KATE-OF-SEEDING EXPERIMENTS. 



A rate-of-seeding experiment with Hansen proso was conducted 

 on dry land in 19 IT. The experiment w^as sown at three different 

 rates, in triplicate, on June 19. The plats sown at 15 pounds per 

 acre yielded an average of 20.3 bushels, those sown at 22.5 pounds 

 yielded 22.3 bushels, wliile those sown at 30 pounds yielded 23.0 

 bushels per acre. It is thus seen that the 30-pound rate gave a 

 slightly higher net yield than the 22.5-pound rate. Under con- 

 ditions of earlier seeding or late drought a thinner seeding might 

 have given the highest yield. Conclusions can not be drawn from 

 a 1-year experiment, but apparently not less than 25 to 30 pounds 

 of proso should be sown per acre for best results under the conditions 

 at Newell. 



SPACING EXPERIMENTS. 



Black Voronezh proso was grown in an experiment in 1916 and 

 1917 to determine the distance between drill rows which would pro- 

 duce maximum yields. The seed was sown with the grain drill in 

 rows 7, 14, and 21 inches apart in triplicated plats. The drill was 

 set in the same notch for all spacings, so that the plats having rows 

 7 inches apart were sown at the rate of about 28 pounds per acre, 

 those with rows 14 inches apart at the rate of 14 pounds per acre, 

 and those in rows 21 inches apart at about 8.5 pounds per acre. The 

 yields from the experiment are shown in Table XXVII.
