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. 1 
The Sixty-Day oat has been included in the varietal experiments 
at Williston 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.
