AGRICULTURAL RESEARCH & EDUCATION CENTER

ORNAMENTAL OPEN HOUSE

INTRODUCTION


On behalf of the faculty and staff, I extend to each of you a most cordial
welcome to the Agricultural Research and Education Center at Bradenton (formerly
The Gulf Coast Experiment Station). This Center, with affiliated Agricultural
Research Centers located in Dover and Immokalee, Florida, is a research and
education unit of the University of Florida's Institute of Food and Agricultural
Sciences.

In Bradenton we have 10 research scientists from various disciplines of
training who participate in ornamental plant research programs. Each research
scientist also holds a joint appointment with his subject matter department at
the University of Florida. This combination of a broad base of research disciplines,
industry contacts, and an excellent faculty makes the interdisciplinary cooperative
team approach to research problems far more productive than could otherwise be
accomplished with limited investment in independent programs.

An integral part of the overall mission of this center deals directly with
the flower industries in Florida through research programs to: (1) develop new
or improve existing technology for more efficient production and handling of
flowers, (2) develop technology and practices to reduce environmental pollution
during production and thereby enhance man's environment both by the products
grown and through better production methods, (3) develop information to allow
Florida flower growers to compete effectively with other geographic areas of the
nation and world, (4) assist the Cooperative Extension Service by providing new
information for use by both the producer and consumer, and (5) assist the
departments in the University of Florida College of Agriculture with educational
training programs.

Since the last biennial open house, our research capabilities have been
significantly improved through development of the following facilities: (1)
47' x 70' fiberglass transplant house; (2) 15' x 30' wood-glass ornamental plant
breeding greenhouse; (3) 30' x 60' aluminum-glass floriculture and nematology
greenhouse; (4) 16' x 20' insect laboratory; (5) 21' x 26' post-harvest physiology
laboratory; (6) three 8' x 8' walk-in cold rooms; (7) 24' x 24' tissue culture
laboratory; (8) 13' x 17' pesticide handling room; (9) 20' x 26' chemical storage
building; (10) 25' x 90' "Speedling" transplant production house; (11) installation
of 5 acres of permanent irrigation; (12) installation of centralized-automated
gas heating system for all greenhouses.

Information presented in this mimeograph summarizes the active research
projects under way this season. We sincerely appreciate your interest and support
of these research programs and continuously solicit your suggestions for improve-
ment and ideas of industry needs from our research and extension programs.

History of the Agricultural Research & Education Center Bradenton


Agricultural Research & Education Center Bradenton originated as the Tomato
Disease Laboratory in the fall of 1925.

Tomato Disease Laboratory: A 20-acre tract of county-owned property in Palmetto
was made available with the cooperation of the Manatee Board of County
Commissioners, with money and equipment supplied by local growers. Primary
objective of the laboratory was to formulate a control of nailhead spot of
tomato. Later studies emphasized the breeding for resistance to Fusarium wilt
and the control of tobacco mosaic on tomatoes. In 1937, with the expansion of
the vegetable industry in Manatee County and surrounding areas, the State
Legislature authorized new facilities for the research program.

Vegetable Crops Laboratory: In August 1938 the Manatee County Commissioners
donated eighty percent of the purchase price of a 106-acre tract on the east
side of Bradenton. This expanded program led to the establishment of the
Vegetable Crops Laboratory. Following this relocation, horticultural,
entomological, and soil studies were initiated on tomatoes, peppers, lettuce,
sweet corn, and other vegetables. Since the laboratory was located in the
gladiolus growing area, the scope was further broadened in 1942 to include disease
problems confronting gladiolus growers.

Gulf Coast Experiment Station: In March, 1951, at a meeting of the State Board
of Control, the Vegetable Crops Laboratory was given the status of a branch
station and was renamed The Gulf Coast Experiment Station. Investigations were
then initiated dealing with chemical weed control, nematodes, and other soil-
borne pests. The ornamental phase was broadened to include chrysanthemums and
other commercial cut-flowers.

In the late 1950's it became apparent that the facilities on the outskirts of
Bradenton were no longer adequate for the research program. A 200-acre tract
was acquired in 1959 8 miles east of Bradenton. All of the vegetable field
experimental program was moved to this new location. With the construction of
office and laboratory facilities, farm buildings, greenhouses, and a residence,
all research programs were conducted on this new land.

Agricultural Research & Education Center Bradenton: In 1971 the Gulf Coast
Experiment Station was renamed Agricultural Research & Education Center to
emphasize the programs of both research and education. Active programs are in
progress on production problems associated with vegetables and ornamentals
grown on the sandy soils of Florida.

AREC-Bradenton has administrative and research supervision over two satellite
stations: ARC-Immokalee (formerly the South Florida Field Laboratory) and ARC-
Dover (formerly the Strawberry and Vegetable Field Laboratory). The former
center specializes in aerial spraying of crops for disease control and also
plant nutrition while the latter is the hub of strawberry research in Florida,
including breeding, horticultural, and pathological studies.

Project No.: Fla-GC-1482


Title: Labor, material cost and returns for crops and livestock.

A. Investigator: T. S. Hipp

B. Objective: Continue to update the enterprise budget developed on gladiolus
and begin assembling a set of budgets for chrysanthemum production.

The methods employed in arriving at the cost of production when utilizing
the enterprise budget approach are as follows: (1) interview thoroughly
the research and extension personnel that are assigned to the crop or
enterprise,(2) through these scientists, line up a group of interested
and progressive growers who will cooperate in granting information about
everyday production practices,(3) assemble the production and cost
information representing the more efficient growers in such a manner as
to enable all growers to utilize the format, (4) conduct group meetings
with the cooperating growers and others wishing to attend to discuss the
accuracy of the numbers, (5) publish in the most concise form.

It should be stressed that an enterprise budget for any crop should
represent not only what is being done, but also, what can be done. The
numbers in the budget should be not only representative but should also
set goals for producers.
