In favorable years, however, good crops have been raised by planting cowpeas into disked stubble jand. Cotton sometimes fails to make a stand. Late replanting is rarely profitable, but there is usually time to plant cowpeas after the cotton has been abandoned. Early potatoes should be followed by a crop of cowpeas instead of by a second crop of potatoes. Wherever a crop has been removed in time or there is a vacant patch of land in June, it should be put to use growing cowpeas instead of being permitted to grow up to weeds. 169. For green manuring, to be plowed under for soil improvement, cowpeas are a profitable crop. They should be turned under when the plant is at the highest stage of growth, just before it begins maturing. This will actually add to the supply of plant food in the soil, some of the nitrogen of the plants being obtained from the air through the action of the bacteria in the nodules on the cowpea roots. The vege- table matter after it decays will also improve the soil and make it work better. If the soil is sandy, the soil grains will be held together by the decayed cowpeas and will have less of a tendency to blow. If the soil is tough and pasty, it will be loosened to some extent and work better. As a rule, land where cowpeas have been turned under in August or September THE FORAGE 105 should not be sowed to wheat or alfalfa in the fall but should instead be planted to crops the next spring. It takes time for the material to decay and the soil to settle to a good seed bed. Wheat may be sown on land from which a crop of early cowpeas has been pastured off or cut for hay. 170. Good feed is wasted, however, when a crop of cowpeas is plowed under. It is more profitable to get their full feeding value, if pos- sible, and put the resulting manure on the land. Cattle may be pastured on cowpeas with profit if care to prevent bloat is taken when they are first turned in. They should be turned in at first in the evening for a short time until they become accustomed to the large supply of rich feed. Hogs often do not pasture satisfactorily on cowpeas, especially if turned in before any of the pods have ripened. They may dig up and eat the roots, leaving the tops to waste. But there is no more economical way of harvesting a cowpea crop than by pasturing it with hogs after most of the pods have matured. Gains will be better if they have a light feed of ground kafircorn or milomaize to balance the ration while pasturing on the cowpeas. Even after the vines have been killed by frost, horses and eattle will continue eating them and hogs will gather the seed. 171. Cowpeas for hay should be cut before the bottom leaves begin drying, while still 106 SURE FEED CROPS blooming at the top but after the pods have begun ripening at the bottom. Cultivation of cowpeas to be cut for hay should be such as to leave the land level and free from ridges. The crop is usually cut with a mower but, if the grain is ripened, this shatters much of it. Better work can be done with the mower by using an extension on the guards to lift the vines. The roots may be cut off with a sharp plow with the moldboard removed, or with a sharp iron prop- erly bent and attached to a plow beam. As with alfalfa, the curing is best effected by keep- ing the leaves alive and transpiring water for as long a time as possible after cutting. After wilting in the swath, the curing should be con- tinued in the windrow and, if necessary, in small piles. The more thoroughly cowpea hay can be cured without losing its leaves, the better the condition in which it will come out of the mow or stack. Cattle will eat badly dam- aged cowpea hay but its feeding qualities are not improved by its having become mouldy or blackened. 172. The feeding value of cowpea hay for all farm purposes is essentially the same as that of alfalfa hay. (152.) It varies widely, de- pending upon the amount of matured grain which it contains and the percentage of leaves lost during the curing. Cowpeas contain 16.8 percent. digestible protein, 54.9 percent. diges- tible carbohydrates, and 1.1 percent. digestible fat. The hay, without the grain, contains 5.8 THE FORAGE 107 percent. digestible protein, 39.3 percent. diges- tible carbohydrates, and 1.3 percent. digestible fat. For horses, dairy cattle, and fattening steers and hogs, cowpea hay may be used for every purpose that alfalfa hay can be used and the results will be practically the same. Ut isa rich feed, difficult at times to care for and cure properly, but one which should be grown and fed much more extensively as one of the sure feed crops adapted to Central Southwestern conditions. 173. Varieties. Numerous varieties of cow- peas are grown. The Whippoorwill is the most common, though different types are often sold under this name. It isa variety which produces a good growth of vine and a fair yield of seed. W. P. Camp of Washita county, Western Okla- homa, has made variety tests of cowpeas and sums up their general adaptabilities as fol- lows: For hay— Whippoorwill, Iron, New Era, War- ren’s New Hybrid, Red Crowder. For seed—Michigan Favorite, Whippoorwill, Groit, Brabham. For quick maturity—New Era, Warren’s Extra Early, Michigan Favorite, Whippoorwill. For slow maturity—Red Ripper, King, Un- known, Clay. For heavy vines—Unknown, Rep Ripper, King, Clay, Brown Crowder. One early and one late variety are desirable on every farm. 108 SURE FEED CROPS 174, Cowpea seed are usually high in price because of the labor necessary to save the seed. The ripe pods are picked by hand, children usu- ally doing the work. These are later either hulled with machinery or flailed out. Small hullers, run by hand or a gasoline engine, do satisfactory work. Some seed is saved by stor- ing hay containing ripe seed in mows with tight floors. As the hay is fed cut, the seed are shaken down and later cleaned off of the floor. Special cowpea threshers which thresh the grain from the entire plant without cracking the seed are now coming into more general use. Grain threshers do not do satisfactory work with cow- peas. They crack too large a proportion and spoil them for seed. 175. Weevil damage in cowpea seed is a fre- quent source of loss. This may be prevented by placing the cowpeas in a tight bin or box and putting in with them, in open dishes or by pour- ing through a pipe into the middle of the pile, one pound of carbon bi-sulphide for each thirty bushels of grain. The bin should be kept tightly covered and fire should be kept away until the odor disappears. This treatment will kill the weevils and similar treatment two weeks to a month afterward will kill any others which may have hatched out. Another method consists in putting the cowpeas in an air-tight bin, then fill a number of small bottles with carbon bi-sul- phide, cutting a notch in the stopper of each. THE FORAGE 109 Set these bottles in the cowpeas and let them keep up continuous treatment for weevil. 176. Practical experience is necessary to adapt the cowpea crop to varying soil condi- tions. An excellent illustration of this is fur- nished by the following report from P. R. Slack of Major county, Western Oklahoma: ‘A few years ago, I became a convert to the planting of cowpeas and although I have had some partial failures, I have never become a backslider. My farm is in the blackjacks and the soil is very sandy. I cut the cowpeas with a cutter and the fields being left bare of vegeta- tion, how that soil did blow! I had to dig my wire fences out of the sand banks in the spring. But I realized that the fault was not with the cowpeas so I tried drilling the field to wheat or rye, merely as a cover crop after the cowpeas were taken off. ‘‘In the summer of 1911, during the dry, pareching weather, my field of cowpeas was a rich, dark green, showing no trace of dry weather, while the corn was parched and suf- fering for moisture. The soil has been im- proved by plowing under a green crop of rye or wheat every year on land which was in cowpeas the previous year. The soil did not blow badly in the spring of 1912, even with the bad dust storms we have had. ‘To prepare the soil for cowpeas, I plow during May after the other crops are out of the way and the weeds have obtained a good start, 110 SURE FEED CROPS preferably land which was in kafircorn or broom corn the year before, using a chain to wind under all weeds and trash. I follow with a harrow and any time in June, after a good rain or two has settled the soil, list shallow— from two and a half to three inches deep. Make furrows not more than three feet apart. Drill right after the lister so as to put the seed in moist earth, drilling about one peck to the acre, one seed each three to four inches in the row. ‘‘T then cultivate two or three times, oring- ing the soil to the plants from the fi t. In hard land, it might be well to plow earty, but I wish to get all the humus possible into the soil so prefer to plow after the weeds get a good start. A furrow opener attachment to a corn planter would be a fine thing to use in planting the cowpeas. I have planted cowpeas as late as July 15 and they fully matured a heavy crop of seed. I have also found that those planted after the middle of June remain free from weevil until warm weather the following season, while the early-planted are badly infested dur- ing the fall of the year in which they are grown. ‘‘Hor cutting cowpeas, I use the following: Take an old plowbar and a piece of corn sled steel about twenty-six inches in length to the blacksmith shop and have the steel welded to the bar, at an angle of a little more than forty- five degrees, making the steel of knife lie nearly flat. Puta brace across from bar to knife. Bolt . the bar to a riding plow or lister, and put on THE FORAGE 1H your rolling coulter with a crooked shank so as to cut the vines as far from the row as possible. Tf the soil is hard or dry, the lever can be set to cut at the surface; if loose and sandy, it should be set to cut under the surface. ‘‘TIn our dry climate, I always cure cowpea hay in the shock, shocking immediately after the cutter and putting about eight rows in one shock row. If I can get help, I prefer shocking entirely by hand, as many cowpeas are lost in raking. In favorable weather, the crop will cure enough to stack in three weeks. In regions of greater rainfall, shocks should be made smaller and high and narrow. The hay will not shed water readily and should be stored in a mow or the stacks should be covered with some material which will shed water. ‘‘T plant the Speckled Crowder exclusively, as it yields fully a half more seed than any other variety I have tried, besides yielding a heavy crop of hay.’’ PEANUTS 177. Peanuts earned a place among the sure feed crops in Oklahoma in the dry season of 1911. The total acreage planted to this crop was not large but it was for the most part widely scattered and the returns were generally profitable. 178. In Western Oklahoma, the returns from planting the Spanish peanut have been care- 112 SURE FEED CROPS fully investigated by George Bishop and the information gathered up to the fall of 1911 has been reported by him as follows: ‘‘My attention was attracted to the hardiness of the Spanish peanut when I found a farmer in Western Oklahoma who had been growing them for several years. The first year I visited his farm was in 1909, and he had planted ten acres of peanuts and ninety acres of corn. This turned out to be the first of the recent series of dry years. The corn was planted in April and the peanuts on May 10. The unfavorable crop season cut the corn yield to thirteen bushels per acre, while the peanuts yielded forty bushels per acre. In 1910, the difference was even grector, though neither the corn nor the pea- nuts made as much as the year before. Again in 1921, when the corn was an entire failure, the peanuts endured the heat and winds until the rains came in July, then went on and made a vield of twenty-five bushels per acre. ‘‘Another field in the same locality was planted in alternate rows of corn and peanuts. This was done for the special benefit of the corn and not for the peanuts. The intention was to give the corn a wider feeding area for its roots at maturing time, due to the later planting of the peanut. The peanuts, being planted six or eight weeks later, would not naturally use their share of the moisture. This — eorn field remained green several weeks longer than fields adjoining, planted in the regular THE FORAGE 113 way. The corn, though using the peanuts’ moisture for several weeks, was compelled to give up before rains came July 19. The peanuts went on and finally made a yield of fifteen bushels per acre. This was undoubtedly as severe a test as could be asked for.’’ 179. As to planting peanuts, Mr. Bishop says: ‘
