EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS.

investigations. In a letter dated December 11, 1917, he states that 
of 27 varieties grown during the seven years from 1911 to 1917 the 
Kherson ranks sixth and the Sixty-Day eighth. In the three years 
1915, 1916, and 1917, however, these varieties rank first and third, 
respectively, among 30 varieties grown. In the 7-year period from 
1911 to 1917, inclusive, the Fourth of July ranks first, with an average 
yield of 64.6 bushels to the acre. In the same period the Kherson 
averaged 63.0 and the Sixty-Day 62.2 bushels. In the three years, 
1915, 1916, and 1917, Kherson ranks first, with an average yield of 
78.4 bushels; New Zealand second, 75.9 bushels; Sixty-Day third, 
75.8 bushels; and Fourth of July fourth, 75.7 bushels. In yield of 
straw the Kherson and Sixty-Day are consistently lowest of all, a 
characteristic which leads Prof. Noll to remark: 
In some sections where little or no wheat is grown and straw is relatively valuable 
we find these varieties objected to on account of their rather low yields of straw.

of oats grown at the Pennsylvania Agricultural Experiment Station (at State College) 
during two or more years in the 4-year period from 1907 to 1910, inclusive.

* Probably identical with Irish Victor. 
Prof. Noll further states that where oats are sold the Sixty-Day 
and Kherson are objected to because of the small size and yellow 
color of their grain. 
Conclusions. 
The average yield of the leading variety in each group, at the sta- 
tions included in the North Atlantic States, is shown graphically 
in figure 3. 
The data presented in Tables II and III indicate that under New 
England conditions the midseason varieties will outyield the Kherson 
and the Sixty-Day. In Maine such varieties as Banner, Prosperity, 
and Irish Victor have averaged several bushels more than the Kherson
