    • 2016 Cotton Variety Testing Results – Report

      Norton, Randy; Ayman, Mostafa (College of Agriculture, University of Arizona (Tucson, AZ), 2017-02)
      Variety selection is one of the most important decisions a grower will make contributing to the success of a cotton crop. It is critical, that a grower have as much information as possible in order to make an informed decision regarding variety selection. In an effort to help supply reliable variety performance information, the University of Arizona conducts a statewide Upland cotton variety testing program. This program consists of a few different types of trials. The first is a small plot evaluation of commercially available varieties along with experimental varieties, and is conducted in 3 locations across Arizona including; Yuma, Maricopa, and Safford. This testing program is called the University of Arizona Upland Cotton Advanced Strains Testing Program.
    • A Turfgrass Maintenance Guide for Residential and Commercial Lawns in the Low Elevation Arizona Desert

      Umeda, Kai; Kopec, David (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2020-04)
      Homeowners commonly desire to have a functional lawn for children to play upon and for their pets. Lawns also contribute to the aesthetics and value of residential or commercial properties as well as offering many environmental advantages. The right-sized lawn in the right place with an efficient irrigation system can provide all of these benefits.
    • Aerobic and Anaerobic Grape Pomace Composting: The Pros and Cons

      Mpanga, Isaac K. (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2022-01)
      In Arizona, wine production increased from 65,413 gallons (2007) to 297,145 gallons 2017) (Murphree, 2018), with an estimated 354% increase in grape pomace production within the same period. The grape pomace is a by-product of the wineries, which is obtained after crashing the grape fruits, fermenting and pressing the juice.

    • Agricultural Use of Recycled Water for Crop Production in Arizona

      Cusimano, Jeremy; McLain, Jean E.; Eden, Susanna; Rock, Channah M. (College of Agriculture, University of Arizona (Tucson, AZ), 2015-06)
      Agriculture is by far the largest water-demanding sector in Arizona, accounting for 70% of water demand (ADWR, 2009). Arizona’s agriculture industry is extremely diversified, producing many crops that can legally be irrigated with recycled water, including cotton, alfalfa, wheat, citrus, and vegetables. Throughout the State, farming communities are taking advantage of increasing supplies of recycled water.
    • Alfalfa Aphid Complex

      Knowles, Tim C.; Entomology (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 1998-08)
      The alfalfa aphid discussed in this publication includes blue alfalfa aphid, pea aphid, and the spotted alfalfa aphid. This publication discusses the biology of these alfalfa aphids, the damages they cause, the resistant varieties and biological control, and their monitoring and treatments.
    • Alfalfa Caterpillar/Butterfly

      Knowles, Tim C.; Entomology (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 1998-08)
      The first sign of a potential alfalfa caterpillar (Colias eurytheme) outbreak is the influx of large numbers of yellow or white butterflies in late spring or early summer. This publication discusses the biology of the alfalfa caterpillar, the damage it causes, the biological and cultural controls, and the treatments for it.

    • Alfalfa Weed Control in the Low Deserts of Arizona

      Ottman, Michael; Tickes, Barry; Plant Sciences, School of (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2008-04)
      The most effective weed control practice in alfalfa is maintaining a healthy crop and dense stand. Cultural practices that promote a vigorous stand can reduce the need for chemical weed control. Cultural practices that promote a healthy stand reduce the need for chemical weed control, but herbicides are sometimes necessary even in well-managed alfalfa.
    • Alternaria Leaf Spot of Cotton

      Hu, Jiahuai; Norton, Randy (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2020-09)
      Alternaria leaf spot of cotton is also known as Alternaria leaf blight. The disease was first identified in cotton in the US in 1918 and is now distributed worldwide. Alternaria leaf spot has been considered a minor disease in the cotton growing areas of Arizona. The disease is frequently associated with senescing tissue of cotton under physiological stress (heavy boll load) or nutritional stress (potassium deficiency) late in the growing season. On rare occasion it can also affect seedlings. In recent years, several disease outbreaks that led to severe defoliation in late-season cotton were reported from Graham County. The disease can severely affect susceptible Pima cotton varieties and also attack upland cotton varieties. Susceptible varieties have had nearly 100% of leaves infected in years when weather conditions are conducive for disease infection and development. The impact on yield in Arizona was estimated to be 10% to 15% in highly susceptible cotton varieties.
    • Ancient Rediscovering Food: Grain Amaranth

      Moya Cortazar, Sheila; Ottman, Michael; McDaniels, Amanda; Aragon Cereceres, Andrea; Hongu, Nobuko (College of Agriculture, University of Arizona (Tucson, AZ), 2017-04)
      Grain amaranth was a dietary staple for Central American Indians before Columbus arrived in the New World.1 Today, in Mexico, amaranth is popped like popcorn and mixed with sugar or honey to make a popular sweet treat, called “Alegría” which is the Spanish word for joy (Figure 1). Amaranth is a nutritious grain, similar to chia seeds2 and quinoa, providing high amount of plant protein, fiber, iron, and calcium. This article can help you learn more about amaranth, and show you how to incorporate them into your balanced diet.
    • Annual Bluegrass (Poa annua) Control in Non-overseeded Bermudagrass and Winter Overseeded Turfgrasses in Low Desert Arizona

      Umeda, Kai; Kopec, David; Nair, Shakunthala (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2021-05)
      Annual bluegrass (Poa annua) is a cosmopolitan weed in most turfgrasses. In Arizona, the vast majority of the annual bluegrass is a true winter annual weed (Poa annua var. annua L. Timm.) that germinates in the fall, grows throughout the winter season, flowers profusely in the spring, and then dies as the summer temperatures rise. The weed seed remains in the soil all summer and then germinates during the next fall. The annual form var. annua is more upright in growth habit and prolifically produces stemmy seedheads that often grow in a circular pattern around the leaves, especially when the turf is mowed regularly.
