months previous. The farm promises to produce sufficient silage 

 to fill the silos on the farm and provide facilities for experimental 

 feeding of beef or other cattle. 



In furthering the work of this farm, plans are being prepared 

 and work will soon begin on the construction of a general barn 

 whicli will cost api)roximately S2500. 



11. continuation Ol' STUDIES AT SULPHUR SPRING VALLEY DRY-FARM 



Due to the very dry winter of 1919-1920, small grains planted 

 in the fall of 1919 did not make profitable yields in the spring of 

 1920. From the farmers' standpoint, our experiments with Early 

 Baart wheat, ]\Iacaroni wheat, ]\Iarquis wheat, common six-row 

 barley, Abruzzi rye, and Red Texas oats would all be recorded as 

 failures. Two plantings of each of these crops were made, good 

 stands were secured, and the failure was due wholly to dry weather. 

 In the spring of 1920 the regular plantings of field crops such as 

 Mexican June corn, liickory King corn, Papago Sweet corn, milo, 

 hegari, Freed's sorghum, Red Amber sorghum, darso, and Tepary 

 beans were made. On June 30 all of the crops of the Experiment 

 Farm were in very i)oor condition, due to the extremely dry winte--, 

 spring, and early summer. Although Papago Sweet corn produced 

 a perfect stand, and, early in the spring, grew well until it reached 

 a height of approximately two feet, it practically ceased to grow at 

 this point and on June 30 is beginning to head out at a height of 

 two feet. From a practical standpoint this crop would not pay 

 for harvesting. 



Darso sorghum planted in ]\Iarch and given as good conditions 

 as it was possible to give undei dry-farming methods, has failed to 

 germinate ; following the first rain in the month of July, the field 

 will be replanted to quicker maturing sorghums. 



III. LEGUMES AND TllEiR CULTURE EOR SOUTHWEST CONDITIONS 



Under this project plantings were made on the five farms of 

 the Experiment Station. The major part of these plantings, how- 

 ever, were made on the Salt River \'alley Farm near Mesa. 

 Several varieties of vetch were planted, the most profitable in this 

 particular season being bitter vetch. One acre was planted in the 

 fall of 1919 to garbanzas (chick peas). This crop made a reason- 

 ably good forage growth, reaching a height of approximately 

 twenty inches. I-Iowever, the yield of seed was comparatively 

 light, l)eing estimated at six or eight bushels per acre; because of 

 the light seed yield, this crop was harvested for hay during the 

 month of May.
