tained from the 2-peck rate. For the three years, the 2-peck rate of 

 seedmg gave the highest average yield. However, there is httle 

 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 THirkey common wheat 

 has been conducted at the Cheyenne Experiment Farm diu-ing the 

 three years, 1913, 1914, and 1915. The annual and average yields 

 obtained in this test are shown in Table XIV.

ed yield. 











In 1913 the date-of-seeding test was sown in tenth-acre plats on 

 faU-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 aero, was harvested, and the yield computed on a 

 tenth-acre basis. 



In 1914 the date-of-secding 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 1015 tli(! test was sown in duplicate twentieth-acre plats on 

 doiihlc-diskcd co/ti ^^roiind. Tlic highest yield was ()])t)iined again
