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.
