HARD RED WINTER WHEATS IN DRY AREAS 21 
RESULTS AT WILLISTON, N. DAK. 
The Williston substation of the North Dakota Agricultural Experi- 
ment Station is located near Williston, N. Dak., on a fine sandy 
loam soil in the valley of the Missouri River at an altitude of 1 875 
feet. The normal annual rainfall is 15.07 inches. The experiments 
at Williston have been conducted cooperatively by the North Dakota 
Agricultural Experiment Station and the Office of Cereal Investiga- 
tions. They were started in 1908 and discontinued at the close of 
the 1918 crop season. The yields of winter-wheat varieties are 
shown in Table 11. 
The varieties were sown in standing corn or on fallow. Only 
single plats were used except in 1915, when three plats of each variety . 
were grown. 
Eight varieties of winter wheat were included in the experiments 
at Williston during the 8-year period from 1909 to 1916, inclusive. 
Kharkof was not grown during the last three years, so the compara- 
tive yields are for only five years. All varieties were completely 
-winterkilled in 1912. The average yield of Kharkof was 14.3 bushels 
per acre. During the same period Beloglina yielded an average of 
2.5 bushels per acre more than Kharkof, owing to its greater hardi- 
ness. Other hard red winter varieties yielded nearly the same or 
considerably less than Kharkof. Buffum No. 17, a hardy soft red 
winter wheat, yielded more than twice as much as Kharkof in 1913 
and was considerably more productive than Beloglina during the 
period from 1913 to 1916, inclusive.

RESULTS AT MOCC ASIN, MONT. 
The Judith Basin substation of the Montana Agricultural Experi- 
ment Station is located at Moccasin, Mont., on a dark clay-loam 
soil with a gravelly subsoil. It is at an altitude of 4 ,228 feet, and the 
average annual precipitation in 25 years was 16. 51 inches. Cereal 
experiments, cooperative between the Montana Agricultural Ete 
ment Station and the Office of Cereal Investigations, have been 
conducted at Moccasin since 1909. The rads of winter-wheat 
varieties are shown in Table 12.
