DRY FARMING IN SOUTHEASTERN WYOMING 19 
killing and soil blowing. It may be possible to deYelop cultural 
methods that will reduce substantially the losses from these causes. 
The 10-year average yield of oats from all plats was 16.9 bushels to 
the acre. The highest average acre yields were obtained following 
corn, both disked and spring-plowed corn ground averaging 20.3 
bushels. The lowest yields were from plats cropped continuously to 
oats. The average yields of these plats were less than 12 bushels to 
the acre. 
The average acre yield of barley was 12.6 bushels. The highest 
yield, 18.6 bushels, was on fallow. The next highest yield, 15.1 
oushels, was on disked corn ground. Plats cropped continuously to 
barley averaged from 9.1 to 12.3 bushels to the acre. 
Flax did not produce satisfactory average yields, largely on account 
of its inability to compete with weeds, particularly with the Russian- 
thistle. 
Corn proved a fairly reliable crop for both grain and forage. The 
use of an early variety is essential to the production of grain. The 
average yield of all plats was 15.9 bushels of grain and about 1,800 
pounds of stover to the acre. The average yield of corn was not as 
high on fallow as it was when grown by several other methods. 
Contrary to the results with small grains, continuous cropping to 
corn except on the listed plat produced relatively good yields. The 
yield of stover averaged 114 pounds to the bushel of grain. 
Yields of all crops were generally better on spring plowing than on 
fall plowing. 
Subsoiling did not prove an advantageous or profitable operation. 
Experiments on rate of seeding indicate the desirability of seeding 
at the following rates to the acre : Spring wheat, 3 to 4 pecks ; winter 
wheat, 3 pecks on fallow and from 4 to 5 pecks on stubble; oats, 5 
to 6 pecks: barley, 4 pecks; and flax, 15 to 25 pounds. 
Experiments on date of seeding show that spring grains should 
not be sown later than the middle of May and winter grains about 
September 1. 
The choice of crops and varieties that evade or resist drought, 
storms, and diseases may contribute much to success. 
The danger of complete loss in any season may be greatly mini- 
mized by dividing the acreage between crops that make their prin- 
cipal growth in different parts of the season and mature at different 
times. This may be accomplished by the use of spring grains, 
winter grains, corn, and such crops as millet and Sudan grass. 
The production of corn is essential to the most economical pro- 
duction of small grains. Corn provides feed for livestock, and if the 
full value of it is to be realized it is necessary that it be fed on the 
farm. The growth of corn thus makes possible the production of 
small grains and the maintenance of livestock. Such a combination 
decreases the hazards of both the livestock and the grain production 
and tends to the maintenance of a stable agricultural population.
