EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



25 



give fairly good results in (juite a wide range of seasons. I consider them one of the 

 best varieties for this region. From the standpoint of distributing theTiarvest season 

 over a longer period it might be wise to grow some of the midseason varieties as well as 

 the Sixty-Day oats on the farms of the Red River Valley, but I think that Sixty-Day 

 or Kherson can be grown on a very large percentage of the farms with profit. 



Results in Eastern South Dakota. > 



The annual and average yields of the Sixty-Day and six other 

 varieties of oats grown by the South Dakota Agricultural Experi- 

 ment Station in cooperation with the United States Department of 

 Agriculture at Brookings are given in Table XVI. Data are avail- 

 able for the 14 years from 1904 to 1917, inclusive.

 seven or more years in the 14-year period from 1904 to 1917, inclusive.

8 The variety is incorrectly named, as the true Wideawake is not a side oat. 



The data presented in Table XVI show that the early yellow 

 variety Sixty-Day has outclassed all other varieties at Brookings. 

 Its nearest competitor has been the Swedish Select, but the 14-year 

 average yield of this variety has fallen 10 bushels below that of the 

 Sixty-Day, the average yields being 58.1 and 47.9 bushels, respec- 

 tively. The Banner, a popular old variety, has been exceeded in 

 yield by the Sixty-Day in seven of the eleven years in which both 

 were grown. In seven years (1905-1911) the average yield of the 

 Sixty-Day (45.7 bushels) was more than double that of the ^White 

 Tartar (20.7 bushels), a late side oat. 



' Data obtained cooperatively by the South Dakota station and the Bureau of Plant Indtistry. The 

 data previous to 1912 were published by the United States Department of Agriculture (10).
