ecks to the acre. The eight-year average yields from seedings 
eavier than 2 pecks per acre were from 1.7 to 2.6 bushels more than 
those from seedings at 2 pecks or less per acre. The data may not 
be sufficient to permit drawing definite conclusions, but apparently a 
seeding rate in excess of 2 pecks per acre is more profitable than a seed- 
ing rate of 2 pecks or less. A seeding of 3 pecks per acre probably 
a provide the most favorable return at the least expenditure for 
seed,

1 Kharkof (C. I. No. 1583) was grown in 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, inclusive; and Kanred 
(C. I. No. 5146) in 1918. Where more than one variety was grown in any one year in rate-of-seeding experi- 
ments, the data for equal seeding rates of the varieties in that year have been averaged. As all rates were 
not grown in 1911 and 1912, the agronomic data for those years have not been included. 
An 11-year average yield, for the years 1911-1922 (excluding 1919), 
may be calculated, adding the average yields from both fallow and 
cornland given in Table 13 for the years 1920 to 1922. The only 
dates of seeding which produced satisfactory yields were those in 
early September and mid-September. If the results from these two 
dates are averaged and added to those in Table 11, the il-year 
average yields for the seedings at 2, 3, 4, and 5 pecks are 20.4, 22.1, 
22.0, and 22.6 bushels, respectively. These data still further empha- 
size the conclusions, given above, that a seeding of 3 pecks or more is 
warranted. | 
EXPERIMENTS TO DETERMINE THE BEST RATE AND DATE OF SEEDING 
In order to determine the best rate of seeding on each of several 
dates combined experiments comparing rates and dates of seeding 
with Kanred winter wheat were started in the fall of 1919. The 
seeding rates range by 1-peck intervals from 1 to 5 pecks, inclusive. 
The dates of seeding are August 16, September 1 and 16, and October 
1 and 16, or as near thereto as practicable. Duplicate fiftieth-acre 
plats are sown on fallow and on corn ground at each rate of seeding 
on each date. 
Table 13 presents the annual and average yields on fallow and 
cornland obtained in 1920, 1921, and 1922 from the different rates 
sown on the different dates. Table 14 shows the average date of 
heading and ripening, height of straw, bushel weight, and yields of 
grain and straw on fallow, together with the average bushel weight 
and yield of grain and straw on cornland. In general, the wheat on 
cornland headed and ripened a day or two later than that on fallow. 
The straw averaged from 3 to 5 inches shorter. No stem-rust in- 
fection occurred on the wheat grown from the first two seedings on
