The data presented in Table VIII indicate that the early yellow 
varieties, Kherson and Sixty-Day, yielded well at Madison during 
the three years from 1905 to 1907, inclusive. In this period the 
Sixty-Day outyielded the Wisconsin Wonder, one of the leading mid- 
season varieties, by about 17 bushels. This is much more than the 
normal difference between these varieties, however. The principal 
objection to the Sixty-Day and the Kherson oats at the Wisconsin 
station has been their rather weak straw and consequent liability to 
lodge. They are best adapted to the low and more fertile soils in 
the southern portion of the State, where they usually ripen in suffi- 
cient time to escape the most severe attacks of rust. 
No report on experiments with oats has been published by the 
Wisconsin station since 1908, but in a letter dated December 5, 1917, 
Mr. B. D. Leith, assistant professor of agronomy at the University of 
Wisconsin, writes: 
We consider the Kherson oats particularly valuable under certain conditions. As 
a rule, we do not get as much lodging and rust, quite largely due to its earlier maturity. 
If it does lodge it fills out better than the Swedish Select when it lodges. 
Under adverse conditions it has been the highest yielding oat in our test plats. In 
1915 it was harvested before our heavy storms lodged the other oats, and the yields ran 
above 100 bushels to the acre. In 1917 the yield was one of the best, largely due to 
the fact that it was not lodged so badly as the other oats, and there was less grain lost 
in harvesting. In very hot, dry years where oats are usually light the Kherson has 
been one of our best yielders. 
We have experimented with both Sixty-Day and Kherson oats. We pedigreed a 
strain from each and the pedigreed No. 7 selection from the Kherson strain proved a 
slightly heavier yielder and a little larger kernel than the pedigreed No. 6 from the 
Sixty-Day strain, so we disseminated the pedigreed No. 7 to the farmers and did not 
disseminate the pedigreed No. 6. 
Farmers in the sandy regions report that they are well pleased with the pedigreed 
No. 7 oats. It seems to be better suited to these regions than the midseason oats. 
I have in my hand a letter from a farmer on clay-loam soil who reports a yield of 80 
bushels per acre from the pedigreed No. 7 oats last season. He states that it lodged 
considerably and if he had been able to save all the crop he feels sure that he would 
have received 100 bushels per acre. The real objection to this oats is that it can not 
command as high a price on the market as other oats. This man states that he will be 
obliged to take 3 cents a bushel less than he would for white oats. 
Results in Illinois. 
The Sixty-Day oat has been included in the varietal experiments 
at the Illinois station at Urbana (7) since 1905. This variety was 
also grown at De Kalb, in northern Illinois, during the four years 
from 1911 to 1914, inclusive, and at Fairfield, in southern Illinois, for 
several years. The Richland (Iowa No. 105), a yellow selection from 
the Kherson, was added to the tests at Urbana and De Kalb in 1915. 
The following year the Albion (Iowa No. 103), a white selection from 
the Kherson, was also grown at these two points.
