AMARILLO FIELD STATION. 
The results with barley at Amarillo, Tex., have been tabulated for 
six years; 1910 is not included, owing to the necessity of changing the 
location of the farm. The crop of that year was the first from 
prairie sod and was raised on land uniform in its preparation for all 
plats. While there was some growth of straw, a crop of grain did 
not mature. Three of the six years under study were productive of 
much better average yields than the other three. During two years 
the crop was practically a failure by all methods. In the remaining 
year one method, summer tillage, gave a yield of 17.5 bushels per 
acre, while most of the other methods were failures. On the average, 
there appears to have been no increase in yields from subsoiling, from 
listing instead of plowing, or from raising the barley on disked corn 
ground.
