EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS.

Results in Michigan. 
No results of varietal tests of oats at the Michigan station have 
been published for many years. Such information as is available, 
however, indicates that midseason and late oats are to be preferred to 
the Sixty-Day and Kherson for growing in that State. The Worthy 
and the Success, midseason white varieties developed by the agri- 
cultural experiment station at East Lansing, are particularly recom- 
mended. In a recent letter, Prof. Frank A. Spragg, plant breeder 
of the Michigan station, says: 
We have had a number of strains of Sixty-Day and Kherson at various times in our 
varietal tests, but have never gotten as good yields as from the midseason and late 
varieties. Conditions in Michigan are quite different from those in the corn belt, 
where earliness in oats is desirable in order to enable them to ripen before hot summer 
weather. Our spring is often late, but when it opens everything comes with a rush, 
the hot spell usually striking us about July 1 and lasting two or three weeks. This 
hot weather injures the early oats. The oat that yields best with us is one that is 
not far enough advanced at this time to be hurt by hot weather and which heads out 
and ripens early in August immediately after the hot spell. 
Early oats should be of advantage in the Upper Peninsula of Michigan, because the 
season there starts late and rains in August are frequent, interfering with the harvest- 
ing of the later varieties. The Sixty-Day and Kherson are very unpopular, however, 
because farmers do not like the small, slender kernels. 
Results in Wisconsin. 
The results of varietal tests, including the Kherson and Sixty-Day 
oats, are reported for the years 1905 to 1907, inclusive, by the Wis- 
consin Agricultural Experiment Station (29). Since 1907 no tabu- 
lated results on varietal tests with oats have been reported. The 
annual and average yields of the Kherson and Sixty-Day and of three 
other varieties of oats grown at the Wisconsin Agricultural Experi- 
ment Station during the three years from 1905 to 1907, inclusive, are 
shown in Table VIII.
