HAYS FIELD STATION. 



Table XIV presents some of the results of different methods of 

 growing corn at Hays, Kans. The data are presented for only six 

 years. In 1911 and 1913, for which no figures are given in the table, 

 there would have been yields of forage, but the crop while suffering 

 from drought was destroyed by grasshoppers. The area of the plats 

 was so small that the damage from the insects was much worse than 

 it would have been on larger fields. The surrounding area is cropped 

 chiefly to small grains. When these are harvested, the grasshoppers 

 move from the stubble into the corn and sorghums. 



Corn produced an average of a little over lh tons of fodder and 5.5 

 to 9.9 bushels of grain per acre. Little difference is exhibited in the 

 yields by different methods. Such differences as are shown are not 

 consistent from year to year. While the crop is productive of a good 

 amount of feed each year, it appears to offer little possibility as a 

 grain crop. With values as here assigned to the grain and forage 

 the crop shows a small profit from all methods except summer tillage, 

 which is charged with an average loss of 54 cents per acre. The 

 greatest profits were by listing after corn and by spring plowing after 

 corn. These show average annual profits of $2.69 and $2.67 per 

 acre, respectively.
