CEREAL EXPERIMENTS AT THE AKRON FIELD STATION. Pail 
The data in Table XVIII show that the difference in date of 
maturity between the early and midseason and between the mid- 
season and late groups is about 10 days. The varieties in the early 
group mature about July 20, those of the midseason group about 
July 31, and those of the late group about August 9. There is an in- 
crease of about 500 pounds per acre in the straw yield of each suc- 
cessively later group. As oat straw has considerable feeding value 
this should be taken into account. Considering yields of both grain 
and straw, the midseason variety, Colorado No. 37 (C. I. No. 619), 
has given the best returns during the period. 
NURSERY EXPERIMENTS, 
A total of 61 varieties and several hundred strains have been 
tested in nursery rows. The varieties that have shown promise have 
been advanced to the field tests. With the exception of Sixty-Day 
4P2, they have not proved worthy of continued trial and have

quantity of material not adapted to the conditions at Akron. ‘The 
results are of a negative rather than a positive nature. 
RATE-OF-SEEDING EXPERIMENTS. 
An experiment was begun in 1911 to investigate the effect of rate 
of seeding on the yield per acre of oats. The Kherson variety (C. I, 
No. 459) has been used. Table XIX shows the annual and average 
yields obtained during the five years.
