Bill Miller explains flower bulb research to Oregon farmers.

Bill Miller explains flower bulb research to Oregon farmers.

Reposted from CALS Notes:

The Cornell University Agricultural Experiment Station (CUAES) recently hosted over two-dozen farmers and producers from Oregon who visited Cornell as part of an agricultural education tour of New York State. The tour, sponsored by the AgriBuisness Management Program of Chemeketa Community College in Salem, OR, started with an overview of the energy efficient growth chambers in Weill Hall given by Nick Van Eck, growth chamber supervisor.

“Instead of using electric heat and refrigeration,” Van Eck explained, “the temperature of these chambers is regulated by utilizing campus chilled water and hot water that heats the building.”

The tour continued to the greenhouse complex, where Neil Mattson, associate professor of horticulture, showed off spring trials being conducted as part of his research comparing the efficacy of organic vs. conventional fertilizers in the production of bedding plants and vegetable transplants.

“We compared the performance of tomato and pepper seedlings to four different commercially available vermicompost materials. Not all materials are suitable for use as the sole fertility source, but we found excellent performance from Worm Power, a New York state company and one of our grant collaborators.”

Mattson also noted that controlled release fertilizers and slow release organic fertilizers can be an effective way to reduce nutrient leaching to the environment.

Elsewhere in the greenhouses, Bill Miller, professor of horticulture and research director of the Cornell Flower Bulb Research Program, demonstrated how the growth regulator ethephon helps to keep flowering plants like hyacinths and daffodils shorter and stockier so they hold up better during shipping and sale (pictured).

Other presenters included Department of Horticulture faculty members Ken Mudge and Marvin Pritts, CUAES Director of Operations Glenn Evans, and James Tanaka of theCornell Small Grains Breeding Project.

A new study reports that children in schools with vegetable gardens got 10 minutes more of exercise than before their schools had gardens.

A new study reports that children in schools with vegetable gardens got 10 minutes more of exercise than before their schools had gardens.

To get schoolchildren moving, uproot them from classrooms into school gardens, concludes a two-year Cornell study of 12 elementary schools in five New York regions.

By experiment’s end, kids at schools with gardens were moderately physically active at school for 10 more minutes a week than before their schools had gardens. That was an increase of four times what peers experienced at gardenless schools. What’s more, children who gardened at school were substantially less sedentary at home and elsewhere than their counterparts.

With nearly one in three American children overweight or obese, school gardens could be a simple, low-cost way to get kids more active, said environmental psychologist Nancy Wells, associate professor of design and environmental analysis in Cornell’s College of Human Ecology.

Strawberries in quart basket

New strawberry selection NY01-16 now available for testing

On behalf of Dale Ila M. Riggs, President, NYS Berry Growers Association and Dr. Courtney Weber, NYSAES Small Fruit Breeder via the Cornell fruit news and events blog.

Two years ago, the NYS Berry Growers Association and Dr. Courtney Weber from Cornell’s Small Fruit Breeding Program entered into an agreement where members of the Association will be able to “test drive” advanced selections from Courtney’s breeding program.  This is a phenomenal opportunity for all members of the Association and will make it possible for members to try potential raspberry and strawberry varieties before any other member of the grower community has the opportunity.  This is a huge competitive advantage!

The NYSBGA and Courtney are now seeking growers that want to evaluate and provide feedback regarding the second advanced selection from Courtney’s strawberry breeding program under this agreement.  The selection, NY01-16,is very large for the early mid-season. The largest fruit were 51 g (almost 2 ounces) without irrigation. Subsequent fruit hold their size well. The fruit have very aromatic flavor, are slightly dark red, firm, with an attractive conic shape.  In 2013 it started fruiting on June 4 (one week prior to Jewel) and fruited until about July 1.

If you would like to trial this selection, you must be signed up as a member of the NYSBGA by April 1.  If you are not a member, contact Paul Baker, Executive Secretary for the NYSBGA (716-807-6827) to get signed up.  You can also download a membership form from http://www.hort.cornell.edu/grower/nybga/MembershipBlank.pdf.  After your membership has been confirmed, Paul will need your address, your shipping address, and your requested date for shipment.  As part of the evaluation process, a one page site report form and a one page fruit/plant evaluation form will be submitted to the Berry Growers Association and the data will be forwarded to the Small Fruit Breeding program.

This is a wonderful opportunity brought to you by the NYSBGA and Cornell.  Cornell is excited about being able to get data to see how advanced selections perform in commercial situations.  Members can get a minimum of 1000 plants to a maximum of 2000 plants to test on their farm.   Don’t miss out.  Contact Paul Baker today!

Ornithogalum research at KPL greenhouses

Ornithogalum research at KPL greenhouses

From Neil Mattson and Bill Miller:

We invite you to attend a free, informal open house at the Cornell campus to highlight some of the greenhouse research being conducted there. Come visit our trials and talk with Bill Miller and Neil Mattson. The open house will be held from 9 a.m. to 12. noon on Tuesday March 18, 2014 at the Ken Post Lab Greenhouses. Come and go as you please!

In addition, the nearby East Ithaca high tunnel facility (about 1 mile from campus) will be open to tour with Chris Wien from 11 a.m. to 12 noon.

Directions,  parking and more information.

Greenhouse trials in progress

  • Spring bedding plants growing with different rates of liquid, organic, and controlled release fertilizer
  • Comparing different vermicompost materials for vegetable seedlings and transplants
  • Cut flower callas and response to GA treatments and silicon
  • Testing PGRs for height control of daffodils, hyacinth, and tulips
  • Ornithogalum potted plants and response to temperature and PGRs
  • Hydroponic spinach and lettuce

High tunnel trials – not much green yet!

  • Anemone and ranunculus for early spring cut flowers
  • Overwintering trials with dahlia and eucomis (pineapple lily)
  • Check out the high tunnel structure where Mattson has conducted trials with finishing spring bedding plants with no heat

ApplesTart2-19aCornell Chronicle article by Amanda Garris details three projects funded by the USDA’s Agriculture and Food Research Initiative (AFRI):

  • A $410,000 AFRI grant will allow Kenong Xu, an assistant professor of horticulture at Cornell’s New York State Agricultural Experiment Station in Geneva, to analyze the function of the likely gatekeeper of apple acidity, a gene called Ma1. The research was prompted by Cornell apple breeder Susan Brown, Cornell horticulture professor Lailiang Chang and Miguel Piñeros, a research plant physiologist with the U.S. Department of Agriculture’s Agricultural Research Service are both co-leads on the project.
  • A $500,000 AFRI grant will allow breeder Martha Mutschler-Chu to deepen her understanding of different types of acylsugars – sugars produced and exuded from hairs (trichomes) that cover wild Peruvian tomato plants – and how they might impact insects in different ways. That, in turn, could lead to developing additional lines of tomatoes with targeted resistance to specific pests, which would substantially reduce pesticide usage and tomato production costs.
  • A $450,000 AFRI grant will allow Michael Mazourek , the Calvin Noyes Keeney Assistant Professor of Plant Breeding, to create varieties of squash with high levels of carotenoids and carbohydrates. Using transcriptome sequencing, metabolite analysis and a unique barcoding and phenotyping system developed in his lab, Mazourek will determine the genetic basis of variation in fruit quality of three types of squash and a pumpkin.
