EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
25 
give fairly good results in quite a wide range of seasons. I consider them one of the 
best varieties for this region. From the standpoint of distributing the harvest 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. 1 
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.

3 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. 
1 Data obtained cooperatively by the South Dakota station and the Bureau of Plant Industry. The 
data previous to 1912 were published by the United States Department of Agriculture (10).
