selections from the Sixty-Day have sHghtly exceeded the parent 

 variety in average yield in the years they have been grown. 



There is some objection to these oats by farmers because of the 

 yellow color and small size of the kernel. As oats are commonly 

 grown in Montana for feed rather than to sell, the yellow color is 

 not objectionable. Because of the thin hulls, these varieties have a 

 larger proportion of kernel to hull than the larger types of oats. 



The Sixty-Day is being increased at the Judith Basin substation. 

 About 2,000 bushels have already been distributed throughout the 

 dry-land areas of the State, and the results obtained seem to indicate 

 that for these lands the Sixty-Day variety is the best.

MIDSEASON VARIETIES. 



Of the varieties of oats that have been tested at Moccasin, 13 can 

 be classed as midseason in maturity. The Swedish Select is the only 

 one ill tliis group that has been grown in the entire seven years. This 

 variety has a 7-year average yield of 46.5 bushels, which is 15.9 

 bushels lower than the 7-year average yield of the Sixty-Day. Other 

 typical varieties of this group are the Danish, Lincoln, and Silver- 

 mine. All these are more suitable for growing under irrigation than 

 on the dry farms m Montana. • 



The varieties of the midseason group have tall, coarse straw and 

 large, rather broad gram. They are from a week to 10 days later 

 in maturing than varieties of the early group. 



LATE VARIETIES. 



All the late varieties which have been gi'own are side oats. The, 

 White Russian, Wliite Tartarian, and other late varieties have not 

 produced good yields at Moccasm except m 1909. In that year they
