EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
33 
on the average in the 5-year period from 1909 to 1913, inclusive. 
The Winter Turf from fall seeding also has exceeded the Kherson and 
Sixty-Day, even though one crop was entirely lost by winterkilling. 
Results in Kansas. 
The annual and average yields of the Sixty-Day, the Seventy-five 
Day, the Kherson, and seven other varieties of oats grown at 
McPherson, Kans. (12), in four or more years in the 6-year period 
from 1904 to 1909, inclusive, are shown in Table XXIII.

The data in Table XXIII show that the early yellow varieties 
considerably outyielded all others at McPherson. Their nearest 
competitor was the Georgia Rustproof, a strain of Red Rustproof. 
The Perm, a slightly later oat from a more northerly district in 
Russia, averaged about 3 bushels less than the Sixty-Day. The 
Seventy-five Day, which, as previously noted, probably is identical 
with the Sixty-Day, averaged 1 bushel less in a 4-year test. The 
Sixty-Day exceeded the midseason and late oats by about 50 per 
cent. 
Results in Northeastern Texas. 
Varietal experiments with Sixty-Day and several other varieties 
of oats were conducted by the Texas Agricultural Experiment Sta- 
tion at the Denton substation, near Denton, Tex. (13, p. 9-10), 
during 1912, 1913, and 1914. The results of these experiments are 
summarized in Table XXIV.
