EFFECT OF DIFFERENT METHODS AND TIME OF APPLICATION OF 



FERTILIZER. 



The results presented in Table VII were obtained from tests 

 planned to show the effect on the yield of corn and stover from 

 applying— 



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



(b) Dividing the fertilizer into two eqnal 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 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 fer- 

 tilizer 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 as a side dressing around July first, ac- 

 cording to season. The average yield and profit from the broadcast 

 application of fertilizer were 22 per cent less than was produced by 

 the same quantity of fertilizer when apjilied in either of the two 

 wa^'s given above. The amount of fertilizer used in the test was 

 300 pounds, and it is quite clear that the best and most economical 

 way of using this amount of fertilizer per acre is in the drill before 

 planting the crop. Larger quantities might give as good or better 

 results broadcast or when applied at different times, and' on a dif- 

 ferent character of soil the results might be different.
