EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



13 



Day and Kherson wore grown from 1905 to 1908. Reports of varietal 

 experiments at this station since 1908 have not included these varie- 

 ties. At the Illinois station at Urbana the Sixty-Day has been 

 grown since 1905, and it has also been included in varietal trials at 

 Do Kalb and Fairfield for several years. Yields of oat varieties at 

 the Wisconsin station have not been published since 1907; both the 

 Sixty-Day and the Kherson were grown that year and in the two 

 years previous. 



Results in Ohio. 



The annual and average yields of three strains of the Sixty-Day 

 and of thirteen other high-yielding varieties and selections grown 

 at the Ohio Agricultural Experiment Station at Wooster (49 and 51) 

 for five or more years of the 9-year period from 1904 to 1912, in- 

 clusive, are presented in Table VI.

Reference to Table VI shows that the Sixty-Day ranks fifth among 

 the commercial varieties which have been tested at Wooster durins: 

 the 9-year period from 1904 to 1912, inclusive, with an average yield 

 of 68.2 bushels. The highest yielding variety in this period was 

 the Siberian, with an average yield of 71.3 bushels. The Siberian is 

 a midseason white oat, as are also the other three varieties which out- 

 yielded the Sixty-Day, viz, Big Four, Siberian, and Improved Amer-
