CEREAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 29 
RATE-OF-SEEDING EXPERIMENT. 
A rate-of-seeding test with Kherson oats has been conducted at 
the Cheyenne Experiment Farm during the 3-year period, 1913 to 
1915, inclusive. Plats have been sown each year at the rate of 3, 
4, 5, 6, and 7 pecks per acre. The annual and average yields ob- 
tained in this test are shown in Table XVIII. Poor yields were 
obtained in 1913. The highest yield (16.6 bushels) was obtained 
from the plat sown at the rate of 3 pecks. In 1914 fair yields were 
obtained, the highest (28.7 bushels) being from the 6-peck rate. In 
1915 good yields were obtained, the highest (50.2 bushels) being 
produced from the 6-peck rate. The average yield from this test 
shows an increase in yield as the rate of seeding increased. Indi- 
cations are that 5 or 6 pecks per acre is about the right quantity 
to sow in southeastern Wyoming.

DATE-OF-SEEDING EXPERIMENT. 
A date-of-seeding test with Kherson oats has been conducted on 
the Cheyenne Experiment Farm during the three years, 1913 to 
1915, inclusive, Sowings have been made each year on April 15, 
May 1, and May 15. The annual and average yields obtained from 
this test are shown in Table XIX. In 1913 the May 1 sowing, in 
1914 the April 15 sowing, and in 1915 the May 15 sowing gave the 
highest yields. Thus in the three years each date of seeding has 
given the highest yield once. The highest average yield, as shown 
in Table XIX, has resulted from the early seeding. Oats should 
be sown early, between April 15 and May 1.
