EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
55 
The data given in Table XLII show that the midseason white 
varieties have outyielded the early yellow ones at Nephi in a series of 
years. The table also shows that in the 8-year period from 1910 
to 1917, inclusive, the Boswell Winter oat has outyielded all others, 
despite the fact that in 1913 this variety entirely winterkilled. 
In the two years (1916 and 1917) in which they have been tested, 
Albion and Kichland, the two selections from Kherson, have out- 
yielded all others at Nephi and appear to be of considerable promise 
for central Utah. 
Results in Idaho. 1 
The Kherson and Sixty-Day varieties have been included in the 
dry-land experiments at Aberdeen, Idaho, since 1911, when co- 
operative cereal investigations were begun at that station. Only 
two other varieties, Swedish Select and a white selection from an oat 
known as "Kustless, " have been included. These latter were grown 
only during the years 1915, 1916, and 1917. Table XLIII shows the 
annual and average yields of these varieties at Aberdeen.

The early yellow varieties, Kherson and Sixty-Day, have decidedly 
outyielded the Swedish Select, a midseason white variety. The 
superiority of the early varieties has been so marked in a practical 
as well as in an experimental way that it has not been thought worth 
while to include varieties representing other types in the experi- 
ments on dry land.
