EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



51 



Results at Hays, Kans.i 



The Elherson 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.

 and oftivo other varieties of oats grown at the Hays (Kans.) Branch Experiment Station

1 A commercial lot of Burt; not a pure line. 



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 Blherson 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.^ 



The Klierson, 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
