26 BULLETIN 1276, U. S. DEPARTMENT OF AGRICULTURE 
RESULTS AT ABERDEEN, IDAHO 
The Aberdeen substation is located in the Snake River Plains of 
southern Idaho on a sandy clay-loam soil containing some yolcanic- 
ash material. The altitudeis 4,400 feet. The average annual precipi- 
tation in 11 years has been only 9.33 inches. The substation is main- 
tained cooperatively by the Idaho Agricultural Experiment Station 
and the Office of Cereal Investigations. The results obtained at 
Aberdeen are presented in Table 14. 
The varieties were grown in single plats in 1913 and 1914, in dupli- 
cate plats in 1915, and in triplicate plats from 1916 to 1918, inclusive. 
Yields of winter-wheat varieties were obtained during six seasons. 
The crop was almost a failure in 1916, 1917, and 1918. Kharkof was 
not grown in 1917, but the 5-year average yield of this variety was 
17 bushels per acre. Only one variety, Turkey (C. I. No. 1571), 
outyielded Kharkof by an average of more than 1 bushel per acre. 
The slightly higher yields of this as well as of a few other varieties 
are not significant. 
TABLE 14.—Yields of 27 varieties and strains of winter wheat grown at the Aber- 
deen substation, Aberdeen, Idaho, during the 6-year period from 1913 to 1918, 
inclusive, compared with those of Kharkof in comparable years
