    • Integrating Variable Rate Technologies for Soil-applied Herbicides in Arizona Vegetable Production

      Nolte, Kurt; Siemens, Mark C.; Andrade-Sanchez, Pedro; Plant Sciences, School of (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2011-02)
      Precision herbicide application is an effective tool for placing soil incorporated herbicides which have a tendency for soil adherence. And while field implementation depends on previous knowledge of soil textural variability (soil test and texture evaluations), site-specific technologies show promise for Arizona vegetable producers in non-uniform soils. Regardless of the method used for textural characterization, growers should keep in mind that textural differences do not change in the short/medium term, so the costs associated with defining texture-based management zones can be spread over many years.

    • Irrigation Interval Effect on Yield and Quality of Forage Sorghum at Maricopa, AZ, 2015

      Ottman, Michael J; Diaz, Duarte E; Sheedy, Michael D; Ward, Richard W (College of Agriculture, University of Arizona (Tucson, AZ), 2017-02)
      Sorghum has the advantage compared to corn in that it uses less water and fertilizer, but feeding quality of sorghum is usually less than corn. The purpose of this research is to compare the yield and quality of sorghum grown with differing frequency of irrigation water application. Forage sorghum was grown at the University of Arizona Maricopa Agricultural Center with irrigation intervals of 1, 2, and 3-weeks corresponding to 76, 44, and 37 inches of applied water. Forage yield at 72% moisture was 20.6, 18.8, and 16.5 tons/acre for the 1-, 2-, and 3-week irrigation intervals, respectively. Forage quality in terms of milk per ton of forage was not affected by irrigation interval, but some differences were measured in certain components of feed quality. Forage yield profit was maximized at the 2-week irrigation interval due since the increased water cost of the 1-week interval was not compensated by the yield increase at this irrigation frequency.

    • Late Season N Application Method Effect on Grain Protein, 2016

      Ottman, Michael J; Sheedy, Michael D; Ward, Richard W (College of Agriculture, University of Arizona (Tucson, AZ), 2016-11)
      Nitrogen fertilizer is normally applied later in the season around flowering time to boost grain protein content. The purpose of this study is to determine if the grain protein boost provided by late N application is affected by method of application. A trial testing late season N application methods was conducted at the Maricopa Ag Center in the 2016 growing season. The crop was grown 211 lb N/acre in split applications until flowering when 35 lb N/acre was applied as UAN32 in the irrigation water (fertigation), as low biuret urea in a foliar application, or as urea granules compared to no N application at all at flowering. In this study, we were not able to detect a difference in grain protein or any other variable measured due to the late N application method. We did measure a 0.4% increase in grain protein regardless of late season N application method compared to the control with no late N applied.
