BULLETIN 398, U. S. DEPAETMENT OF AGKICULTUEE. 



yields were obtained from all varieties. In 1910 six more varieties 

 were added to the test. Because of tlie shortage of summer-fallowed 

 land it was necessary to grow the varieties on the ground used for 

 testmg barley in 1909. The land was plowed early in the spring and 

 the seeding was done on April 20. The resultmg yields were low. 

 In 1911 the hot, dry weather in. July reduced the yields, and m 1912 

 all varieties were destroyed by hail. In 1913 good yields were ob- 

 tamed from all varieties. The hot, dry weather durmg July, 1914, 

 caused the varieties to ripen early and the quality of the grain was 

 poor. The yields obtained in 1915 were the highest recorded at the 

 station. 



Tlie barley varieties were grown in unreplicated tenth-acre plats 

 in 1908, 1909, 1910, and 1913 and in unreplicated twentieth-acre plats 

 in 1911 and 1912. In 1914 and 1915 they were grown in fiftieth-acre 

 plats, replicated five times. 



Table XXI gives the annual and average yields of the barley varie- 

 ties that have'been tested at Moccasin from 1908 to 1915. Of the 19 

 varieties listed in this table, 9 belong to the 2-rowed huEed group, 

 5 to the 6-rowed hulled group, 2, to the 2-rowed naked group, and 3 

 to the 6-rowed naked group. Only 3 of the 19 varieties have been 

 groTSTi in all seven years and only 14 are now being grown. Heads 

 of representative varieties of the different groups of barley are shown 

 in figure 13.
