      Six pinto bean varieties were tested in the Bonita area of Graham county with excellent results, three of these varieties yielded over 3000 pounds per acre. These yields coupled with bean values above 30 cents per pound have created considerable interest in growing dry beans in Cochise and parts of Graham county.
    • Forage Production of Four Crops Grown Under Two Different Production Cultures, 1990

      Sheedy, M.; Ottman, M.; Ramage, T.; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      Forage trials of four crops grown under high-input and low-input production cultures were performed at the Maricopa Agricultural Center. Six varieties of each crop were grown to evaluate yield potential under both production cultures. Only a preplant irrigation was applied to the low-input culture, but up to four additional irrigations were applied to the high-input culture. No fertilizer application was given to low-input, but a total of 135#N/A and 75#P₂O₅/A was applied to the full production culture. Barley, durum, and wheat cultivars developed for grain yield under a low-input production culture were tested for forage production under both high- and low-input practices. No advantage in forage production was observed by using the following varieties in a low-input production culture: Stampede oats, Westford barley, Mexicali durum, and 911 wheat produced the highest yields in each of the four crops. Yields were greater from crops grown under a high-input culture: Stampede oats, Harlan II barley, Aldura durum, and 911 wheat were highest yielding varieties in each crop.
    • Shepardspurse Control in Established Alfalfa

      Tickes, Barry R.; Heathman, Stanley; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      A test was conducted on established alfalfa to evaluate the efficacy of 10 herbicide treatments for the control of shepardspurse (Capsella bursa). Control ranged from 13 to 99 percent.
    • Alfalfa Variety Trial in Greenlee County, 1989

      Clark, L. J.; DeRosa, E.; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      Ten alfalfa varieties, ranging from very non- dormant to moderately dormant cultivars, have been grown and yields compared over a four year period No significant differences were noted in the yields for 1989; all varieties yielded over 8 tons per acre in 6 cuttings. Interesting changes are taking place, however, with the very non -dormant varieties continuing their productivity and the more dormant varieties productivity declining.

    • Moisture Loss from Uncovered Stored Alfalfa

      Tickes, Barry R.; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      Moisture loss from stacked alfalfa was measured at various times of the year and at various baling moistures. Total moisture loss over two month time periods varied from 4.5% to 8.3% with considerable fluctuation occurring due to environmental conditions.
    • Alfalfa Variety Demonstration at the Safford Agricultural Center, 1989

      Clark, L. J.; Carpenter, E. W.; Cluff, R. E.; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      Yields by cutting are given for 22 varieties of alfalfa grown at the Safford Agricultural Center. Yields were good in 1989 with 9 of the varieties yielding over 10 tons per acre in 7 cuttings and the top variety yielding 12 tons per acre. Graphs are shown comparing yields by cutting between sister varieties of differing fall dormancy classes.
    • Evaluation of Coated Alfalfa Seed

      Tickes, Barry R.; Ottman, Michael; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      A test was conducted to evaluate the effect of two seed treatments on seven varieties of alfalfa. The treatments included Rhizocote, Rhizocote plus Apron plus Rovral and untreated seed. Significantly fewer seedlings emerged for the coated than the uncoated seed when planted on a pound for pound basis. First cutting alfalfa yields were neither increased nor decreased as a result of the seed treatments.
