When 64 pounds of soy beans was planted in the 

 drill and cultivated two or three times, the yield of 

 hay was 1368 pounds per acre; when 61 pounds of Iron 

 cowpeas was planted in the same way and given the 

 same treatment, the yield of hay was 2970 pounds per 

 acre; but when 48 pounds of soy beans was mixed with 

 the same amount of Iron cowpeas and planted together, 

 the average yield of hay was only 2315 pounds per acre. 



When the rate of seeding soy beans is reduced to 

 about one bushel per acre, a wide difference in yield 

 between soy beans and cowpeas is observed. The 

 average yield of hay from 64 pounds of Iron cowpeas 

 per acre was greater by 1294 pounds than from the 

 same amount of soy beans. When planted in drill and 

 given two cultivations, the cowpeas exceeded the soy 

 beans by an average of 1602 pounds. 



Cowpeas, being a vine plant, covered the ground and 

 choked out grass and weeds, while the soy beans, being 

 an erect plant, permitted the grass and weeds to grow 

 and was itself choked by them. To secure the maxi- 

 mum yield and quality of hay from soy beans, the 

 seeding must be on good soil and sufficiently thick to 

 keep down weeds. 



The advantage of drilling soy beans for hay comes 

 from freedom of weeds and an improved quality of 

 hay. On strong land the same results to some degree 

 are secured from thick, broadcast seeding of beans.
