Never one to pass up a challenge I did a search of the SARE projects
database at NCSU. The search turned-up the following on no-till pumkins.
Where it doesn't necessariy address Virginia, the document certainly
could direct your colleague to a reliable source of information.
I haven't tried searching the other large agricultural databases, but
I'm sure we can uncover some additional information.
How's this for speed? I'm returning this message within minutes of the
original query.

LNE89-19: REDUCED TILLAGE: ALTERNATIVE CROPPING SYSTEMS FOR

(Revised 1/14/91)
Major Participants:
Cornell University: Robin R. Bellinder (Project Coordinator),
research/extension, Dept. of Vegetable Crops, Ithaca, NY
14853. Weed Science, overall project coordinator,
responsible for the weed control and tillage aspects of the
projects in New York State, collaborator with the Michigan
project.
Long Island Horticulture Research Lab: Darlene Wilcox-Lee,
research/extension, Dept. of Vegetable Crops, 39 Sound
Avenue, Riverhead, NY 11901. Coordinator of the Long
Island projects and responsible for soil water aspects of
all studies.
University of Connecticut: Richard Ashley, research/extension,
Dept. of Plant Science, U-67, 1376 Storrs Road, Storrs, CT
06268. Coordinator of Connecticut projects, specialist with
regard to the cultural management of the living mulch
aspects of the studies.
Extension: Laura Pedersen, Cooperative Extension Agent, Ontario
County, 480 N. Main St., Canandaigua, NY 14424. Ms.
Pedersen has been a proponent of ridge-tillage for snap
beans for number of years so when I approached her with this
project she joined in willingly. Thanks to her efforts Mr.
Wafler joined the team. She will be an active participant
in all field days and extension activities.
New York State Agricultural Experiment Station: Curt Petzoldt,
Assistant Director, IPM Program, Geneva, NY. Dr. Petzoldt
has been interested in other reduced tillage work that has
been done in the Vegetable Crops Weed Control Program and
has acted as an adviser in the planning phase of the
project. He will actively participate in the demonstrations
(to be done in growers' fields in 1990 and 1991) and
educational events.
USDA/Soil Conservation Service: Alan Connell, District
Conservationist, Riverhead, NY. Will provide technical
expertise in soil water measurement and the determination of
soil erosion potential under various ground covers. In
addition, he has provided valuable assistance in obtaining
grower participation in this project.
Comstock Foods: Gerry Ivison, Field Manager, Bergen, NY. This
is the company that processes Craig Yunker's organic
vegetables for Earth's Best Baby Foods. Mr. Ivison's
expertise with both growing and processing concerns will
make him an excellent consultant. He is also providing us
with the seed we need for the pea project.
Farmer Participants:
Lyle Wells, Riverhead, NY, member of the Board of Directors of
the New York State Vegetable Growers Association. Mr. Wells
has been particularly interested in producing no-till
pumpkins and approached us with his interest. He has been
invaluable in the early discussion phase of the project and
will be a participant in the field trial phase.
Paul Wafler, Wolcott, NY. Mr. Wafler is one of the courageous
few willing to experiment with the idea of reduced tillage
vegetable production. He has participated in the early
planning phases of the snap bean studies and has already
planted wheat and hairy vetch mulches for this first trial
in 1989.
Craig Yunker, CY Farms, Elba, NY. He has an interest in growing
vegetables organically. He has grown both snap beans and
peas for several years using organic methods. He will act
as a consultant to our organic peas study and will grow two
14-acre plantings of peas in a plowed down alfalfa sod in
1991.
Overview
We are proposing to investigate the use of reduced and
strip-tillage with interrow cover crops for vegetable production
in the northeast. The research will be conducted at research
facilities and growers' fields in upstate New York and on Long
Island, and in Connecticut.
We will evaluate different grass and legume mulch/cover crop
species for their ability to suppress weeds, conserve soil
moisture and control soil erosion. Crop performance in each of
the mulch systems will be determined and herbicide rates will be
reduced utilizing the weed-suppressing potential of the mulches.
The studies will be conducted on a wide range of crops that
are grown throughout the northeast and north central regions of
the US. We will include tomatoes, cabbage or cauliflower, snap
beans, sweet corn and pumpkins at multiple locations. The
proposed research will help to define the specific requirements
for reduced-tillage vegetable production that will be necessary
if growers are to consider using such systems. Formulation of
such recommendations in combination with the extension and
education efforts involved in this project should provide
commercial interest and participation in a system with both
economic and environmental advantages.
Objectives
We are proposing to investigate the use of reduced and
strip-tillage with interrow cover crops for vegetable production
in the northeast. The specific objectives of the proposed work
are:
(1) Evaluate potential cover crop/mulch species for their
ability to suppress weeds, conserve moisture and reduce
erosion. Growth characteristics like rate of growth,
biomass production, degree of tillering and plant
architecture will have a significant impact on the degree of
weed suppression and soil and water conservation achieved.
For example, the vertical architecture of the grass mulches
may allow more water evaporation than the horizontal covers
provided by legumes. Conversely, the potentially greater
moisture under the legume mulch may enhance weed
germination. Differences in light penetration in the two
mulch types may result in changes in the species of weeds
that germinate and develop.
(2) Determine the yield potential of numerous vegetable crops
grown throughout the northeast when produced in strip or
reduced tillage systems. Numerous problems have been
reported when vegetables are grown in no-tillage systems.
Three of the commonly reported problems are poor seed-soil
contact or coverage; cold soils preventing germination; and
reduced root development. We feel that the use of strip
tillage, particularly coupled with the use of a chisel tine
in the strip, will alleviate these problems. Our goal is
not to obtain increased yields in these systems but to
obtain yields equivalent to those currently produced with
traditional plow/disc cultivation systems.
(3) Utilize the weed suppressing potential of a mulch to reduce
rates of applied herbicides. In order to significantly
reduce the chemical load on the environment we must convince
large-scale commercial vegetable growers that herbicide use
can be reduced without a reduction in yields (profits).
Through a combination of physical and allelopathic
characteristics some mulches prevent or suppress weed
germination and/or growth. Delaying weed emergence by four
to six weeks would eliminate the need for most soil-applied
preemergence herbicides. Coupled with the currently
labeled, highly selective post-emergence herbicides, growers
can begin to apply herbicides at low dose on an as-needed
basis as is done with insecticides and fungicides in
traditional Integrated Pest Management Programs.
(4) Compare costs involved with each mulch/tillage/herbicide
system. Each mulch used will require a different management
approach; spring oats will winter-kill; hairy vetch will be
mowed; and the remainder will require chemical regulation.
It will be necessary to calculate all inputs into the
system: man and machine time, fuel and chemical inputs,
etc. It may prove that reducing the chemical inputs in
dollars will be offset by increases in the other areas,
however the benefit of reducing the chemical load on the
environment and of reducing soil loss must also be factored
into the economic equation.
Project Duration: Two years: 1991-1993
