Mammoth (seeds, straw yellow). The latest maturing variety- 

 grown. A fairly satisfactory yield of green forage,, but does not 

 mature sufficiently to set many pods. The seed of this variety 

 is plentiful, however, and usually cheaper than that of other 

 varieties. 



Wilson (seeds, black). A fine-stemmed variety suitable for 

 hay when grown in rows, if seeded early and on- an early soil. 

 A very good yielder. 



Black Champion (seeds, black). Similar to the Wilson but 

 a few days later. 



Medium Yellow (seeds, straw yellow). An early maturing 

 variety. Forms an abundance of pods and seed here. It is very 

 branching and suitable for either silage or hay. 



Ito San (seeds, straw yellow). An early variety suitable for 

 hay or silage. Although it does not produce as much green 

 forage as some of the later maturing varieties, it is a good yielder, 

 of both dry matter and protein. Not so branching or fine 

 stemmed as the Medium Yellow. Will mature seed here if 

 planted by June 1. 



Manchu (seeds, straw yellow). An early variety very similar 

 to the Ito San. Will mature its seed here. 



Black Eyebrow (seeds, mottled black and yellow). A variety 

 similar in appearance to the Manchu and maturing a few days 

 later. Suitable for either hay or silage. Will also mature seed. 



Wisconsin Early Black (seeds, black). The earhest variety 

 we grew here. Suitable for hay or seed. Matures its seed in 

 about 100 days. 



OTHER USES OF THE SOY BEAN. 



As a soiling crop. On account of its high feeding value the 

 soy bean may be utilized as a soiling crop where such a system is 

 practised on the farm. If grown for soiling, the stems should be 

 kept fine the same as for hay, so that all of the forage will be 



eaten. 



As a seed crop. The four earher varieties described above 

 will mature seed and can be grown as a seed crop. We have made 

 no trials of their seed-producing capacity here but expect to do
