• Corn Variety Trial in Bonita, Graham County, 1986

      Clark, Lee; Cluff, Ronald, E.; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)
      Fourteen corn hybrids were tested, only one of which had previously been evaluated in University tests. Yields, stands, moisture in the grain at harvest, net value of the crop (after subtracting drying costs) and other agronomic data were determined. The top -yielding hybrid, Pioneer 3183, produced 11,942 pounds per acre but produced about $2 per acre less than the highest valued variety, DeKalb 656, which produced $460.54 per acre.

      Clark, Lee; DeRose, Edith; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)
      Ten varieties of 115 to 125 day corn hybrids were tested in an on going variety trial in Greenlee county. Drying costs were also calculated to not only determine the top- yielding variety but also the variety having the highest net value after subtracting drying costs. Pioneer 3183 ranked top in both categories.
    • Late Corn Variety Trial in Greenlee County, 1986

      Clark, Lee; DeRose, Edith; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)
      Five corn varieties with maturities varying from 95 to 108 days were grown in a double crop situation following barley. The variety that produced the highest net value (after deducting drying costs) yielded only $194.39 per acre, slightly less than the marginal cost of production.
