DRY-LAND GRAINS IN THE GREAT BASIN.

years' results are obtained no positive statements regarding their 

 yielding power can properly be made. 



SPKING BARLEYS. 



Two varieties of spring barley, the California and the California 

 Prolihc, have been grown at the substation for six years. One 

 other, a hull-less, beardless variety, was tested in 1907, 1908, and 

 1909. The average yields of these are given in Table VII.

As shown above, there is practically no difference between the 

 yields of the California and California Prolific barleys. The two 

 strains are botanically identical also. The Hull-less variety has 

 been a very poor yielder. All three have very short straw. They 

 grow about 6 inches shorter than the winter barleys, and are for 

 this reason very difTicult to harvest with either binder or header. 

 It is believed that the winter varieties, especially the Utah Winter 

 barley, will be foimd preferable as dry-land crops for the Great Basin 

 area. 



WINTER EMMER. 



Emmer is one of the least-known grains in the United States. 

 Botanically it is closely related to wheat, but its position in farm 

 economy is more nearly like that of barley, since it is valuable princi- 

 pally as a stock food. It resembles barley also in that the glumes 

 (chaff) adhere to the kernel when the grain is thrashed. There 

 are both winter and spring varieties, but only a winter variety, 

 Black Winter emmer, has been tested on the substation plats. Its 

 ability to resist drought has been satisfactorily demonstrated and at 

 Nephi it has proved extremely hardy. 



In 1908 it yielded 41.33 bushels per acre; in 1909 the yield was 

 43.66 bushels, the 2-year average being 42.49 bushels per acre. 

 The grain weighs about 30 pounds per measured bushel. Although 

 its feeding value is not definitel}' known, it is thought to be about 

 equal to that of barley and is much relished by horses, hogs, and 

 sheep. The hardiness and drought resistance of Black Winter
