EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS.

they were begun in 1910. The annual and average yields of the 
Sixty-Day and four other varieties grown during four or more years 
of the 7-year period from 1910 to 191 6, inclusive, are shown in Table 
XLVTTT. Owing to the lack of land no varieties of oats were grown 
atChico in 1917.

1 Yields of oats not comparable in 1912; plats were badly infested with wild oats and other weeds. 
2 Average of four check plats. 
Reference to Table XL VIII shows that in the six years, 1910, 1911, 
and 1913 to 1916, inclusive, the Red Rustproof has outyielded the 
Sixty-Day by 2.9 bushels at Chico. In the 4-year period from 1913 
to 1916, inclusive, the difference is about the same in favor of the 
Red Rustproof. In this period the Danish Island also has slightly 
outyielded the Sixty-Day. These tests indicate that the Red Rust- 
proof is to be preferred to all others in the central valleys of California. 
This is in accordance with the experience of farmers, and as a conse- 
quence the Red Rustproof is the variety commonly grown in Cali- 
fornia, where it is known as California Red, or Common California. 
Conclusions. 
The average yield of the leading variety in each group at the 
stations included in the western basin and coast areas is shown 
graphically in figure 13. 
The results presented in Tables XLII to XL VIII, inclusive, show 
that the early yellow varieties, Kherson and Sixty-Day, are high 
yielders under dry-land conditions at all the stations west of the 
Rocky Mountains with the exception of Nephi, Utah. The climatic 
conditions at this station seem to favor the midseason varieties. 
In western Washington (Puyallup) the rainfall is too heavy for it 
to be classed as a dry-land section. At the other four stations 
usually one or more of the midseason white varieties have slightly 
outyielded the Kherson and Sixty-Day.
