good culture. In each case the grain was carefully 

 harvested and weighed, and in the table is recorded 

 the actual weight of grain or seed not including the 

 weight of husks, cowpeas and soy bean hulls.

In the column of averages it is noticed that the 

 pounds of shelled corn per acre more than doubles 

 the pounds of soy beans or cowpeas. If the legumes 

 are grown only for their grain, their jdeld does not 

 compare favorably with corn as a grain crop. 



The analysis of the soy bean grain shows that it has 

 about four times as much digestible protein, one-third 

 as much carbohydrates, and over three times as much 

 fat as corn grain. Soy beans or soy bean meal, fed as a 

 supplement with corn to growing stock or those requir- 

 ing a high protein ration, produce a gain about equal to 

 that obtained from the feeding of equal amounts of 

 shorts, tankage or cottonseed meal in combination with 

 grain. For dairy cattle, ground soy beans show a slightly 

 higher feeding value than cotton seed meal.* In feed- 

 ing ex])erimcnts of fattening hogs, soy beans supple- 

 mented with corn gave about the same gain that was 

 secured from feeding tankage and corn."* 



When one considers the fertilizing effect of a crop of 

 soy beans on the land for any following crop, and the 

 ease with which the crop is grown and the high feeding 

 value of the bean as a concentrated feed, the true value 

 of the corn and the bean crop to the farmer may be 

 seou in its real light. 



F2NEMIES OE THE SOY BeAN 



Probably Ihe greatest enemy to the growing of the 

 soy bean is rabbits. They are very fond of the young, 

 green, tender foliage. Where only a small patch is 

 planted, the rabbit has been known to destroy it entire- 

 ly. It is suggested that the farmer plant enough for the 

 rabbits and for the farm.
