1 Bushel weights not recorded for all dates in all years. 
2 Average for seven years, no plats sown early in fall of 1912. 
3 Average for seven years, 1917 omitted. 
4 Average for six years, 1912 and 1916 omitted. i 
5 Wheat sown after November 5 emerged unevenly during the winter and early spring. 
6 Large straw yield due to abundance of weeds. 
RATE-OF-SEEDING EXPERIMENTS 
Experiments to determine the best rate to sow hard red winter 
wheat have been made since 1911, but as no winter-wheat plats were 
sown in the fall of 1918 and the combined experiments comparing 
rates and dates of seeding were started in the fall of 1919, the results 
from the rate-of-seeding experiment are presented for only the 8-year 
period from 1911 to 1918, inclusive. Good crops were obtained in- 
1912, 1914, 1915, and 1916. In 1911, 1913, 1917, and 1918 the yields 
were low, owing to dry weather during the critical stages of growth. 
The rates of seeding ranged from 1 to 6 pecks per acre at 1-peck 
intervals in all years except 1911 and 1912, when they ranged from 
2 to 5 pecks per acre. The yields are shown in Table 11, and in 
Table 12 the average agronomic data for the different rates for the 
period from 1913 to 1918, inclusive, are presented.

1 The following varieties and strains have been used in this experiment: Kharkof (C. I. No. 1583) fro m 
1911 to 1913 and from 1916 to 1918, inclusive; Kharkof (C. I. No. 1442) in 1914; Kharkof (C. I. No. 4207) in 
1915; Crimean (C. I. No. 1559) from 1915 to 1918; and Kanred (C. I. No. 5146) in 1918. Where more than 
one variety was grown in rate-of-seeding experiments in any one year, the yields from equal rates of different 
varieties have been averaged. 
The yields obtained from plats sown at different rates from 2 to 6 
ecks aS acre showed little variation in many seasons. The yields 
rom the lighter seedings, however, have been the lowest most often. 
In all years the better yields were from the seedings heavier than 2
