418 Thirtieth Annual Report 



As has been the case in previous years, soy beans were not 

 satisfactory ; although a good vine growth was secured with most 

 of the varieties, practically every variety, if it produced seed at all, 

 produced a shrivelled and unmarketable bean. This is probably 

 due to the very hot and dry atmosphere, as shrivelled beans were 

 produced regardless of the supply of moisture in the ground. Soy 

 beans cut a little before maturity and allowed to cure in the shock 

 produced a much better quality of beans than those allowed to cure 

 on the vine. 



IV. A STUDY OF THE VARIETIES AND METHODS OF CULTIVATION OF 

 INDIAN CORN AND THE VARIOUS SORGHUMS. 



In handling this project plantings were made on the five 'farms 

 under the control of the Experiment Station and on farms of 

 numerous individuals throughout the State. In the Salt River 

 Valley, Mexican June corn or improved strains of it proved the 

 best of all the varieties tested. The large, coarse, and late maturing 

 corns of the eastern states were very unsatisfactory ; none of them 

 were able to withstand the hot and dry atmosphere of our valleys. 



In the Salt River Valley, milo maize ranked first as a grain- 

 sorghum crop with hegari as a close second. Either of these crops 

 can be planted after a small-grain crop such as wheat or barley, and 

 still have time for complete maturity. Yields in excess of 4,000 

 pounds of threshed grain per acre were secured with both milo and 

 hegari. 



From the silage standpoint, orange sorghum gives promise of 

 being our best variety. Sumac sorghum promises to rank a close 

 second. Honey-drip sorghum and goose-neck sorghum will make 

 larger yields than the tw^o first named, but they are larger, coarser, 

 and more difficult to handle and require a longer growing season. 



v. THE CULTIVATION AND FIELD MANAGEMENT OF EGYPTIAN COTTON. 



All of the experiments in connection with this project were 

 handled on the Salt River Valley Experiment Farm. The work 

 covered date of planting tests ranging from March 1st to May 15th. 

 It covered a series of fertilizer tests in which acid phosphate, sodium 

 nitrate, cottonseed meal, commercial fertilizer, and barnyard ma- 

 nure were used at various rates and in various combinations. Nt> 

 striking nor conclusive results were secured from the fertilizer 

 tests. The various tests in the spacing of cotton were consider- 

 ably injured by a severe storm in late August and the results were 

 not conclusive. A few preliminary experiments were made with 

 the topping of cotton. Excellent results were secured in the con-
