  • Nakasone, H.Y.; Kamemoto, H. (Hawaii Agricultural Experiment Station, University of Hawaii, 1962-07)
    Efficiency in growth and flowering of the anthurium plant depends upon a number of factors, of which growing medium and sunlight level may be considered the two most important factors. This paper gives the results of testing ...
  • Nakamura, Martha; Sherman, G. Donald (Hawaii Agricultural Experiment Station, University of Hawaii, 1958-02)
    The Hawaiian Islands were formed from basaltic lavas, some of which have high concentrations of pyroxene and olivine. Since chromium is associated with the foregoing minerals, it is reasonable to assume that the element ...
  • Monteith, N.H.; Sherman, G. Donald (Hawaii Agricultural Experiment Station, University of Hawaii, 1963-06)
    Several current field experiments in the Hawaiian sugar industry have shown that liming has increased both yield of sugar and phosphorus uptake by the plant. This interest led to the initiation of this study, which had as ...
  • Bess, Henry A.; Haramoto, Frank H. (Hawaii Agricultural Experiment Station, University of Hawaii, 1961-06)
    The Oriental fruit fly, Dacus dorsalis Hendel, was first found in Hawaii in 1945 (van Zwaluwenburg, 1947). During the following year it increased to epidemic populations and caused serious damage to many crops throughout ...
  • Awada, Minoru; Suehisa, R.H. (Hawaii Agricultural Experiment Station, University of Hawaii, 1975-02)
    This publication reports on work to establish the petiole nitrogen level with greater precision than done in the previous work at Waimanalo and Puna. Oher variables besides petiole nitrogen which were found to affect fruit ...
  • Orr, Kathryn J.; Miller, Carey D. (Hawaii Agricultural Experiment Station, University of Hawaii, 1955-05)
    Quick-freezing of Hawaii fruits is a comparatively new process in the Islands, and much work is needed to determine the methods that will provide products of high quality. Mangos grow on all the Hawaiian Islands, but not ...
  • Wu, I-Pai; Gitlin, Harris M. (Hawaii Agricultural Experiment Station, University of Hawaii, 1974-06)
    This report presents a simple way of estimating friction drop along the lateral line, pressure distribution along the drip line, and variation of emitter discharge along the lateral. Design charts are presented for determining ...
  • Yamane, G.M.; Nakasone, H.Y. (Hawaii Agricultural Experiment Station, University of Hawaii, 1961-06)
    The low natural fruit set of acerola in Hawaii, attributed to absence of pollen transferring agents, indicated the feasibility of growth regulator application to induce fruit set. Among the several growth regulators tried ...
  • Rixon, A.J. (Hawaii Agricultural Experiment Station, University of Hawaii, 1966-06)
    Soils derived from volcanic parent material are of considerable agricultural importance in the humid tropics. Abundant sources of lime in the form of coral stone often occur in the vicinity of these acidic soils; thus, an ...
  • Awada, Minoru; Ikeda, Warren S. (Hawaii Agricultural Experiment Station, University of Hawaii, 1957-01)
    The experiment reported in this paper was conducted to observe the effects of water and nitrogen, differentially applied, on (1) leaf composition, (2) growth of the plants, (3) concentration of sugar in the fruits, (4) ...
  • Kawanishi, Clinton Y. (Hawaii Agricultural Experiment Station, University of Hawaii, 1975-04)
    The subject of this study, the drywood termite Cryptotermes brevis (Walker), is a kalotermitid of considerable economic importance. Relatively little is known about its life history and behavior. This species, like other ...
  • van't Woudt, Bessel D.; Uehara, Goro (Hawaii Agricultural Experiment Station, University of Hawaii, 1961-10)
    Bauxite is an aluminum-rich end product of soil weathering under certain conditions of favorable drainage in tropical regions. The ore is thus concentrated at the surface and its mining entails stripping the soil for some ...
  • Kamemoto, H.; Nakasone, H.Y. (Hawaii Agricultural Experiment Station, University of Hawaii, 1963-07)
    The culture of anthuriums, Anthurium andraeanum, in Hawaii has gradually evolved from a hobby status to an important cut-flower industry. With the realization of the need for a systematic evaluation of available varieties ...
  • Tanada, Y.; Holdaway, F.G. (Hawaii Agricultural Experiment Station, University of Hawaii, 1954-10)
    The present study concerns the feeding habits of the tomato bug, Cyrtopeltis (Engytatus) modestus (Distant), and the unusual feeding lesions produced on tomato plants. Existing information on the feeding habits and the ...
  • Nordfeldt, Sam; Henke, L.A.; Morita, K.; Matsumoto, H.; Takahashi, M.; Younge, O.R.; Willers, E.H.; Cross, R.F. (Hawaii Agricultural Experiment Station, University of Hawaii, 1952-07)
    Leguminous plants have long been considered important as livestock feeds in Hawaii. They decrease the need for costly oil cakes and protein rich concentrates in milk and meat production. Indigofera endecapliylla Jacq. ...
  • Clements, Harry F. (Hawaii Agricultural Experiment Station, University of Hawaii, 1975-12)
    Flowering of sugarcane is a mixed blessing for the grower: on the one hand, flowering is essential for the improvement by commercial cane breeding; on the other hand, it can cause very substantial losses of yield in ...
  • Willett, E.L.; Henke, L.A.; Work, S.H.; Maruyama, C.; Ross, Winifred (Hawaii Agricultural Experiment Station, University of Hawaii, 1948-02)
    Garbage is the main feed for swine in the Territory of Hawaii because of the high cost of other concentrates commonly fed to hogs. An extensive study has therefore been made of the value of garbage as a feed for swine. ...
  • Akamine, Ernest K. (Hawaii Agricultural Experiment Station, University of Hawaii, 1944-10)
    Poor germination resulting from dormancy of seeds has been a major problem in use of many desirable species of Hawaiian range grasses. Dormancy in seeds is the result of one or more of the following conditions: (1) presence ...
  • Wu, I-Pai; Howell, Terry A.; Hiler, Edward A. (Hawaii Agricultural Experiment Station, University of Hawaii, 1979-12)
    The research results reported in this publication are derived from studies on hydraulics of drip irrigation from 1973 to 1978.
  • Uehara, Goro; Sherman, G. Donald (Hawaii Agricultural Experiment Station, University of Hawaii, 1956-12)
    A study was made of the mineralogical constitution of the soils of the red and black complex of the Hawaiian Islands. The application of differential thermal analysis established kaolin as the dominant mineral in the red ...
