Kubanka wheat was one of the best yielding durum wheats. Its 

 quality for the manufacture of semolina and macaroni and its wide 

 distribution make it the best variety. Kubanka exceeded all durum 

 varieties except Nodak in yield. Its much better qualities make it 

 more valuable than Nodak. 



During the period 1926-32 Reliance, the best yielding variety of 

 hard red spring wheat, produced an average yield of 12.9 bushels per 

 acre. During the same period Kubanka, the highest yielding durum 

 wheat, produced an average yield of 14.2 bushels per acre. The dif- 

 ference in yield in favor of Kubanka was not proportionately so high 

 as the price difference in favor of hard red spring wheat. When 

 any great margin in price exists, it more than makes up for the 

 higher yield of durum wheat. 



OAT VARIETIES 



Comparative yields of oats are shown in table 12. Sixty-Day was 

 used as a standard for measuring other varieties.

i Calculated at 32 pounds to the bushel. 



Brunker was the outstanding variety of oats. During the 6-year 

 period this variety produced an average yield 4.2 bushels per acre 

 higher than Sixty-Day, and in dry years the grain was generally 

 of better quality. In the very dry years, 1931 and 1932, Brunker 

 was the only variety of oats that produced grain weighing more 

 than 32 pounds per bushel. 



Gopher oats were less productive than Brunker but were consider- 

 ably better than other varieties. During the 6-year period they pro- 

 duced an average yield of 28.5 bushels per acre. Three other varieties 

 of oats, Iowar, Burt X Sixty-Day, and Markton, produced yields 

 closely approaching each other but all lower than Gopher. Very lit-
