but it is generally able to recover in a large measure and to produce 
a fair yield of forage when other crops succumb. An early variety 
of corn is recommended on account of the short season. North- 
western Dent is the variety mainly grown at the experiment station. 
Notwithstanding the fact that oats are subject to injury from 
drought and hail, they are very extensively grown. In the varietal 
experiment the highest 9-year average yield of grain, 31.1 bushels 
per acre, was produced by Kherson. The average yield of straw of 
this variety was 1,845 pounds per acre. The largest average total 
yield was produced by Ligowa. The acre yield of this variety was 
30.8 bushels of grain and 2,217 pounds of straw. 
Barley has not been injured by hail and drought so severely as 
oats. The straw of the early varieties is short, the same as with 
oats. White Smyrna is recommended for an early variety and Horn 
for a late variety. The average acre yields for the 4-year period 
from 1918 to 1921, inclusive, were 28.3 bushels from White Smyrna 
and 30.1 bushels from Horn. Both are two-rowed bearded varieties, 
but the beards are not so heavy or persistent as they are on Coast, 
a commonly grown variety. 
DATES AND RATES OF SEEDING 
During the seven years from 1913 to 1919, inclusive, experiments 
were conducted in cooperation with the Office of Cereal Investiga- 
tions of the Bureau of Plant Industry to determine the best dates 
and rates of seeding the several spring-sown small grains. Similar 
experiments were conducted with winter wheat for the four years 
from 1918 to 1921, inclusive. A common wheat, Ladoga, sometimes 
known as Spring Turkey, was used in the date-of-seeding experi- 
ments with spring wheat. The highest average yield for the seven 
years from 1913 to 1919, inclusive, was 12.9 bushels per acre from 
seeding on May 1. The April 15 seeding averaged 10.9 bushels and 
the May 15 seeding 10.7 bushels. Seeding as late as June 1 and 
June 15 resulted in a marked falling off in yields. The growing and 
fruiting periods of such late seedings are extended into the drier part 
of the season and maturity is hastened by drought. 
A durum wheat, Arnautka (C. I. No. 1493), was used in the rate- 
of-seeding experiment with spring wheat. The yield of wheat is not 
influenced so much by the rate of seeding, within a considerable 
range, as it is by the date of seeding. The average acre yields for 
the seven years from 1913 to 1919, inclusive, from seeding at the 
rates of 2, 3, 4, 5, and 6 pecks per acre were 15.1, 15.7, 16.2, 15.9, 
and 15.7 bushels, respectively. Stands were rather thin and weedy 
from the sowings made at the rate of 2 pecks, and the yields were 
slightly decreased from rates of seeding heavier than 4 pecks. The 
results show the best rates of seeding to be from 3 to 4 pecks per acre. 
Experiments on the date of seeding oats were conducted with 
Swedish Select, a midseason variety, and Kherson, an early variety. 
The experiments with Swedish Select covered only the three years 
from 1917 to 1919, inclusive. During these three years the average 
acre yields from the different dates of seeding were May 1, 29.2 
bushels; May 15, 33.5 bushels; and June 1, 23.2 bushels. The ex- 
periments with Kherson covered the seven years from 1913 to 1919, 
inclusive. The average acre yields from the different dates of seeding
