 grass should be a satisfactory crop. Under dry-farming soy beans, 

 cowpea.'^. and velvet beans were failures.

 Under this project plantings were made on the five farms under 

 control of the University. In all, 12 varieties of vetch were tested, 

 10 varieties of cowpeas, 4 of soy beans, 3 of velvet beans, 4 of 

 clover. A considerable number of miscellaneous crops were tried 

 out on a small scale. In the Yuma Valley a number of the varieties 

 of vetch were very promising, practically every one of them making 

 a satisfactory growth and producing seed. In the Salt River Val- 

 ley an unusually sharp frost occurred just after the vetches were 

 up, and every variety, either from this or some unknown cause, 

 died. 



Of all the varieties of cowpeas tested, Red Ripper seems the 

 most desirable. Groit stands second. From the standpoint of 

 foliage alone, Brabham is perhaps as desirable as either of the other 

 two. However, the Brabham variety produces seed very sparingly, 

 consequently its usefulness as a field crop is limited. The Taylor 

 variety was good in the Salt River Valley, but Whippoorwill gave 

 only medium success.
