EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
17 
RESULTS AT DE KALB. 
The annual and average yields of the Sixty-Day, of two selections 
from the Kherson variety (Iowa No. 103 and Iowa No. 105), and of 
four other varieties of oats grown at De Kalb by the Illinois Agricul- 
tural Experiment Station in one or more years in the 10-year period 
from 1907 to 1916, inclusive, are shown in Table IX.

grown by the Illinois Agricultural Experiment Station (at De Kalb) during one or more 
years in the 10-year period from 1907 to 1916, inclusive.

The data shown in Table IX indicate that for northern Illinois the 
best midseason white varieties will outyield the early sorts. How- 
ever, in 1915 and 1916 the Albion (Iowa No. 103), a white selection 
of the Kherson, has yielded nearly as well as the Silvermine and the 
Schoenen, the two leading midseason white varieties. This new oat 
appears to be of considerable promise for northern Illinois. 
RESULTS AT URBANA. 
The annuai and average yields of four strains of early yellow and 
six other varieties of oats grown at the Illinois Agricultural Experi- 
ment Station at Urbana in one or more years during the 12-year 
period from 1905 to 1916, inclusive, are presented in Table X. 
The data given in Table X show that in central Illinois the early 
varieties outyield all others and are therefore to be recommended. 
So far the original Sixty-Day has outyi elded the Richland (Iowa No. 
103), a yellow selection from Kherson. The Albion (Iowa No. 105), 
however, a white selection from the Kherson, materially outyielded 
both the Kherson and the Sixty-Day in 1916, the first year it was 
grown at Urbana. Both these pure lines of Kherson appear to be well 
worth growing in central Illinois.
