atively true. Albion (lowa No. 103), a white selection from Kher- 
son, has yielded fairly well during the period it has been included. 
The earlier varieties have been able to outyield the later varieties 
because of their ability to escape drought. The extreme earliness 
of certain selections from Burt and some of the most recent introduc- 
tions, such as Ful- 
25.30 35 ghum and Kanota,

Fic. 19.—Average acre yields of three varieties of oats grown at the 9 
Akron Field Station during the 15-year period, 1908-1922, inclusive 1922 on fallow and 
on cornland. These 
data show that Albion has outyielded all other varieties during this 
period. Table 23 shows the average data recorded on dates of head- 
ing and maturity, height, bushel weight, and yields of grain and 
straw for the seven varieties of oats which were grown during the 
6-year period.

Colburt, the Burt selection made at the Akron Field Station, 
headed only about two days earlier than Kherson and the white 
selection from Kherson known as Albion, but matured nearly a week 
earlier. The midseason and late varieties headed a week to 10 days 
later than Kherson and matured 10 days to 2 weeks later. The 
maturity of the later varieties was hastened in some years by dry 
weather. The previous treatment of the land made no appreciable 
difference in the dates of heading and ripening, but all varieties 
grew taller on fallow than on cornland. The difference in height 
was more marked in the midseason and late than in the early varie- 
ties. Yields of both grain and straw were heavier on fallow than on 
cornland. In this six-year period Albion produced practically as 
much straw as any of the later varieties, materially exceeding Kherson 
in this respect.
