RESULTS AT NEWELL. 



The original strains of Kherson and Sixty-Day oats have been in- 

 cluded in the varietal experiments at Newell since 1908. In 1910 

 two selections of the Sixty-Day were added and in 1912 two more of 

 the same variety. These have been continued to date, except that 

 one of the selections was not grown in 1916 and 1917. In addition, 

 the strain known as Seventy-five Day was included for several years. 

 Aside from the early yellow strains, seven other varieties have been 

 grown in four or more years in the 9-year period from 1908 to 1916, 

 nclusive. The annual and average yields of the leading selections 

 and varieties grown at Newell are presented in Table XXXII. 



The data given in Table XXXII indicate that the early yellow 

 varieties, Kherson and Sixty-Day, are the most dependable for west- 

 ern South Dakota. The average yield of the Kherson in the 10-year 

 period from 1908 to 1917, inclusive, is 31.6 bushels, compared with 

 26 and 22.7 bushels from Swedish Select and White Russian, respec- 

 tively. In the 6-year period from 1912 to 1917, inclusive, a white- 

 kerneled selection of Sixty-Day, C. I. No. 626, has outyielded the 

 Kherson, Burt, Swedish Select, and White Kussian varieties by 3, 

 2.9, 9.1, and 11.5 bushels, respectively.
