EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
23 
The data contained in Table XIII show that on the average the 
midseason white varieties have slightly outyielded the Sixty-Day in 
northwestern Minnesota, the better varieties averaging about 4 
bushels more in the 5-year period from 1912 to 1916. In occasional 
unfavorable years, as in 1916, the early oats considerably outyielded 
the midseason varieties. The 5-year average yields of the Sixty-Day 
and the White Russian, a late side oat popular in this section, were 
practically the same. The Sixty-Day averaged about 8 bushels 
more than the Kherson for the 5-year period, but the difference is 
due entirely to wide variations in the yields in 1912 and 1913. 
RESULTS AT GRAND RAPIDS. 
The University of Minnesota Department of Agriculture has in- 
cluded the Kherson and Sixty-Day oats in the varietal experiments 
conducted at the North-Central Experiment. Station at Grand Rapids 
(26, p. 16). The results of these experiments are reported for the 
years 1915 and 1916. The annual and average yields of the Sixty- 
Day and Kherson and a number of other varieties are shown in 
Table XIV.

The data presented in Table XIV show that in 1915 the Kherson 
and Sixty-Day decidedly outyielded all other varieties at Grand 
Rapids. In 1916 occurred an unexplained wide difference in yield 
between them, the Kherson being the highest yielding and the Sixty- 
Day the lowest of the 12 varieties included in the tests. Evidently 
the Sixty-Day was grown under very unfavorable conditions or 
some discrepancy occurred in the experiments which resulted in 
the abnormally low yield. The average yield of the Kherson for the 
two years is 4.5 bushels higher than that of any other variety.
