Tlie results are slightly in favor oi plowing under 

 IH'avines in the latter part of the fall rather than in 

 spring. As the plots were not strictly uniform, further 

 experiments are needed before definite conclusions can 

 be drawn. It should be said that on July 5, 1899, the 

 foliage of the corn plant was much greener where the 

 vines had been turned under in the fall than on the other 

 idots, though the ears were not discernably different. 



It is usually regarded as best to avoid fall plowing 

 on sandy land in the South unless a winter crop is 

 to be grown. On heavy soils where fall plowing may 

 otherwise be desirable, the legumes should first be al- 

 lowed to mature. 



Unless otherwise stated the time of plowing under 

 cowpea and velvet bean vines referred to in this bulletin 

 is a few days or weeks before the planting of the new 

 crop that is to occupy the ground.

OF Cowpeas. 



Corn was grown in 1898 and 1901 immediately fol- 

 lowing different varieties of drilled cowpeas which had 

 been picked and in spring the vines plowed under.
