      Aldura, Westbred Turbo and Westbred 881 were grown in four sites in three counties (Graham, Greenlee and Cochise) in southeastern Arizona to determine which would produce the largest income per acre. At an assumed 75 cent premium for Westbred 881 over a base of $5.25 per hundredweight, Aldura and Westbred Turbo generally out produced Westbred 881. Relative yields of the three varieties are shown for all locations.

      A wheat and barley test on the Bruce Church Ranch, Poston, Arizona, La Paz County, harvested June 8 & 9, 1987, gave crop and variety performance differences under grower management conditions. The top yielding barley variety was Fiesta, 6990 lbs /ac. The leading durum varieties were Turbo, Gem and Aldura. Durum wheat Westbred 881 was highest in protein (13.7 %). In red wheat varieties, yields ranged from 4660 to 5750 lbs/ac. The top three varieties were Baker, Probred and Yecora Rojo. Baker was highest in protein (14.6 %), followed by Yecora Rojo (14.2%). Continued testing over several years is necessary to assess variety performance under grower management conditions.

    • Winter Wheat Variety Trial in Cochise County, 1987

      Clark, Lee; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)
      Sixteen winter wheat varieties (including three hybrids) were evaluated in a randomized, complete block experiment, with four replications. Stephens, the standard variety grown in the area, was outyielded by four of the winter wheat cultivars, including two of the hybrids. The highest yielding cultivar was a hybrid, Bounty 100, which yielded 5853 pounds per acre (23% higher than Stephens).
