Table XIII shows that Utah Winter is the better of the two 

 varieties in almost every instance. The average stand of this 

 variety is considerably better than that of the Tennessee Winter, 

 and it has ripened an average of one week earlier. The yield of the 

 Utah Winter is noticeably better than that of the Tennessee Winter. 

 The latter variety as a dry-land crop has a little advantage in ratio 

 of grain to straw. 



Spring Barley. 



Two varieties of spring barley, California and California Prolific, 

 were grown for seven years at the substation previous to 1910. The 

 average acre yield of these varieties for the years 1904 to 1906, 

 inclusive, 1 was 24.3 and 22.4 bushels, respectively. One hooded 

 hull-less variety was tested in addition to the two bearded varieties 

 named above, in 1908, 1909, and 1910, after which they were dis- 

 carded. Their annual and average yields for 1908 to 1910, inclusive, 

 are presented in Table XIV.
