To Bean or Natto Bean, That Is the Question

Soybean variety trial and hands-on workshop was a success

Natto…people love it or they hate it. Making natto is a good way to preserve soybeans, add nutritional content, create a value-added product, and produce a distinctive flavor and texture that some swear by…and others swear about. Participants at the recent natto workshop at the Pearl City Urban Garden Center were decidedly of the former camp, eagerly tasting different preparations of the sometimes-slithery fermented soybean condiment and learning how to make it themselves.

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.

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.

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.

The Care and Feeding of Your Lawn

Turfgrass expert explains how to keep your lawn green and happy

The Care and Feeding of Your Lawn

“I fought the lawn, and the lawn won…” If that’s your theme song, it doesn’t have to be. By sticking to a few simple principles, you can create, maintain, and manage a beautiful green lawn on your property.

Turfgrass Selection. Make sure to select turfgrass species or cultivars suitable for your growing conditions and expected use. Here are the most common species in Hawai’i, and their best selling points:

  • Bermudagrass does very well in the heat
  • Zoysiagrass is relatively low maintenance
  • St. Augustine grass has the best shade tolerance
  • Seashore paspalum can handle very high water or soil salinity.

If you don’t mind some variation in color or texture, you can try using a turf blend or turf mix, combinations of two or more cultivars of the same species or even two or more species, to get the best of both worlds.

Establishment. The best time to make major preparations and modifications to the soil is before you establish your lawn. Now’s when you can incorporate amendments like fertilizer and other nutrients, based on soil test recommendations, to provide the best possible growing conditions.

There are four main ways to establish a home lawn in Hawai‘i:

  • Growing from seed is the least costly, and it offers a variety of seed options. However, it takes the longest time, and you may run into the most weed issues during establishment.
  • Sod is fully grown turfgrass you can buy from sod farms—it unrolls over the ground like a carpet. This method is the most expensive, and selection is limited to the varieties that are locally available. On the plus side, sod offers instant lawn coverage and almost no weed issues during establishment.

The other two methods are compromises:

  • Plugs and sprigs are small pieces of turfgrass sod installed in the soil that grow together for eventual coverage. Plugs require consistent spacing between them; sprigs don’t need to be installed in any particular pattern. These methods work because all warm-season turfgrasses used in Hawai‘i spread horizontally by rhizomes (below-ground runners) and/or stolons (above-ground runners). Both cost less than sod and take less time than establishing a lawn from seed.

Weed control is essential during lawn establishment, especially when seeds, plugs, or sprigs are used.

Caring for Your Lawn. You can maintain high-quality turfgrass and minimize pest problems with appropriate mowing, irrigation, fertilization, and other cultural practices.

  • Mowing: If possible, follow recommendations for mowing height and frequency for your turfgrass. Usually the higher the mowing height, the more robust the root system and the better the overall health of the grass.
  • Irrigation: Too much or too little water can leave turfgrass vulnerable to pest problems. Deep and infrequent irrigation is usually better, while shallow and frequent watering promotes shallow rooting. If possible, water in the early morning rather than the late afternoon or early evening.
  • Fertilize your turfgrass as necessary, but avoid excessive nitrogen, which could stimulate some fungal diseases or result in weak grass blades that are susceptible to insect attack. When feasible, consider organic fertilizers, as they are typically slow release and could support soil microorganisms and improve soil food web health.
  • Thatch should be managed when feasible, and clippings can usually be left onsite.

Pest management. Insects, weeds, fungal diseases, and plant-parasitic nematodes are some of the most common turfgrass pests. Some common insect pests in Hawai‘i include the webworm, armyworm, cutworm, and fiery skipper caterpillars; frit fly; rover ant; mealybug; and bill bug. Common turf weeds are broadleaf weeds, grassy weeds, and sedges. Some common fungal diseases include dollar spot, rust, take-all patch, and fairy ring.

Try an integrated pest management approach, which includes deciding on an acceptable pest threshold, monitoring and early detection, and effective treatments to control target pests. If possible, try to manage lawn pests through a system approach: try cultural, mechanical, and biological control approaches before resorting to chemical pesticides. When using biological control products or chemical pesticides, always read and follow labels strictly. If you’re not sure about your lawn problems, ask a turfgrass expert or your local UH Extension service before taking any major actions.

Now, sit back and enjoy your lawn with a picnic or a game of bocce ball!
