EXPEKIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
65 
Results under Irrigation in Nevada. 
The annual and average yields of the Kherson, the Sixty-Day, and 
several other varieties of oats grown under irrigation at the Nevada 
Agricultural Experiment Station at Reno (22, p. 31-34) during two 
or more years in the 3-year period from 1914 to 1916, inclusive, are 
shown in Table LIV.

The data shown in Table LIV are the yields from very small 
plats, not replicated sufficiently to eliminate a high percentage of 
experimental error. The midseason varieties outyielded the Kherson 
and the Sixty-Day by a sufficiently wide margin, however, to indicate 
that they are to be preferred for growing under irrigation in western 
Nevada, although climatic conditions appear to favor early oats. 
In reporting his results, Professor Knight states : 
The lack of humidity together with the intense heat of the sun during the ripening 
period often causes the panicles to blast and turn white before the grain is fully devel- 
oped and while the culms and leaves are still green. When affected this way, a large 
portion of the oats shatters to the ground before and during harvest. 
Conclusions. » 
The average yield of the leading variety in each group at the 
stations where experiments have been made under irrigation in the 
northern Great Plains and western basin areas is shown graphically 
in figure 15. 
From the data presented in the preceding pages it appears that 
in irrigated districts where early frosts may be expected the early
