EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



45 



nESUI.TS AT EUREKA. 



Tho only two varieties which have been grown at the Eureka sub- 

 Station, as at Cottonwood, are the Sixty-Day and the Swedish Select. 

 These two varieties have been grown at that point continuously since 

 1909. Their annual and average yields in the 9-year period from 

 1909 to 1917, inclusive, arc shown in Table XXXIII. 



The results shown in Table XXXIII indicate that the Sixty-Day will 

 outyield the Swedish Select variety under conditions similar to 

 those at Eureka. The difForence between the 9-year average yields 

 of the two varieties is 4.8 bushels. 



RESULTS AT HIGHMORE. 



The Kierson and Sixty-Day oats have been included in the coopera- 

 tive Varietal experiments at Highmore since 1906. The annual and 

 average yields of these and five .other varieties of oats grown at High- 

 more in five or more years in the 12-year period from 1906 to 1917, 

 inclusive, are presented in Table XXXIV.

1 While very small jrields were obtained in 1912, they were not sufficient to pay for harvesting and are, there- 

 fore, not considered. 



Reference to Table XXXIV shows that the Sixty-Day has out- 

 yielded all other varieties at Highmore. The Kherson slightly ex- 

 ceeded it in average yield during the years it was grown, due to a wide 

 difference in the yields of the 1906 crop. Except in this year the 

 Sixty-Day usually has yielded more, and the Kherson has been dis- 

 carded. The 12-year average of the Sixty-Day is 6.2 bushels higher 

 Ihan that of the Swedish Select, the highest yielding midseason white 

 variety.
