(Colo.) substation in 1909 and was tested in the seasons of 1909, 1910, 
and 1911. In 1910 a variety known as the New Roosevelt was 
received from Mr. Erastus Madsen, Elsinore, Utah. This oat came 
from Wisconsin in 1908 and was grown one year under irrigation at 
Elsinore. It resembles the Swedish Select variety, though the 
berry is shorter and the glumes are whiter than those of the latter. 
The average yields per acre of the Black American, Giant Yellow, 
and Sixty-Day varieties from 1904 to 1906, inclusive, were 31.7, 24.7, 
and 22.6 bushels, respectively.t. The average acre yields of the same 
varieties for 1907 to 1909, inclusive, were 25.3, 19.5, and 20.9 bushels, 
-respectively.’ 
A summary of the yields obtained from spring oats since 1908 is 
presented in Table XII.

Table XII shows that the Black American, the Giant Yellow, and 
the Swedish Select varieties have yielded most satisfactorily since 
1908. The Sixty-Day variety has given the lowest average yield and 
the Kherson oat also yielded low. The New Roosevelt oat has the 
highest average yield for the last three years. The average yields per 
acre for the varieties grown from 1909 to 1912, inclusive, are Black 
American, 15.2 bushels; Giant Yellow, 14.2 bushels; Swedish Select, 
13.6 bushels; and Sixty-Day, 9 bushels. The average yield per acre 
for the Boswell Winter oat during the same period is 17.2 bushels, or 2 
bushels higher than the Black American, which is the highest yielding 
spring variety. The yields are all low, and considerable work remains 
to be done before the oat crop is made a profitable one on the dry
