EESXJLTS AT BURNS. 1 



The Kherson and Sixty-Day oats have been included in the coop- 

 erative varietal experiments at Burns since they were begun in 1913. 

 Two selections of the Sixty-Day variety have been grown since 1913, 

 and an additional one since 1914. The annual and average yields 

 of these and of three other varieties which have been grown during 

 the 5-year period from 1913 to 1917, inclusive, are presented in 

 Table XLIV.

A selection from a variety at the Iowa station known as Rustless, 

 Iowa No. 444 and C. I. No. 724, somewhat similar to Silvermine, 

 has been the highest yielder in the 5-year period at Burns, with an 

 average yield of 34.2 bushels, compared with 31.0, 30.7, 30.1, and 

 24.6 bushels from Silvermine, Kherson, Sixty-Day (C. I. No. 625), 

 and Swedish Select, respectively. 



While these experiments have not been of sufficient duration to 

 warrant definite conclusions, indications are that the Silvermine 

 type is slightly better than the Sixty-Day to grow in the Harney 

 VaUey, except where early maturity is a distinct advantage.

The Kherson and Sixty-Day oats have been included in the coop-
