Effect of Different Methods and Time of Application of 



Fertilizer. 



The results presented in Table VII were obtained from experiments 

 planned to show the effect on yield of seed cotton from applying — 



(a) All the fertilizer in the drill before planting; 



(h) Dividing the fertilizer into two equal parts, applying one-half in 

 the drill before planting and the other half as a side dressing about 

 July first; and 



(c). From applying all of the fertilizer broadcast before planting, the 

 quantity of fertilizer and the materials entering into it being the same 

 in all three cases. 



Taking the results as a whole, the increased yields and profits show 

 that it has made very little difference whether all of the fertilizer was 

 applied in the drill before planting, or whether it was divided into two 

 equal parts and one-half put in the drill before planting and the other 

 half applied as a side dressing about July first, according to season. The 

 double application gave the largest yield and profit, the drill application 

 before planting slightly less, and the broadcast application a still smaller 

 yield and profit. These differences are hardly sufficient to warrant any 

 definite conclusions in favor of one method above another.
