EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS.

on the average in the 5-year ])eriod from 1909 to 19 J. '^, 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.

4 Yield not comparable. 



The data in Table XXIII shoAV that the early yellow varieties 

 considerably outyielded all others at McPherson. Their nearest 

 competitor was the Georgia Kustproof, 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 vSixty-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.
