RATE-OF-SEEDING EXPERIMENTS. 
A rate-of-seeding experiment with Hansen proso was conducted 
on dry land in 1917. The experiment was 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, while 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.
