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.
This Center was initiated in 1925 as a one-man operation in Palmetto and
the first ornamental programs began about 17 years later. 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 vegetable 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 invest-
ment in independent programs.

An integral part of the overall mission of this Center deals directly with
the vegetable industries in Florida through research programs to (1) Develop
new or improving technology for more efficient production, handling and
utilization of vegetable crops; (2) Improve quality of products made avail-
able to the consuming public; (3) Develop technology and practices to reduce
environmental pollution without sacrificing quality during production and
thereby enhance man's environment; (4) Maintain and improve the productivity
of soils in the state of Florida; (5) Develop improved technology on uses of
ground water resources, solar energy and energy conservation practices in
agricultural production; (6) Develop information for all Florida growers
to compete effectively with other geographic areas of the nation and world;
(7) Advance basic knowledge of the various scientific disciplines represented
by the faculty; and (8) Assist the cooperative extension service, departments
in the College of Agriculture and other Research Centers with extension,
educational training, and cooperative research programs for the benefit of
producers, consumers and students.

Information presented in this publication 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 improvement and ideas of industry needs from our research and extension
programs.






Will E. Waters
Center Director









HISTORY OF THE AGRICULTURAL RESEARCH & EDUCATION CENTER BRADENTON


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

Tomato Disease Laboratory: In 1925 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 brach
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. In 1959 a 200-acre
tract was acquired 8 miles east of Bradenton. All of the vegetable experimental
field programs were moved to this new location.

In 1965, upon completion of 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 process 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 vegetable nutrition and culture, etiology and
control of diseases, and pasture research, while the latter is the hub of
strawberry research in Florida, including breeding, horticultural and
pathological studies.

Plants will be treated weekly with Manzate + Benlate for mildew
control. Foliar damage by melonworm larvae will be evaluated at
its peak incidence. All fruit will be examined for pickleworm
feeding injury.


Summary: Original selections were made in the spring of 1978 and were re-
evaluated fall 1978. The average % damaged fruit for plants of
chilton was 39% while that of selections from this cultivar was
29%. The average % damaged fruit for plants of Gulf Coast was
43% while that of selections was 31%. Differences in damage
were not great and may not be indicative of real resistance.

not resulting in holes in leaves.


Operation:


Plants will be sprayed weekly with Manzate. Cabbage will be sampled
on Monday and Thursdays, recording the number of holes or windows
on 10 whole plants pre-cupping and on the head plus 4 wrapper leaves
of 10 plants post-cupping. Plots will be sprayed with the respective
insecticides on Tuesdays and Fridays when the active thresholds have
been reached. Ten plants will be harvested and rated 1-6 for foliar
and head damage. Percent marketability (scores of 3 or less) will be
determined.


Summary: Experiments last year demonstrated that a visual threshold of 1-2 holes
per plant (pre-cup) or per the head plus 4 wrapper leaves (post-cup)
was equivalent to the old threshold of 0.1 larva/plant. This visual
threshold was established for permethrin and now needs to be determined
for other insecticides. Visual damage evaluations are much more rapid
than counting larval numbers.

Treatments:


,ck J


(A. A. Csizinszky)


Production of vegetables with soluble and slow release fertilizers
in a controlled seep irrigation system.
Optimum fertilizer rates and plant height for tomato production.
Amount of plant nutrients in the irrigation and runoff water with
controlled seep irrigation and changes in the fertilizer levels
of a vegetable land during a full year.

1) Fertilizer rates, varieties, within row plant spacings and
planting dates are the same as in G block with drip irrigated
vegetables and tomatoes.
Amount of irrigation water entering and leaving the land
measured daily. Waterflow is adjusted every day if necessary,
to provide adequate flow through the lateral ditches.
Other measurements taken are the same as in G block. At the end
of the season the efficiency of the controlled seep and drip
irrigation systems will be compared.
2) Treatments for the Floradade tomatoes in the fertilizer rate
experiments are the same as in G block. In addition, tomato
plants will be topped after the formation of the 15th hand in
one treatment and after the 20th hand in another treatment,
and kept at that height until harvest. Differences in fruit
size and weight will be measured and compared to tomatoes from
control plots where plants will be topped when they reach the
height of the stakes.
3) Water samples from the irrigation source and from the reservoir
where the runoff water is collected are taken once per month
and analyzed for 16 different elements. Soil samples are also
taken once per month from the vegetable land from 3 depths
down to the hardpan and analyzed for plant nutrient content.
From the variation of the elements in the water and soil
samples, the amount of nutrients in the runoff water and the
downward movement of fertilizers in the soil is measured.


Results: Incomplete.
