DRY FARMING IN SOUTHEASTERN WYOMING 
13 
subject it must be remembered that, although the grain yields are of 
great importance, the stover yields should be given more considera- 
tion than in sections where the production of forage is not so impor- 
tant. In order to make profitable use of the corn crop and of the 
lands not suited to tillage, livestock is necessary to farm operations. 
The closeness of the dry farms to the ranges is an asset of which advan- 
tage will no doubt be taken in the future. 
The annual and average yields of corn by different methods are 
given in Table 7 and the averages shown graphically in Figure 8. 
Spring plowing produced higher yields than fall plowing. Spring- 
plowed barley stubble produced the highest 10-year average yield, 
19 bushels per acre. Sp ring-plowed spring- wheat land produced an 
average of 17.4 bushels per acre. Contrary to the results from con- 
tinuous cropping with the small grains, corn produced rather high 
yields on plats continuously cropped to corn except on the listed plat. 
Subsoiling produced an average acre yield of 17 bushels of corn, list- 
ing 11.4 bushels, and summer fallow 17.2 bushels. Spring-plowed

Tig. 8.— Average acre yields of corn grown by different methods at the Archer Field Station for the 10 
years from 1914 to 1923, inclusive. The averages following winter wheat, fall plowed, flax, fall plowed, 
and flax, spring plowed, are for the 9 years from 1915 to 1923, inclusive 
corn stubble produced an average yield of 16 bushels. This is 0.8 
bushel less than the average of all spring-plowed plats. Continuous 
corn on fall plowing produced an average yield of 14.7 bushels per 
acre, or 1 bushel more than the average of all fall-plowed plats. 
Farmers report good results by listing wheat stubble, but listed corn 
is generally a little later and smaller than surface-planted corn. 
Where the seasons are short and it is desired to cut the crop with a 
binder, these factors may become decisive. 
^The yields of stover follow fairly closely the same order as those of 
grain, averaging 114 pounds to 1 bushel of grain, equal to about 
1,800 pounds per acre. 
During the years 1913 to 1915 Brown County Yellow Dent corn 
was grown on these plats. It was found to be rather late in maturing 
and was replaced by Northwestern Dent in 1916. In 1919 Swadley 
Yellow Dent from the Akron (Colo.) Field Station was introduced 
into this experiment and was used during 1919 and 1920. This corn 
is somewhat later than Northwestern Dent, and the ear is placed
