with the mower, the plants are gathered into windrows and then into 

 small cocks and allowed to cure. The use of the grain binder is very 

 satisfactory, the soy bean plants being formed into small bundles and 

 placed in open shocks. When cured, the beans may be threshed direct 

 from the shocks or put into stacks. They may be threshed through a 

 bean separator or through an ordinary grain separator, with the cylinder 

 running at half -speed, and the other mechanism running at the usual 

 speed. Small amounts can readily be beaten out with a flail. 



SUMMARY. 



Soy beans are grown for hay, with corn for ensilage and hogging-off, 

 for green manuring, as a protein concentrate, and a seed crop. 



Soy beans are adapted to all tj'pes of well-drained soils in sections 

 where the growing season is suited to the production of corn for grain. 



Soy beans frequently make considerable growth on light, sandy soils 

 that are so deficient in organic matter that alfalfa and red or June clover 

 fail. 



When planting soy beans in a field for the first time it is desirable 

 to inoculate. 



Selection of variety is very important, the Manchu, Ito San, Early 

 Brown, and Black Eyebrow being high yielders of grain and forage. 



Soy beans should be sown just after corn-planting time, from May 

 15th to June 15th. 



Soy beans should be planted shallow. For hay or as a green manur- 

 ing crop, either plant in rows 28 inches apart, using about 40 pounds 

 of seed per acre or in rows 7 inches apart, with grain drill, using from 

 six to eight pecks of seed per acre. For seed, plant in rows 28 inches 

 apart, using from 30 to 40 pounds of seed per acre. 



When planted with corn for ensilage better results are secured by 

 using a soy bean planting attachment on the corn planter. 



For hay, cut when the pods are well-formed and beginning to fill and 

 before the lower leaves turn yelloAV and drop off. 



For seed, allow pods to reach maturity, harvesting before shattering 

 stage is reached. 



Cowpeas are not as well adajtted to Michigan conditions as soy beans.
