BULLETIN 222, TJ. S. DEPARTMENT OF AGRICULTURE. 



HETTINGER FIELD STATION. 



Results for three years have been obtained at Hettinger, N. Dak. 

 All were years of good barley yields. The highest yields were 

 obtained each year by summer tillage and the lowest, with one excep- 

 tion, on disked corn ground. The average yield from summer tillage 

 was more than twice that from the disked land. Following small 

 grain, a decided advantage attended spring-plowed barley stubble. 

 The crops in this group yielded better than on disked corn ground, 

 but not as good as by summer tillage.

The relative position assumed by the various methods may be due 

 in part to the distribution of the rainfall for the two years, 1911 and 

 1912, and may be changed with subsequent work. In both 1911 and 

 1912 a heavy rainfall came in August and September. The corn, 

 which was still growing, used this water, while a portion of it was 

 accumulated in the small-grain plats, where the grain was already 

 harvested, and in the summer-tilled plats The corn plats were
