SMALL GRAINS ON ARLINGTON EXPERIMENT FARM 
25 
Six-rowed varieties of bailey have produced the highest yields. 
Anew strain of Orel, a 2-rowed barley added to the varietal experi- 
ment in 1918, is now showing promise, having outyielded all varieties 
during the 6-year period from 1918 to 1923, inclusive. The 6-rowed 
barleys which have yielded best are Wisconsin Winter (C. I. No, 
2159)", Han River (C. I. No. 2163), Pidor, Scottish Pearl, and Ten- 
nessee Winter. The Nakano Wase strains are awnless and have in 
certain years produced good yields, but their very rapid fall growth 
makes them likely to winterkill. They were entirely killed in the 
winter of 1917-18, when the weather was unusually cold. Nakano 
Wase appears to be resistant, however, to both the loose and covered 
smuts. Plate III shows typical heads of three varieties of winter 
barley grown at the Arlington Experiment Farm, and Plate IV shows 
several of the varietal plats of barley just at the beginning of harvest.

Table 18 shows further agronomic data for five varieties of barley 
grown during the 7-year period, 1915-1921, inclusive. The early ma- 
turity of the crop is shown, ripening in sufficient time to harvest before 
wheat or oats. Nakano Wase is an especially early barley, usually 
ripening about one week before Tennessee Winter. Wisconsin Winter 
matures late, but produces very high yields. The bushel weights of 
all varieties except Hansee and the Nakano Wase strains have been 
low, owing to the persistence with which the awTi remains attached 
to the lemma. In certain years this condition is much more pro- 
nounced than in others, owing possibly to w^eather conditions about 
harvest time. The presence of the awns also causes difficulty in.
