the Kherson has outyielded the best Sixty-Day strain by about 3 

 bushels and Colorado No. 37, the best of the midseason white varie- 

 ties at Akron, by 7 bushels. 



Table XXXVII. — Annual and average yields of the Kherson, the Richland, the Albion, 

 two strains of the Sixty-Day, and five other varieties of oats grown at the Akron (Colo.)

The Tartarian, a late white side oat, has an average yield of only 

 26.5 bushels for the same period, as compared with Burt, Kherson, 

 Colorado No. 37, and Swedish Select, with 42.7, 42.3, 35.3, and 32.7 

 bushels, respectively. Early Champion, grown in 1908, 1909, and 

 1910 only, averaged 7 bushels to the acre less than Kherson in the 

 same years. 



Conclusions. 



The average yield of the leading variety in each group at the 

 stations included in the northern Great Plains is shown graphically 

 in figure 11. 



Except at the higher elevations in the northern Great Plains and 

 in the extreme north, Sixty-Day and Kherson oats usually yield 

 better than other varieties. 



At the Judith Basin substation, in central Montana, Sixty-Day 

 and Kherson oats have yielded slightly better than the midseason 

 varieties. 



At the Edgeley substation, in southeastern North Dakota, the 

 Sixty-Day oat has yielded about the same as the best midseason 

 varieties, but at other stations in the central and western portions 

 of North Dakota, midseason varijeties, such as Victory, Golden Rain, 

 and Silvermine,.have yielded considerably better than the early oats.
