Dwarf and Ckisler Habits of Some Varieties 



The early varieties are dwarf in habit of growtli, 

 Avoody, and hard to harvest. The percentage of straw 

 to beans is, in some dwaif varieties, less than 50; in 

 the larger varieties it ranges from GO to 75 per cent. 

 The straw of dwarf varieties is not eaten closely by 

 stock on account of its hard, woody nature. 



The yield of seed from 28 strains and varieties fell 

 50 per cent below that of Mannnoth Yellow; only four 

 strains came within 25 per cent of Mammoth Yellow; 

 none equalled it. From the standpoint of yield of 

 seed and straw or hay, only four or five varieties offer 

 any promise. They are being tested further. 



In per cent of fat, many of the low yielding varieties 

 and strains compare favorably with Mammotli Yellow. 

 Fourteen varieties contain more protein than Mannnoth 

 Yellow. The protein content ranges from 29.9 in No. 

 35622 to 40.25 per cenj in 37047. 



Soy Beans for Hay 



The soy bean makes an excellent hay when harves- 

 ted at the proper lime. Its feeding value seems to be 

 equal to that of alfalfa and cowpea hay. The average 

 of 23 analyses shows that it contains 16 per cent crude 

 protein, 24.9 per cent fiber, 39.1 per cent nitrogen-free 

 extract, and 2.8 per cent fat.* When used for this pur- 

 pose, it should be cut after the ])ods begin to form, 

 and before thev are fullv i*iown. If the cuttina" is
