Fig. 15. — Diaj?ram showing the mean acre yields 
(in bushel.s) of lofrrcn as compared with those of 
lowar as a standard oat variety in 35 trials on 
Iowa farms in 1022 and 1023 
Reference to the data 
presenteci in Table 18 shows 
that of the 12 varieties 
grown continuously for the 
12 years from 1911 to 1919, 
inclusive, and in 1921, 1922, 
and 1923, Richland pro- 
duced the highest average 
yield, with the midseason 
black oat, Joanette, a close 
second. Albion was ex- 
ceeded in yield by seven 
varieties. Of the midsea- 
son varieties, Silvermine 
and Green Russian were 
superior, their average 
yield being practically the 
same as that of Kherson. 
During the seven years 
from 1916 to 1919, inclu- 
sive, and in 1921, 1922, and
