Table XXXVI shows that the three varieties classed as midseason 
white have outyielded the Sixty-Day and the Kherson. The best 
midseason white oat, Swedish Select, has outyielded the Kherson by 
4.7 bushels. The Probsteier, a midseason yellow variety, also has 
outyielded both the Sixty-Day and the Kherson by about 2 bushels. 
Although these tests have not been of sufficient duration to be 
conclusive, the evidence indicates that in this section of the Great 
Plains the midseason white varieties generally will outyield the 
Kherson and Sixty-Day and therefore are to be recommended. 
Results in Colorado. 1 
Kherson and Sixty-Day oats have been included in the varietal 
experiments at the Akron (Colo.) Field Station since they were begun 
in 1908. The annual and average yields of these two varieties, three 
selections from them, and five other varieties of oats grown in one 
or more years in the 10-year period from 1908 to 1917, inclusive, are 
presented in Table XXXVII. 
The data shown in Table XXXVII indicate that there is little 
choice at Akron between the Kherson and Sixty-Day and the mid- 
season white varieties, Colorado No. 37 and Swedish Select. The 
Kherson has outyielded the Colorado No. 37 by a little more than 
2 bushels, but the Sixty-Day has fallen below both the Colorado 
No. 37 and the Swedish Select by about the same quantity. A 
comparison of the yields for the years 1912 to 1917 shows that Burt, 
an early red oat, has slightly outyielded the Kherson. In this period 
i The results obtained in 1915 and previous years were reported in U. S. Department of Agriculture 
Bulletin 402 (25). Later data are compiled from unpublished annual reports of Mr. George A. McMurdo, 
formerly scientific assistant in charge of cereal experiments at the Akron Field Station (1918) and Mr. 
F. A. Coffman, now scientific assistant in charge at Akron, to the Office of Cereal Investigations.
