CORN IN THE GREAT PLAINS AREA. 

 DICKINSON FIELD STATION. 



17 



Table VIII shows the results of a study of the production of corn 

 at Dickinson, N. Dak., for six years, exclusive of 1912, when the crop 

 was destroyed by hail. Four of these years were productive of 

 grain, but in the other two years fodder only was produced.

The point most emphasized in a comparison of the yields by differ- 

 ent methods is the decreased production attending the growth of 

 corn on summer-tilled land. The only year when yields by summer 

 tillage have compared favorably with those by other methods was in 

 1911. This was the driest year in the series shown. Corn has not 

 generally suffered from a lack of water at this station. No signifi- 

 cance attaches to the small differences to be noted between the 

 yields of corn following corn and of corn following small grains. 



By all methods except summer tillage the grain crop alone has been 

 sufficient to afford a small profit. On summer-tilled land the crop 

 has been grown at an average loss of $2.92 when the value of both 

 grain and stover is considered. In the average of the six years under 

 study, spring plowing has given somewhat better returns than fall 

 plowing. The difference is not great enough, however, to be of much 

 practical importance. 



EDGELEY FIELD STATION. 



The results of eight years at Edgeley, N. Dak., are presented in 

 Table IX. In three of these years mature grain has been produced. 

 In two other years there were prospects for a good crop of grain, but
