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

Fig. 12. — Diagram showing the average yields, in bushels per acre, of 
the highest yielding variety of each of several groups of oats at two 
agricultural experiment stations in the southern Great Plains area 
during the periods of years indicated. 
The data obtained 
at both Hays, Kans., 
and Amarillo, Tex., 
show that the early 
red varieties. Burt, 
Red Rustproof, raid 
Red Algerian, are 
the best to grow in 
the southern Great 
Plains area. TTLiile 
the yields of the Kherson and Sixty-Day have been somewhat lower 
than those of the Burt and Red Rustproof, they doubtless are the 
next best varieties to grow. 
RESULTS IN THE WESTERN BASIN AND COAST AREAS. 
The western basin and coast areas include that portion of the' 
United States lying west of the Rocky Mountains. The growing of 
oats and other small grains in this region is confined mostly to the less 
arid districts. The results of experiments under irrigation are 
reported in another section of this bulletin. The principal grain-
