CEREAL EXPERIMENTS AT THE AKRON FIELD STATION. 25 
VARIETAL EXPERIMENTS. 
Varietal experiments with oats have been conducted both in field 
plats and in the nursery. 
PLAT EXPERIMENTS, 
Fifteen varieties and several strains of spring oats have been 
grown in field plats. One of the strains shows some promise and 
is reported in this bulletin. Others have failed to produce yields 
superior to those of the parent varieties and have been discarded. 
No variety of the late groups has been grown continuously. Table 
XVII shows the annual and average yields of the 16 varieties and 
strains grown on the Akron Field Station in the 8-year period from 
1908 to 1915, inclusive. They have been divided into three groups, 
according to the time of maturity.

As shown in Table XVII, the Kherson (C. I. No. 459) has an average 
yield of 44.7 bushels per acre for the 8-year period. The variety 
ranking second is Colorado No. 37 (C. I. No. 619) in the midseason 
group. Its average yield is 43.9 bushels. When deduction is made 
for the favorable location of Colorado No. 37 in 1911, the average 
yield becomes the same as that of Swedish Select (C. I. No. 134), | 
41.9 bushels. The Sixty-Day variety (C. I. No. 165) has yielded 
less than the Kherson variety in all years except 1909. Its average 
yield of 39.3 bushels per acre is 5.4 bushels less than that of the 
Kherson. The selection of the Sixty-Day variety, listed as Sixty- 
Day 4P2, seems to be just about equal to the parent variety. A
