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.
