In 1913 the sowings were in tenth-acre plats on land that was 

 plowed in August, double disked twice, and harrowed before seed- 

 ing. The sowings were made on October 5, 1912. Little or no 

 winterkilling occurred. The seasonal rainfall was below normal 

 and the yields were relatively low. With the Turkey the highest yields 

 were obtained from the 5-peck and 6-peck rates, while with the 

 Ghirka Winter the 3-peck and 6-peck rates gave the highest yields. 



In 1914 the two varieties were again grown in tenth-acre plats on 

 fallow land. The seed was sown on September 10, 1913. There 

 was sufficient moisture present in the soil to start germination im- 

 mediatel}^ and a good fall growth resulted. The winter was cold 

 and open, and as a result all rate sowings were so badly winterkilled 

 that the plats were reseeded to spring crops. 



In 1915 the rate-of -seeding test included rates of 2 to 6 pecks 

 per acre. Sowings were rnade on September 9, 1914, in triplicate 

 thirtieth-acre plats on fallow land. The stands obtained were good 

 and an excellent fall growth resulted. All plats had a high winter 

 survival and the yields were high. The 3-peck and 6-peck rates 

 gave the highest yields with the Turkey wheat, while with the 

 Ghirka Winter there was a gradual decrease in yield as the rate of 

 seeding increased. 



The average yields for the three years, 1913 to 1915, inclusive, 

 are shown in Table VIIL With the Turkey, the highest average 

 yields were obtained from the 3-peck, 5-peck, and 6-peck rates of 

 seeding. The differences in yields from these rates were very small. 

 With the Ghirka Winter the highest average yield was obtained from 

 the 3-peck rate of seeding. Light seeding probably is to be preferred. 

 It is the practice on the farms to sow about 3 pecks per acre in this 

 section. 



DATE-OF-SEEDING EXPERIMENTS. 



Date-of -seeding experiments with the Turkey and Ghirka Winter 

 wheats have been conducted since 1913. The annual and average 

 yields obtained from the date-of -seeding tests are shown in Table IX. 



In 1913 the sowings were in tenth-acre plats on breaking. The 

 highest yields were from the earlier sowings. In 1914 the sowings 

 were in tenth-acre plats on fallow land. Better stands and better 

 faE. growth were obtained from the earlier sowings. Winterkilhng 

 was severe on all plats. The plats of both varieties sown Septem- 

 ber 1 survived the winter best and were harvested. The plats sown 

 on other dates were reseeded to spring crops. 



In 1915 the sowings were in triplicate thirtieth-acre plats on fal- 

 low land. Good stands and excellent fall growth were obtained from 

 the three earlier seedings. From the two later seedings fair stands
