Fertilizers were applied evenly broadcast on April 11. 

 The yields the past year are shown below : — 



Plot 1, "special" fertilizer: hay, 795 pounds; rowen, 130 

 pounds. 



Plot 2, fertilizer richer in potash: hay, 810 pounds; rowen, 

 129 pounds. 



Plot 3, "special" fertilizer: hay, 725 pounds; rowen, 97 

 pounds. 



Plot 4, fertilizer richer in potash: hay, 617 pounds; rowen, 

 165 pounds. 



The average yield on plots 1 and 3 is : hay, 760 pounds ; 

 rowen, 113|^ pounds. On plots 2 and 4 : hay, 7131 ; rowen, 

 147 pounds. Piitting the crops of hay and rowen together, 

 we have an average from 1 and 3 of 873^ pounds, and from 

 2 and 4 of 8601 pounds. The difference, 13 pounds, is 

 too small to be regarded as of much significance. The 

 greater rowen crop produced by plots 2 and 4 is perhaps 

 to be attributed to the larger amount of potash which has 

 been applied to these plots, which favors especially the 

 growth of the clovers. Inequality of moisture conditions, 

 however, has been the apparent cause of a very uneven 

 development of clover on different parts of the field, and 

 the influence of the potash does not show as clearly as 

 was anticipated.
