HARLEY BLACKWELL, AN INTERNAL HEAT NECROSIS (IHN) RESISTANT CHIP POTATO VARIETY FOR FLORIDA


'Harley Blackwell' is an internal heat necrosis resistant (IHN) chip potato selection recently released by the USDA. It was tested at the
University of Florida's Plant Science Research and Education Unit during five seasons from 1998 to 2003 originally under the number
B0564-8. Production practices followed standard IFAS recommendations.
'Harley Blackwell' tubers have consistently been described as having a tan to buff skin color with a netted texture. Tuber flesh color is
white to cream. Tuber shape is rated as 'mostly round' to 'round to oblong' with an eye depth of intermediate to shallow. Overall external
tuber appearance is noted as fair to good. Harley Blackwell plant architecture is described as spreading to upright with a good canopy.
Early plant vigor (size) is rated similar to 'Atlantic'. 'Harley Blackwell' and 'Atlantic' have a similar plant maturity rating. Overall, the tuber
appearance, growth characteristics, and maturity rating for 'Harley Blackwell' are similar to 'Atlantic'.
Total and marketable yield of 'Harley Blackwell' averaged less than 'Atlantic' over all seasons evaluated at the PSREU-Hastings Farm
(Table 1). In addition, specific gravity averaged several points lower than 'Atlantic' although still in an acceptable range for Florida chip
potatoes. However, IHN, a physiological disorder that discolors the tuber flesh, is less in 'Harley Blackwell' compared to 'Atlantic'. This
data were supported on commercial farm trials in 2001 in Hastings, FL. On four commercial farms, 'Atlantic' averaged 7.7% IHN compared
to 0.0% IHN in 'Harley Blackwell'. Total yield for 'Harley Blackwell' and 'Atlantic' averaged 330 and 360 cwt/A, respectively
(HortTechnology, 2003).
With the reduced yield but better quality of 'Harley Blackwell' compared to 'Atlantic', it is recommended that 'Atlantic' is planted to supply
early contracts when yield is important and IHN is less of a problem. 'Harley Blackwell' can be planted to fill late season contracts to
reduce the incidence of IHN and improve load quality.
A limited supply of 'Harley Blackwell' seed is available for the 2004 season through MFX, Presque Isle, Maine. As with all new varieties,
seed should be planted on limited acreage to gain information on the variety and to reduce initial risk.

Chip and Fresh Potato Variety Trial Report'.

DIVERSIFICATION IS THE KEY TO SUCCESS FOR THE LAST ZELLWOOD VEGETABLE FARM


Community Supported Agriculture, Agritourism, turfgrass sod, ornamental landscape plants, retail produce stand five years ago none of
these names could be attributed to Long & Scott Farms in Zellwood, FL. The farm was part of a group of 13 family farms producing
30,000 acres of vegetables for the wholesale market on mostly mucklands around Lake Apopka -then came the buyout. The St. John's
Water Management District bought most of the farms and shut them down in an attempt to improve the water quality in the lake. Long
and Scott decided not to sell since they farmed upland on sandland that did not impact the lake. They are the last remaining Zellwood
vegetable farm.


They have embarked on an aggressive programto diversify and improve profitability. First came the turfgrass sod and woody ornamental
additions both placed in areas that were not the best vegetable land. This segment of the farm replaced marginal vegetable production
with 350 acres of turfgrass and 5 acres of woody ornamental trees for the building and landscape market in the Orlando area.

The following season they added the Community Supported Agriculture program. Devoting about 20 acres to bio-rational production
methods for this venture gave them plenty of mixed vegetables for baskets either picked up at the farm or delivered to area farmers
markets. The first season had 40 subscribers from the area. They are now in their third season with 125 subscribers. The retail market
was added to the mix so that subscribers could not only pick up their baskets but buy other produce also.


This fall a new adventure was added to the mix a corn maze! Open from October through November, the "Let Freedom Ring" corn maze
features a statue of liberty with stars and stripes cut into a field of corn. For information, call 352-383-6900 or visit one of the web sites
below for more information on the success of Long & Scott Farm's diversification. Did I mention that this is the only place you can get
authentic Zellwood sweet corn now?

ORGANIC FARMING RESEARCH


The Organic Farming Research Foundation was founded in 1990 to foster the improvement and widespread adaption of organic farming
practices. OFRF sponsors research related to organic farming, disseminate research results and educate the public and decision makers
about organic farming issues. They have just released the 2nd edition of State of the States compiled by Jane Sooby. This report
documents organic farming research and extension being conducted in the U.S. land grant system. They concluded the top five organic
research states from 2001 are Iowa, Ohio, Minnesota, North Carolina and West Virginia. These states were singled out because they
have centralized organic research programs that are interdisciplinary, involve farmers in planning and decision making, have a systems
awareness, and are committed to transitioning research acres to certified status. In 2003, Washington and New York were added to the
above list of states. South Carolina, Maryland, Florida, and New Hampshire deserve recognition for their emerging organic research
programs.


Additional information and facts about each state's involvement in organic farming may be obtained on line at http://www.ofrf.org or
contact: Organic Farming Research Foundation, P.O. Box 440, Santa Cruz, CA 95061-0440, PH: 831-426-6606, FAX: 831-426-6670 or
EMAIL: research@(OFRF.org. A $10 donation is requested for a copy of State of the States. The following is the information they provide
for Florida.

another 40 acres are being held in reserve until needed. Scholberg's project is studying perennial peanut as a cover crop, as well as a
variety of other winter and summer cover crop species. Scholberg, PH: 352-392-1811 x 230, E-MAIL: jmscholberg@ifas.ufl.edu


2. Greg Jones, a doctoral student studying under Associate Professor Kathryn Sieving of the Dept. of Wildlife Ecology and Conservation,
is studying the use of organic fields by wild birds. Funded partially by OFRF, the study is a comprehensive assessment of how landscape
and farm-scale factors encourage insectivory by birds in fields. Jones is assessing the effectiveness of intercropping in enhancing native
bird populations and activity on organic farms. An earlier component of the study involved surveying farmers on their attitudes toward bird
conservation. The results of this were published in Jacobson, S. K., K. E. Sieving, and G. A. Jones. 2003. Attitudes and behavioral
intentions of organic and conventional farmers toward wild bird conservation. Conservation Biology 17595-606. A 2002 version is on the
web at http://edis.ifas.ufl.edu/UW169


The April 2002 issue of Linkages newsletter, a publication of the Center for Natural Resources, features articles on organic research,
including Greg Jones' research on organic and birds: http://cnr.ifas.ufl.edu/newsletters/Volume3/lssue10/default.htm. Contacts: Greg

3. Graduate student in Interdisciplinary Ecology Kristen Bowers received an OFRF grant in 2001 to study controls for the yellowmargined
leaf beetle, Microtheca ochroloma, in organic crucifer crops. A report is pending.


4. Russell Mizell at the North Florida Research and Education Center in Quincy received a 2002 Organic Transitions Program grant for the
project "Organic nursery production: development and demonstration." The project will develop and demonstrate organically-produced
plants in several specialty markets and address pest management as well as marketing. This project is scheduled to run through 2005.

5. Nematologist Robert McSorley has published scientific articles on controlling nematodes using crop rotations. He also co-authored a
paper on reflective mulch in organic bean production. His on-going research program, though not always explicitly organic, is aimed at
"improving non-chemical practices." Currently he is working on solarization and cover crops as alternatives to methyl bromide, and
comparing rates of organic nitrogen amendments (primarily legume hays) vs. synthetic N rates to improve N recommendations for organic
materials.

Education


The Center for Organic Agriculture (COA) opened in summer 2002 on the Gainesville campus. A 50-50 partnership between the university
and industry, the center will have educational, extension, and research responsibilities in organic agriculture. The Center emphasizes
interdisciplinary research and strong collaboration with the organic community. Plans include incorporating organic information into existing
class curricula; organizing new courses specifically on organic issues; providing internships for students interested in organic agriculture;
disseminating research-based information on organic; defining research needs as expressed by the organic farming community; and
facilitating multi-disciplinary research teams to address these needs. The organic research station land near Citra provides researchers
with a site on which to conduct certified organic research (see#1 under Research, Production, above). The entire project was galvanized
by a SARE grant made in 2001 to Florida Organic Growers'founder Marty Mesh, "Developing a model to increase support for organic
farming research at land grant institutions." Mickie Swisher, associate professor of sustainable agriculture and the statewide leader for
sustainable agriculture is the Center's director. Co-director is farmer Rose Koenig. Mickie Swisher, PH: 352-392-2201 x 256, E-MAIL:
