The experiments at Highmore were conducted in single plats; 
consequently the variations in yield are rather large. Kanred during 
two seasons produced significantly higher yields than Kharkof. 
Two other lots of Kharkof (C. I. Nos. 1583 and 4207) and Turkey 
(C. I. No. 3689) produced slightly higher yields than the standard 
Kharkof, C. I. No. 1442, during the 5-year period. 
RESULTS AT DICKINSON, N. DAK. 
The Dickinson substation of the North Dakota Agricultural 
Experiment Station is located on the border of the Heart River 
Valley, near Dickinson, N. Dak., on a soil varying from sandy loam to 
clayloam. The altitude is 2,453 feet, and the average annual precipi- 
tation has been 15.29 inches in a 3l-year period. The varietal 
experiments conducted cooperatively by the North Dakota Agri- 
baltitad Experiment Station and the Office of Cereal Investigations 
were started in 1907, but data from winter wheat in plats have been 
obtained only since 1913. The yields obtained are shown in Table 10. 
The varieties were sown in standing corn each year except 1914, 
when they were sown on fallow. Single plats were grown from 1913 to 
1918 and duplicate plats from 1919 to 1922. All varieties were winter- 
killed in 1918 and 1920, although the Beloglina variety, which also 
was sown in wheat stubble, in 1918 partly survived the winter and 
yielded 5.2 bushels per acre. Owing to heavy winterkilling and 
drought the yields at Dickinson have been low in most seasons. Two 
varieties, Kanred and Turkey (C. I. No. 3084), have slightly out- 
yielded Kharkof, but not significantly. 
TaBLe 10.—Yields from 10 varieties and strains of winter wheat grown at the Dick- 
inson substation, Dickinson, N. Dak., during the 10-year period from 1913 to 
1922, inclusive, compared with those of Kharkof in comparable years
