CEREAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 25 
EXPERIMENTS WITH EMMER AND SPELT. 
One variety each of winter and of spring emmer has been grown 
at Archer during the 3-year period, 1913 to 1915, inclusive. 
WINTER EMMER. 
Black Winter emmer has been tested each year. In 1912 a tenth- 
acre plat was sown and about 50 per cent survived the winter. This 
plat yielded at the rate of 14.2 bushels per acre. In 1913 several 
plats were seeded at different rates. Thestands and fall growth were 
good on all plats, but the crop entirely winterkilled. In 1914 three 
twentieth-acre plats were sown to winter emmer at different rates. 
A fair stand was obtained and the winter survival was high. The 
average yield of the three plats was about 20 bushels per acre. 
Winter emmer has not survived the winters as well as winter wheat 
and the yields have been much lower. Winter emmer evidently is 
not adapted to conditions on the high western plains. The average

yields of emmer at the Cheyenne Experiment Farm have been lower 
than those of either spring oats or barley. 
Winter emmer is drought resistant, but it is not nearly so hardy 
as the Crimean group of winter wheats. The data available indicate 
that Black Winter emmer is a doubtful crop in eastern Wyoming 
and growing it should not be encouraged at present. 
SPRING EMMER. 
White Spring emmer has been grown at Archer in each of the three 
years, 1913 to 1915, inclusive. In 1913 a tenth-acre plat was sown. 
The stand obtained was too thick and the growth was short. The 
plat yielded at the rate of 7.2 bushels per acre. In 1914 a tenth-acre 
fallow plat was sown. On this plat the stand was very thick and the 
growth was short, yielding at the rate of 13.4 bushels per acre. In 
1915 three twentieth-acre plats were sown at the rate of 3, 4, and 5 
pecks per acre on the barley scale. Under the favorable conditions
