Arizona Agricultural Experime;nt Station 267 



planting- in July after the rains appear, the Sulphur Spring Valley 

 farmer is amply provided with crops of this kind. The above crops of 

 kafir antl feterita were grown on some of the poorest soil on the farm. 

 This particular portion of the farm is underlaid with clay and caliche 

 at a depth of 18 to 24 inches and the water holding capacity of the soil 

 is very low. In some seasons this portion of the farm receives copious 

 floodings from an arroyo that comes down from the country above, but 

 this year no such flood water was obtained. 



Saccharine sorghiiiiis: Club-top cane and Black Amber cane 

 were each planted on three dates: April 15, May 18, July 21, respec- 

 tively. The Black Amber cane made a very poor showing in all of the 

 plantings. The Club Top cane produced two tons of green silage per 

 acre with the April 15 planting and 3.5 tons with the July 21 planting. 

 July planting, however, was immature when harvested. The grain 

 sorghums are superior to the canes for silage purposes, and, since the 

 results indicate greater tonnage from the grain sorghums, there is 

 little reason for the growing of the forage canes. 



Corn: Six varieties of corn were tested. Plantings \Yere made 

 with each variety on three separate dates: April 16, May 15, and July 

 22, respectively. The April and May plantings resulted in very im- 

 perfect stands on account of insufficient moisture in the seed bed ; while 

 the July 22 planting did not afiford ample time for complete maturity of 

 the larger growing varieties, such as Mexican June. The Mexican June 

 vvith each date of planting was superior to the other varieties tried, and 

 appears to be a very excellent variety to grow under these dry farming 

 conditions. The other varieties used in the trials were White Flint, 

 Freeds, White Moqui, Mohave, and Papago Sweet. The April plant- 

 ings of Mexican June yielded four tons of green silage per acre, and an 

 estimated yield of 2490 pounds of grain in the ear per acre. The July 

 planting of Mexican June was immature at the time of harvesting, but 

 yielded 11,520 pounds of green silage per acre. The size of the corn 

 plats varied from one-half to one acre. The smaller Indian corns did 

 not equal the yields of the larger growing varieties this year, but in 

 all probability in years of limited rainfall they would give returns when 

 the larger growing corns would be a failure. 



Canada field peas: Three acres of Canada field peas were sown 

 February 29. The crop was a failure for two reasons, — heat and grass- 

 hoppers. The moisture conditions were good and the peas germinated 

 well giving a perfect stand. When the peas reached a height of seven 

 inches they stopped growing and stood at this size for several weeks 

 imtil the grasshoppers eventually devoured the crop.
