Results in Montana.^ 



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. 



Table XXVI. — Annual and average yields of seven strains of Kherson and Sixty-Day 

 and of four other varieties of oats grown at the Judith Basin substation, Moccasin,

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.

 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.
