(University of Hawaii, 1999-07)General recommendations for fertilizing turfgrasses are given in pounds of nitrogen per 1000 square feet, but fertilizers contain different amounts of N, and lawns vary in area. A method for measuring the square footage ...
-
(University of Hawaii, 2000)The goal of a nutrient management plan is to ensure the availability of adequate nutrients for crop production with minimal nutrient loss in runoff or leaching from the root zone. Such a plan should include an evaluation ...
-
(University of Hawaii, 1973)Controls to reduce available nitrogen and soil water in a maturing sugarcane crop can have a positive influence on the yield and quality of the cane.
-
(University of Hawaii, 1958-07)Thirteen variations in amounts and frequencies of applications of nitrogen and potassium to coffee plants were evaluated for effects on yield and tissue nutrient content. Results suggested that only two N applications ...
-
(University of Hawaii, 1980)In a field experiment with banana, fertilizer variables were applied systematically in strips across the blocks so that N increased gradually from none to large quantities in one direction, while K increased gradually ...
-
(University of Hawaii, 1977)The effect of urea nitrogen fertilizer on corn root and shoot growth is illustrated.
-
(University of Hawaii, 1990-01)The response of Chinese Taro (Colocasia esculenta (L.) Schott variety 'Bun Long') to 12 treatment combinations of nitrogen (N) and potassium (K) was determined on a crop grown for 9 months. Nitrogen had the greatest effect ...
