varieties Buffum and Minturki have not competed successfully with 
the earlier maturing varieties of better milling quality. Alton (Ghirka 
Winter) has yielded little more than the poorest yielding awned 
varieties and has nothing to recommend it except that it is awnless. 
DATE-OF-SEEDING EXPERIMENTS 
Date-of-seeding experiments with hard red winter wheat varieties 
were conducted each year from 1911 to 1918. No winter wheat. 
plats were sown in the fall of 1918, and in the fall of 1919 the com- 
bined rate-and-date experiment was started. The date-of-seeding 
experiments did not follow a definite outline until the fall of 1919, 
and as a result it is difficult to summarize the data for presentation. 
Drought reduced the yields of 1911, 1913, 1917, and 1918, but fair 
yields were obtained in 1912, 1914, 1915, and 1916. 
Fic. 13.—An increase field of Kanred winter wheat grown on fallow at the Akron Field Station in 1919 
which yielded about 35 bushels to the acre 
The yields obtained in 1911 to 1918, inclusive, are shown in Table 
9, and Table 10 shows the average agronomic data during the 8-year 
period. The figures presented show that the earlier seedings have 
produced better yields than the later seedings in practically every 
season. The only exception to this rule was in 1911, when wheat sown 
during the period from November 5 to December 2 yielded better 
than wheat sown during October or the latter part of September.
