RATE-OF-SEEDING EXPERIMENT. 



A rate-of-seediiig test with Kherson oats has been conducted at 

 the Cheyenne Experiment Farm dm-ing 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.

DATK-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 throe 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, b(!twe(ui April 1 5 and May 1
