EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



39 



Neither the Albion nor Richland, the two selections from Kherson, has 

 yielded so well in the two years in which they have been tested as 

 the original Kherson and Sixty-Day. 



Results in North Dakota. 



RESULTS AT WILLISTON.' 



The Sixty-Day oat has been included in the rarietal experiments 

 at Willis ton since 1908, while the Kherson has been grown only 

 since 1914. Two selections from Kherson, Albion (Iowa No. 103) 

 and Richland (Iowa No. 105), were added to the tests in 1916. The 

 annual and average yields of these and six other varieties which 

 have been grown three or more years in the 10-year period from 

 1908 to 1917, inclusive, are presented in Table XXVII.

The results given in Table XXVII show that the Sixty-Day and 

 Kherson do not yield nearly as well at Williston as the later or mid- 

 season varieties. The best of the midseason white varieties have 

 decidedly outyielded the Kherson and Sixty-Day and therefore are 

 to be recommended. In the 10-year period from 1908 to 1917, 

 inclusive, the four highest yielding varieties of this group, viz, Abun- 

 dance, Lincoln, Silvermine, and Siberian, have averaged 71.5, 70.8, 

 69.5, and 68.6 bushels, respectively, as compared with 50.6 bushels 

 for the Sixty-Day. A strain of the White Russian, a late side oat, 

 has also outyielded the Sixty-Day by about 11 bushels.

 F. Ray Babcock, formerly scientific assistant in charge of cereal experiments at the Williston sub- 

 station, to the Office of Cereal Investigations.
