CEREAL EXPERIMENTS AT THE AKRON FIELD STATION. 

 VARIETAL EXPERIMENTS. 



25 



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 

 X"\T!I shows the annual and average yields of the 16 varieties and 

 strairis 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 varietj'' 

 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 bu.shels 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
