ye BULLETIN 1287, U. S. DEPARTMENT OF AGRICULTURE 
The experiments reported in this bulletin have been conducted 
wholly on dry land. The results obtained from the experiments to 
and including 1915 have been published,? as have certain results 
obtained since that time. This bulletin was prepared in order to 
make available the unpublished results from the experiments con- 
ducted since 1915. 
In many cases the data obtained since 1915 show considerable 
variance from those obtained before that year. Seasonal conditions 
have varied widely, with resulting great fluctuations in the yields: 
of the different cereals. As this bulletin contains the results obtained 
over a period of 15 years, the data herein presented should indicate 
the relative values of the different cereals and should show definitely 
which are the best varieties and the best cropping systems for this 
region. The results obtained at the Akron Field Station are applica- 
ble to a large part of eastern Colorado and adjacent portions of north- 
western Kansas, western Nebraska, and southeastern Wyoming, 
especially on what are locally termed “hard lands.’’ The irrigated 
river valleys and the sand-hill sections present somewhat different 
conditions. 
The yields of the cereals compare very favorably with those 
obtained under dry-land conditions in other parts of the United 
States. Winter wheat, corn, barley, spring wheat, and oats are the 
most important cereals in this section. Wheat and corn are each of 
ereater economic importance than all other cereals combined. 
DESCRIPTION OF THE FIELD STATION 
LOCATION 
The Akron Field Station is located in northeastern Colorado, 
about 60 miles from the Nebraska line on the east as well as on the 
north, where Nebraska extends west beyond the northeast corner of 
Colorado to Wyoming. The station is 4 miles east of Akron, the 
county seat of Washington County. The town of Akron is located 
about 112 miles east of Denver, Colo., on the main line of the Chicago, 
Burlington & Quincy Railroad, running from Chicago and St. Louis 
to Denver. The railroad bounds the field station on the south. 
The station is shghtly west and north of 40° N. latitude and 103° W. 
longitude. The altitude is about 4,560 feet. 
The station contains about 227 acres. Of this area 160 acres, 
known as the “forestry quarter,’ are owned by the Colorado Agricul- 
tural Experiment Station. The remaining 67 acres, lying directly 
south of the ‘“‘forestry quarter,” are controlled by the United States 
Department of Agriculture. General views of the buildings of the 
station in 1908 and in 1923 are shown in Figures 1 and 2. These 
clearly indicate the growth of the experiment station in the past 
15 years.
