small grains 



It has been considered advisable to discontinue most of the 

 variety tests of small grains which have been carried on at the 

 Phoenix Farm for a number of years. In attempting to standardize 

 these crops work for the last fiscal year has been Hmited to the 

 Early Baart variety of wheat, Texas Red and San Saba oats, Wis- 

 consin No. 6, and common six-row barley. Where available, se- 

 lected seed was planted under commercial conditions in order to 

 increase the quantity of desirable seed which could be placed upon 

 the market for the benefit of Arizona farmers. 



The wheat yielded from forty-one to fifty bushels per acre and, 

 with the high prices of the present season, returned very handsome 

 profits. The oat yields varied from ninety-three to over one hun- 

 dred bushels per acre, and the barley, which had been lightly pas- 

 tured, from forty to sixty-five bushels. 



A new variety known as Wisconsin No. 6 pedigreed barley was 

 tried out during the past fiscal year with rather unsatisfactory re- 

 sults. A very large yield of grain was produced from this variety, 

 but the breaking olif of the heads grea'ly diminished the amount 

 harvested. 



LEGUMES 



About twenty acres of Hairy Peruvian alfalfa and ten acres of 

 the common strain were grown with results favoring the former. 



Ten varieties of cow peas and fourteen varieties of soy beans 

 were planted in May. These crops, which have been little grown 

 in Arizona, gave promising results and the indications are that they 

 will sometime become very valuable plants in the Southwest. While 

 the available data are meagre, indications are that cow peas may 

 be quite successfully planted at almost any time after danger of 

 frost is over until there is barely sufficient growing season left 

 for their maturity. Soy beans, on the other hand, should be planted 

 on the latest date in the season which will allow them time for 

 maturity before frost. With the larger and longer season varieties 

 this date should be from the middle to the last of June and the 

 earliest varieties may be planted as late as the first of August. 

 Since the seed of this crop bids fair to become an important source 

 of a partial substitute for linseed oil the possibilities of its culture 

 are a matter of interest. 



Among the more promising varieties of cow peas, Red Ripper. 

 Two Crop Clay, Iron, and Clay may be mentioned. Desirable early
