CEREAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 89 
to the acre seems to be the best rate to sow. THarly sowing, during 
the first half of September, has given the highest average yields. 
Spring wheats have yielded less than winter wheats. Durum 
wheats have yielded more than spring common wheats. The Belo- 
turka and Kubanka are the highest yielding durum varieties. Among 
the spring common wheats, varieties of the Preston group have 
outyielded Fife and Bluestem wheats. 
Experiments on the rate of seeding durum wheat are not con- 
elusive. So far, 2 pecks of the Arnautka variety have given the 
highest average yields. Sowing early, about the middle of April, 
has given the highest average yields for spring common wheat. 
In experiments with oats the early varieties, Kherson and Sixty- 
Day, have given the highest average yields in two of the three 
years. In 1915, a cool, wet year, midseason varieties were better. 
The Swedish Select has given the highest average yield in the 
3-year period. 
Kherson oats sown at the 6-peck rate yielded better than when 
sown at lower rates. Early seeding, about the middle of April, 
has given the best results. 
Experiments with spring barley show that the White Smyrna and 
Hannchen, both 2-rowed bearded hulled varieties, have given the 
highest average yields. 
The Svanhals barley sown at the rate of 2 pecks and 3 pecks per 
acre has yielded more than when sown at higher rates. The same 
variety has given the best yields when sown rather early, from the 
middle to the latter part of April. 
Compared with wheat, the yields of spring oats and-barley have 
been rather low. Winter oats and winter barley have been failures. 
Varietal experiments with flax show Montana Common and Select 
Russian to be the best varieties. Sowing at the rate of 15 pounds 
per acre has given the highest average yield, and sowing about the 
first of June has proved better than earlier seedings. 
Neither winter nor spring emmer has proved of value. Foxtail 
and proso millets have given only low yields. Buckwheat does not 
appear promising. 
Grain sorghums and corn are promising forage crops for roughage 
or silage, but apparently have little or no value as grain crops. 
The following varieties of the principal grain crops apparently are 
best for this district: , 
Winter wheat.—Ghirka and Kharkof or Turkey. 
Spring wheat.—Kubanka, Erivan, Marquis. 
Spring oats.—Kherson, Sixty-Day, Swedish Select. 
Spring barley.—White Smyrna, Hannchen. 
Flax,—Montana Common, Select Russian,
