      Clark, Lee J.; Cluff, Ronald E.; Silvertooth, Jeff (College of Agriculture, University of Arizona (Tucson, AZ), 1994-03)
      Two on farm, replicated short staple variety demonstrations were established in 1993. Twelve varieties were evaluated in one location and fifteen varieties were evaluated at the other. Delta Pine 90 was the highest yielding variety at one location with a yield of 1387 pounds of lint per acre and Stoneville LA 887 was the highest yielding variety at the other location with a yield of 1134 pounds of lint per acre.
    • Short Staple Variety Trial, Greenlee County, 1993

      Clark, Lee J.; Silvertooth, Jeff (College of Agriculture, University of Arizona (Tucson, AZ), 1994-03)
      Ten short staple cotton varieties including four New Mexico acalas, one New Mexico experimental acala, three California acalas, one hybrid acala and a rust resistant variety from Mexico were tested in the 1993 variety study. The highest yielding variety was Maxxa with a lint yield of 832 pounds per acre. In addition to lint yields; percent lint, boll weights, plant heights and plant populations are shown. Average boll weights are compared between this location and three other elevations varying from 1400 feet to 4100 feet above sea level.
    • Short Staple Variety Trials in Cochise County, 1993

      Clark, Lee J.; Silvertooth, Jeff (College of Agriculture, University of Arizona (Tucson, AZ), 1994-03)
      Variety trials were grown at two locations and with two different sets of short staple varieties. One trial, north of Kansas Settlement, tested nine acalas and one rust resistant variety from Mexico. The other trial, south of Kansas Settlement and east of Pearce, tested three acalas and nine upland varieties. Top yielding varieties were Maxxa, in the acala trial and DPL 2056 in the upland trial. Yields were lower than expected due to adverse weather conditions, including hail.
    • The Use of AZSCHED to Schedule Irrigation on Cotton, Safford Agricultural Center - 1993

      Clark, Lee J.; Carpenter, Eddie W.; Slack, Donald C.; Martin, Edward C.; Silvertooth, Jeff (College of Agriculture, University of Arizona (Tucson, AZ), 1994-03)
      An irrigation scheduling trial was implemented on both long and short staple cotton on the Safford Agricultural Center in 1993. It is a continuation of studies initiated in 1991, where plots were irrigated when they reached 40 %, 50% and 60% soil water depletion level as predicted by the AZSCHED software. Results for this study are given as well as a summary of the three year study.
