EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
51 
Results at Hays, Kans. 1 
The Kherson and Sixty-Day varieties have been included in the 
experiments conducted at the Hays (Kans.) Branch Experiment Sta- 
tion since 1908, but comparable data are available from these experi- 
ments only since 1913. The annual and average yields of these and 
of two other varieties of oats grown at Hays during the four years 
from 1913 to 1916, inclusive, are given in Table XXXIX.

It will be noted from Table XXXIX that very poor yields were 
obtained at Hays; in fact, so poor that the crop is evidently not a 
profitable one. From the few data shown it appears that the Burt 
will outyield the Kherson and Sixty-Day in this section. The best 
yield at the station was produced by a Burt X Sixty-Day hybrid 
which is not yet commercially grown. 
Results at Amarillo, Tex. 2 
The Kherson, the Sixty-Day, and the Seventy-five Day oats all 
have been included in the varietal experiments at Amarillo since 1906. 
Several selections of the Sixty-Day variety also have been included 
for shorter periods. The annual and average yields of these strains 
and of six other varieties and selections are shown in Table XL. 
The data shown in Table XL indicate that the early red varieties, 
Red Algerian, Red Rustproof, and Burt, at Amarillo outyield the 
Kherson and Sixty-Day on the average from 2 to 4 bushels per acre. 
The average yield of the best red strain in the eleven years from 1906 
to 1916, inclusive, is 20.6 bushels, compared with 18.9 bushels for
