Mushrooms, Moringa and Chickens, Oh My! These topics and many others are covered in this, the Summer 2014 issue of HānaiʻAi, the sustainable agriculture newsletter of the College of Tropical Agriculture and Human Resources. Make sure to visit the "back pages" of the newsletter as well, which features Publications & Programs, upcoming Workshops, Conferences and Meetings, and the Organic Update. Stay up to date with our weekly SOAP activities via our twitter feed at: https://twitter.com/SOAPHawaii. As always, The mission of HānaiʻAi is to provide a venue for dissemination of science-based information to serve all of Hawaii's farming community in our quest for agricultural sustainability, and we would like to hear from you.

Feature Farmer

Paul & Charlie Reppun

Waianu Farm, Waiahole, Oʻahu



Area under production: approximately 10 acres

Years farming in Hawaiʻi: 40 years

Crops grown, products/services: Taro is our primary crop and other main crops are sweet corn, sweet potato, breadfruit, coffee and cacao. We produce poi and several value added products from the coffee and cacao. We produce honey and have begun producing greenhouse grown produce, particularly tomatoes. We also grow a wide range of tropical fruits mostly for home consumption.

Number of employees and/or family members involved: Both families are actively involved with farm operation. We don’t have additional paid employees outside the family, but we do have volunteer days.

Hot Tip from Waianu Farm

Learn the basics of engine and automobile mechanics; it’s more important to have mechanic friends than farmer friends.

Maui Master Gardener Program:

Attractors, Repellants, Trappers and Pollinators – Insectary Plants

Lorraine Brooks, Maui CES Extension Agent, UH-CTAHR

Mary Matsukawa and John Torrence, MG Class of 2014


The 2014 cohort of Maui Master Gardeners completed their gardens and class work in May. The class created four new gardens at the UH/Maui College of Tropical Agriculture and Human Resources (CTAHR) site. The idea behind this year’s gardens is to demonstrate how plants can attract pollinators, repel insects that damage crops and also trap insect pests away from crop product. Read here.

Small-scale Laying Hen Feeding Trial

Matthew H. Stevenson, UH-CTAHR HNFAS


A series of backyard chicken raising workshops held on Kauai and Maui from 2010 – 2011 revealed a need for more information on feeding strategies for small flocks in Hawaii. To that end, we designed a demonstration trial to test four simple feeding approaches many small-scale flock owners use for laying hens. Read here.

Determining fruit fly (Family Tephritidae) host status of moringa tree pods, Moringa oleifera Lam., in Hawaiʻi

Christine Lynch and Helen Spafford, CTAHR PEPS


There has been a growing interest on Oʻahu to find more ways to market and sell different edible parts of the moringa, since many growers already have moringa trees on their farms. This study has helped prove that moringa pods are not a suitable host for the four invasive fruit flies found in Hawaiʻi. Read here.

Mushroom Compost to battle against nematode pests on vegetable crops

Shelby Ching and Koon-Hui Wang, UH-CTAHR TPSS


Many farmers are looking for alternative methods to chemical approaches for managing nematodes in the soil. This project is exploring different approaches to use mushroom compost for the suppression of root-knot nematodes (Meloidogyne incognita) through: 1) direct incorporation of the mushroom substrate into the soil before crop planting, 2) drenching mushroom compost water extract into the root system after crop planting, and 3) amending mushroom compost into the growth media of transplant trays. Read here.

Cash Flow:

Determine how much cash you need to operate your business

By Steven Chiang

Director, UH Agribusiness Incubator Program


A cash flow projection enables you to anticipate how much cash is expected to flow in and out of your business. It is a forecast of your company’s cash income and expenses on a periodic basis (e.g. weekly or monthly). Use it to predict cash shortfalls, financing needs, and to plan for investments and expenditures. Read here.

Organic Update

Waimanalo Research Station holds sustainable agriculture open house: 

CTAHR showcases 20 years of sustainable and organic research and practice

2013 marked the 20th anniversary of the founding of CTAHR's organic extension and outreach at the Waimanalo research station by Dr Hector Valenzuela. The Sustainable and Organic Agriculture Program (SOAP) at the UH Mānoa College of Tropical Agriculture and Human Resouces (CTAHR) hosts an Organic Field Day at the college’s Waimanalo Research Station on Saturday, July 26, from 9:00 a.m. to 1:00 p.m. The field day includes variety trials of hot peppers and eggplant as well as educational displays on taro, ‘uala (sweet potato), papaya, and fertilizer types.

USDA to continue funding organic certification

USDA announced that approximately $13 million in Farm Bill funding is now available for organic certification cost-share assistance. The certification assistance is distributed through two programs within the Agricultural Marketing Service. Through the National Organic Certification Cost-Share Program, $11.5 million is available to all 50 states, the District of Columbia, and five U.S. Territories. Through the Agricultural Management Assistance Organic Certification Cost-Share Program, an additional $1.5 million is available to organic operations in 16 states including Hawaii.

For New Farmers


GoFarm Hawai`i graduates 2nd cohort

Congratulations to the graduates of GoFarm Hawai`i @ Windward's AgSchool2. Ten months of hard work and learning has resulted in the development of some fine farmers, some of which are starting to farm their own land in Waimanalo and Kamehameha School's land, and some of which are entering the AgIncubator plots at CTAHR's Waimanalo Agricultural Research Station to begin their careers as real farmers! Read here.
