EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 

 Results under Irrigation in Nevada. 



65 



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
