ARCHIVED ISSUES


Aloha Kākou

Aloha Kākou, welcome to the Spring 2014 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.

It takes a community to make agriculture thrive. From crowd sourcing to seeking community involvement in submitting digital pictures to safeguard the Kamehameha butterfly...Yes, you can make an impact in safeguarding and expanding Hawaii's valuable agriculture industry. In this issue we highlight the ways community can support local agriculture.

Our featured farm, Ali'i Kula Lavender, has been a leader and innovator in agritourism, actively engaging visitors and kama'aina alike. In this issue we also feature great research on plant and soil health by CTAHR research and extension personnel. 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

Campaign for roof project

We need your help! Limited resources are pushing CTAHR to be more creative in how it goes about funding it's much needed educational and research programs that benefits everyone from kama'aina to commercial agriculturalists and conservationalists. That’s why we have put up a campaign on the crowdfunding site Indiegogo to raise money so they can raise the roof! And now they need supporters in CTAHR to raise some buzz about the campaign. Know anyone who wants to donate (even a few dollars) to a worthy cause? Point them in the direction of Waimanalo! There’s a little more than a month left on the campaign, plenty of time to get some shelter on the pavilion.


Featured Farmer: Koa Chang
Aliʻi Kula Lavender Farm, Kula, Maui

Ali'i Kula Lavender

Area under production: 13.5 acres, at 4,000 ft. elevation

Years farming in Hawaiʻi: 11 years

Crops grown, products/services: Lavender (Approximately 55,000 plant and 45 varieties) as the main crop, and recently, started to increase diversity on the farm to include: citrus trees, apple, plus about 10 more native plants, such as ōʻhia lehua, hibiscus, cane, taro.

Fertility Management: The farm depends on mixed management fertility, it depends on each batch/location of the farm needs and growth stage. In the recent years, the farm has been relying more on organic fertilizers and recycling (composting using Bokashi) and producing our own vermicompost.

Pest management: Mainly neem-based pesticides to control pests and it's been working very well for the plants.

Ti Leaf Diseases in Hawaii’s Commercial Orchards

Ti leaf with fungus

Ti leaf (Cordyline sp.) also known locally as Kī is an important agricultural crop to Hawaii. Laboratory and field trials which evaluated promising crop protection chemicals for possible minor crop fungicide registrations have been completed with the assistance of CTAHR’s IR-4 Minor Crop Pesticide Registration Program.

Soil Solarization as a non-chemical preemergent weed control tool on Oahu

Soil solarization

Josiah Marquez, UH-CTAHR TPSS, and Koon-Hui Wang UH-CTAHR PEPS

Soil solarization is a non-chemical soil treatment that utilizes solar radiation and a thin film of transparent mulch to heat the soil for soil pasteurization. Soil solarization has been studied as an alternative to chemical soil fumigant and as a pre-emergent control for weed seeds in the ground. This article discusses certain challenges of using solarization in the humid tropics and methods to overcome these obstacles. Read here.

Rhizosphere Inoculum and Amendment

Soil inoculant

Koon-Hui Wang, CTAHR PEPS

The frequent use of synthetic fertilizers and pesticides has lead to disruption of soil health, which often goes unnoticed. New generations of farmers are seeking profitable organic food crop production. Prohibitively high costs of organic fertilizers in Hawaii are providing incentive for farmers to utilize beneficial microorganisms to improve plant health. Many organic farmers are well aware of the benefits of beneficial soil microorganisms for farming. This handout introduces several approaches to invigorate soil microbial activities in agroecosystems to manage root health for profitable fertility and some soil-born stress or disease management. View handout here.

New Improvements on Coffee Berry Borer Management

CBB Infested coffee chaery

Andrea Kawabata and Stuart T. Nakamoto

Coffee Berry Borer (CBB) has the ability to decimate a coffee crop if left unmanaged. Proper control involves using an integrated pest management (IPM) approach where field sanitation, monitoring, spraying and timely harvests are of utmost importance. Learn about some important and updated CBB recommendations and tips from the 2014 CBB IPM Summit. Read here.

Producing High Nitrogen Liquid Fertilizer for Fertigation Purposes

Tankage

UH-CTAHR TPSS

Replacing imported fertilizers with local resources is the highest research and education priority identified by stakeholders throughout the Pacific. The production of locally derived nutrient solutions for fertigation will keep local farmers competitive, reduce water-use and loss, and protect the environment by reducing chemical use. The main objective of this study was to produce high nitrogen soluble fertilizer  for fertigation purposes using local organic materials. The lab results showed that locally produced tankage is potentially good, extractable sources of nitrogen. Incubation time, temperature, covering, and addition of vermicompost enhanced nitrogen release. Read here.

Performance of cool season cover crop in Lalamilo, Waimea, HI, Winter 2013-2014

Vetch flower: Vicia villosa

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. This project focused on evaluating performance of different species of cool season cover crops at high elevation growing condition in Hawaii. Read here.

Citizen Science Opportunities

Pic a Papaya app logo

Citizen Scientists can help CTAHR Researchers Scot Nelson and Richard Manshardt "Pic-a-Papaya" by helping us survey papaya plant populations in the Honolulu area for papaya ringspot disease (PRSV) and for plants with genetically engineered resistance to PRSV.

Download and use the free Pic-a-Papaya app for smartphones to snap pics of papaya plants and send them to Drs. Nelson and Manshardt for diagnosis of PRSV. Each plant will be assessed a value of healthy or diseased and its GPS coordinates mapped to a location in Hawaii. Users of the app can view the map to see the distribution of infected plants

Cucurbits are members of the gourd family (Cucurbitaceae) which includes popular crops such as cucumber, pumpkin, squash, melon and watermelon. Our lab needs to collect diseased samples from across the state of Hawaii to advance our research on this disease. This article explains downy mildew symptoms (plus photos) and gives instructions on how to participate in this research should you suspect downy mildew on your curcubits. Read more here.

The Kamehameha butterfly (Vanessa tameamea) is endemic to Hawaiʻi, meaning it is found nowhere else in the world. Although the butterfly is historically known from all the main Hawaiian Islands, it is no longer found in some areas where it used to be common (e.g. Tantalus on Oʻahu), and it appears to be declining. The Pulelehua Project is an effort to map current populations of the Kamehameha butterfly using observations submitted by the public, combined with surveys of remote areas by scientists.

We need your help! We are calling upon anyone who sees a Kamehameha butterfly, caterpillar, egg, or chrysalis to submit their photos and observations. Your data will be used to map the current distribution of the Kamehameha butterfly, and help determine how and why it has declined. You can also use this site to learn more about how to find and identify the different life stages and host plants of the Kamehameha butterfly.

Organic Update

At the behest of leading members of Hawai‘i’s organic industry, The Kohala Center applied for USDA Specialty Crops Block Development Grant funding, through the Hawai‘i Department of Agriculture, to conduct a Hawai‘i Organic Industry Analysis and generate a final report. The objective of the proposed project was to (1) conduct a needs assessment and study by soliciting stakeholder input and synthesizing of archival data, and (2) recommend ways to implement an economically self-sustaining organic program. The final report may be found here.
