Providing science-based information to serve Hawaii's Farming Community

Hānaiʻ Ai

The Food Provider

September | October | November 2009  

Welcome to the Summer 2010 issue of HānaiʻAi, the sustainable agriculture newsletter of the College of Tropical Agriculture and Human Resources. 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.

We hope you find this issue of HānaiʻAi useful, and welcome your input.

 

Feature Farmer

Wooten ʻOhana

Kauaʻi Kunana Dairy, Kilauea, Kauaʻi

 

 

Area under production:

 1½ acres in crops, 13 acres livestock including dairy goats and laying hens.

 

Years farming in Hawai'i:

Since 1979.

 

Crops grown:

All crops are Certified Organic by HOFA: avocado, bananas, papayas, mango, citrus, lychee, soursop, salad crops, tomatoes, peppers, eggplant, cucumbers, beans, spinach, green onions, herbs, all cabbage types, broccoli, cauliflower, turnips, radishes, beets, chards, kales, arrugula

 

Fertility management:

We make 75% of our own fertilizer by composting our goat and chicken manure. Manure management is a big part of our operation. We do inter-planting and crop rotation as well as green manure crops.

 

Pest Management:

We time our plantings, interplant with trap crops, plant pest resistant varieties, and use mulch and traps.

 

What Sustainability Means to You:

Sustainability means being creative and innovative when challenges occur and using low-impact methods whenever possible.

 

HOT TIPS from Kula Country Farms

Integrating livestock into a sustainable farming system is something that every operation should consider. The benefits of keeping animals as part of a balanced farming system are many, even though they do require a lot of love and attention.

Cover Your Asset: Choosing appropriate cover crops for your Production System

Ted Radovich,

University of Hawai'i at Manoa, CTAHR

 

Cover crops are a time-tested strategy to improve the ecological function of tropical farming systems. There are multiple species that may be used. The species that is most ideal for any given situation will depend on the interaction of several factors, including inherent characteristics of the crop, the environment it's grown in and the primary objective(s) for using it. This article briefly discusses critical thinking involved in selecting and managing cover crops. The article also highlights Hawaii-based information that is available to help you in decision-making when selecting and managing your cover crops.

Price Maker or Price Taker? How to Differentiate your Products

 

Making a profit starts with a consumer who is willing to buy a product. Farmers who sell in commodity markets where one farmer’s product is the same as the another’s are faced with fierce competition. In order to escape this situation, many farmers try to convince consumers that their products are different from those of other farmers. The value of a product’s characteristics to a consumer is difficult to determine and agricultural producers must try to determine these values if they want to be profitable.

Avocado in Kona

Ty McDonalde

University of Hawai'i at Manoa, CTAHR

 

A few of the key agronomic variables for growing avocado are outlined, which indicate why the Kona district on the Big Island has traditionally been the principal avocado growing area in the state. Around 30 years ago the industry decided to produce and promote Sharwil avocados to reclaim the local market and to develop an export market. Unfortunately, in 1992, this effort was derailed when Hawaii producers were no longer allowed to export and the industry continued to lose market share to imported Hass avocados. Recently, efforts to remove this export restriction appear to be gaining ground.

Fruit quality of 'Sharwil' Avocado grown at three locations in South Kona

Nancy Chen, Marisa Wall, Robert Paull, and Peter Follett

University of Hawai'i at Manoa, CTAHR

 

CTAHR and USDA/ARS researchers recently completed a project that investigated the changes in fruit dry matter content, oil content and sensory quality throughout the harvest season for ‘Sharwil’ avocados grown at three orchard elevations during the 2007 and 2008 seasons. Fruit quality was similar in both seasons, regardless of orchard elevation. Late season fruit had a higher dry matter and oil content, were smaller in size, and had a shorter shelf life than early and midseason fruit. Fruit flavor and texture did not change throughout the season.

Sustainable Seed Production and Cover Crops

Cindy Goldstein and John McHugh

Pioneer Hi-Bred International, Inc.

 

Sustainable agriculture is integrated into Pioneer Hi-Bred International’s agronomy programs and guide the direction of their plant breeding programs to develop hybrids and varieties that help reduce agriculture’s environmental footprint. They conducted cover crop research at their Waialua Parent Seed station on Oahu with Crop Care Hawaii, LLC to identify agronomic benefits of cover crops by establishing on-farm demonstration plantings and then promote the continued adoption of the practice. Cover crops tested in these studies included sunn hemp (Crotalaria juncea), buckwheat, winter wheat, oats, barley, sudex, lana vetch, and mung beans. Sunn hemp has proven to be very effective as a cover crop for weed suppression and soil erosion control, although the production of an ample supply of sunn hemp seed has been a challenge.

Dry Litter Systems for Small-Scale Piggery Operations

Glen K. Fukumoto

University of Hawai'i at Manoa, CTAHR

 

A modified dry litter system for piggeries has been developed at CTAHR that promotes the collection and processing of nutrients using a managed composting system and eliminates the use of water for pen clean-up, which will reduce polluted run off. Two producers in Tinian, one in American Samoa, two on the island of Hawaii and one on Oahu are using the modified dry litter piggery system. The USDA NRCS has program funds in the Environmental Quality Incentive Program (EQIP) that can now be used to construct and implement the modified dry litter system.

Opportunities for the Application of Arbuscular Mycorrhizal Fungal Technology in Hawaii

Mitiku Habte

University of Hawai'i at Manoa, CTAHR

 

Over 90% of the plants in the tropics have arbuscular mycorrhizal (AM) fungi in their roots that enhance the uptake of diffusion-limited nutrients such as P, Cu, K, Zn and Fe. Soil samples from Kaua'i, Big Island, and O'ahu suggest that not enough AM fungi exist for rapid and effective mycorrhiza development and therefore, AM fungi must be applied to the soils as inocula. At present, AM fungal inocula is applied during nursery production of seedlings, while the interest to integrate the AM fungal technology in protocols for production of micropropagated plants is growing.

Improving Marigold cover cropping for Nematode Management

Koon-Hui Wang

University of Hawai'i at Manoa, CTAHR

 

Home gardeners often want to know organic approaches for controlling nematodes. One approach is to grow a ground cover, such as marigold (Tagetes spp.) that can add beauty to the landscape while taking care of the nematode problem. Research is described that concludes that root-knot nematodes can be controlled more efficiently if marigolds are planted close to a nematode infected plant or immediately into soil that was recently grown with root-knot nematode colonized plant hosts. This allows marigolds to release compounds that are toxic to the active vulnerable stage of root-knot nematodes.
