HATCH EXPERIMENT STATION. 



[Jan. 



The crop of the past two seasons has been corn, the crop 

 of 1903 being the first to follo^y mixed grass and clover, 

 which occupied the land in 1901 and 1902. The season of 

 1904, while too low in average temperature for the best 

 growth of corn, was distinctly more favorable to tlie crop 

 than 1903. Tlie following tables sliow the yields on the 

 several plots and the averages for the two systems of ma- 

 nuring : —

It will be seen that the yields under the two systems of 

 fertilization were substantially equal, although the grain on 

 plots 1 and 3 was better ripened than on the other plots. 

 During the early part of the season the growth of the corn 

 on plots 1 and 3 was materially better than on plots 2 and 4 ; 

 the plants showed a better color and were of larger size. 

 This difference showed itself very early in the season. On 

 July 6, it was judged that the plants on plots 1 and 3 aver- 

 aged one and one-half times the height of the plants on the 

 other plots, and the difference in the growth on that date 

 was judged to be considerably less than at an earlier period. 

 As the season advanced, the corn on ]>lots 2 and 4 steadily 

 gained in condition and size, as compared with that on plots 

 1 and 3 ; and by the end of the season, as the harvest 

 showed, the initial superiority on })l()ts 1 and 3 had entirely 

 disappeared. At present we are not in a position to state
