CEREAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 1S) 
enough the next spring to make fair yields. The rainfall during the 
erowing season was below normal. 3 
In 1914, 15 varieties and strains of winter wheat were grown in 
tenth-acre plats on fallow land. The land was plowed in the fall of 
1912 and left rough until the spring of 1913, when it was double- 
disked and kept free from weeds during the summer. The varieties 
were sown September 9, 1913. The fall of 1913 was wet, and good 
stands of all varieties were obtained. The winter wheats were 3 to 6 
inches high when winter began. The winter was cold and open, and 
practically all varieties winterkilled considerably. A few plats 
apparently were favorably located, and on these the winter survival 
was much higher than on the others. The winterkillng was not 
uniformly distributed on the plats, but occurred in patches or streaks. 
The survival of a variety did not necessarily indicate winter hardi- 
ness, since the same variety sown on different plats had a markedly 
different winter survival. However, certain soft winter wheats less 
hardy than those of the Crimean group were entirely winterkilled. 
It is believed that the yields reported in Table VI are representative 
of what could reasonably have been expected from winter wheat on 
fallow land in 1914, as winterkillng was quite general on farms in 
the vicinity. The precipitation for the growing season was below 
normal, as shown in Table I.
