastures than any other clover. It is very useful for sheep or cattle. As a pasture clover, it is a very desirable plant in the rotation, inasmuch as it is adaptable, easily grown, matures quickly in a cool season and possesses the characteristics of other clovers in contributing directly to the in- erease of nitrogen in the soil. WHITE CLOVER AS FORAGE 25] WHITE CLOVER White clover is not suitable for soiling forage or hay, but is very useful in the formation of pas- tures, especially on low-lying lands. On good land it lasts from four to five years. It is superior to red clover in thriving on lands of inferior quality, standing pasturing well, and possessing higher nutritive value. Sometimes the creeping stems and foliage become too luxuriant, when it may act injuriously in suppressing other rina: White clover is less sensitive to climate than red clover. It bears drought very well, although its roots confine themselves mainly to the superficial layer of the soil. In dry seasons the old branches do not lengthen, and growth is confined almost entirely to the principal stem. White clover suc- ceeds best in a moist soil, containing lime and an abundance of humus. It can also adapt itself to sandy soils, which are not too loose and dry, pro- viding the surface contains sufficient nutriment. The parent stem sends out creeping branches; ‘these in turn branch and at intervals give off shoots. If conditions are favorable, the branches become long and extend in all directions; in this way a large surface is soon covered. If the plant has not been sown with a cereal crop, full development is made the first year, flowering early in spring, but rather later than red 252 FORAGE CROPS clover. As pasture it is better than any other kind of clover, being readily eaten by all kinds of live-stock. Pasturing is begun in the spring, as soon as. animals can get a good bite, and it remains good until late autumn. Because of its higher content of water, white clover is more difficult to cure than red clover, but not so wasteful in curing, as the leaves do not fall away so readily. When seeded alone, ten pounds of seed per acre should be used. But a pure sowing of white clover is neither so good nor so healthful for stock as a mixture. It may be mixed with other clovers and with grasses, either for temporary or perma- nent meadows. It is much benefited by top-dress- ings of lime, marl, ashes or mixtures of bone and potash. CHAPTER XIV OTHER LEGUMINOUS FORAGE CROPS Muc# attention has been given to leguminous forage crops in recent years because of their soil- enriching propensities and their supply of pro- tein substances to animals. Many of these plants are now being experimented with in different parts of the country; some of the remaining kinds that have now thoroughly proved themselves may be discussed here. COWPEA The cowpea is an annual viny plant, more a bean than a pea. Its origin is authoritatively stated to be in the Orient, where it has been cul- tivated for thousands of years; it is thought to have been introduced into this country in the early part of the eighteenth century. Its best development occurs in warm climates; in this country it has found a congenial home in the southern states, where it reaches its maximum development. A number of varieties have been developed, however, that: are adapted to cooler conditions, so that now it is well distributed even in parts of the North, where its adaptation to (253) 254 FORAGE CROPS various uses and the rapid and large development of plant make it one of the most useful of the annual summer legumes for forage purposes. Varieties of cowpea The natural tendency of the plant toward varia- tion has resulted in many varieties, although the permanent and distinct kinds are comparatively few. The same variety is likely to be given a new name in different parts of the country, as, for example, the one variety that goes under the name of Unknown, Wonderful and Quadroon. In addition to the confusion arising from this practice, the same name is frequently given to a number of varieties, as, for example, the name Crowder, which is applied to any variety in which the seeds are closely packed or crowded in the pod. The further fact that season and climate exert such an influence on the plant as to make a variety in one place very different from what it is in another place, renders it difficult to give positive advice as to the choice of kinds for specific purposes. The varieties range from a bush a foot or so high, without runners, to those having distinct vining or trailing habits, the vines sometimes reaching a length of ten to twenty feet. The pods range from four to eighteen inches in length, giving seed of every possible i MB Fig. 51. The cowpea, 956 FORAGE CROPS shape and form. The period of mature growth also varies, the varieties ranging in time of maturity from two to six months, although the habit of plant bears some relation to the period, for the more nearly the plant approaches the bush form, the shorter the time required for maturity. In order to choose the proper variety, the object of its cultivation should be clearly established. When short, quick growth and maturity are re- quired, then the bush varieties should be chosen, particularly in the North; whereas, if the purpose is to produce much forage and the period of growth can be extended, the vining varieties are likely to be more useful. When grown primarily for green forage, the period in which they must grow should determine the variety. It is more difficult to choose varieties for the North than for the South, as the plant has not been so carefully studied in this sec- tion. In the more northern sections, the Early Black, Small Black, Black Eye, Mt. Olive, South- down, Red Ripper, Whippoorwill, Wonderful, Clay, New Era, and Iron have proved excellent for the various purposes for which cowpeas are grown. Early Black, Black Eye, New Era and Mt. Olive are superior when the seed crop is desired, as they mature quickly; the others are better adapted for forage and green manure. The cowpea varies so widely in its habits of growth that it is possible to select varieties suitable to all conditions. THE COWPHA 257 Time and method of seeding The time for seeding the cowpea depends on the weather. The crop should not be sown until danger of frost is past, and the soil is thoroughly warm. In cold, backward springs many failures have been recorded because of too early seeding; the seed is then liable to rot, and if uniform and quick germination does take place, the crop is re- tarded and is likely to be unsatisfactory even if warm weather follows. This is particularly true when cowpeas are grown for green forage or hay. Neither should they be sown for forage later than two months before the average date of frost, as the first heavy frost will destroy the plants and no variety that is now known will reach a satisfactory stage of growth within this period except as green- manure. For forage and green manure, the crop may be sown broadcast at the rate of one to one and one- half bushels per acre, or it may be drilled in with an ordinary grain-drill. If the seeding is not made too early, broadcasting is very satisfactory. If early growth is retarded, weeds get a foothold, and the crop is likely to be choked out. When the crop is grown for seed, planting should prefer- ably be in drills, from two to three feet apart, or a little closer than corn, and the quantity of seed may be reduced to three pecks per acre. When Q 258 FORAGE CROPS the seed is expensive, it pays even for forage to use the smaller quantity and cultivate, rather than to broadcast the larger quantity. Seed should be covered one to two inches deep, and on very light soils a little deeper. The season, to some extent, governs the depth; in a dry sea- son, the deeper the seed the better. The difficulty in too late summer broadcast seeding is that crab-grass or other growth is likely to choke out the plants. Value of the cowpea crop Perhaps there is no other annual leguminous for- age crop that is so generally useful as the cowpea. In the first place, it grows in hot weather, when it is desirable to have the ground covered; (2) its long tap-root penetrates the subsoil, loosening it and making it more porous; (3) the absorption and assimilation of the free nitrogen makes it of great service; (4) it provides good forage; (5) it may be used as a cover-crop; (6) the roots and stubble are left as additions to the soil, always causing considerable improvement. Manures and fertilizers While the cowpea is well adapted to light soils, nevertheless, if the best results are to be had, the soil must be well supplied with phosphoric acid Cowpeas planted in rows and cultivated. Fig. 52. Fig. 53, Crop of cowpeas for soiling. THE COWPEA 261 and potash. On lands that are capable of produc- ing fair crops, the fertilizers may be limited to an application of these minerals, and a mixture of Acid phosphate ............ 300 pounds Muriate of potash... ........ 100 pounds applied at the rate of 200 pounds per acre is recommended. This should be broadcasted, and well cultivated into the soil previous to planting. Harvesting cowpeas For soiling purposes the crop may be harvested in its immature state, although a larger amount of dry matter will be secured if it is not cut until the pods are turning yellow. It is often necessary to have the crop ready in two to two and one-half months; when the early varieties are sown, and the season is favorable, profitable crops may be harvested as early as this after seeding. If the cowpea is not harvested promptly it does not suffer serious loss, as is the case with many other crops. The leaves remain green and the stems succulent until growth ceases. When the entire season can be used for the crop, the trailing varieties will give the larger yield, although they are more difficult to harvest, owing to the intertwining of the vines. If cut in a very immature stage, the forage shows a higher content of water, and the dry matter is 262 FORAGE CROPS relatively richer in nitrogenous substance than when more nearly mature. Cowpea hay is more difficult to cure than clover, owing to the very succulent stems and large leaves. Therefore, it must be handled carefully, in order to prevent losses in the field, or molding in the mow. In the southern states, the practice of “ricking” is quite general. That is, the crop is mown, allowed to wilt in the swath, then raked into windrows and allowed to dry until it can be readily handled, then carted and placed in rather large stacks on ricks that are placed a foot or so from the ground, enabling the plants to cure thoroughly. There is no special need for this extra labor in the northern states, providing it is cut as early as September, as it will cure readily in the windrow if the weather is good. Yield and composition of cowpeas The yield of forage under the various condi- tions of soil, season and time of harvesting, will naturally vary widely, ranging from four to twelve tons per acre, with a probable average of eight tons on good soils. The yield of dry matter and actual nutrients increase as the plant approaches maturity. On the average, the green forage will contain about 16 per cent of dry matter.

It makes excel- lent pasture, and, if the animals are not allowed to feed it too closely in the beginning, it will furnish good grazing for six to eight weeks, as the tendency of the plant is to throw out new runners when the main stems are removed. Pas- turing is wasteful, however, as the animals tramp much of the herbage into the earth, besides kill- ing some of the plants. It is better practice to make the crop into hay, as it makes a very pala- table and highly digestible product, and one which, because of its high content of protein, can be used to substitute for concentrated feeds. The cowpea is one of the most useful forms of winter forage, as it can be fed in considerable quantity, and because it possesses characteristics which make it a good substitute for purchased protein feeds. Experiments at the New Jersey, 264 FORAGE CROPS Tennessee and Alabama Stations show that cow- pea hay can be very profitably substituted in part for concentrated feeds for dairy animals, although it was shown to be advisable to use a little feed in the ration. SOYBEANS The soybean is from Japan, where it is one of the staple crops. It is now generally grown in the southern coast and middle states. Soybeans are also grown successfully in Illinois, Michigan and Wisconsin, being better adapted to the climatic conditions of those states than cowpeas. The soy- bean has a strong central root, stiff stems, broad leaves, and somewhat resembles the ordinary bean, although it is larger and bushier in form. The plants may be dwarf and early maturing, or late and tall, but in no ease do they have the vining and trailing characteristics of cowpeas. They are strictly upright plants. There are a number of varieties. The Green seems to be the variety most gener lly used. Seeding, growth and use The plant resembles the cowpea in many of its characteristics; namely, that it should not be seeded until the soil is warm, and when grown THE SOYBEAN 265 for forage it should preferably be planted in rows in order that it may be tilled, although it may be seeded broadcast. The quantity of seed per acre varies from one to one and one-quarter bushels broadcast, depending on how well the seeds are covered. When seeded in rows, the quantity may be reduced to one-half bushel or three pecks per acre. The land should be put in good condition, and fertilized as advised for cowpeas, that the germination may be prompt. For forage purposes it does not possess charac- teristics very different from those mentioned for cowpeas. Experience thus far shows that the soy- bean is slightly more difficult to handle, and that the yields are not so heavy, but the plant contains more nitrogen in the dry matter than the cowpea. It has been grown for forage when there has been a scarcity of cowpea seed, and many prefer it to the cowpea because it is easier to harvest. Its period of growth is about the same as for cowpeas, reaching its best condition in two and one-half to ‘three months. The stems are stiff and hard, and the entire plant is not so palatable as the cow- pea, although, owing to the abundance of large leaves, the feeding value is quite as high as that of the cowpea; in fact, at the stage of growth best for forage, it is richer in dry matter and protein than the cowpea. Yields of forage on good soils average lower than the cowpea,—about 266 FORAGE CROPS seven tons per acre. The average composition is as follows: One ton AN, average contains furnishes Per cent Lbs.

The crop is well worthy of wider use. VELVET BEAN The velvet bean has attracted much attention lately in the southern states. In Florida it has been one of the most useful of the forage plants. It grows well on light, sandy land, and the yield is ordinarily larger than that of the cowpea. Under favorable conditions the vines reach a length of twenty to thirty feet. The season of growth is much longer, and for that reason the seed cannot be matured except in the most south- ern states. Experiments in the middle and east- ern states show that it is not well adapted to those sections, and does not make as satisfactory crop for any purpose as the cowpea. It is used as a green-manure and cover-crop in the South. o b =) bb a sg o EB o Ss = fe} oH o 2 ° os] q 3 n 3 o ng Lo] qa s n 2 ao f=} u o & a oe 3 o s o o n n 3 o a EB fo} o ow ° 3 = o eo i) a ite} op oa & “TAZ TAaJ ANOAIIM ‘svadmoo s9jJe oAY ‘CoG ‘ALT CWI Fe VETCH FOR FORAGE 269 VETCHES There are two species of vetch that have re- cently come into considerable use. In the use of vetches for any of the purposes mentioned, care should be used to prevent the plant from ripening and re-seeding the land. In some states, notably Michigan, vetch has become a nuisance as a weed, and is said to have made profitable wheat-growing impossible in certain sections. Since it is not pos- sible to separate the vetch readily from wheat, the latter is ruined for milling purposes. When grown only for green forage purposes, the danger is not formidable. Spring vetch The spring vetch or tare (Vicia satwa) may be substituted for Canada field peas, in a mix- ture with oats; and in the northern states, where the pea-louse has been very destructive, it serves an excellent purpose. It is sown in spring or early summer, and does not survive the winter. The preparation of soil should be practi- cally the same as that recommended for oats and peas. Fertilizers should also be of the same char- acter. Experiments indicate that one bushel of seed, with one to one and one-half bushels of oats per acre makes a good mixture, although the smal- ler quantity of oats will be better on good land, as 270 FORAGE CROPS too large seeding of oats prevents a large growth of the vetch. The plant is trailing in habit. If conditions are favorable, it will make a very much thicker growth than the Canada field pea, and pro- vide excellent forage, being very palatable and highly digestible when in the best stage for feed- ing. It requires a longer period for maturing, and this extends the time during which the forage may be used,—a very important advantage, par- ticularly in dry seasons. The composition of the oat-and-vetch forage does not differ greatly from that of the oats-and- peas. The crop may also be made into hay of an excellent quality, and it is readily cured. Hairy or winter vetch The sand, winter or hairy vetch (Vicia villosa) is another species that thrives on poor soils, and is useful as an early spring forage, withstanding the winter and growing in spring. Owing to its trailing habit, it should not be seeded alone (except as a green-manure or cover-crop), but with rye or wheat, preferably wheat for the cen- tral states, in August or September. It is desir- able to have the soil well prepared in order to encourage an early and rapid fall growth, as well as to ensure a large crop in spring. It should be seeded at the rate of about one-half to one bushel HAIRY VETCH 271 per acre, with the wheat or rye, the former being sown at the rate of one bushel per acre and the latter at the rate of three-fourths of a bushel per acre. It will be one of the first crops ready for use in spring, as it matures with the cereal. The chief advantage of the use of hairy vetch with rye or wheat lies in the fact that a larger crop of forage may be secured than when the cereal is grown alone. The chief disadvantage of this crop is the expensiveness of the seed, but this difficulty will doubtless be overcome as soon as the value of the crop is known and larger areas are grown. Owing to its very early growth it may be pastured to advantage when not convenient, to use as a soiling crop, usually coming earlier than ordinary pastures are ready. Of course the quan- tity of forage will be less when used as pasture than when cut and carried to the barn. It is not so desirable for hay as the spring vetch, because good hay weather does not usually prevail. COMPOSITION OF HAIRY VETCH An average contains gereeld Per cent Lbs.

It is a stiff, erect-growing plant, wholly unlike the common bean in appearance. It grows two to four feet high. It produces large pods and big usually flat or flattish seeds. It is more like the pea than the bean in its relation to climate, as it withstands some frost. It has been cultivated from prehistoric times and its nativity is in doubt. It is much grown in Europe, primarily for forage purposes, although the seed may be used, both full grown and immature, for human food. It demands a cool climate and a long growing season and does not do well under the hot, dry summers of the United States. It is grown successfully in parts of Canada, where it has been used somewhat with corn and sunflower to make silage; this combination is known as the “Robertson mixture.” This mixture does not seem to have made much headway. Frequently the plants are grown to full maturity and a meal made from the bean. Planting may be made early in spring in clay loams. The seed is sown in rows, twenty to twenty-eight inches apart, so as to allow for BROAD BHAN 273 cultivation, which is especially important with this crop for conserving the moisture. Cultiva- tion is discontinued in the latter part of July. If the crop is in early enough, it will stand up well under the snow when used as a winter cover- crop, but will winter-kill. Seeding is done at the rate of six to eight pecks per acre. A good yield of beans is thirty bushels per acre. JAPAN CLOVER Japan clover (Lespedeza striata) is a native of Japan and China, introduced intq the southern part of the United States about 1840, since which time it has spread throughout the southern states, where it has proved of great value as pasture, although it is frequently used also for hay when grown on good land. Japan clover is also a valu- able cover-crop and green-manure crop, as it is well adapted to light aud poor lands and withstands drought well, growing and spreading when other plants die for lack of moisture. The plant thrives as far west as Kansas, and as far north as Mary- land, although it does best from Virginia south- ward, where it has spread naturally. Under ordinary conditions of growth, it does not reach a height of more than ten to twelve inches, and on very poor land it simply spreads over the ground. Until recently, it was allowed to seed naturally, or R 974 FORAGE CROPS was seeded alone, especially on the poorer lands, the custom being simply to harrow the land and broadeast about twelve pounds of seed per acre, without covering. The seed should not be sown until all danger of freezing is past, as the young plants are tender and will be destroyed by a light frost. Where its advantages as a forage plant are appreciated, it is now often made a part of a mix- ture with grass, and four to five pounds of seed are used per acre. On good land and well cared for, Japan clover will reach a height of two feet or more, and can be readily used.for soiling or for hay. It is ready for use about the middle of June as far north as Virginia, and earlier in the more southern states, and makes good pasture as late as November. As with white clover, it should be kept pastured closely for best results, and when so managed is relished by all grazing stock. When grown for hay, the common practice is not to cut until some of the seeds on the lower part of the plant are ripe, which permits it to reseed. While more easily cured than the red clover, it should be handled in practically the same way in order to prevent losses of leaves, which are richer in protein than the stems. As a soil reno- vator alone, it is well worthy greater attention than is now given it, though valuable, also, as pasture, hay and seed crop. CHAPTER XV ROOT-CROPS ENGLISH agriculture is noted for its root-crops. These crops become a regular part of rotation systems. They thrive in the cool moist seasons of that country. In America they have not re- ceived the attention that they deserve, particu- larly in the northern states and Canada, although in the latter country they are better appreciated than in the United States. They afford good nutrient materials in most wholesome and diges- tible forms, and because of their succulence they become a good adjunct to dry and concentrated feeds. “The reason why the production of roots is of special interest in the north Atlantic states,” as expressed in a recent Cornell bulletin (Root-crops for Stock-feeding, Bulletin 243), is “that these states raise a comparatively large amount of roughage and a small amount of concentrates, while the north central states raise a large amount of cereals or concentrates in proportion to hay and forage, as shown in the following table of the ratio of concentrates to roughage in the north. (275) 276 FORAGE CROPS Atlantic and north central states, according to the census of 1900: North North Atlantic Central All cereals except wheat, million tons .. 4.4 69.2 All hay and forage, million tons. .... 15.6 49.0 Per cent of cereals, except wheat ... . 22.0 58.5 Tons cereals except wheat, per animal unit 55 1.55 Tons hay and forage, per animal unit .. 1.95 1,10 Total tons of food per animal unit (of about 1,000 lbs. live weight)... 2.50 2.65 “The significance of this table is further em- phasized when the superior feeding value of concentrates is fully understood. For example, experiments made by Zuntz, of Germany, show that when clover hay was fed to horses, forty-one pounds were digested out of each hundred pounds of hay fed, while, when oats were fed, sixty-two pounds were digested, or 50 per cent more. It was found, however, that it required the energy of twenty-four pounds of the forty-one pounds of hay digested to chew and digest the hay, leaving the net nutritive value at seventeen pounds. On the other hand, it required only twelve pounds of the sixty-two pounds of oats to masticate and digest the oats, leaving fifty pounds of oats available for producing energy or work. In other words, the oats had three times the value of the clover hay for the production of work in horses. The energy used up in chewing and digesting SIGNIFICANCE OF ROOT-CROPPING 277 food is manifested in heat and helps to keep the animal warm, and is therefore not entirely lost when the ration is merely for maintenance. But since, in any liberal feeding for the production of work, the production of meat, or of milk, the amount of heat thus produced is sufficient to keep the animal warm, the figures given above may be taken as representing their true food value. “One of the objections to roots as a food prod- uct lies in the fact of their high water content. This limits the amount which may be fed and be- comes of special importance where they are fed in connection with silage. On account of this high water content it will not be practicable to feed a sufficient amount entirely to take the place of the cereals, even should this be desirable for other reasons. The trend of experimental evidence is that the feeding value of the different types and varieties of root-crops depends more largely on the percentage of dry matter than on any other factor; for example, the percentage of dry matter appar- ently modifies their feeding value more largely than the percentage of sugar. “The problem in New York state is whether we ean afford to raise roots, and, if so, what kind. The following table shows the minimum average and maximum number of pounds of dry matter per acre which was obtained at the Cornell Experi- 978 FORAGE CROPS ment Station in 1904, 1905 and 1906 from sowings made during May: Minimum Average Maximum Mangels ...... 2,168 5,155 8,453 Half-sugar mangels . 5,480 5,880 6,440 Sugar-beets .... 6,014 7,090 8,090 Rutabagas ..... 3,537 4,331 5,079 Hybrid turnips . . . 2,584 3,694 5,111 Common turnips .. 1,710 2,680 8,500 Kohlrabi ...... 8,570 4,070 4,540 Cabbages. ..... 4,076 4,662 5,588 Carrots... 1... 1,878 3,134 4,379 Parsnips ...... 2,080 3,130 3,680 “The estimated yield of grain from flint corn, the same seasons, at this station, was approxi- mately 2,000 pounds; while the yield of dry mat- ter in silage from dent corn was about 4,000 pounds. It is probable that the season of 1904 was relatively favorable to the production of roots as compared to Indian corn, but this was not true of 1905 and 1906. During the latter years the aver- age yields from roots were better than in 1904, although the Jand used was conceded by all inter- ested to be less favorable than that used in 1904. “The present high price of cereals is a factor in favor of the production of root-crops. If corn meal continues to be worth twenty dollars a ton, or more, in New York state, economy in the pro- duction of roots would be indicated, while, if the price should fall to ten dollars a ton, corn meal would probably be the cheaper source of concen- MANGEL-WURZELS 279 trates. The serious handicap to the raising of root- crops is the fact that, with present cultural meth- ods, a large amount of hand-labor is required. The point of view that it is desired here to empha- size is that, while roots may not be economically raised as a substitute for silage or other coarse fodders, it may be economical to raise them in New York state as a partial substitute for concen- trates, particularly the cereal grains.” MANGELS Perhaps there is no other one crop that has had so wide use as succulent winter forage as mangels, although they have had less popularity since the general introduction of the silo. It is a crop that can be grown to advantage, however, and it possesses many characteristics that make it an extremely valuable product, even when silage is also used. Varieties of mangels There are many varieties differing but slightly, as, for example, the Golden Tankard, Mammoth Long Red, Red Globe and Yellow Globe, any of which will answer for forage purposes. Cornell experiments! give the following indica- 1Culture and Varieties of Roots for Stock-feeding, Bulletin 244. 280 FORAGE CROPS tions of varieties: ‘Among the mangels, all of the long varieties seem to be able to produce good yields but have various defects. The Globe and Tankard varieties usually contain a higher per- centage of water and are low in dry matter content. Two half-sugar mangels, Vilmorin Half- sugar Rosy and Carter Half-sugar, are recom- mended as suitable stock to use for breeding American strains. Sugar-beets, although rich in dry matter, are generally so much more expensive to harvest that the writers are not prepared to advocate their extensive use for stock-feeding.” Land, manures and fertilizers In the culture of this crop, particular pains should be taken to provide a deep surface soil, as the deeper the soil the greater will be the proportion of root grown under the ground. Be- sides, the crop requires a large area of soil, in order to supply the rather exorbitant demands for plant-food. When the best yields are ob- tained, it is frequently recommended to subsoil at least eighteen inches, in order that the fine rootlets may penetrate to lower depths. In order to ensure a large yield, the crop should be well supplied with all the constituents of plant-food in available forms. When the land is heavy, it should preferably be plowed deep in the fall, and MANGELS 281 covered with manure at the rate of eight to ten tons per acre. This should be worked into the soil early in the spring, and the whole surface thoroughly cultivated, and fertilizers applied con- taining a high content of nitrogen. A good formula should earry nitrogen, 4 per cent; phos- phorie acid (available), 10 per cent; potash, 6 per cent. If manure is used as recommended, a dress- ing of 400 pounds per acre of this fertilizer at time of seeding may be made with advantage, even on good soils. Seeding and handling The quantity of seed is five to eight pounds per acre. The seed does not germinate quickly, and early growth is slow and, as a consequence, early cultivation is not possible, because the rows cannot be readily followed; therefore weeds take posses- sion and make hand-labor necessary. It has been suggested that a little buckwheat be added to the seed; this plant germinates quickly, and the broad leaves clearly mark the row, making earlier cultivation possible. Mangels should be sown in rows two to two and one-half feet apart in May or early June, and, after well started, the plants should be thinned to eight to ten inches apart in the row. The cultiva- tion should be frequent, and, early in the season, relatively deep, in order that the soil may be in 989 FORA@GH CROPS the very best condition for absorbing and retaining moisture, as well as to remove all weeds. The beets should be harvested as soon as frost occurs. In order to preserve them for winter, they may be stored in the field by placing in cov- ered heaps from five to seven feet high, although the better plan is to remove after thoroughly dry to a root-cellar in which they are not liable to freeze and the temperature is not too high. Composition and use of mangels As with all root-crops, the content of dry matter is relatively low, usually not more than 8 to 10 per eent. The nutrients are highly digestible, how- ever, and when associated with so large an amount of water they possess a very high value, particu- larly in furnishing food in a wholesome form. They are extremely palatable, and when otherwise only dry feeds would be used, they answer a good purpose in keeping animals in condition, as well as stimulating the milk flow and the laying on of fat. They are very useful for cows, hogs, chickens and practically for all other kinds of farm stock. Because of their adaptability, the use of mangels is increasing in many parts of the country, espe- cially on small farms where but few animals are kept and where the labor is performed by members of the family.

In these trials no silage was fed, the basal ration in each case consisting of six and one-half pounds of hay and ten pounds of straw per cow. The experiment was so conducted as to eliminate, apparently, the factor of succu- lence, as shown by the following table of average of six experiments including about 150 cows dur- ing several months.

FORAGE CROPS “Tt will be noted that all the cows were fed roots, but two lots were fed roots containing seven and one-half pounds of dry matter, equal to about sixty-five pounds of fresh roots, instead of four and one-half pounds of dry matter, equal to about forty pounds of fresh roots. The additional three pounds of dry matter in the first-mentioned cases gave as good results as an equal amount of cereal grains, the cereals consisting either of Indian corn or of a mixture of barley, oats and rye. Roots, like the cereals, are highly digestible, perhaps even more digestible than the cereal grains, and herein probably lies their high value. From the stand- point of the results which they produce, the roots may be looked on as watered concentrates. They have, apparently, a high net available energy.” Yield of mangels per acre When conditions are favorable, the tonnage yield is very much greater than can be secured from corn or other forage crops, frequently reach- ing as high as twenty-five to thirty tons per aere, although the total dry matter is much less than for a smaller tonnage of corn, cowpeas, or other suc- culent forage, and the labor involved is relatively greater per unit of dry matter. The greater ex- pense of the mangel crop is due in large part to the extra cost of cultivation. MANGELS AS FORAGE 285 Mangels versus corn The relative production of dry matter in a crop of fodder corn and in mangels is well shown by an experiment made by the New Jersey Station in 1894. The soil was good, and the plots on which the crops were grown similar in character. The tonnage yield and yield of nutrients per acre were as follows: Containing pounds of Mangels cee Petes Hoe tetas Weight of green crop. . 56,600 20,000 36,600 Seah Dry matter . .... 4,684 6,130 os. 1,446 Crude fat ....... 33.9 152.2 eae 118.3 Crude fiber ...... 379.2 1,484.7 ae 1,105.5 Crude protein ..... 684.9 468.9 216.0 eee Crudeash ....... 503.7 243.8 259.9 fw Carbohydrates ..... 3,112.6 3,780.2 a8 667.6 The first point of importance shown by this comparison is that the total dry matter contained in the crop of mangels was nearly 25 per cent less than in the fodder corn; and for every pound of dry matter contained in the crop it was necessary to handle twelve pounds of water, while in the corn fodder the proportion of dry matter to water was as 1 to 3.2. It is shown, also, that in feed constituents the corn fodder furnished nearly five times as much crude fat, and four times as much crude fiber as the mangels and 20 per cent more carbohydrates. The feed constituent furnished in greatest amount by the mangels is crude pro- 286 FORAGE OROPS tein, of which more than 50 per cent was shown by analysis to exist in the form of amides, com- pounds less valuable than true albuminoids. It must be remembered, however, that man- gels possess a value in addition to the actual food constituents contained in them, due to suc- culence and physical character, which it is im- possible to measure in definite terms, particularly for winter feeding in connection with dry fod- ders. Under certain circumstances their produc- tion is desirable, even though the cost of dry matter exceeds that in corn or clover, mainly be- cause of their dietetic effect and of the greater digestibility of the dry matter. SUGAR - BEET Sugar-beets are often recommended in place of mangels, largely because they contain a much higher percentage of dry matter, consist- ing largely of sugar. Varieties highly recom- mended by seedsmen are Queen of Denmark, White Rose Top and White Green Top, although those ordinarily grown for sugar are quite as useful. The preparation of land and fertilization should be practically the same as for the man- gels. The seeding should be somewhat different, as at least twenty pounds of seed is required per acre. Cultivation and harvesting and _ storing SUGAR-BEETS 287 may be practically the same as recommended for manegels. Yields range from ten to twenty-five tons per acre. They contain on the average 18 per cent of dry matter, thus getting in one ton nearly twice as much nutriment as is contained in two tons of mangels. They may be fed with dry foods at the rate of fifty to sixty pounds per cow. They are a good source of carbohydrates, aside from the dietetic value that they possess in quite as great degree as mangels. When only a few animals are kept, or when conditions of growth are most favorable and labor abundant, the growing of either sugar-beets or mangels is recommended as a source of succulent winter forage.

As for other root-crops, 288 FORAGE CROPS the soil should be deep and well fertilized, as it is impossible to grow a good crop on poor soil. The main varieties for stock-feeding are Long Orange, Long White and Short White. These may be planted from the middle of May to the middle of June, at the rate of about one and one-half pounds of seed per acre, in rows eighteen inches to two feet apart. The early culture re- quires considerable care, as the growth is slow, which usually makes it necessary to hoe between the rows. They should be thinned to about six to eight inches in the row. Carrots are useful chiefly as an appetizer, and are not fed in large quantities. They should be harvested before freezing weather, and stored in a dry, cool place. TURNIP AND RUTABAGA Turnips may be used as a ecatch-crop late in the season, and they are useful both for late fall and for winter feeding. They are particularly useful for sheep, and also, if carefully used, for dairy cows. They are very watery, and do not contribute a large amount of actual nutriment. They stimulate milk flow, and their action in this respect is responsible in large degree for the belief that they possess superior nutrient qualities. The varieties mainly grown for feeding are the TURNIPS 289 Purple-top and Yellow Globe. The Cow Horn is highly recommended as a catch-crop, because it roots more deeply, thus bringing to the surface plant-food from lower layers. As a catch-crop, turnips may be sown after potatoes, tomatoes or other early crop, or seeded in corn at the last cultivation, serving both to con- serve plant-food and provide a succulent feed. The yield varies widely. When grown primarily for forage and the soil liberally fertilized, as high as thirty tons per acre are recorded. The turnip does not seem to be able to obtain the necessary phosphates so readily as some other crops; there- fore it is especially benefited by applications of superphosphates. Lands in good condition in other respects may grow a maximum crop of turnips with additions of phosphate alone, applied at the rate of 250 pounds per acre of acid phos- phate. Under average conditions, however, an application of nitrogen and potash should accom- pany the phosphate. Turnips may be sown either broadcast or in drills; when seeded as catch-crops the broadcast method is practiced and seed used at the rate of two to three pounds per acre. Where grown for forage, they should be in drills, seeded at the rate of one pound per acre, and thinned to six inches in the row, and cultivated as other crops. The feeding of turnips to dairy cows, should be S 290 FORAGE CROPS made after the milking, as they are likely to add distasteful flavors if fed at other times.

Potatoes contain about 28 per cent of dry mat- ter, are very succulent and palatable, and exercise a very marked effect on milk production. They may be fed raw or steamed; if raw, they should be cut, to avoid danger from choking. They should be fed, at first, in small quantities, although the amount may be gradually increased to forty to sixty pounds per day. They should be washed and thoroughly cleansed before feeding. Potatoes should always be mixed with dry feed, the amount added being in proportion to the needs of the POTATOES 291 animal, and the potatoes not in such excess as to cause the animals to scour, which frequently occurs if too large quantities are used. SWEET POTATO Sweet potatoes are also an excellent food for cattle and hogs. In wet seasons, and on heavy soils, the crop is liable to be “rooty,” that is, the potatoes are not merchantable, although of good size. These imperfect roots may be fed in the same way as the white potato, although they usu- ally contain a little more dry matter and need not be fed in such large quantities. In the absence of other succulent feed they contribute very materi- ally to the improvement of the ration. CHAPTER XVI THE CABBAGE TRIBE SEVERAL members of the mustard family (Cru- cifere) of the cabbage kind are useful forage plants, and their cultivation seems to be increas- ing. In general feeding practice they may be compared with root-crops. In fact, kohlrabi is often classed with root- crops, and well it may be, since it is very closely allied to the turnips and rutabagas, differing chiefly in having the thickened part above ground rather than below ground. The leading cabbage-like forage plants are rape, cab- bage and kohlrabi. The kales are not much grown for forage in North America. Their culture does not differ greatly from that of rape. Thousand- headed kale is the kind mostly reeommended, but it does not appear to have any advantage over rape for forage. RAPE As a forage plant rape is a recent introduction into the United States. Several varieties have long been grown in Europe and other countries for forage purposes. Of the various kinds, but two are generally grown,—Dwarf (Dwarf Essex) (292) GROWING OF RAPE 293 and Giant. The former is more generally useful, especially on the light, chalky lands of England, and it is the only one that has given satisfaction in this country. The other is grown on strong lands, and occupies a full place in the rotation. Rape has taken the place of turnips to some extent, and is very similar in its management. All varieties are annual, but in England they sometimes do not mature seeds the first season. The advantages of rape are: (1) it is well adapted to most soils; (2) it can be seeded either in spring or summer, serving an excellent purpose as a eatch-crop and for green-forage; (3) the expense of seed and seeding is low; (4) it is especially useful for sheep and swine, although with care it may be profitably fed to dairy cattle. Preparation of land, and seeding The seed of rape is small, and the preparation of land is therefore very important. The land should be deeply plowed, covering all vegetable matter, thoroughly pulverized, and the surface soil made extremely fine previous to seeding. Although rape does well on soils of medium fertility, the best results are secured when they are naturally rich, or have been well fertilized. When grown for forage, an application of barn- yard manure at the rate of eight tons per acre, 294. FORAGE CROPS well worked into the surface soil, is desirable, as the plant is a voracious feeder. For its best growth it must have abundance of available nitro- gen. Hence, if manures are not readily obtainable, an application of fertilizers rich in nitrogen should be applied. Experience has shown that a fertilizer containing Nitrogen. j..é6 6s ee we ww ee 5 per cent Phosphorie acid (available) ....... 8 per cent Potash se #4 2) Se ae we He Se ws 9 per cent applied at the rate of 600 pounds per acre, will supply the food in good proportions. Should the season be unfavorable for rapid growth, an addi- tional application of 100 pounds per acre of nitrate of soda when plants have well started will stimu- late growth and help to ensure a large crop. This top-dressing of nitrate should be made when the plants are dry. The rape may be seeded either in drills or broadeast any time from early in May for pastur- ing in July or August, or as late as July or August for late summer and fall pasture and also for cover-crops. When used for a cover-crop, the broadcast method is probably the better. When a large yield of succulent forage is desired, it is better to plant in drills two to two and one-half feet apart, as this permits early and thorough cul- tivation. The quantity of seed to be used is to be determined by the condition of soil and weather. SEEDING OF RAPE 295 The quantity should be increased in dry weather and on poor lands. When sown broadeast, three to five pounds per acre will be sufficient, and when sown in drills from one to two pounds is recom- mended. For soiling purposes, it should prefera- bly be seeded in drills and about the time that corn is seeded, or when time of severe freezing is past. Machinery adapted for planting small seeds ean be successfully used for this purpose. Tillage should begin as soon as the plants are well started, and repeated as frequently as possible until the plants have arrived at such stage of growth as will not permit of further cultivation without injury. Ordinary cultivators will answer for the work, but one that will cut close to the line of the row, without covering the plants, is the best, especially in the earlier stages of growth. As with corn, the first cultivation should be deep and gradually become shallow as the roots take possession of the soil. Feeding value of rape crop The value of rape as forage is chiefly as a soiling crop or for pasture; that is, it cannot be harvested and preserved with advantage. When used as a soiling crop, it may be cut with a mower and placed in heaps, which will remain good for two or three days. The following description of 996 FORAGH OROPS rape as a pasture for sheep is in Farmers’ Bulletin No. 11, of the United States Department of Agriculture: “Rape is unrivaled as a pasture for sheep in autumn in those parts of this continent where it can be successfully grown. As a fattening food in the field it is without a rival in point of cheapness or effectiveness. The sheep that pasture upon it do the harvesting in a most effective manner, and with but little cost to the owner; and the manure made from it is distributed over the field which produced the crop, and in a form which is readily available for the plants of the succeeding crops. While rape thus grown and fed does not add fer- tility to the soil, unless in the plant-food it brings up from the subsoil, it does not detract from the fertility when the sheep which eat it off are in- closed upon it. When rape can be successfully grown as a pasture, the necessity for sending sheep and lambs to the market in a lean condition will be removed, and the numbers that may yet be fattened upon it in this country will only be limited probably by the inclination of the farmers and the demands of the market. Four to five millions of acres of arable land would suffice to grow rape enough to fatten all the sheep at present in the United States. “The manner of feeding off the rape when pas- tured by sheep and lambs is in outline as follows: THE FEEDING OF RAPH 297 "They should be tagged before being turned in upon the rape, or soon after, as they are liable to become purged to some extent at the first. They should not be turned in upon the rape when hungry at any time, as they: may so gorge themselves that bloating, followed by death, may ensue. When they have access to an old grass pasture at the same time, the grass eaten by them is usually very effective in preventing scours and other disorders arising from impaired digestion. When the ani- mals are once turned in upon the rape it is not necessary to remove them, unless in time of severe and prolonged storms of rain or sleet. At such times they may be given the protection of sheds when these are available, otherwise the shelter of a grove may prove of some service. After they have fed upon rape from two to two and a half months they will be ready for market. When it is desired to carry on the lambs into the winter months after the season for pasturing is over, they will go on improving in fine form where the man- agement is judicious. In other words, pasturing on rape is an excellent preparation for winter feeding. “The sheep or lambs should be visited two or three times a day by the shepherd. This may be done on foot when the flocks are small, but when feeding over large areas the aid of a saddle horse should be called in. When sheep get fat and 298 FPORAGH CROPS heavy they are somewhat liable to roll over on the back and so perish. They do not require any water when feeding upon rape, but should have access to salt at will. “There is no limit to the numbers that may be put upon one field except its capacity to sustain them. The labor of hurdling does not seem neces- sary, as the sheep waste very little of the rape. When it has grown strong and rank, they feed around the borders. Like an invading army of crawling insects, they make clean work as_ they go, but when the crop is light and thin tney feed in any portion of it.” Rape is also good forage for cattle, although, when fed to dairy cows, it is liable to contribute undesirable flavors to milk and its products, even though fed after milking, as recommended for turnips or other members of this family of plants. In experiments at the Wisconsin Agricultural Experiment Station (Bulletin No. 115) to deter- mine the quality of cheese as affected by the feed- ing of rape and other forage plants, it was found that whenever the rape was fed before milking, there was, in most cases, a very pronounced rape flavor; when fed just after milking, there was also a very noticeable flavor. In no case was the amount fed larger than ten pounds per day, al- though it was all consumed between the morning and night milking. In fairness to the rape, it is RAPHE FOR FEEDING AND COVER 299 stated that other green crops, as cabbage, corn and clover, also unfavorably influenced the flavor of cheese. To avoid danger of over-eating when pastured, cattle should be allowed to feed in the rape for a short time at first, gradually extending the period until they may be left with reasonable safety. When fed as asoiling crop, this danger is avoided, as the quantity given is entirely under the control of the feeder. In feeding sheep or lambs on rape, they should preferably receive in addition a small ration of oats in the morning, although in many cases they may be fed exclusively on this plant. As a cover-crop Rape also possesses great advantages as a cover-crop, as it may be sown thickly as late as August for late fall pasture, and that which has not been used as forage will serve as cover in winter, preventing blowing and washing of the soil, and maintaining much better condition of soil in spring than if the land is left bare. It is de- stroyed by the cold in the northern and central states, and for this reason is not so advantageous as winter leguminous crops for this purpose. Nevertheless, because it can be seeded later and makes a large fall growth, it possesses very superior advantages as a cover-crop. 300 FORAGE OROPS Yield and composition of rape Owing to the fact that rape is usually fed from the field, data in reference to yields are somewhat limited. At the Wisconsin and New Jersey Sta- tions, the yields have ranged, in round numbers, from twenty-three to twenty-seven tons per acre. When mature, rape contains more dry matter than most root-crops, as, for example, mangels and turnips and the total yield of nutrients is much greater. The average composition and yield of nutrients per acre are as follows: Oneton Average acre- contains yield furnishes Per cent Lbs. Lbs.

That cabbage possesses a very distinct value as a succulent forage crop is well understood by those who grow the crop for the markets and use the refuse for feeding. The extra cost of grow- ing cabbage beyond that of growing turnips, rape or other similar plants has probably been the cause of a lack of attention to it. The disadvantages of cabbage as compared with the other better-known crops mentioned, are (1) the expense of planting; (2) the large plant-food requirements; (3) the difficulty of storing for winter use; (4) the low percentage of dry matter contained in the crop. Farmers with small areas for growing forage will find cabbage a useful green crop, as it is excellent feed for all farm animals, and it is a fairly well balanced ration for milch cows. The crop is adapted to a wide range of condi- tions, although its best growth may be obtained in cool, moist climates, as are found in the more northern states and in Canada, or in certain re- gions along the shore, as on Long Island, where the atmospheric conditions seem to be- peculiarly favorable. The crop may be planted in a rotation, taking the place of oats in a rotation of corn, oats, 302 FORAGE CROPS wheat and grass, as it is a good preparatory crop for wheat. Preparation of land for cabbage, and seeding As with rape, the land should be deeply plowed and thoroughly cultivated, the surface well com- pacted and made fine, in order that the plants may not suffer for lack of food as soon as set. If seed is used in the field, the germination should be prompt and the early growth rapid. Farmyard manures are excellent, and, as the cabbage is a gross feeder, applications of ten tons or more per acre should be made even on good soils, and this dressing supplemented with nitrate of soda. The fertilizers recommended for rape, both in kind and quantity, will answer for cabbage. Attempts should not be made to grow cabbage unless there is an abundance of available food. As a rule, cabbage is not grown from seed planted directly in the field, and it is doubtful whether its successful and profitable use as a forage crop will warrant the extra labor required in transplanting. Of course, more seed should be used when the seed is planted directly in the rows, thus permitting the removal of extra plants when they have reached such size as to determine their vitality. The seed, in this case, may be sown with the ordinary grain drill. The rows should be about two and one-half to three feet SEEDING OF CABBAGE 303 apart, and the plants thinned to about two feet apart in the row. The wider rows are preferable, because of the greater ease of using machinery. The depth at which the seed should be planted is preferably from one to two inches, according to the nature of the soil.

From one to two pounds of seed per acre will be sufficient. The time of seeding will depend on the place it is given in the rotation. The young plants are tender, and should not in any case be planted in spring until all danger of freezing is past, although light frosts will do no injury. It is better to sow either early or late, since, if the cabbage is not seeded until late in the spring, the heads will not form so well, but, if sown very late, the plants will be hindered from making heads before cold weather sets in. In recent experiments at the Cornell University Experiment Station (Bulletin No. 242), the fol- lowing statements in reference to soil and seeding are made: “The soil considered best adapted is one rich in organie matter. Good crops can be raised on almost all types of soil, provided they contain the above requisite, are in good physical condition and contain an adequate although not excessive supply of water. Cabbages differ from almost any otber farm crop in that their successful production is little influenced by the type of soil on which they are grown, or, in other words, they show a wide range of adaptability, so far as this factor is con- cerned. Undoubtedly, this power of adaptability CABBAGE 305 to varying soils was an important factor in leading the primitive people of northern and_ central Europe to cultivate the cabbage, and, having been grown by the common people of these regions under all sorts of conditions of soil and climate, with more or less success, from prehistoric times until the present, this power of adaptability has been preserved. “The soil should be loose, friable and well pre- pared, deep fall-plowing being advised. An ap- Fig. 57. Solid (at the left) and loose heads of cabbage. plication of ten to twenty tons of manure per acre may be made before plowing. In spring, after harrowing, an application of well-slaked lime, at the rate of 1,000 pounds of quick-lime per acre, may be made, and harrowed in. The harrowing should be done before rain falls, otherwise the lime cannot be so readily incorporated with the soil. The advantages of lime for cabbage are recognized by many growers, and one of its benefits is its action TE 306 FORAGE CROPS in destroying the fungus that causes clubroot. After the lime is harrowed in or before liming, it may be advisable to apply part of the fertilizers. Amounts frequently used are 400 to 800 pounds of acid phosphate, 15 to 16 per cent available, or its equivalent, i. e., 60 to 120 pounds of phos- phorie acid; 100 to 150 pounds of muriate of potash, and fifty pounds of nitrate of soda per acre. Manure, lime and fertilizers should be uni- formly applied. This important matter should not be neglected. If the seed is sown where the plants are to grow, the last harrowing should be done with the Meeker harrow or some tool which will fit the surface equally well.” The bulletin also gives the yields of varieties for 1904, 1905 and 1906, and states that the fol- lowing are essentials of a high yield: “First, rotation. It matters little what crops be grown, provided they are in accordance with rational practice, the main point being that when cabbage crops follow each other in succession the soil is likely to become infested with the elubroot fungus, which will render it unfit for growing cab- bage for a number of years. Second, early plant- ing. This gives time for full growth and develop- ment of the heads. Third, uniform stand. The number of plants per acre may vary between seven and ten thousand. As with many other tilled crops, however, it is more essential to have the CABBAGE 307 largest number of plants possible in the rows, and the rows wide enough apart to permit free use of horse implements in tillage. This may cut down the number of plants per acre, but it will be economical in the end.” The points clearly brought out by these experi- ments are: (1) that the tonnage per acre of all varieties is large; (2) that the percentage of dry matter in all varieties is low; (3) that, as a rule, the larger the yield the lower the percentage of dry matter; (4) of the varieties usually grown, the OOOQIO Fig. 58. Forms of cabbage heads. In order: flat, spherical, obovate, oblong, conical. Surehead gave the largest yields in all the years, whether seeded in May and afterwards thinned, or whether grown as plants and transplanted in June; (5) the early planting produces the best yield of both fresh substance and dry matter. The most important points shown by these data is that cab- bage does not compare favorably in yield of dry matter with many forage crops that require but two or three months for maturity, and which per- mits of two or three crops per year. With cabbage, one crop is practically all that can be grown, as it requires a long season. 808 FORAGE CROPS The average composition and yield of nutrients per acre of cabbage are as follows: Onetou Average acre- eontains yield furnishes Per cent Lbs.

KOHLRABI Kohlrabi is another valuable member of the cabbage family, and one that may be fed withont risk at any period of growth. It requires a rich soil in order to attain its best development. If the land has been well prepared, it produces very heavy crops. There are a number of varieties, both bronze and green, but the green is almost exclusively grown. There are hardy, or big-topped varieties, and small-topped kinds, which come to KOHLRABI FOR FEEDING 309 quick maturity, but are not able to withstand the severity of winter, and are, therefore, useful only for autumn food. Kohlrabi is particularly suited for fillmg in gaps between other forage crops. A recent Cornell publication (Bulletin No. 244) speaks as follows of kohlrabi as a forage crop: “It and leaves. Background of six-inch squares. (Cornell Station. ) 310 FORAGE CROPS can be grown wherever rutabagas are grown, and will thrive if treated as described for the latter crop. In the middle West where rutabagas have a tendency to run to necks and form little root, this crop is a very good substitute. So far as now known, in New York the yields of the two crops are about the same, but both yielded less than mangels on the experiment station grounds. In addition to being quite a free-growing crop, it has the following advantages over rutabagas: “1. It is not so subject to clubroot or finger- and-toe (Plasmodiophora brassice) , and some other diseases. “2. It withstands drought better. "3. It can be grown on heavier soil, as clays, and does admirably on muck land. “4, It stands well out of the ground and can be readily pastured by sheep if desired. "5. It has not been known to cause taint of milk when fed to dairy cows. “6. Itis rather better than the rutabaga in with- standing frost. "7, It may be grown where the climate is too warm for the best development of the rutabaga. "8, The leaves are as valuable as the stem. “Among well-known varieties are the White Vienna (Fig. 59), Purple Vienna, Short-top White, Goliath, Carter Model.” CHAPTER XVII PERMANENT MEADOWS AND PASTURES THE raising of hay forms a very important part of the farming interests of the eastern and central western states. The aggregate area in hay is greater than in any other crop. While in parts of the eastern states the hay crop is deemed worthy of the best attention of the farmer, this is the ex- ception rather than the rule; therefore, while there may be profit from its growth, the yield and value are much less than should be secured were the crop given the same attention as the other crops in the rotation. In most instances, the hay is seeded rather as a catch-crop with wheat, rye or oats, and, while good catches are frequently se- cured, more often the stand is thin, thus reducing the yield, besides permitting the growth of natural grasses and weeds, and very materially reducing the quality of the product. Modern conditions would seem to warrant greater attention being given to this crop, and experiments show clearly that the hay crop will respond quite as profitably to good care, and the use of manures and fertili- zers, as any other field crop. (311) 312 FORAGE CROPS MEADOWS The main market hay is timothy, and market quality is reduced in proportion to the quantity of other kinds of grass mixed with it. Other grasses are of value, however, and these will undoubtedly be a feature in the hay markets, and exercise an influence in grading for market, when their value is generally known. From the standpoint of the grower, it is desirable to have more than one variety of grass, as it permits of thicker seeding and larger yield, for, when conditions are unfavor- able for one grass, they may be favorable for another. Besides, the conditions that are unfavor- able for the permanency of one grass may be favorable for the permanency of another, thus lengthening the period during which meadows may be profitably mown. Therefore, mixtures con- taining timothy, blue-grass, red-top, and other grasses of known value, in addition to the ordi- nary mixture of timothy and clover, are to be recommended. It is desirable that the varieties of grasses used in a mixture should mature practi- cally at the same time; otherwise, the mixture would contain over-ripe and under-ripe grasses, which would unfavorably affect the quality of hay. To insure permanency of meadows, it is not good practice to pasture them, as the tramping of the animals, especially should the land be wet, will MEADOW LANDS 313 destroy many plants, and the vacant places will be occupied by weeds. It is much better to utilize the second crop as hay or green forage. If pasturing is practiced, care must be exercised to see that it is not carried too far. Lands and their preparation Lands suitable for hay-growing range from sandy loams to heavy clays, although, on the lighter soils, more difficulty is experienced in get- ting a stand and in securing its permanence. On heavier lands, the grasses are more likely to secure their needed food, and to grow without deterioration for a longer period. The main point, particularly on the heavier lands, is to have the soil suitably prepared, if a good crop is to be guaranteed. The preparation usually given for the seeding of wheat or rye is generally very good for timothy and red-top, sown at the time of seeding the grain. As already pointed out, such seedings are not to be regarded as the best, as the purpose in the seeding is to secure the grain crop rather than the grass, and the grass crop is assured only when the conditions are all favorable for germination and subsequent growth. It has been demonstrated that, in order to secure the best results, the land intended for permanent meadows should be specially prepared, 314 FORAGE CROPS not only plowed deep, but frequently and thor- oughly cultivated, both to destroy weed seeds and to put the soil in an exceedingly fine tilth, which promotes the solubility of plant-food and permits the easy penetration of the roots of the young plants. It has been shown, also, that grass thus seeded does not usually require a nurse-crop, and that such seedings will give a larger yield of hay, the following season, than can be expected when seeded with grain in the customary way. Seed and seeding When seeded for permanent timothy meadow and for market, hay is the object sought; hence, if land is well prepared and clean, twenty to thirty pounds of seed should be used, although it follows that with this thick seeding abundance of avail- able food should be present. The common practice of mixing timothy and clover is a good one, as gen- erally a larger crop is obtained the first season—a sufficient increase to pay, although the selling price is lower for mixed hay. In this case, the follow- ing mixture of seed has been found to be good (using twenty to twenty-four pounds of seed per acre) : Timothy ss. a eee, wee wes es eae wo 12 pounds Red clover .....-. 2.2. ee eee 4 pounds AVBIRO 2 e. ) el coche oe es es eC 2 pounds Fig. 60.

The following mix- ture of seed has been found to be most excellent for lands well adapted to grass, the finer grasses making a thick sward, and insuring a larger yield: Timothy ..........+.+.- +... 8 pounds Red clover... 1. et ee ee we ws 4 pounds AISIKG, | secs tes ap apd ay RL es Se SS 2 pounds Kentucky blue-grass ......- eee 2 pounds Redstop: ic ee eee Se we 2 pounds On clay loam lands that are naturally moist, the red-top and blue-grass are likely to crowd out the timothy, leaving a practically pure seeding of the red-top and the blue-grass. These make hay that is not readily salable, although, if cut when in full head and before the seeds have ripened, it is readily eaten by cattle. If allowed to ripen, the quality is much reduced, as it is not only unpala- table but is less digestible. Timothy for market should be cut as soon as the blossoms have dropped and the seeds formed, but not hardened; the leaves are still bright, while the yield has practically reached its maximum. Whatever the mixture, the seeding may be made in the early fall, during a period ranging in southern sections from the latter part of August to early in October. The main point is to have the seeding made early enough to ensure a good growth before winter, and late enough to avoid FERTILIZING MEADOWS 317 such summer weeds as vrab-yrass. Unless too large growth is made the first fall, it should not be removed nor pastured, but allowed to remain on the land. If heavy growth is made, it is better to mow, rather than to pasture it off before winter. Manures and fertilizers In seeding down meadows for permanent mow- ing, it is very important that the land, even though naturally fertile, be well supplied with available plant-food. This may be either barnyard manure or commercial fertilizer; in the absence of barnyard manure, commercial fertilizers can be depended on exclusively. In the use of barnyard manure, the quantity applied should range from six to eight tons per acre, preferably in fine condition, distributed evenly, and thoroughly cultivated into the surface soil. This should be supplemented at time of seeding by a fertilizer mixture made up largely of phosphates and potash salts, as the manure will supply an abundance of nitrogen to give the plant a start and insure its growth the first season. A good formula or mixture for application at time of seeding is the following: Nitrate of soda... 1... 2 ee eee 50 pounds Ground tankage or bone ....... 200 pounds Acid phosphate ..........-. 600 pounds Muriate of potash .......... 150 pounds 318 FORAGE CROPS This application, when used without manure, may be 300 to 609 pounds per acre; with manure, about 200 to 350 pounds per acre. This should be applied previous to seeding and well harrowed in. If the stand on young meadows is good, no top- dressing is needed the first year, on good lands. In spring, after the first year, the meadow should be top-dressed with a commercial fertilizer, or with finely divided manure early in the season, in order to supply the food needed for the rapid growth, as well as to encourage the deep rooting of. the grasses, and a thickening of the sward. The mixtures for spring top-dressing should contain a large proportion of nitrate of soda, as this is the one form of nitrogen that is soluble and readily diffusible in the soil; this will penetrate deeply and encourage a deeper rooting of the plant. A formula made‘up as follows is one of the best: Nitrate of soda... ......-206 500 pounds Ground bone. ............ 200 pounds Acid phosphate... .......6.. 200 pounds Muriate of potash .......... 100 pounds The summer or fall applications may contain a larger proportion of the minerals, and a formula made up of Nitrate of soda. . 2. 2... 2.2.2.2 ee 200 pounds Ground bone... .. 2.6.20 0% 200 pounds Acid phosphate... ......... 500 pounds Muriate of potash .........2.. 100 pounds FERTILIZING MEADOWS 319 may be used in order to encourage the growth of the second crop, or aftermath. For this purpose, an application of 150 to 300 pounds of the mixture per acre may be made. Experiments to determine the most useful quantity show that, for the spring top-dressing, as high as 450 pounds of a mixture rich in nitrate, as the one above, will pay better than smaller applications, although in many in- stances, where the areas are large, farmers are not prepared to provide so large an allowance. These top-dressings, as already pointed out, may be either manure or fertilizer, but they should be applied every year, if permanence and good crops are expected; and, while the proportions of the different grasses may change somewhat, experi- ence shows that the yields will be more profitable and will gradually increase, owing to the improved fertility of the land. Experiments at the West Virginia Experiment Station show that the use of manure alone, when applied to a soil not highly fertile, caused an increase in yield from less than two tons per acre in the first year to over five tons per acre in the sixth year, and with nitrate of soda alone to about four tons. The average for the six years was four tons and over, for the manure, and three tons and over for the nitrate. “The entire meadow produced hay during the six years of the test to the value of more than thirty-six 320 FORAGE CROPS dollars per acre per year, in addition to paying for all the fertilizer applied, while the land at the close of the five years was more valuable than at the beginning of the test. This plan of growing hay would not only result in increasing the value per acre to the farmer, but largely improved his soil for other crops.” Recent experiments at Cornell (Bulletins 232, 241) did not give very encouraging results on tim- othy with fertilizers alone (muriate potash, acid phosphate, nitrate of soda, and combinations) as compared with good stable manure: “It is per- fectly obvious from these experiments that, on the Dunkirk clay loam on which this experiment was conducted and in this climate and under the conditions of this experiment, stable manure, at fifty cents a load,! brought much better finan- cial results than any application of commercial fertilizer at current prices for the same. It also demonstrates that on this soil, which has been under cultivation for two or three generations, when stable manure is available, excellent crops of timothy hay may be produced. Where stable manure can be procured in sufficient quantity, the use of commercial fertilizers is not necessary. 1In making such comparisons as this, everything depends on the value placed on the manure. It is possible that fifty cents a loa for manure is a comparable price on some farms, but farmers cannot buy manure and haul it at this figure. One dollar a load is probably a fairer price; and for city manures even this figure must be at least doubled. FERTILIZING TIMOTHY 321 On the other hand, these experiments give rea- son to believe that, when stable manure is lack- ing or not sufficiently abundant, commercial fertilizers may be used, if used judiciously, with good results. “For the New York farmer, especially those who wish to raise the maximum amount of hay, a judicious blending of stable manure, legumi- nous crops and commercial fertilizers will prob- ably bring both the maximum yield and the most economic returns. For the farmer who wishes to raise a larger proportion of hay on Dunkirk clay loam, an eight-year rotation may be suggested: hay, five years; an intertilled crop, such as corn, potatoes, beans, mangels, rutabagas or cabbages, one year; oats, one year; winter wheat or rye, one year. Timothy would be seeded in the fall with the wheat or rye and a mixture of red and alsike clover the following spring. In this rotation stable manure should be applied to the grass land before plowing for the cultivated crop. No fertilizer of any sort need be applied for oats. To the wheat apply commercial fertilizer relatively high in phosphoric acid and potash and low in nitrogen. Apply in the spring to each grass crop, just as soon as the grass starts, commercial fertilizers relatively high in nitrogen and low in phosphoric acid and potash. Mixed fertilizers usually contain too U 322 FORAGE CROPS high a proportion of phosphoric acid and too low a proportion of nitrogen for the production of timothy hay upon the soil and in the climate under consideration. It would probably be best for the farmer to buy the separate ingredients and mix them himself. The following mixture or its equivalent is recommended, nitrate of soda, 200 pounds; 16 per cent acid phosphate, 100 pounds, and muriate of potash, 80 per cent purity, 50 pounds. Whether this quantity should be applied per acre, or a greater or less quantity, can best be determined from the history of the land and the appearance of the meadow from year to year. In the experiments under consid- eration, only acid phosphate has been used as a source of phosphoric acid, although experiments at the Pennsylvania and Illinois Stations indi- cate that finely ground phosphate rock may, in the course of a rotation, be equally useful.” PERMANENT PASTURES The treatment of permanent pastures follows the same general procedure as for permanent meadows. In many parts of the country, past- ures occupy the rougher areas of the farm. In some instances they are too wet, in others too rough, and in practically all cases no attention is given to their improvement, either in the way “ssva3-an|q pus dojz-pea ‘AyjOUIT} :sessvAS paX{Ul Jo MOpvol Ul 9UEDS Surljsearvyy “19 “Sl ss Sees = Se ee a ee = 324 FORAGE CROPS of added fertility, or of drainage, or in cleaning the land of foreign growths. Experience has shown that pastures may be very materially im- proved, and at slight expense, if careful plans are made and a definite system of treatment is laid out and practiced. In the preparation of the land, and seeding, the suggestions already made for meadows may follow, except that many grasses will serve as pasture that are not so well adapted for hay; besides, the objections made to mixtures for hay do not hold good for pastures, as the, farmer uses them for his own stock rather than offers them for sale. Seed mixture The following mixture of grasses and clovers will probably answer quite as well as any other, in the seeding down of pastures, as the variety of grasses is such as to insure a thick sward, as well as to provide for both early and late grazing: TIMOthy soc.

Since the pasture is to remain for a long period, it is usually important that the land be well limed, using from forty to fifty bushels per acre, and thoroughly harrowing it into the soil in the summer before the seeding. This will not only sweeten the soil, but will encourage the growth of clovers and other valuable legumes, which are always desirable. Top-dressings should then be made at least once each year, preferably early in spring before the animals are turned on. The mixture may be similar to that recommended for meadows, applied at the rate of 200 to 300 pounds per acre. If ap- plied in the fall, after the pasturage has ceased for the season, one not containing nitrates is prefer- able. An equal mixture of kainit, ground bone and acid phosphate has been found to be very useful, at the rate of about three hundred pounds per acre. This top-dressing not only causes a thicker growth of the nutritious grasses, but encourages a tendency to deep rooting, and thus a greater resistance to drought, besides improving the soil from year to year and preventing running out of 326 FORAGE OROPS the grasses, which is so common on neglected pasture. Weeds and brambles which are not consumed by stock should ‘be removed each year, preferably in August, at which season the destruction of the plant is likely to result. Systematic management and treatment of pastures will result in many in- stances in increasing the yield more than two-fold; this should be a part of the practice of every far- mer. On rough lands, where it is not possible to plow and prepare the soil and where grasses come in naturally, the permanency of the pastures may be increased, and the quality improved, simply by dressing with commercial fertilizers, using mainly ground bone, acid phosphate and muriate of pot- ash, and liming once in about four years. Many hill pastures, that furnish scanty herbage, may be very quickly improved by this method, and the yield of forage very largely increased. In these cases, the soil is frequently dry and poor, and it requires only that the minerals should be applied, in order that the plants may develop more rapidly, and continue for a longer time. Renewing old pastures Old pastures that have become sod-bound and mossy may be greatly improved by scarifying with ‘ any suitable tool; a spike-tooth harrow will answer PERMANENT PASTURE 327 the purpose, as it will do greater service among stones and stumps than most others. Lime the land at the rate of twenty-five bushels per acre, and fertilize with the mixture of ground bone, acid phosphate and kainit at the rate of 200 to 500 pounds per acre. The stirring of the soil will let in the air, the lime will sweeten it, and the fertilizer will provide additional food. Seed should then be sown and lightly covered. The expense is not great, while the value of the pasture is manifestly improved, and its greater permanence assured. CHAPTER XVIII BERMUDA-GRASS AND RUSSIAN BROME GRASS Timotuy, red-top and June-grass are the staple meadow and pasture grasses of the older parts of ‘the United States. The remarks in the preceding chapter apply specially to them and to combi- nations with clovers. There remain very many grasses of recent introduction, or which have lately come into notice, but a discussion of them is searcely called for in a brief popular work of this kind. Two other grasses, however, need to be specially considered, and a discussion of them now follows. BERMUDA -GRASS Bermuda-grass is now regarded as one of the most valuable grasses for the southern states, par- ticularly for pasture. It is perennial, the creeping stems of which produce nodes at short intervals; each joint is capable of producing a new plant, even though it is cut off and completely separated from the main stem. It is because of this charac- teristic, although valuable from the standpoint of securing a thick stand, that many farmers object to its introduction, as, after it is once seeded, the (328) BERMUDA-GRASS 329 cleaning of the land is very difficult. Many growers now think that, when rotations are desired, it is not necessary completely to clean the land of Bermuda-grass, since, if a few joints are left, these serve to bind the land and to hold moisture; then, when the grass crop is wanted again, enough joints remain alive quickly to form a complete cover. The plant makes a thick, leafy growth with branches of five to ten inches in height. It is the common lawn grass of the South. Bermuda-grass is a hot-weather plant, and- thrives only in those regions in which the winters are short, and the frost does not penetrate deep or persist for a long time. It grows through the entire summer. While it will make a much better yield on good lands, it is also well adapted for pasture on poor lands, and on those liable to wash and gulley; and its power of withstanding heat and drought, and to revive quickly when moisture comes, are among its valuable characteristics. It grows best on light soils, river-bottoms and at the foot of hills, where the soil has been washed from the higher levels. Its habit of throwing out under- ground stems, makes it better adapted to sandy lands than to stiff heavy clays; nevertheless, when once well established on the heavier soils, it is serviceable. It has rendered great service in the South in preventing the washing of lands, a danger that is common in the southern states. 330 FORAGE CROPS Preparation of the land As with other grass plants, the better the prep- aration of land, and the cleaner, the quicker will the stand of grass be secured. The conditions which result from the planting and care of corn, cotton and tobacco, provide a suitable preparation for Bermuda-grass. Owing to the high price of seed and its low vitality, the method now generally used to secure a stand, is to plant pieces of root- stocks rather than to seed in the ordinary way, although it is necessary to have a small area seeded to use as a cutting nursery for enlarging the area. For this purpose, the seed should be sown broadcast, on clean, moist land, and covered with a rake or light harrow. Five pounds of seed is sufficient for an acre. This plant responds well to fertilizers, and top- dressings with nitrate of soda, where the soils have been suitably fertilized with minerals at time of seeding, are very profitable. Bermuda-grass for pasture or meadow The following methods of securing a pasture or meadow of Bermuda-grass are described by Prof. F. Lamson-Scribner!:— “On account of the high price of seed, and the Circular 31, Div. of Agrostology, Dept. of Agr., Washington, D. C. BERMUDA-GRASS 331 necessity of a thorough preparation of the soil, pastures and meadows are more often started from cuttings. To prepare cuttings, the sod is gathered and cut into small pieces with a feed cutter or other similar machine, or a wooden block and hatchet can be used if only a small quantity is needed. Since most of the propa- gating stems are near the surface, it is necessary to shave off a layer of sod only an inch or two thick. If cuttings are wanted in large quantities, the sod can be plowed and the roots harrowed into windrows or piles. In all cases care should be taken not to allow the roots to get dry. The cuttings may be planted at any time of the year in the South, except the coldest winter months, but the work is usually done in March. If a meadow is desired, more care should be taken in the planting of the cuttings to insure a level surface for the mowing machine. The cuttings are planted by dropping them at intervals of a foot or two in shallow furrows, and covering with the next round of the plow. This can be done when the field is plowed, the cuttings being dropped every other round or every third round. Or the field can be prepared first and the cut- tings dropped upon the surface and pressed in with the foot as they are planted. For meadows it is best to go over the land with a roller after planting. For pastures, when a smooth surface 332 FORAGE CROPS is not necessary, it is sufficient to plow shallow furrows every two to four feet and drop the cut- tings therein, covering them with the foot or by turning the soil back over them with the plow. “Professor Tracy remarks:—‘So easily may Bermuda-grass be propagated that good stands ean be secured by scattering a dozen or more sods to the acre and cultivating the land in corn or cotton two or three years, when the grass becomes distributed in the field.’ ” Yield and value of crop Bermuda-grass is relished by all kinds of live- stock, and in all stages of growth, making a palatable snd nutritious pasture and hay. Owing to its drought - resisting qualities, it provides pasture throughout the entire summer season, which ranges from seven months, in North Caro- lina, to nearly the entire year in the far South. It is not desirable, however, to graze throughout the entire year, as grazing naturally reduces the vitality of the plant. Neither should it be grazed too closely soon after planting, as this has a tendeney to destroy the runners, thus prevent- ing the formation of new plants. On established pastures, however, close grazing is desirable, because the pasture is more palatable,—the stems not becoming hard and wiry and less digestible. BERMUDA-GRASS 333 For use as hay, the crop should be harvested when a large proportion of the stems are in bloom. The number of cuttings in a season must depend on soil and season, ranging from one to four per year, with a total yield of one to three tons per acre. The following reports! from the states indicated show that Bermuda-grass is highly regarded and likely to prove one of the most valuable forage crops: *Alabama.— This grass will grow under the most flagrant neglect; while care and cultivation will bring out its characteristics to a marked de- gree, and will repay the cultivator for all his ex- pense and trouble. It is an excellent grass to prevent the washing of the land, for filling up gullies and preserving terraces. It makes one of the best lawns on account of its smooth and regu- lar growth, and its power to withstand the heat of the sun. The Bermuda-grass is not so difficult to eradicate from the field as most farmers seem to think. Close cultivation in cotton for two or three years, and thorough pulverization of the soil will destroy this plant. * Arkansas.—Bermuda-grass is the best summer pasture grass we have for the sandy soils of south Arkansas, and is one of the best hay grasses for all parts of the state, except the northwestern ' Bulletin No. 55, Oklahoma Experiment Station, 334 FORAGH CROPS part. It is not generally regarded with much favor, but, where it has established itself and is being utilized, it is regarded with great favor. On the barren soils it does not succeed, but it suc- ceeds on all other soils whether wet or dry. It makes hay of superior quality that is highly rel- ished by live-stock. When the value of Bermuda- grass for hay, pasture and a soil-renovator is appreciated, and the proper methods for cultivat- ing and controlling it are understood, it will be a highly appreciated grass. Shade is fatal to the grass, and by using the harrow, then oats, then cowpeas and cotton, the grass can be subdued and eradicated. To start the grass by seed is uncer- tain. The cheapest and best way is to start to turn up a Bermuda sod and harrow the roots into piles, then chop them into short pieces with a hatchet and sow them on freshly broken soil and plow them in. The roots must not get dry while out of the ground. * California.—This grass has introduced itself in a bold and uninvited manner. Its perfect adap- tability to the conditions is evidenced by the thrifty growth on all kinds of soil, including strong alkali, very dry and very wet, producing more than any other grass (without care or planting), abundant feed during nine months of the year. The objec- tions to this useful grass are mostly founded on the prejudice of the people, which renders them BHRMUDA-GRASS 335 blind to their own interests. Many men are wear- ing out their lives in poverty, trying to grow fruit on land poorly adapted to fruit-growing, but emi- nently adapted to Bermuda- grass. * Louistana.—For winter and early spring, Texas blue-grass and the clovers seem to fulfil all the requirements, followed in summer by Bermuda- and crab-grass, the two best grasses we have. It was impossible during the wet summer to restrict the last two to the plots allotted to them, but to- gether, they covered the whole area of the (grass) garden, yielding several cuttings of hay for our work animals. * Mississippt.—This grass is the most valuable species we have in the South, and is too well known to need any description. It succeeds best on rich bottom lands and on the black prairie soil, where it will yield two cuttings in a season, mak- ing two to four tons of hay per acre. This hay is of the very best quality, being especially valuable for horses and mules.” J. S. Newman, in Bulletin No. 76, of the South Carolina Station, says of the plant: “This most valuable acquisition to our list of pasture grasses seems to have come from India, where it is called ‘Dhab.’ "Until its great value as a pasture grass and, on moist, fertile soils, as a hay producer, became known, it was regarded as a pest by the cotton 336 FORAGE CROPS planters all over the southern United States. Many plantations, in the south Atlantic states, were abandoned on account of its prevalence upon them, which are now yielding more profitable returns from Bermuda pastures and Bermuda hay than were ever realized from the same fields while cultivated in cotton. There is a well authenticated record of 13,000 pounds of Bermuda hay, per acre, from three mowings during one season, on the Oconee river-bottoms in Georgia. “Farmers who, a few years since, dreaded its appearance upon their farms as they did Canada thistle or the famous coco or nut grass, are now industriously planting Bermuda pastures and meadows.” Meadows of Bermuda-grass should be renewed once in three or four years, as the tendency is to become sod-bound. The meadows may be re- newed by deep plowing, and seeding in the late fall with any of the crops usually grown for spring pasture or soiling; vetch and winter oats have been used for this purpose with great success. An abundance of seed should be used and the land well fertilized in order to insure a vigorous growth that will help to choke the grass. The sods and roots left will spread rapidly after the forage crops have been grazed or cut, provided the land is naturally fertile, or has been even manured or fertilized, BERMUDA-GRASS 337 Methods of eradication “The very qualities which render Bermuda so valuable as a pasture grass serve to make it an aggressive and pestiferous weed. On account of its tendency to spread and insinuate itself into land where itis not wanted, and to persist in fields which are to be used for other purposes, it has, in many cases, not been utilized to the extent that its good qualities would indicate. However, it can be eradicated from a field with comparative ease by proper cultivation. Since it will not thrive in the shade, it is only necessary to smother it out by some. quick-growing crop. A method recommended by southern agricul- turists, and which may be modified to suit con- ditions, is to .plow the land after the last crop of hay is cut, if the field is a meadow, or about this season if it is a pasture. Sow the field to oats, wheat or other thick-growing crops. When this crop is harvested, plow the land immediately and plant to cowpeas. It is probably best to plant these in drills and cultivate them until the vines meet, after which they will shade the ground and prevent the growth of Bermuda. Usually this treatment is sufficient to completely destroy the Bermuda; but if not, the process can be repeated.” (Circular No. 31, Division of Agros- tology, Department of Agriculture.) v 338 FORAGE CROPS RUSSIAN BROME GRASS (Bromus inermis) (Figs. 62, 63) This perennial grass was introduced into the United States in 1882, and is now widely grown in Canada and in North and South Dakota, and in the western parts of Minnesota, also in Kansas and Nebraska, and in parts of many other of the western states, both because it is itself a good grass crop and because it resists cold and drought. The habits of growth of this plant are similar to those of quack-grass; it has creeping root- stocks, branching out in every direction, and these produce at each joint a bud, which is capable of producing another plant. It grows to an average height of about two feet, although under good con- ditions it will reach a much greater height. The leaves are broad, thick and abundant, when the soil is good. This grass makes a large yield, because of the thickness, even though the height is somewhat reduced. It is well adapted to light, dry soils. It starts in spring earlier than any of the other valuable grasses. It matures usually in the month of June. It is a very palatable grass, all animals being fond of it. Because of its habit of growth, it makes a valuable pasture throughout the entire season, and is also useful as hay. The yields from an average crop are one and one-half to three tons per acre. Bromus inermis is adapted to a wide variety Fig. 62 Bromus inermis. Photographed by H. L. Bolley, North Dakota. 340 FORAGH CROPS of lands, although it seems to do very much better on light sandy soils, deficient in moisture. This makes it a useful plant where others would not grow well; but it does not follow that it will not grow much better on soils of higher fertility. This brome grass is not well adapted to a rotation of crops, because of the difficulty of cleaning the land, although this is less difficult than in the case of Bermuda-grass. It should not be allowed to grow for a long period without breaking up, if used in rotations. Fertilizing Bromus inermis In renewing either pastures or meadows of Bromus inermis that are too thin, seed may be added in the fall and lightly covered with a har- row, although a’ thin stand will ordinarily thicken up sufficiently, if the plant-food is ample. As with other grasses, fertilizers or manures are beneficial, and top-dressings of manure, either in the late winter or early spring (four to six loads per acre), or top-dressings of nitrate of soda when the plants are well started, will usu- ally pay well. ‘When lands are rich and moist, there is sometimes difficulty in destroying the grass, when land is broken for other crops; but if plowed deep and followed by one or more cultivated crops, there need be little anxiety on this score. . at “S2U4dU2 SNMOLG ‘SSBIF BTIOIQ UvIssNy Jo plelq ‘eg “ST 342 FORAGE CROPS The preparation of land, and seeding Russian brome grass does not grow rapidly the first season. Therefore the land should be well prepared and free from weed seeds before planting. It is more desirable to sow after a cultivated crop, or on land that has been sum- mer-fallowed part of the season. The good preparation necessary for the seeding of any grass will answer. It may be sown in fall or spring, although, under average conditions, the most favorable time is the early spring, especially if sown with a nurse crop. If seeded in August or September, on land that has been well pre- pared, it should make a good crop the following season. In the South, it is preferable to sow in the fall, owing to the fear of destruction by the hot, dry weather of the following summer. When seeded without other grasses, twelve to fifteen pounds per acre is sufficient, when in- tended for hay; sixteen to twenty pounds should be used when intended for pasture. When it is a part of a combination of other grasses, the proportions may be two to five pounds, according to the object of the seeding, although little expe- rience has accumulated in this country as to its permanent character in pasture and meadows. Its natural tendency is to crowd out other less vigorous grasses BROME GRASS 343 Pasturing and harvesting For pasture, the brome grass will stand close grazing, particularly on good lands, but if pastured very late and close in the fall, the yield of the next season’s crop is likely to be reduced. In cutting for hay, it should be harvested wher fully in head, although for horses it may be cut- when the blooms have disappeared. Probably the best time for cutting, as for other grasses, is when the plants are in full bloom. The cut- ting and curing does not differ from the methods recommended for timothy, or the other better known grasses. CHAPTER XIX COMPOSITION, FERTILIZER AND COEFFICIENT TABLES Tus chapter contains tables showing the aver- age composition of American forage crops and feed stuffs, together with the fertilizer constitu- ents contained in them, and the average coeffi- cients of digestibility. The analyses represent the average as near as may be, although it should be understood that average compositions of products of varying qual- ity are a guide only when accompanied with knowledge of the possible variations that may occur; they are chiefly useful in showing differ- ences in the composition of groups, rather than giving exact information as to what may be ex- pected under different conditions. This is particu- larly true in the case of crops used for green forage, as the range in content of dry matter is very wide, owing to the necessity of beginning to harvest when the plants are immature and con- tinuing it so long as they remain palatable. The composition of fine feeds also varies widely, although it is possible now to so classify as to eliminate the variations that formerly existed. (344) COMPOSITION TABLES 345 The tables showing the average fertilizer ingre- dients of fodders and feeds are also subject to the same criticism, although not to the same degree. These data are of special service, in the case of farm crops, in showing the relations between the different classes, and, in the case of fine feeds (which are not forage-crop products), in indicat- ing the gains or losses that may be incurred in the exchange of home-grown herbage feeds for the more concentrated refuse or by-products. The average coefficients of digestibility are also subject to variations, as must be apparent to those who give the matter consideration. They are to be used as guides only, and not as absolute facts. The data contained in these various tables have been derived from a number of sources, but mainly from tabulations of analyses made by the various experiment’ stations of this country. The coefficients of digestibility are the averages of American digestion experiments contained in the report of the Hatch Experiment Station of Massa- chusetts, for 1906. PLAN OF TABLES I AND IL 1.
