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.
