Yield of Corn and Stover jyer Acre. 



The yield on the three no-nitrogen idiots (4, 7 and 9) is 

 much inferior to that on any of the others, although it is 

 still almost equal to the average rate of yield of corn per 

 acre in this State. The yield on all the plots receiving nitro- 

 gen was good, but wide differences will be noticed. The 

 plot to which manure was applied gave a yield much supe- 

 rior to that obtained on any of the other plots. The relative 

 rank of the manure plot with most of the crops grown has 

 been much lower. In corn, as is well understood, we have a 

 crop capable, in unusual degi-ee, of utilizing the nitrogen of 

 our coarser manures, since its principal growth occurs at a 

 season sufficiently late so that the nitrogen of the compara- 

 tively inert organic compounds of the manure can previously 

 have been rendered available by the natural processes of 

 decay and nitrification, for which the warm weather of the 

 early and mid-summer months is so favorable. 



The average yields of this year on the several fertilizers 

 are sho^\^l in the following table : —
