  • 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, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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.
  • Robotham, Michael; Smith, Chris; Valenzuela, Hector (University of Hawaii, 2004-01)
    Sampling for environmental pollutants that result from agricultural practices is described.
  • 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.
  • 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.
  • Hue, NV; Uchida, R; Ho, MC (University of Hawaii, 2004-07)
    Soil sampling procedure for samples to be submitted to a laboratory for fertility analysis are described, and the standard analyses performed are explained. A form for submitting samples to the UH-CTAHR Agricultural ...
  • 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.
  • Wong, Melvin (University of Hawaii, 2005-01)
    General recommendations on soil amendments to influence soil pH, nutrient availability, and drainage in various types of soils are given.
  • Wong, Melvin (University of Hawaii, 2005-01)
    Keys to identifying nutrient deficiencies based on whether they first occur on older leaves or newer leaves are given, and iron deficiency on four ornamental plants is shown.
  • Nelson, Scot C; Bushe, Brian C (University of Hawaii, 2006-07)
    Guidelines for collecting samples for submission to the UH-CTAHR Agricultural Diagnostic Service Center are outlined. Photos of examples of disease infection and pest infestation of many crops are included, and a worksheet ...
  • 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 ...
  • 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 ...
  • Sato, Dwight (University of Hawaii, 2007-03)
    Germination and seedling establishment are covered.
  • Hooks, Cerruti R2; Fereres, Alberto; Wang, Koon-Hui (University of Hawaii, 2007-06)
    The utility of plant barriers to reduce aphid movement in crops and the resulting transmission of plant viruses is discussed.
  • 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; 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.
  • 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.
