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 from 

 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 jdeld- 

 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
