Many varieties also were grown in nursery rows. Of these, an 
unnamed variety, designated as C. I. No. 357, outyielded all other 
varieties and strains during a period of several years. This variety 
was being increased for plat experiments in 1918, but was never 
grown in plats at Newell. 
RATE-OF-SEEDING EXPERIMENTS. 
A rate-of-seeding experiment with oats was conducted on dry land 
during six seasons. Good yields were obtained in all years except 
1910 and 1912. These rates of seeding varied by 2-peck intervals 
from 2 to 12 pecks per acre, but only four different rates were sown 
during all of the years. The varieties used in the experiment were 
Kherson, C. I. No. 459, in 1909 and 1910; Sixty-Day, C.I. No. 165, 
in 1912 and 1913 ; and Sixty-Day selection. No. 165-566, in 1915 and 
1916. As these varieties are of very similar character, the data are 
practically as uniform as if the same variety had been grown through- 
out the entire experiment. The yields are shown in Table XX. 
The highest average yields were obtained from sowing the oats at 
the rate of 6 pecks per acre, with a gradual decrease if sown at 
higher or lower rates of seeding. The results were so strikingly in 
favor of the 6-peck rate that the experiment was discontinued in 
1916.

Table XXI shows the average number of days from emergence 
to maturity, the height, weight per bushel, stand of plants per acre, 
and yields in pounds per acre of grain and straw of the oats in the 
rate-of-seeding experiments. The data are shown for only four 
rates of seeding, viz, 4, 6, 8, and 10 pecks per acre. The period of 
maturity and the height of the plants decrease with the increase in 
the rate of seeding. The weights per bushel are slightly higher 
from the heavier rates of seeding. The number of plants per acre 
is not quite proportional to the rate of seeding. This is due largely 
to the error in counting the plants in the thicker seedings where the
