grown in 1917; consequently the average from 1918 to 1923 is included 
to allow comparisons of this variety with the others. Of the three 
best-known varieties grown commercially, Kharkof outyielded Turkey 
in every year except the last two and averaged 25.8 bushels for the 
7-year period, as compared with 24.1 bushels for Turkey. The lower 
yield of Kharkof in 1923 was due partly to washing caused by run-off 
from melting snow in the spring. Kharkof outyielded Kanred every 
year except 1921, when the yields of both varieties were the same. 
Crimean, which is a similar strain of Turkey, has yielded well but 
slightly less than Kharkof. 
SPRING WHEAT 
Of the spring-wheat varieties 20 have been grown at Sheridan. 
Some of the varieties originally grown were discontinued after 1920, 
and others were added in 1921. Consequently, average yields for 
three periods are shown in Table 12 for these varieties as follows: 
From 1917 to 1920, from 1917 to 1923, and from 1921 to 1923. From 
1917 to 1922, inclusive, the varietal experiments with spring grains 
were on cornland, and in 1923 they were on fallow.

In general, the differences in yield between varieties of spring 
wheat were small and not consistent from 5'ear to year. The highest 
yielding variety for the entire 7-year period was Power, a Fife wheat 
commonly grown a few years ago, which averaged 17.3 bushels. 
The yield of Marquis for the same period, however, was only 0.6 of 
a bushel less. The durum varieties outyielded Marquis but by a 
smaller margin than Power. Kota, under trial for three years, out- 
yielded Marquis on the average by 1.9 bushels per acre. At other
