Alternative Crops and Germplasm Selection

Replacement of imported produce with local products is an important objective of Hawaii growers and other advocates of sustainable agriculture. Effective competition with imported produce will require a combined effort to reduce costs and maximize quality in local commodities. One of the first steps farmers can take to ensure high yield and quality is selecting well-adapted and alternative crops. Variety selection and evaluations has been identified as a high priority need by Hawaii CES agents and growers. A primary focus of these evaluations is to optimize grower profits through enhanced quality and reduced costs of production.



Aquaponics (the integration of aquaculture and hydroponics) is an emerging technology that serves as a model of sustainable food production. In a recirculating aquaponic system (RAS), liquid effluent rich in plant nutrients derived from fish manure, decomposing organic matter and metabolic byproducts from protein catabolism in fish, fertilizes hydroponic beds providing essential elements for plant growth. Our research and outreach programs focus on identifying optimum germplasm and production strategies for cinder based aquaponic systems.

Chile Peppers

A hot pepper trial was conducted with CES agents Glenn Teves and Alton Arakaki in 2009. Texas A&M pepper program also supported the trial by providing germplasm and analyzing peppers for capsaicin content. Field days were conducted on both Oahu and Molokai in September and November of 2009. Labor costs and marketing implications of gentic variability in capsaicin were discussed. Reports are being developed for dissemination to agents and other ag. professionals. Additional trials designed to train agents in quality evaluation are scheduled for 2010-2011.

The overall goal of the Moringa working group at the University of Hawaii is to enhance the contribution of Moringa oleifera to food security and grower profitability in the Tropical and sub-Tropical U.S. states, territories and protectorates through germplasm evaluation, improved agronomy and market expansion. Current Moringa research at the University of Hawaii includes germplasm evaluation and investigations of the mycorrhizal dependency of two Moringa species. Investigations aimed at optimizing the agronomy of the crop for leaf, pod and oil production are pending.
