lands of the Mountain States. It is interesting to note that the two 

 best oat varieties are black, one a winter and the other a spring 

 variety. 



BARLEY. 



During 1909 and 1910 two winter and three spring varieties of barley 

 were included in the plat tests. Since 1910 the only barleys tested at 

 Nephi have been winter varieties. Of these, two varieties have been 

 included in the plat tests with winter cereals arid four additional 

 varieties have been included in the nursery tests. The results obtained 

 from the two types (winter and spring) will be considered separately. 



Winter Barley. 



The test with winter barleys began in 1909. During 1909 and 1910 

 they gave a higher average yield than did the spring barleys for the 

 same period, after which the latter were discarded. The inferiority of 

 the spring barleys is due to poorer germination, lower tillering power, 

 and later maturity. The winter barleys have ripened about 10 days 

 earlier than the spring barleys and in that way have more fully 

 escaped drought. 



The best variety of winter barley tested has been the Utah Winter 

 (C.I. No. 592), known also as White Club in some parts of the country. 

 It is of the round or true 6-rowed type, and the head is short, very 

 compact, and club shaped. The straw is very stiff and the heads are 

 erect. The principal objection to the variety is the ease with which 

 the heads are broken off when ripe. The seed of Utah Winter was 

 obtained in 1908 from the Boswell farm, where it had yielded about 

 50 bushels per acre that year. 



The other variety of winter barley included in the plat tests was 

 Tennessee (C. I. No. 257). This is one of the square 6-rowed barleys 

 often called 4-rowed. The head is longer and somewhat nodding and 

 the straw is not so stiff as that of the Utah Winter. Otherwise their 

 habits of growth are similar. They grow to a good height and their 

 quality is excellent. 



The annual and average acre yields of the two varieties are com- 

 pared, together with a summary of the miscellaneous data which have 

 been collected during the past four years, in Table XIII.
