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 fu-st and third, 

 respectively, among 30 varieties grown. In the 7-year period from 

 1911 to 1917, mclusive, 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 tlurd, 

 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 Bome 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.

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
