TESTS AT AKRON. 
The results of only one year are available from the station at Al?Ton, 
Colo. The crop was grown without irrigation. Plantings were made 
in 1912, 1913, and 1914. In 1913 the crop was so nearly a total failure 
on account of injury from drought that no yield records w^ere secured. 
In 1914 a partial crop was developed, but the stands secured w^ere so 
irregular that the results are not considered worthy of presentation. 
Tlie variety miits in 1912 were single-row plats 175 feet long and 
3^ feet wide, makmg an area of about one seventy-first of an acre. 
Plantings were made in hills 3| feet apart at three different rates, 
one, two, and three per hill. The two-per-hill section was planted 
m duplicate. The variety rows were alternated with check rows all 
planted with Swadley corn. 
The yields in pounds of ears for each plat are shown in Table VI. 
The yields in bushels per acre and the rank and class of each variety 
are showaa in the summary. 
The highest yields w^ere secured from the thickest plantings. The 
lowest }T.eld was secured from the one-per-hiU rate and the highest 
yield from the three-per-hill rate. The yield at the two-per-hill 
rate was intermediate between the other two rates, but nearer the 
yield from the three-per-hill rate. It should be borne in mind 
that this season was more favorable than normal, and the results 
obtaiaed should not be interpreted as indicating that stands of 
three stalks per hiU will produce best in average years. Rates 
thicker than two stalks per hill with the hills 3J feet apart each w^ay 
are not recommended for dry-land plantings. There is less differ- 
ence between the yields from different rates of varieties which sucker 
profusely than betw^een rates of nonsuckering varieties. The White 
Australian and Red Squaw produce a large number of suckers, 
while the dent varieties produce but few.
