20 BULLETIN 823, U. S. DEPARTMENT OE AGRICULTURE. 
Conditions in northern Illinois (De Kalb) are quite similar to those 
at Madison, Wis., but the data include those for several years favor- 
able to midseason varieties, so that on the average these have out- 
yielded the Sixty-Day. The yields of the Sixty-Day in the less 
favorable years with correspondingly higher prices, and particularly 
the high yields of the two Kherson selections from Iowa, indicate 
that early oats are desirable in this section. 
In central Illinois the Sixty-Day has considerably outyielded the 
midseason and late varieties in an 11-year test and can be strongly 
recommended. In southern Illinois, as indicated by the test at 
Fairfield, the Red Rustproof is to be preferred. 
RESULTS IN THE WEST NORTH-CENTRAL SECTION. 
The west north-central section includes the States of Minnesota, 
Iowa, and Missouri, and the eastern and more humid portions of the 
Dakotas, Nebraska, and Kansas. Varietal experiments including 
Kherson and Sixty-Day oats have been conducted in all these States 
either independently by the State agricultural experiment stations or 
in cooperation with the United States Department of Agriculture. 
The Minnesota station has grown the Kherson and Sixty-Day oats 
since 1906, but has not published the results of its experiments 
since 1908. The Northwest Experiment Station at Crooks ton, how- 
ever, has recently reported the results of varietal trials, including 
these varieties, during the five years from 1912 to 1916. The North- 
Central Experiment Station at Grand Rapids also has reported the 
results of varietal experiments with Kherson and Sixty-Day oats for 
1915 and 1916. The data available from eastern North Dakota are 
for the years from 1901 to 1908, and from South Dakota for the years 
from 1904 to 1917. Results are available from the Iowa station for 
the 11 years from 1907 to 1917, inclusive. Nebraska has recently 
published data on varietal experiments with oats, so that figures are 
available for the 14 years from 1903 to 1916. The Kansas station 
has published results obtained during the 7-year period from 1903 
to 1909. The data since 1910 have been obtained in cooperation 
with the United States Department of Agriculture. No reports of 
varietal trials of oats at the Missouri station have been published for 
many years. 
Results in Minnesota. 
RESULTS AT UNIVERSITY FARM. 
The annual and average yields of the Kherson, Sixty-Day, and six 
other commercial varieties of oats grown at the Minnesota Agricul- 
tural Experiment Station, University Farm, St. Paul (5), during the 
3-year period 1906 to 1908, inclusive, are presented in Table XII.
