Aloha,
Welcome to the Fall 2019 issue of Hānai'Ai, the Sustainable Agriculture Newsletter of the College of Tropical Agriculture and Human Resources (CTAHR) at the University of Hawai'i.
In this edition we are pleased to share some of the projects our CTAHR team and agriculture community have been working on to expand, promote, and improve local agriculture in Hawaii. Read about the application rates of biochar, disease management of banana production, cucumber and onion variety trials, FSMA inspections, upcoming events and more. We are here to help you with your farming needs! To visit the SOAP website,

EXPLORING BIOLOGICAL MANAGEMENT AGAINST FUSARIUM WILT OF BANANA IN HAWAII
Wang, K-H., N. Kerr, P. Waisen, and J. Sugano
University of Hawaii at Mānoa, College of Tropical Agriculture and Human Resources
Fusarium wilt, the lethal soil-borne fungal disease, is one of the most widespread diseases of banana. Fusarium is difficult to manage because the pathogen can survive in the soil for 20 years in the absence of the banana plants and survives in the banana plant residues. A project at the College of Tropical Agriculture and Human Resources examined two approaches of soil treatments against Fusarium. One being anarobic soil disinfestation (ASD), which has created interest in the agricultural industry, since it is compatible with organic agriculture. This paper discusses how CTAHR researchers investigated various approaches to manage the fungal disease Fusarium using ASD.

University of Hawaii at Mānoa College of Tropical Agriculture and Human Resources
Known as Soya Bean, Daizu, Dadou, and Kong, soybeans are known for their high nutritional value, oil and various uses. Typically soybea is used at the green shell stage as edamame. Soybean plantings is recommended to be around 6 plants/foot and 30in between rows. However smaller spacing 4-5 plants/foot and 15-20in between rows may lead to higher yields. Ten Soybean varieties were evaluated under windward conditions by CTAHR researchers for highest yielding varieties and Biochar application rates on soybean yields.

University of Hawaii at Manoa, College of Tropical Agriculture and Human Resources
Biochar is the product of burning organic waste at high temperatures (300-700C) with no or limited oxygen. The application of biochar has been reported to improve soil properties, increase plant growth and yields as well as reduce nutrient losses. CTAHR researchers evaluated five leafy green varieties for yield and biomass production under two different applications of biochar.

2019 MAUI SWEET ONION VARIETY TRIAL-SHORT-DAY LATE BULB ONIONS
Maui Cooperative Extension, University of Hawaii at Manoa, College of Tropical Agriculture and Human Resources
Bulb onions are one of the top commodities produced in the state, ranked 19th on Hawai'i's list of the top 20 commodities by value at $2.08 million in 2017 and ranked 2nd of the top 10 commodities imported by weight to Hawai'i. In March of this year Maui Agricultural Research Center staff performed a field trial assessing 8 varieties of short-day onion varieties. Read here.

What plastic mulch can help biofumigation to better manage nematodes?
Waisen, P., and K.-H. Wang
University of
Hawaiˋi at Mānoa College of Tropical Agriculture and Human Resources
A recent study conducted at the University of Hawai'i showed that macerating aboveground brown mustard tissues and incorporating into 4-inch soil depth followed by covering polythene black plastic mulch for 1 week suppressed plant-parasitic nematodes and improved soil health.

Organic Screenhouse Trial of Parthenocarpic Cucumbers
Preliminary Results April-June 2019

University of
Hawaiˋi at Mānoa College of Tropical Agriculture and Human Resources
There is high demand for locally grown cucumbers, however, cucumber production has its challenges. With pest management being a significant bottleneck, fruit flies and pickleworm mismanagement could have serious damages to the fruit, dramatically reducing yields. Many organic producers combat pest pressure with NOP-compliant pesticides, but overtime prove to be expensive, and frequent use can result in the development of pesticide resistance. Another option, Pest Exclusion strategies like screenhouses, can control pests and minimize the use of pesticides. Researchers at the College of Tropical Agriculture and Human Resources conducted a preliminary trial to evaluate the performance of five parthenocarpic cucumber varieties under organic production using a screenhouse.

FSMA INSPECTIONS HAVE BEGUN IN HAWAII
Kylie Tavares and Jushua Silva
University of Hawaiˋi at Mānoa College of Tropical Agriculture and Human Resources
|
In July, the Food and Drug Administration (FDA) began inspections of large farms on Oahu. Additional inspections are scheduled for Maui, Kaua'i, and Hawaii islands. Although these are the first round of inspections, inspections are expected to occur regularly and all farms are expected to comply to the Produce Safety Rule (PSR) by January 27, 2020. Inspections also include worker training for health and hygiene, cleaning and water system records, soil amendments of animal origin, and plans for wildlife management. To prepare farmers for these food safety inspections, UH Cooperative Extension Agents, with partners at the Hawaii Department of Agriculture and other groups, have conducted trainings regarding PSR and inspections.

Hawaii's Compost Reimbursement Program
The Hawaii Department of Agriculture (HDOA) has established the Compost Reimbursement Program which may reimburse agricultural producers for the cost of purchasing compost. Act 89 which was enacted in 2018, allocated $650,000 over a two-year period for the reimbursement of 50 percent of compost cost incurred by agricultural producers during a portion of fiscal year 2020 (July 1, 2019 to March 30, 2020) not to exceed $50,000 per applicant per year. Funds for the remainder of the three-year program have not yet been funded by the legislature. Under the reimbursement program, compost must be purchased from a certified processor, retailer or wholesaler licensed to do business in Hawaii. In addition, certified Hawaii processors are limited to those companies regulated under the Hawaii Department of Health's Solid Waste Management Program.For more information, please click
