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 Russian varieties by 3, 
2.9, 9.1, and 11.5 bushels, respectively. 
i Data obtained cooperatively by the South Dakota station and the Bureau of Plant Industry. Data 
previous to 1914 were published in U. S. Department of Agriculture Bulletin 39 (10); in South Dakota 
Agricultural Experiment Station Bulletin 149 (17), and in TJ. S. Department of Agriculture Bulletin 297 
(32).
