DRY-LAND GRAINS IN THE GREAT BASIN. 



Table VI . — Yield to the acre of six varieties or strains of spring oats grovm at Nephi, Utah, 



from 1904 to 1909, inclusive. 



a Bulletin 100, Utah Agricultural Experiment Station. 



Table VI shows that the Black American stands first among the three 

 varieties grown during the past six years and that the Giant Yellow 

 is slightly superior to the Nephi strain of Sixty-Day. Although the 

 Highmore strain of Sixty-Day and the Swedish vSelect have been tried 

 only two years it is believed that they will prove better yielders 

 than the Black American or the Giant Yellow. Whether this is 

 true can be determined only by further testing. 



The vSwedish Select and the vSixty-Day have the advantage of the 

 Black American in the matter of color, and they are far superior to 

 the Giant Yellow in uniformity of ripening. This is very much in 

 their favor. In the matter of earliness the Kherson and the Sixty-Day 

 lead. They ripen 10 to 15 days earlier than the Swedish Select, 10 

 days earlier than the Black American, and 15 days earlier than the 

 Giant Yellow. The Swedish Select grows from 26 to 36 inches tall, 

 depending on the season ; the other varieties all average about 6 inches 

 shorter. Until additional data are secured it will not be possible to 

 state positively whether the spring oat varieties will be better 

 than the winter oat, but it is believed that when the latter becomes 

 thoroughly winter-hardy it will excel those planted in the spring. 



WINTER BARLEYS. 



Only one year's results have been obtained with winter barleys, 

 Utah Winter barley (G. I. No. 592) was tested in 1909. The seed 

 of this variety- was obtained from the Boswell farm, where it pro- 

 duced about 50 bushels per acre in 1908. In 1909 the yield at the 

 substation was 25.9 bushels per acre, a very satisfactory yield for 

 such a dry season. The other winter barley tested in 1909 at the 

 substation is Tennessee Winter (G. I. No. 257). It yielded 18.1 

 bushels per acre. These two barleys grow from 25 to 30 inches tall, 

 and ripen 10 days earlier than the spring barleys. Their quality 

 is excellent. It is thought that further testing of these varieties will 

 prove their right to recognition as dry-land crops, but until several
