averaged 1.3 bushels per acre more than Kharkof, C. I. Xo. 1583, 
and also considerably outyielded the parent variety. Turkey, C. I. 
Xo. 3055, during the three years the latter was grown. The Be- 
loglina yielded nearly as much as the other Crimean strains except 
in 1915, when only a single plat of that variety was grown, this being 
in an unfavorable location. 
The awnless strains of the Alton (Ghirka Winter) group yielded 
less than the awned varieties of the Crimean group. The Alton 
variety was grown only in 1916 and 1917 and did not appear prom- 
ising. Three other strains or selections of a type similar to Alton 
have been grown. Only one, C. I. Xo. 5297, an awnless selection or 
separation from Kharkof, was grown during each of the four years. 
Although this variety yielded somewhat less than Kharkof, it has 
the advantage of being awnless and is probably nearly equal to 
Kharkof in quality. 
RATE-OF-SEEDING EXPERIMENTS. 
Kate-of-seeding experiments with Kharkof wheat, C. I. Xo. 1442, 
were begun in the fall of 1915. The wheat was sown in triplicated 
fiftieth-acre plats at the rates of 3, 4, 5, and 6 pecks per acre. Re- 
sults were obtained during three seasons. 
The wheat was badly rusted in 1916, under which conditions the 
highest yields were obtained from the thickly sown plats. In 1917 
and 1918 emergence was late and the stands of wheat were thin in 
the spring. The wheat was sown rather late during each of the 
three seasons, because of having to wait for the removal of the corn 
or root crop before preparing the land for wheat. 
The yields are shown in Table XXXVI.

The highest average yield was obtained from the plats sown at 
the rate of 5 pecks per acre. The 6-peck rate gave the highest 
yield in 1916, the 4-peck rate in 1917, and the 5-peck rate in 1918. 
When the wheat is sown late the rate of seeding should be 5 pecks 
per acre. A seeding of less than 4 pecks per acre may be expected 
to cause reduced yields.
