rainfall, the yield was 28 bushels per acre. The yield of hay in both cases 

 was practically the same. 



The methods of seeding and harvesting for seed production are treated 

 in the foregoing chapter. 



Soy Beans. The growing of soy beans for gram to be used as feed is 

 profitable if the yield is sixteen bushels or more per acre. The seed is very 

 rich in oil and protein and occupies the same place in concentrates as 

 cottonseed meal and oil meal. The seed should be ground before being fed. 

 Some of the varieties with highest fat content are being utilized for the 

 manufacture of oil. This is used as a substitute for linseed oil in the manu-

This annual legume is excellent for both forage and seed production. May be 

 grown nearly as far north as dent corn. 



thirty to forty bushels of seed to the acre. Hollybrook, Mammoth and 

 Haberlandt are three especially good varieties for seed production. Tall 

 varieties that bear pods some distance from the ground are most desirable 

 and most easily harvested. 



The methods for harvesting and threshing are given in the preceding 

 chapter. The threshed beans should be thoroughly dried when stored. 

 Otherwise they are likely to heat and spoil. They should be carefully 

 watched when first stored and at once spread out to dry if there are signs of 

 heating. 



Soy bean seed is especially exempt from weevils.
