  • Nondormant Alfalfa Varieties for Arizona 2017

    Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 2017-09)
    Alfalfa varieties differ in fall dormancy, defined as growth during the fall. Nondormant alfalfa varieties are usually planted in mild winter areas for their ability to grow in the fall. However, fall growth of nondormant alfalfa may be undesirable in areas subject to repeated frosts or freezes. Nondormant, very nondormant, and extremely nondormant alfalfa varieties (fall dormancy class 8, 9, and 10) are adapted to elevations below 4000 feet in Arizona. Other dormancy classes not included in this publication are moderately nondormant varieties (fall dormancy class 7) which may be grown from 3000 to 5000 feet, and semi-dormant and dormant varieties (fall dormancy 6 and below) which are adapted to colder winter areas above 4000 feet.
  • Eating for Two – A Healthy Pregnancy Starts with a Healthy Diet

    Wyatt, Melissa; da Silva, Vanessa (College of Agriculture, University of Arizona (Tucson, AZ), 2017-10)
    The saying “you are what you eat” takes on a new meaning when a woman learns she is expecting a baby. For the next several months, her growing baby’s health is directly dependent upon what she eats, and what she chooses to avoid. What is more, a woman’s diet during pregnancy has been shown to affect her child’s health long after she is no longer eating for two.

  • Osteoporosis

    Misner, Scottie; Farrell, Vanessa A. (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)
    Osteoporosis means “porous bones.” It is a condition where the skeleton becomes fragile and results in broken bones under normal use. Osteoporosis is a “silent” condition that happens slowly over years. The rate of bone loss (“resorption”) exceeds the rate of new bone formation (“acretion”). Many times neither a person nor a doctor is aware of weakened bones until one breaks unexpectedly. Originally published: 2000
  • Human Disease Causing Viruses Vectored by Mosquitoes

    Gouge, Dawn H.; Hagler, James R.; Nair, Shaku; Walker, Kathleen; Li, Shujuan; Bibbs, Christopher S.; Sumner, Chris; Smith, Kirk A. (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)
    There are a number of disease-causing viruses transmitted to people primarily through the bite of infected mosquitoes. Female mosquitoes take blood meals to produce eggs. A mosquito that bites an infected animal may pick up a virus within the blood meal. If the mosquito is the appropriate species, and conditions inside the insect and the surrounding environment are supportive, the virus reproduces within the mosquito. Later, the mosquito may pass the virus on to other animals (including humans) as they feed again.

  • Planting Pole Cuttings in Riparian Ecosystems

    Schalau, Jeff (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)
    Riparian ecosystems are found in the transition between aquatic and adjacent terrestrial ecosystems where unique vegetative communities can occur due to free water at or near the soil surface. A healthy, functional riparian plant community provides a rich environment for insects, mollusks, amphibians, reptiles, fishes, birds, and animals. In Arizona, many naturally occurring riparian ecosystems have been impacted, altered or removed by natural processes and land management activities. This publication provides information to assist residents, landowners, and agency personnel in successfully establishing pole plantings in riparian ecosystems of Arizona.

  • Rangeland Management Before, During and After Drought

    Howery, Larry D.; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2016-12)
    Rangeland and livestock management in the southwestern U.S. presents many formidable challenges. Environmental regulations, cattle prices, and drought are just a few factors that contribute to the management challenges of the range-livestock industry. Among them, drought may be the least controllable or predictable variable. This publication discusses how to prepare for drought in southwestern U.S. Topics include principles of drought and range-livestock management, management before drought, management during drought and management after drought.

  • Non-Native Invasive Plants of Arizona

    Howery, Larry D.; Northam, Ed; Meyer, Walt; Arnold, Jennifer; Carrillo, Emilio; Egen, Kristen; Hershdorfer, Mary (College of Agriculture, University of Arizona (Tucson, AZ), 2016-12)
    The noxious weed problem in the western United States has been described as, a biological forest fire racing beyond control because no one wants to be fire boss. Indeed, when small weed infestations are left unchecked, they can grow exponentially and spread across the land much like a slow-moving biological wildfire. However, land consumed by fire usually recovers and is often more productive than before the fire occurred. On the other hand, land consumed by noxious weeds may be irreversibly changed and never again reach its full biological potential. Reviewed 12/2016, First Edition Published 2001
  • How Do Domestic Herbivores Select Nutritious Diets on Rangelands?

    Howery, Larry D.; Provenza, Fred. D.; Ruyle, George B.; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2016-12)
    Animal learning has been shown to play a major role in the development of diet selection by domestic herbivores. Dr. Frederick Provenza and his associates at Utah State University have conducted a series of studies over the past 30 years to learn how physiological and behavioral mechanisms govern diet selection. In this paper, we synthesize several key diet selection concepts presented in 4 articles (i.e., Provenza et al. 1992; Provenza 1995, 1996, 1997). Reviewed 12/2014; originally published 05/1998.

  • Growing Grain Sorghum in Arizona

    Ottman, Michael J; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2016-10)
    Production practices for grain sorghum are discussed including hybrid selection, planting date, seeding rate, row configuration, irrigation, fertilization, pest control, and harvesting. Grain sorghum (milo) is a warm season, annual grain crop. It is more resistant to salt, drought, and heat stress than most other crops. Nevertheless, highest yields are obtained when stresses are minimized. Revised 10/2016. Originally published 06/2009.
  • Principles of Obtaining and Interpreting Utilization Data on Rangelands

    Ruyle, George B.; Smith, Lamar; Maynard, Jim; Barker, Steve; Stewart, Dave; Meyer, Walt; Couloudon, Bill; Williams, Stephen; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2016-10)
    A primary expression of stocking levels on rangeland vegetation is utilization defined as the proportion or degree of current years forage production that is consumed or destroyed by animals (including insects). Utilization may refer either to a single plant species, a group of species, or the vegetation as a whole. Utilization is an important factor in influencing changes in the soil, water, animal, and vegetation resources. The impact of a specific intensity of use on a plant species is highly variable depending on past and present use, period of use, duration of use, inter-specific competition, weather, availability of soil moisture for regrowth, and how these factors interact. Utilization data can be used as a guideline for moving livestock within an allotment with due consideration to season, weather conditions and the availability of forage and water in pastures scheduled for use during the same grazing season. In combination with actual use and climatic data, utilization measurements on key areas and utilization pattern mapping are useful for estimating proper stocking levels under current management. Utilization studies are helpful in identifying key and problem areas, and in identifying range improvements needed to improve livestock distribution. Reviewed 10/2016. Originally published 5/2007.
