  • Sato, Dwight (University of Hawaii, 2007-03)
    Germination and seedling establishment are covered.
  • Miyasaka, Susan C; Hollyer, James R; Cox, Linda J (University of Hawaii, 2001-07)
    A field experiment evaluated effects of organic inputs on crop yield and quality and incidence of pocket rot, which commonly diminishes non-flooded taro yields by a quarter to a third. Considering the costs of organic ...
  • Hooks, Cerruti R2; Chandara, Khamphout; Fallon, Declan; Wang, Koon-Hui; Manandhar, Roshan (University of Hawaii, 2007-10)
    Impacts of growing Crotalaria juncia on factors such as plant-parasitic and beneficial nematodes, nematode-trapping fungi, and cucumber yields were studied.
  • Fares, A; Abbas, F (University of Hawaii, 2009-05)
    Common sources of nutrients with solubility suitable for application in micro-irrigation systems are reviewed.
  • Hue, NV; Silva, JA; Uehara, G; Hamasaki, RT; Uchida, R; Bunn, P (University of Hawaii, 1998-06)
    As sugarcane became replaced by diversified cropping, crop sensitivity to high manganese levels in certain soils of central Oahu and the North Shore became a concern. The publication discusses the potential for Mn toxicity, ...
  • Miyasaka, SC; Habte, M; Friday, JB; Johnson, EV (University of Hawaii, 2003-07)
    General use of mycorrhizal fungi in cropping is reviewed. Instructions on producing inoculum from a commercial starter-culture are given.
  • Brewbaker, James L (University of Hawaii, 2009-11)
    This publication reviews research at the University of Hawaii’s College of Tropical Agriculture and Human Resources to evaluate corn hybrids for the silage and bioethanol industries in Hawaii. Maximizing yields is shown ...
  • Deenik, Jonathan (University of Hawaii, 2006-07)
    Soil microorganisms convert nitrogen in soil organic matter into inorganic forms that plants can take up; the process is called N mineralization. The N cycle and factors affecting mineralization are reviewed. Mineralization ...
  • Miyasaka, Susan C; Hamasaki, Randall T; de la Pena, Ramon S (University of Hawaii, 2002-07)
    The publication provides a key to taro nutrient disorders, identifies the leaf to sample for nutrient analysis, gives nutrient concentrations associated with deficiency, sufficiency, and toxicity, and illustrates symptoms ...
  • Joy, Robert J; Evans, Dale O (University of Hawaii, 2008-09)
    Obtaining seeds of cover crops, green manure crops, and improved forage species is discussed, some sources in Hawaii are identified, and consideration is given to weed risk assessment regarding use of the various plants ...
  • Anonymous (University of Hawaii, 2007-09)
    Herbicide, insecticide, and fungicide products registered for use on flooded or non-flooded taro crops in Hawaii in 2007 are discussed.
  • Deenik, J; Hamasaki, R; Shimabuku, R; Nakamoto, S; Uchida, R (University of Hawaii, 2006-10)
    Repeated long-term applications of blended fertilizers (containing N, P, and K) have resulted in soil P levels that are in excess of optimal in many situations. Field experiments on five farms (on three soil series) compared ...
  • Deenik, J; Hamasaki, R; Shimabuku, R; Uchida, R (University of Hawaii, 2007-09)
    Field experiments at two sites determined that for Romaine lettuce on the soils tested, no further P fertilizer application is need if extractable P is above 650 ppm.
  • Hepperly, Paul; Zee, Francis; Kai, Russell; Arakawa, Claire; Meisner, Mark; Kratky, Bernard; Hamamoto, Kert; Sato, Dwight (University of Hawaii, 2004-06)
    A bacterial wilt is the factor most limiting yields of culinary ginger in Hawaii. A system developed to produce ginger in an artificial medium in greenhouse culture is described.
  • Wong, Melvin (University of Hawaii, 2005-01)
    Early salinity damage to plants is often not detected. The symptoms of salinity injury include dark bluish-green foliage, smaller leaves, shorter internodes, reduced growth, and chlorotic lower leaves at later growth stages.
  • Ogoshi, RM; Tsuji, GY; Uehara, G; Kefford, NP (University of Hawaii, 1998-10)
    The study showed that an agronomic model and economic analysis are useful tools for agricultural decision-making in Hawaii. Crop models shortened the time needed to test and determine suitable management schemes to produce ...
  • Ikawa, Ike; Hue, Nguyen; Yost, Russell (University of Hawaii, 2010)
    This poster describes and provides color photos of ten different soil orders in Hawaii.
  • Deenik, J; McClellan, AT (University of Hawaii, 2007-09)
    Ten major soil orders found in Hawaii are described, and maps show their distribution on the six main Hawaiian islands.
  • Kawabata, AF; Nishijima, WT (University of Hawaii, 2004-06)
    Optimal conditions for temperature, light, fertilizer, and water affecting production, shipping, and postproduction of 7 important foliage plants produced for export in Hawaii are given in a table.
  • Robotham, Michael; Smith, Chris; Valenzuela, Hector (University of Hawaii, 2004-01)
    Sampling for environmental pollutants that result from agricultural practices is described.
