36 BULLETIN 270, TJ. S. DEPARTMENT OF AGEICTJLTUEE. 



39.9 bushels, has been produced by the WiUiston No. 170 (C. I. No. 

 882), a strain of Manchuria barley. 



Flax is grown with some difficulty on ground that is infested with 

 weeds. In the seven years that tests were made, only four crops 

 were harvested. The average yield of the highest producing variety 

 for these four years was 16.2 bushels per acre from the North Dakota 

 No. 1221 (C. I. No. 16). 



Emmer and spring rye have not given as high average yields as 

 oats, barley, or wheat. 



Proso, grown in field plats from 1912 to 1914, inclusive, gave an 

 average yield of seed per acre of 25 bushels. Kursk millet, grown 

 in a plat test in 1914, yielded 38 bushels of seed per acre.
