EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



57 



two selections from the Kherson, and seven other varieties and selec- 

 tions of oats have been grown at Moro for two or more years in the 

 7-year period from 1911 to 1017, inclusive. The annual and average 

 yields of these are presented in Table XLV.

The results at Moro, as shown in Table XLV, are similar to those 

 obtained at Bums. They indicate that there is little choice be- 

 tween the early yellow and the midseason white varieties for growing 

 in the Columbia Basin. The five varieties which have been grown 

 during the entire 7-year period are Siberian, Kherson, Sixty-Day, 

 Swedish Select, and Canadian, with average yields of 49.2, 48.7, 48.6, 

 44.3, and 41.9 bushels, respectively. In the 4-year period, 1914 to 

 1917, inclusive, a selection from Sixty-Day, 165-1, leads with an 

 average yield of 60.1 bushels, which is 4.1 bushels higher than that 

 of the Siberian, the best midseason variety, and 1.6 bushels higher 

 than that of the original Sixty-Day. The earlier maturity of the 

 Kherson and Sixty-Day varieties also must be taken into considera- 

 tion, as earliness is frequently a decided advantage in this section of 

 the country.

RESULTS AT PULLMAN. 



The annual and average yields of the Sixty-Day and four other 

 varieties of oats grown at the Washington Agricultural Experiment 

 Station at Pullman (33) in 1914 and 1915 are shown in Table XLVI.
