      Several upland cotton varieties and one Pima cotton variety were planted and watered up after Poco barley and Yecora Rojo wheat on the Safford Experimental Farm in 1983. Three upland varieties were planted and watered up on July 2. McNair 235 produced the most lint for all three late planting dates. Pima cotton produced the lowest yields. Single cropped DPL 90 produced $8.47 more income/acre than McNair 235, following Poco barley. However, double cropped cotton and barley produced $57.96 more/acre than single cropped cotton, followed by single cropped wheat.

    • Estimating Cotton Yields Using Small-Format Aerial Photography

      Parton, M. C.; Mulrean, E. N.; Department of Arid Lands Studies; Department of Plant Pathology (College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)
      In 1981, the University of Arizona's Department of Plant Pathology and Office of Arid Lands Studies (Arizona Remote Sensing Center) began a joint research project to map and estimate concomitant reductions in yield caused by Phymatotrichum root rot (PRR) using simulated orbital and airborne imagery. With support from the U.S. Department of Agriculture, Cooperative States Research Service and NASA-Ames Research Center, substantial progress has been made in improving estimates of yield. While work to date has been limited to cotton, future studies will include additional crops and other diseases.

      Two insecticide applications were made to cotton in late August and early September. Higher Bemisia tabaci populations were observed in the malathion treatment, as sampled by vacuum samples, and in the DyloxR and malathion treatments, as sampled by yellow sticky traps. Generally, the numbers of parasites collected were higher in untreated check plots than in the insecticide treated plots.

      Torok, Steven J.; Haden, Kimberly L.; Arizona State University; Oklahoma State University (College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)
      This study compared selected hedging strategies for Arizona upland cotton producers including a no- hedge, a planting hedge, and several technical hedging strategies for the time period 1974-82. Technical hedging strategies relied upon forecasting methods to signal the placing and lifting of hedges. Forecasting methods employed included moving averages, exponential smoothing and linear regression analysis. Hedging strategies were plotted in regions of preference relative to no-hedge and planting hedge strategies.
