Conditions in northern Illinois (Do 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 Miniiesota, 

 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 pubHshed the results of its experiments 

 since 1908. The Northwest Experiment Station at Crookston, 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 

 pubUshed 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.
