The Soybean.--The soybean is gaining a place among the valuable legumes of the United States, and the acreage is increasing as its merits become known to all. Its northern limits of profitable production are much farther north than those of the cowpea, and approach those of corn. In the south it is gaining friends. Some of the advantages of the soybean over the cowpea, as found by the Tennessee station, may be stated as follows: 1. Greater seed production in case of fertile soils. 2. Less sensitiveness to cold in spring and fall. 3. Greater feeding value of the seed. On the other hand, a stand of cowpea plants is surer in the case of soils that crust, and germination runs higher. Its climbing habit makes it better suited for growing with corn for forage. A less amount of leaves is lost in curing. Fertility Value.--There are so many varieties of the soybean and the cowpea, and adaptation to soil and climate varies so widely, that a fair comparison is difficult to make. In cool latitudes the soybean is recognized as distinctly more profitable, making larger yields of vines and of seed. Where adaptation is equal, the cowpea makes a slightly larger growth of vines for hay, but the soybean gives a much richer lot of seed for use as grain. When soil fertility is the chief consideration, the adaptation of climate and soil should decide our choice between these two legumes. There is no serious difference where conditions for each are equally good. In cool latitudes the soybean should be chosen. In the Ohio Valley it is usually to be preferred. The greater part of the organic matter and the plant-food is stored in the vines and seed. Feeding Value.--The soybean makes a rich hay, surpassing clover, but it is coarse, and its unattractive appearance has caused many farmers to condemn it without trial. Livestock eat it greedily, and it is one of our richest coarse feeds. The curing is more difficult than in the case of the cowpea because the leaves drop early, and the plants must be harvested before they approach maturity. Probably the large yield of rich seed is the most important feature of the soybean crop. A ton of the seed contains as much protein as a ton of old-process oil meal, and three fourths as much as a ton of cottonseed meal. A good crop of the soybean will yield 18 to 20 bushels of seed, and as the nitrogen may be obtained chiefly from the air, the protein from this crop will come to be a leading substitute for purchased protein feeds.
