Table 25 shows the average dates of heading and ripening, the 
height, bushel weight, and acre yields in pounds of straw and bushels 
of grain in the rate-of-seeding experiment. Increase in the seeding 
rate resulted in earlier heading and maturity. The height of plant 
and the bushel weight did not vary appreciably with the seeding rate. 
The acre yield of straw varied inversely with the rate of seeding. 
This may be partly accounted for by the presence of numerous weeds 
in the plats sown at the lower rates. The yields of grain increased’ 
with the increased rates of seeding and indicate clearly that the 
heavier seeding rates of 4 to 6 pecks per acre are better than seeding 
rates of 2 and 3 pecks per acre.

NURSERY EXPERIMENTS 
The growing of head selections of oats was begun in 1908 and has 
been continued almost every year since. The most promising 
selection so far made at Akron, which is grown to any extent, is one 
from Burt (C. I. No. 293). This selection, No. 293-6—-09, made by 
Wilson G. Shelley, has now been named “ Colburt” (C. I. No. 2019). 
It has brown to black Kernels, is of the satwva type, breeds compara- 
tively true, and has yielded: next to Kherson over the 11-year 
period from 1912 to 1922, inclusive. Several hundred selections of 
Burt and Kherson oats are now being grown in nursery rows and 
selection plats. Some of these selections appear to be especially 
promising. 
EXPERIMENTS WITH BARLEY 
The acre yields of the best varieties of barley have been greater 
than those of any of the other cereals grown for long periods. Most 
of the barley varieties mature slightly earlier than oats or wheat, 
which permits sowing the crop at a later date. Barley grown in 
this district is used exclusively as a feed crop and is mostly fed on 
the farms where grown. Its market value is therefore of minor 
importance. 
Winter barley has been sown several years, but has never survived 
the winter sufficiently well to justify growing it. 
VARIETAL EXPERIMENTS 
Since 1908, 30 varieties and strains of spring barley have been 
grown in the varietal experiments. Only three varieties were grown 
during the entire period; eight varieties were grown continuously
