The maximum average yield of grain and of straw^ 

 came from seeding five pecks per acre. It is noticed! 

 that the j'ield of grain from three pecks was greater 

 than from four pecks and nearly as much as from five 

 pecks per acre. The usual rate when drilled and culti- 

 vated for grain is from two to three pecks per acre. 



The plants of the thick seeded plots stood up better^ 

 than those of the thin seeded plots. This is an impor- 

 tant consideration if the seed is harvested with 

 machinery. 



When soy beans alone are sown broadcast for hay, 

 the usual rate of seeding is from one to two bushels per 

 acre; when they are sown in combination with cowpeas 

 the usual rate is one bushel of peas and one of beans. 

 From the experiments that are recorded on page 111 

 the yield of hay can be increased, and its quality greatly 

 improved by increasing the above rate of seeding. 



Tillage 



The same implements used for cultivation of cottoir 

 can be used for cultivating soy beans. If the rows are 

 uniform in width, a "Gee Whiz" cultivator may be 

 used to make one trip to the middle while the plants- 

 are small; later cultivations can be made with scooter 

 and scrape. The crop should receive frequent shajlow 

 cultivation till the plants begin to bloom. 



Harvesting Soy Beans 



The time to cut for seed is when most pods are ripe- 

 and some leaves have fallen, just before the pods begin 

 to burst and scatter the beans on the ground. If the 

 pods are left on the plants to get completely ripe, the
