REHUI.TS AT DK 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.

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 UEBANA. 



The annual and average yields of four strains of early yellow and 

 six other varieties of oats grown at the Ilhnois 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 outyielded the Richland (Iowa No. 

 103), a yeUow 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.
