VARIETAL EXPERIMENTS. 
Since 1908 25 varieties and strains of barley have been grown in 
the varietal experiments. Only 1 variety has been grown during the 
entire period, but 4 
varieties were grown 
continuously fro m 
1909 to 1919, inclu- 
sive. The yields are 
shown in Table 
XXII. The average 
yields of 6 varieties 
of barley are also 
shown graphically in 
figure 11. 
In Table XXII it 
can be seen that high 
yields of barley were 
obtained in 1915, and 
fair yields in 1908, 
1909, 1916, 1917, and 
1918. During the 
other seasons the 
yields either were 
small or else almost 
complete failures. 
These differences 
were chiefly influ- 
enced by the seasonal 
precipitation. 
In general the 2- 
rowed varieties have 
produced the highest 
yields. Of the two 
leading 2-rowed vari- 
eties. White Smyrna 
has given the highest 
average yield. Be- 
cause of its earliness 
this variety has yield- 
ed well in dry seasons, 
but the Hannchen va- 
riety yielded best in 
favorable seasons. Heads of Hannchen and White Smyrna barley 
are shown in figure 12. The Odessa is the highest yielding 6-rowed 
77754°— 22 5
