30 BULLETIN 823, U. S. DEPARTMENT OF AGRICULTURE. 
At the agricultural experiment station at St. Paul, in eastern 
Minnesota, early varieties have yielded equally as well as the best 
midseason varieties. At the Crookston substation in northwestern 
Minnesota the midseason varieties have outyielded the early varie- 
ties, Kherson and Sixty-Day. White Kussian, a late side oat, pop- 
ular in this section, however, has not exceeded the early varieties in 
average yield at this station. Two years' results at the Grand 
Kapids substation in north-central Minnesota favor the early varie- 
ties, but additional data are necessary before more definite conclu- 
sions can be drawn. 
Early varieties of the Sixty-Day type have slightly exceeded the 
leading midseason varieties in average yield per acre at the agri- 
cultural experiment station at Fargo in the Red River valley in 
southeastern North Dakota. 
At the agricultural experiment station at Brookings, in eastern 
South Dakota, Sixty-Day oats have decidedly outyielded all others 
and are to be strongly recommended. 
At the agricultural experiment station at Ames, in central Iowa, 
early varieties of the Kherson or Sixty-Day type have yielded better 
than the best midseason varieties. During the past seven years 
Richland, a short-strawed yellow oat, selected from Kherson, has 
consistently outyielded all others. Albion (Iowa No. 103), a white 
selection from the Kherson, is very popular in the State. 
At the agricultural experiment stations at Lincoln, Nebr., and 
Manhattan, Kans., the early red varieties, Burt and Red Rustproof, 
have yielded considerably better than the Kherson and Sixty-Day. 
The early yellow varieties have outyielded the midseason varieties 
and are the next best to grow in eastern Nebraska and Kansas. 
RESULTS IN THE LOWER MISSISSIPPI VALLEY. 
The section here designated as the lower Mississippi Valley includes 
Kentucky, Tennessee, Mississippi, Louisiana, Arkansas, southern 
Missouri, southeastern Kansas, and the eastern or more humid por- 
tions of Oklahoma and Texas. 
The spring oat crop in this section of the Lmited States is not an 
important one, and consequently very little experimental work has 
been done with it. The State agricultural experiment stations of 
Tennessee, Arkansas, and Missouri have reported some varietal ex- 
periments with Kherson and Sixty-Day oats. In some cases, com- 
parisons have been made with fall-sown varieties. 
The Tennessee Agricultural Experiment Station at Knoxville grew 
the Kherson variety during the five years from 1908 to 1912, inclu- 
sive, in comparison with winter oats as well as with other spring 
varieties. During the four years, 1910 to 1913, inclusive, the Missouri 
Agricultural Experiment Station grew the Kherson and a number 
of other varieties near Carthage (Jasper County), in southwestern 
Missouri. _
