EXPERIMENTS WITH BARLEY. 
WINTER BARLEY. 
Only one variety of winter barley has been tested at Archer, and 
that in only one year. On September 11, 1913, a tenth-acre plat was 
sown to White Club barley. A good stand and a fair fall growth 
resulted. The crop was entirely killed during the ensuing winter. 
Winter barley is not nearly as hardy as winter wheat, and it is 
hardly probable that it can be grown successfully in the Great Plains 
area. 
SPRING BARLEY. 
Spring barley is grown quite extensively in Wyoming, both in irri- 
gated and dry-farmed sections. 
VARIETAL EXPERIMENTS. 
-At Archer 14 varieties of spring barley have been tested in the 
three years, 1913, 1914, and 1915. The annual and average yields 
of these varieties are shown in Table XX. In 1913 the barley 
varieties were grown in single tenth-acre plats on fall-plowed break- 
ing, in 1914 in single tenth-acre plats on spring-plowed fallow, and in 
1915 in duplicate twentieth-acre plats on double-disked corn ground. 
Good stands have resulted each year. In 1913 the summer was dry 
and yields low. The White Smyrna (C. I. No. 658) yielded best, 10 
bushels per acre. In 1914 the growing season was dry and the yields 
low, although somewhat higher than in 1913. The White Smyrna 
(C. I. No. 658) again was the highest in yield, producing 16.3 bushels 
per acre. In 1915 the spring and summer rainfall was high and the 
yields good. For the third successive year the White Smyrna pro- 
duced the highest yield, 38.3 bushels per acre.
