EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 



55 



The data given in Table XLII show that the midseason white 

 varieties have outyielded the early yellow ones at Nephi in a series of 

 years. The table also shows that in the 8-year period from 1910 

 to 1917, inclusive, the Boswcll Winter oat has outyielded all others, 

 despite the fact that in 1913 this variety entirely winterkilled. 



In the two years (1916 and 1917) in which they have been tested, 

 Albion and Richland, the two selections from Kherson, have out- 

 yielded all others at Nephi and appear to be of considerable promise 

 for central Utah. 



Results in Idaho.i 



The Kherson and Sixty-Day varieties have been included in the 

 dry-land experiments at Aberdeen, Idaho, since 1911, when co- 

 operative cereal investigations were begun at that station. Only 

 two other varieties, Swedish Select and a white selection from an oat 

 known as "Rustless, " have been included. These latter were grown 

 only during the years 1915, 1916, and 1917. Table XLIII shows the 

 annual and average yields of these varieties at Aberdeen.

1 Average of two plats. 



The early yellow varieties, IDierson and Sixty-Day, have decidedly 

 outyielded the Swedish Select, a midseason white variety. The 

 superiority of the early varieties has been so marked in a practical 

 as weU as in an experimental way that it has not been thought worth 

 while to include varieties representing other types in the experi- 

 ments on dry land.
