Corn Production in the Tropics: the Hawaii Experience

Brewbaker, James L (University of Hawaii, 2003)
The Economic Feasibility of Growing Taro in Rotation with Field Corn for Dairy Silage on the Island of Kauai

Thomassin, Paul; Leung, PingSun; Wang, Jaw-Kai (University of Hawaii, 1985-11)

This study was conducted to determine the economic feasibility of growing taro in rotation with field corn for dairy silage during the wet months of the year on the island of Kauai, Hawaii. It was found that it would be ...
Growth Response Curves--The "Law of Diminishing Returns"

Fox, Robert L (University of Hawaii, 1971)

A graphing of corn yield response to added phosphorus on a P-deficient soil (Tropeptic Eutrostox) illustrates Mitscherlich's equation of diminishing returns.
Insects Injurious to Corn

Fullaway, David T (Hawaii Agricultural Experiment Station, 1912-07-11)

This bulletin discusses the following insects attacking corn: wireworms, cutworms, army worms, plant lice, leaf lhoppers, defoliating caterpillars, earworms, and grain feeders.
Maximizing Yields of Corn for Silage and Bioethanol in Hawaii by Increasing Planting Density

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 ...
Nitrogen Application Promotes Root Proliferation and Vegetative Growth of Corn

Asghar, M; Kanehiro, Y (University of Hawaii, 1977)

The effect of urea nitrogen fertilizer on corn root and shoot growth is illustrated.
Sweet Corn

Brewbaker, James L (University of Hawaii, 2008-08)

Hawai‘i’s short days and plethora of diseases corn doesn’t encounter on the U.S. mainland limit productivity of hybrids developed for temperate conditions. “Supersweet” cultivars developed in Hawai‘i are preferred, and ...
Symptoms of Plant Malnutrition--Multiple Deficiencies and "The Law of the Minimum"

Fox, Robert L (University of Hawaii, 1971)

The manner in which phosphorus inputs affect expression of zinc deficiency on corn growing in a soil (a Hydrandept) with high phosphorus immobilization ("fixation") capacity is illustrated with photographs.
Symptoms of Plant Malnutrition--Visual Symptoms and Incipient Malnutrition

Fox, Robert L (University of Hawaii, 1972)

Corn was grown across a gradient created with increasing doses of urea fertilizer. Comparison of a photograph of the corn row with a plot of the yield of fresh husk sweet corn revealed that disappearance of visual N ...
