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 Xo. 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 Xorth 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 Xorth Dakota, midseason varieties, such as Victory, Golden Rain, 
and Silvermine, have yielded considerably better than the early oats.
