BESULTS AT DICKINSON." 



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

 ative experiments at Dickinson since they were begun in 1907. 

 Two selections from Kherson, Albion (Iowa No. 103) and Richland 

 (Iowa No. 105), were added to the experiments in 1916. The 

 annual and average yields of these and of ten other varieties of oats 

 grown at Dickinson for two or more years in the 11-year period from 

 1907 to 1917, inclusive, are presented in Table XXVIII. 



Table XXVIII. — Annual and average yields of the Kherson, Sixty-Day, and ten other 

 varieties of oats grown at the Dickinson (N. Dak.) substation during two or more years 

 in the 11-year period from 1907 to 1917, inclusive.

Only four varieties have been grown continuously since 1907. 

 Of these, Golden Rain, a midseason yellow variety, has yielded 

 best, with Kherson a close second. The materially lower yields of 

 the other two varieties, Banner and White Russian, are due to the 

 fact that hail destroyed the Banner in one year and the White Rus- 

 sian in two years, after the earlier varieties were harvested. The 

 Sixty-Day has averaged 2 bushels less than the Kherson in the years 

 both have been grown, but since 1910 it has averaged about 1 bushel 

 more. Several varieties have been grown continuously in the 7- 

 year period from 1911 to 1917, inclusive. In this period the Victory 

 has outyielded all others, with Golden Rain ranking a very close 

 second. Both these varieties are pure-line selections developed in 



oData from V. S. Department of Agriculture Bulletin .33 (11), and from annual reports of Mr. Ralph W. 

 Smith, scientific assistant in charge of cereal experiments at the Dickinson (N. Dak.) substation, to 

 the Office of Cereal Investigations.
