Fig, 15.— Diagram showing the average yields, in bushels per acre, of the highest yielding variety of each 

 of several groups of oats under irrigated conditions at four agricultural experiment stations in the northern 

 Great Plains and western basin areas during the periods of years indicated. 



SUMMARY OF DATA. 



The name and average yield of the highest yielding variety of early 

 oats grown under humid, subhumid, semiarid, or irrigated conditions, 

 at each of the 48 stations discussed in this bulletin, are shown in 

 Table LV. In parallel columns also are presented the names and 

 average yields of the highest yielding midseason and late varieties, 

 which were grown at the stations in the same period of years except 

 where otherwise indicated. The length of the periods is indicated 

 in the second column.
