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 Russian, 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 

 Rapids 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 hi 

 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 Klierson 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 VaUey 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 United 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.
