BULLETIN" 823, U. S. DEPARTMENT OF AGRICULTURE. 
The altitude of Nephi, Utah (6,000 feet), is the highest of the 
stations here discussed, and that of Chico, Calif. (189 feet), is the 
lowest. Aberdeen and Burns each have an altitude of more than 
4,000 feet. At the Burns station in the Harney Valley frost fre- 
quently occurs during the summer months. The advantage of early 
varieties of oats over midseason or late varieties is apparent under 
such conditions. The summers are very warm and evaporation is 
fairly high, but wind velocities are low in most of these sections. The 
soils for the most part vary from sandy clay to silt loams. 
Results in Utah. 1 
The Sixty-Day oat has been included in the cooperative varietal 
experiments at Nephi since the work was started at that station in 
1908. The Kherson variety was grown only during the years 1909 to 
1911, inclusive. Two selections of Kherson from the Iowa station 
were added to the experiments in 1916. In addition to these, only a 
few other varieties have been included in the tests at Nephi. The 
annual and average yields of those varieties which have been grown 
during three or more years in the 10-year period from 1908 to 1917, 
inclusive, are presented in Table XLII. 
Table XLII. — Annual and average yields of the Sixty-Day, the Kherson, the Richland, 
the Albion, and four other varieties of oats grown at the Nephi ( Utah) substation during 
tvoo or more years in the 10-year period from 1908 to 1917, inclusive.
