The yields produced were the highest ever recorded at the station. 

 Figure 6 shows the winter-wheat varieties grown in rephcated fiftieth- 

 acre plats in 1915. 



In the fall of 1912 and of each succeeding year the seven leading 

 varieties of winter wheat were seeded on acre plats. This change 

 was made in order to test these varieties on a large scale under 

 actual field conditions and to have seed of the best varieties available 

 for distribution. Table XI gives the annual and average yields of 

 these seven varieties on acre plats in the three years, 1913, 1914, and 

 1915. The land where these varieties were grown was not always 

 in the best of tilth. The plan was to give the land only such cultiva-

tion as it would receive under average farm conditions. The yields 

 from the acre plats were not as high as the yields of the same varieties 

 grown in the smaller plats.
