A STUDY OF SOY BEANS 107 



great many broken seed. The broken grains are not fit for 

 seed, therefore, a sample which contains a large number 

 of broken seed has its value for seeding purposes much re- 

 duced. Both purity and condition should be taken into 

 consideration in determining the value of a given sample 

 for seed purpose. 



Some varieties of soy beans have been given names 

 which indicate the length of the growing season required 

 for their development and the color of the bean. For 

 example we have such varieties as medium yellow, medium 

 green and mammoth yellow. When harvested for seed 

 the soy bean must be cut before the pods are dry, other- 

 wise they shatter badly and a large percentage of the beans 

 will be lost in the handling before the crop gets to the 

 thresher.
