tained from the 2-peck rate. For the three years, the 2-peck rate of 
seeding gave the highest average yield. However, there is little 
difference in the average yields at the 2-peck, 3-peck, and 4-peck 
rates.

DATE-OF-SEEDING EXPERIMENT. 
A date-of-seeding experiment with Spring Turkey common wheat 
has been conducted at the Cheyenne Experiment Farm during the 
three years, 1913, 1914, and 1915. The annual and average yields 
obtained in this test are shown in Table XIV.

a Computed yield. 
In 1913 the date-of-seeding test was sown in tenth-acre plats on 
fall-plowed breaking. The stands obtained were good. The earlier 
date of seeding gave the highest yield. The drill failed to sow a por- 
tion of the plat sown on April 15. The portion actually seeded, 
one-fifteenth of an acre, was harvested, and the yield computed on a 
tenth-acre basis. ( 
In 1914 the date-of-seeding test was sown in tenth-acre plats on 
spring-plowed fallow land. Stands were good. The highest yield 
was obtained from the May 1 seeding. 
In 1915 the test was sown in duplicate twentieth-acre plats on 
double-disked corn ground. The highest yield was obtained again
