CORN IN THE GREAT PLAINS AREA. 



19 



BELLE FOURCHE FIELD STATION. 



Table X presents the results of the work of six years with corn in 

 rotations and under varying tillage methods at Belle Fourche, S. 

 Dak. In one year, 1911, extreme drought caused a failure of all 

 methods under trial. In three of the six years grain was produced by 

 all methods. In the other two years all methods produced fodder, 

 but grain was produced only upon land which was summer tilled the 

 previous year.

Corn after corn produced more grain and more stover than corn 

 after small grain. Little difference is shown in the yields by spring 

 plowing and by fall plowing. Each of these methods has been tried 

 after both corn and small grain. 



Subsoiling was practiced on land continuously cropped to corn. It 

 produced yields practically the same as similarly cropped land plowed 

 either in the spring or fall without subsoiling. 



Planting with the lister on land continuously cropped to corn pro- 

 duced yields practically the same as those from corn ground plowed 

 and surface planted. 



The highest average yield of grain has been from land summer 

 tilled the previous year. The increase in the average comes chiefly 

 from the grain produced in 1910 and 1914, when other methods 

 failed, and to its increase of yield over other methods in 1913. The 

 yield of stover from this method does not show an increase over that 

 following the several methods by which corn is grown following corn.
