OAT VARIETIES FOR THE CORX BELT

results are presented in Table 4. The home-grov,ai varieties and the 
number of trials in which each was compared with the Albion 
were as follows : Swedish Select 37, Silvermine 20, Early Champion 
26, Kherson 66, Green Russian 34, miscellaneous 27, and unknown 
varieties 57.

The data of Table 4 show an average annual gain of 4.34 bushels 
per acre for Albion over these home-grown varieties. Some of the 
difference probably was due to the better quality of the Albion seed, 
as this seed was ahYa3^s cleaned and prepared by the Iowa station. 
Allowing a reasonable reduction for this factor, it is safe to estimate 
that the variety has raised the average yields on the fields where it 
has been grown in Iowa by at least 3 bushels per acre. 
RATIO OF GRAIN TO STRAW 
Albion is an early variety and, as would be expected, has a com- 
paratively high yield of grain in proportion to straw. For three 
years the soils section of the Iowa Agricultural Experiment Station 
used this variety on the fertility plats at the station farm. The 
average acre yield of grain on 59 plats in 1915, 1916, and 1917 was 
60.9 bushels (1,948.8 pounds). The average yield of grain from 1 
ton of bundles was 1,124 pounds, or 56 per cent grain and 44 per 
cent straw by weight.

RATE-OF-SEEDING EXPERIMENTS 
The Albion oat was grown in a rate-of -seeding experiment in 1912 
only. The data obtained in this experiment are shown in Table 5.
