The Kherson and Sixty-Day varieties have been included in the 
cooperative varietal experiments on the Judith Basin substation at 
Moccasin, Mont., since work was begun there in 1908. A selection of 
the Sixty-Day was added in 1910. The following year two more 
selections of the same variety were included, and in 1916 two selec- 
tions from Kherson, Albion (Iowa No. 103) and Richland (Iowa No. 
105), were added. The annual and average yields of three strains of 
the Kherson, four strains of the Sixty-Day, and four other varieties 
of oats grown at Moccasin during two or more years of the 10-year 
period from 1908 to 1917, inclusive, are shown in Table XXVI.

1 Crop destroyed by hail in 1912. 
2 Made second growth during rainy weather in August; not ripe whenfirst frost came. 
Reference to Table XXVI shows rather conclusively that the 
early varieties, Kherson and Sixty-Day, outyielded all other oats at 
Moccasin. The difference in yield in favor of these varieties over 
the midseason varieties is more than 10 bushels on the 9-year average. 
The Early Champion, an early white open-panicled variety, and the 
White Tartar, a late side oat, grown from 1908 to 1911, yielded 
much less each year than the Kherson and Sixty-Day. The two 
pure-line selections of Sixty-Day (C. I. Nos. 626 and 789) slightly 
exceeded the unselected Kherson and Sixty-Day in average yield. 
a Data compiled from U. S. Department of Agriculture Bulletin 398 (14), and from unpublished annual 
reports of Mr. N. C Donaldson, formerly scientific assistant in charge of cereal experiments at the Judith 
Basin substation, to the Office of Cereal Investigations.
