BARLEY IN THE GREAT PLAINS AREA. 



19 



therefore short of available water when the barley was seeded and 

 consequently gave lower yields. Weeds were also a factor in decreas- 

 ing the yields on disked corn ground. 



A profit was realized from all methods under trial. Between fall 

 plowing, disking, and summer tillage there was little difference. 

 Spring plowing shows a considerably larger average profit than any 

 of the other methods. 



BELLE FOURCHE FIELD STATION. 



The results of six years at Belle Fourche, S. Dak., are available for 

 study. In only one year was the yield heavy. Three of those years 

 gave light yields from most methods; in one year the crop was a 

 total failure from all methods, and in the other year only one method 

 gave any yield and that was light.
