144 THE SMALL GRAINS 



Both two-row and six-row barleys are grown, including 

 hulless and hooded varieties. In general, the two-row 

 barleys do better in the northern portions of the district 

 and the six-row in the southern portions. On a weight 

 basis, the hulless varieties often yield best. In Utah 

 and southern Idaho, a winter variety, the Winter Club, is 

 grown considerably. At the Nephi, Utah station, how- 

 ever, Coast barley yielded better than any winter variety. 

 Throughout the district an established crop rotation is 

 needed, including a suitable intertilled crop to precede 

 barley and other small cereals (Fig. 48).

134. Pacific Coast barley district. Included in this 

 district is all the Pacific Coast territory from British 

 Columbia to California and southern Arizona. 'The con- 

 ditions amply justify a separation into a North Pacific 

 and a South Pacific section, divided at about the head of 

 the Sacramento Valley. In the northern section, how- 

 ever, there is a very small barley production, and the 

 varietal adaptation is so uncertain that it is not worthy 

 at present of a discussion as a separate barley district. 

 The rainfall is very great generally, and the temperature 

 lower than in the southern section, and probably in future 

 a distinct varietal adaptation will be determined. Coast 

 barley seems to be the variety now most commonly grown.
