CEEEAL EXPEEIMENTS ON THE CHEYEJSnSTE EXPERIMENT FARM, 25 

 EXPERIMENTS WITH EMMER AND SPELT. 



One variety each of winter and of spring enimer 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. The stands and fall growth were 

 good on aU 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 EMMEK. 



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 yi(!ld(3d at th(! rate of 7.2 busliels per acre. In 1914 a tenth-acre 

 fuUow pljit was sown. On this plat the stand was very thick und the 

 growth was short, yielding at th(^ rate of 13.4 bushels per acre. In 

 1915 three tw(!nti<itli-acr<! plats were sown at th(^ rate of 3, 4, and 5 

 pecks per ucix! on tlx' barley scale. Under \\w. l.-ivonible conditions
