of the former to a half bushel of the latter per acre should be used. 

 If planted in rows, about one-half of this quantity of each is suffi- 

 cient. It is necessary to have more soy-bean plants than cowpeas, so 

 that the vining growth of the cowpeas may be supported properly. 

 The Mammoth and Hollybrook varieties of soy beans are preferable. 

 The Whippoorwill and Iron varieties of cowpeas are good. 



Soy Beans and Sorgo. The soy bean may be grown in mix- 

 ture with sorgo (sweet sorghum). There is some objection to the 

 mixture when broadcasted, as the sorgo is apt to choke out the soy 

 beans. When grown together in cultivated rows, this objection is 

 largely overcome. Amber sorgo is usually the best variety for use. 



Soy Beans and Millet. Some of the earlier varieties of soy beang 

 have been grown with German millet. The mixture is not a good 

 one, as the millet matures long before the soy beans. 



Soy Beans and Corn. Soy beans are more commonly grown 

 with corn than with any other crop. They are planted in different 

 sections in various ways, namely, in alternate hills with the corn in 

 the same row, in alternate rows of each, in alternate series of two 

 rows of each, or broadcasted in mixture. Such fields when planted 

 in rows may be harvested for silage, or where the rows alternate 

 the two crops may be harvested separately. Sometimes such mixed 

 fields are utilized by pasturing to hogs. The early and medium 

 varieties of soy beans may be planted in between the corn rows at 

 the time of the last cultivation. 



Soy Beans for Ensilage. The growing of soy beans for ensilage 

 has not been practiced very extensively. In a number of instances 

 ensilage has been made of the crop, usually in combination with corn, 

 and it is invariably reported as making an excellent succulent feed. 

 Only the larger late-growing varieties are desirable for this purpose. 

 Some have tried growing soy beans in the corn rows or between the 

 , corn rows, planting it the same as cowpeas are planted in the corn- 

 fields of the South, while others prefer growing corn and soy beans in 

 separate fields and when the ensilage is put up to mix them in the 

 cutting. Where the soil and climate will permit, it would seem to be 

 more satisfactory to grow the soy beans in the cornfield. It is doubt- 

 ful whether it will be economical to make ensilage of soy beans when 

 hay can be made with comparative ease. 



Soy Beans for Grain. Growing soy beans for the grain for use 

 as feed is distinctly profitable if the yield is 16 bushels or more per 

 acre. The feeding value of the grain is very high, being slightly su- 

 perior to cotton-seed meal. The grain is rich in protein, while nearly 

 all the other grains produced on the farm are poor in protein, but 

 rich in carbohydrates. For grain production tall varieties that do 

 not branch or bear pods close to the ground are desirable, as they 

 are more easily harvested. Of the varieties now on the market the 

 Mammoth and Hollybrook are undoubtedly much the best for the 

 South, while the Ito San and the Guelph, which is also known to tho 

 trade as Medium Green, are best for more northerly latitudes. A 

 very serious objection to the Guelph, however, is its great tendency 

 to shatter seeds at ripening time. When grown for grain alone, the
