O‘ahu County Extension offers cover-crop field day

Although conventional farming practices call for clearing away all growth from fields whenever food crops aren’t in the ground, there’s a lot of evidence that growing cover crops can have many beneficial effects on soil health, plant nutrition, and pest control. Find out more about this sustainable practice at the Cover Crop Field Day.

Sam Choy’s in the Local Kitchen

Tune in Sunday afternoons for CTAHR ingredients and stories

A few years ago, local chef extraordinaire and co-founder of Hawai‘i Regional Cuisine Sam Choy had an idea for a new television show: eschewing high-end restaurant kitchens, he would visit the houses of local residents, invade their refrigerators, and whip up delicious dishes from whatever leftovers and neglected ingredients he could find there. His motivation was to decrease food waste by showing ordinary home cooks new ways to put together ‘ono recipes from foods they might otherwise have been tempted to throw away. The takeaway: don’t discount what’s right in front of you—it’s got more possibilities than you can imagine.

New techniques on cacao are getting a closer look

At Komohana Research and Extension Center there’s been a lot of cacao excitement! PIs Eli Isele and Alyssa Cho (both TPSS) have received an Applied Grafting Techniques grant from the County of Hawai‘i Department of Research and Development for a project comparing two hand-held machine-grafting tools with traditional grafting by hand using a knife to determine which are most efficient and cost-effective for avocado, cacao, and macadamia.

CTAHR-led pruning and pesticide trials help local growers

CTAHR faculty and staff, with the support of HDOA, USDA, and grower-cooperator Greenwell Farms, have conducted research trials on coffee-pruning techniques and pesticide residues in green coffee beans at the Kona and Mealani Research Stations. Information and outreach from both trials will increase farmers’ ability to manage coffee berry borer (CBB) and produce high-quality specialty coffee.

Preliminary results from the first year of harvest in the three-year pruning trial show that single or double vertical, hand-hedged trees provide nearly 1.5 times greater yield in the first season of harvest compared with Kona-style pruned coffee trees, and 3 times greater yield compared with stumped trees. However, pruning, de-suckering, and harvesting the hand-hedged trees also requires about twice as much labor.

CBB can be managed while using all these methods of pruning, provided that there is proper field sanitation in and around the farm and that Beauveria bassiana sprays are well timed and provide good coverage.

Results of the coffee pesticide residue trial determined that a synergist, piperonyl butoxide or PBO, was present in green (dried, unroasted) beans when coffee berries were sprayed up to 105 days pre-harvest. The PBO residues were greater than those allowed by export countries such as Japan. The researchers are recommending that growers avoid using products containing PBO on coffee so as to eliminate the risk of rejection for exported coffee to such countries. Other pesticides tested did not result in detectable residues in green coffee.

Project faculty and staff Stuart T. Nakamoto (pruning project), Andrea Kawabata, Matt Miyahira, Julie Coughlin, and James Kam are welcoming participants to meet growers and learn more about these and other coffee research and updates at the Hawaii Coffee Association Conference at the Ala Moana Hotel on July 25–28. CTAHR coffee project and outreach updates will be provided on Friday, July 26, and from the college’s educational booth throughout the event.

Cooperative Extension offers a seedling-propagating workshop

There’s nothing like the miracle of watching tiny dry grains sprout into lush green plants…and when they can provide healthful, sustainable vegetables, all the better! But making sure that the seeds sprout and caring for them until they become sturdy, strong plants aren’t always so easy. Find out how at the Vegetable Seedling Propagation Workshop.

Support for local 4-H garners national attention

The National 4-H Council ran a Raise Your Hand for 4-H promotion to raise awareness of all the great work that 4-H does with youth development. Supporters of the program could vote by virtually raising their hands in celebration of its myriad health, leadership, agriculture, and STEM programs for kids. While Hawai‘i 4-H didn’t win one of the top three monetary prizes, voters still put CTAHR on the map at the national level for generating the greatest percentage increase of hands raised compared with the 2018 promotion. For this, Hawai‘i will receive an Inspire Kids to Do photo shoot sponsored by National 4-H Council. 4-H’s Inspire Kids to Do campaign helps youth to grow into leaders through inspirational hands-on learning experiences.

Businesses and Childcare

For almost two-thirds of children under age 6 in Hawai‘i, all of their residential parents are in the workforce. For families with two keiki, childcare is the single most expensive budget item after housing. No wonder childcare is a key issue in work–family conflicts. CTAHR’s Center on the Family, along with partners, recently sponsored an event for local business leaders to learn about how employers can include childcare needs in employee benefits.

4-H for Health

4-H for Health

There’s a laudatory article on the many benefits of 4-H in the May–June issue of the Hawai‘i Island-focused Ke Ola Magazine—appropriate, since “ola” can mean “health,” and that’s just what one of the four H’s stands for. State 4-H program leader Jeff Goodwin estimates that 4-H reaches about 1,300 kids on the Big Island alone!

How Much Coffee?

Travis Idol and Adel Youkhana (both NREM) recently published a helpful paper detailing an easy and accurate protocol for estimating coffee yield in Hawai‘i. “A Rapid Visual Estimation of Fruits per Lateral to Predict Coffee Yield in Hawaii,” published in Agroforestry Systems Journal, allows farmers to predict the amount of their crop, a crucial task and an ongoing challenge, with less cost, time and labor.

Keeping the Ginger Flowering

Ornamental ginger crops are dying off on O‘ahu, but there’s no clear reason why—or rather, no single cause. At least six producers have asked CTAHR experts for help, but no common denominator has yet been found. The problem has been going on for about five years now, and researchers and producers are asking the Legislature for funding to research causes of the dieback.

Get Schooled on Farm-to-School

Want to know more about the state of ag education throughout the state—on every island, and from preschool up through graduate-level education and workplace mentorships? There’s no better way to find out than by reading the Final Report on a Coordinated Framework of Support for Preschool through Post-Secondary Agriculture Education in Hawai‘i. Submitted to the Legislature by the P–20 Ag Ed Working Group, of which CTAHR is a member, it details the many programs and initiatives helping kids, teens, and adults to learn how about gardening, farming, and caring for the ‘aina…and it offers bold new ideas for more.
