Cover crops are the backbone of sustainable cropping systems: as they can prevent soil erosion, reduce nutrient leaching, add organic matter, improve soil health, fix nitrogen, suppress weeds, and reduce insect pests and diseases. In addition to these well-established benefits of cover cropping, leguminous cover crops can contribute significant amo...
Conference Paper
Utilizing locally available materials to create potting mix is vital for sustainable production of ornamental crops. Volcanic cinder is the most commonly used substrate in Hawaii because it is inexpensive, inert and highly porous, and thus provides good drainage for plants. Experiment was conducted to characterize the physical and chemical properti...

Tomatoes are an important economical crop for many small and large scale producers in Hawaii. Tomato yellow leaf curl, caused by Tomato yellow leaf curl virus (TYLCV), is a devastating disease of tomato worldwide and was first detected and identified in commercial tomato plantings around Oahu and Maui in 2009 (Melzer, et al, 2009). It has since bee...

Experimental trials were conducted at Windward Community College's (WCC) Freshwater Aq-uaculture and Aquaponics Research Facility on O'ahu Island. Trials were conducted over the course of several growing seasons to evaluate the effectiveness of aerated vermicompost tea in: 1) alleviating nutrient deficiencies (specifically inter-veinal chlorosis) i...

Extension agents brought forth concerns that a strange phenomenon was affecting multiple crop types in central Oahu. A multi-disciplinary team of specialists at the College of Tropical Agriculture and Human Resources (CTAHR) studied the incident called "Yellowing Problem" and ruled out disease and pesticide damage as the causal agent, leaving soil...

Reducing grower reliance on off-island inputs to promote plant nutrition has been identified by industry as a high priority in efforts to improve agricultural sustainability in Hawaii. A variety of knowledge gaps exist that prevent producers from using more locally produced amendments in their fertility program. This presentation will focus on rece...

Greenhouse experiments were conducted to evaluate the effects of different concentrations of vermicompost water extracts (teas) and seed soaking duration on germination of tomato (Solanum lycopersicum) and lettuce (Lactuca sativa) seeds. In the first experiment, tomato and lettuce seeds were soaked in vermicompost teas prepared from chicken manure-...

This study investigated the links between variability in compost quality, the biochemical characteristics of their extracts (compost tea) and plant growth indicator through a series of experiments. Five different commercially produced composts were selected for quality evaluation. They were: (i) chicken manure-based thermophilic compost (ii) green...
Conference Paper
Full-text available
This study investigated the effect of vermicompost tea on the germination of tomato and lettuce seeds. Greenhouse experiments were conducted twice during September to December, 2010. Aerated vermicompost tea was prepared by extracting commercially produced chicken manure-based vermicompost in water at 1:10 dilution rate (vermicompost to water ratio...

Previous work has demonstrated the potential of compost tea to enhance plant growth and nutritional status.One factor thought to contribute to variability in the efficacy of compost tea is the amount of compost per unit volume of water. To address these gaps in our understanding, two greenhouse trials and two field trials were conducted to investig...
Conference Paper
Two greenhouse trials and two field trials were conducted to investigate the effects of vermicompost tea (aqueous extract) on growth, tissue N and phytonutrient content of pak choi (Brassica rapa chinensis), and on soil biological properties. In the greenhouse experiments, plants were fertilized with chicken manure-based thermophilic compost. In th...

This study investigated the effects of vermicompost tea (aqueous extract) on yield and chemical quality of pak choi (Brassica rapa cv Bonsai, Chinensis group) grown in three media (two soils and a peat-perlite medium) under two fertilizer regimes (compost and synthetic fertilizer). The impacts of tea application on the chemical and biological prope...

Tea Time for the Garden Water based extracts of compost (compost tea) have a relatively long history in agriculture. This is not sur-prising since they are simple to make by soaking compost in water and agitating by stirring, aeration or other methods. Scientific investigations of claims of the benefits of compost tea are much more recent. Study re...
Conference Paper
Full-text available
Application of aqueous extract of vermicompost has been shown to improve plant health, yield and nutritive quality. Few studies have been conducted to determine the effect of vermicompost extract on soil biological properties. The objective of this study was to evaluate the independent effects and interaction between vermicompost extract and soil t...
Conference Paper
Full-text available
There is growing evidence that compost extract can benefit plant health and yield but a consistency of the effect is a concern. Compost quality plays a major role in extract quality; however, little work has been done to evaluate the effect of compost sources on compost extract quality and subsequent plant response. The objective of this study was...

BACKGROUND: Multiple studies have been reported on the effect of compost tea on suppression of certain plant diseases. However, relatively little work has been done to investigate the effect of vermicompost tea on yield and nutritional quality of vegetable crops. In this study, experiments were conducted to determine the effect of extraction method...

Multiple studies have reported on the effect of compost tea on suppression of certain plant diseases. However, relatively little work has been done to investigate the effect of compost teas on yield and nutritional quality of vegetable crops and even fewer studies have addressed the relationship between extraction methods, chemical and biological c...

A major threat to Hawaii's ecosystem is the spread of invasive plant species. One such species is Miconia calvescens. Given that this plant was originally introduced to Hawaii by the horticulture industry and has negative effects on agricultural productivity, it is logical to find the farm households' preference for the control of Miconia. Using Co...
