EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
63 
Results under Irrigation in Idaho. 
RESULTS AT ABERDEEN.l 
The Kherson and Sixty-Day oats have been included in the cooper- 
ative varietal experiments conducted under irrigation at Aberdeen, 
Idaho, since 1913, when experimental work was begun at that sta- 
tion. Albion and Richland, two selections of Kherson from the Iowa 
station, were added to the tests in 1916. In Table LII the annual 
and average yields of these and seven other varieties grown at 
Aberdeen during two or more years in the 5-year period from 1913 
to 1917, inclusive, are presented.

Reference to Table LII shows that of the eight varieties which 
have been grown for five years the Early Mountain and Golden Rain 
only slightly outyielded the Kherson, with the Silvermine equaling 
the Kherson in yield. All of the midseason varieties except Lincoln, 
however, have outyielded the Sixty-Day in that period. In the 
2-year period, 1916 and 1917, the Kherson has outyielded all others. 
The Albion (Iowa No. 103), a white selection from Kherson, has aver- 
aged only 3 bushels less. Indications are that this new oat is of con- 
siderable promise for irrigated conditions in southern Idaho.
