      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.
    • 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.
    • 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.
    • Stand Longevity of 13 Alfalfa Varieties Grown on the Yuma Mesa

      Tickes, Barry R.; Ottman, Michael; Ottman, Michael; Bantlin, Marguerite (College of Agriculture, University of Arizona (Tucson, AZ), 1990-09)
      The stand longevity of 13 alfalfa varieties was evaluated 3 years after planting. The number of crowns per acre ranged from 71,000 to 163,000.
