II. COMMERCIAL VEGETABLES

A. Advisory Board Sets Priorities.

The SW FL Vegetable Research and
Extension Advisory Board is made up of
vegetable growers and allied support
industry personnel whose directive is to
help the SW FL Research & Education
Center, and Charlotte, Collier, Glades,
Hendry and Lee county vegetable
extension personnel determine the
attitudes and opinions prevalent in the
vegetable industry. The Board (13
members) reviews research and extension
programming and offers advice to keep the
mandates in line with the needs of the
local industry. At the March meeting the
board prioritized the areas where they
believe the greatest research emphasis
should be put.


Priority #


1. Methylbromide alternatives the search
for a replacement (or systems approach) for
this soon to be banned soil fumigant and
suspected ozone depleter was top priority.

2. Whitefly/Virus Sweetpotato whitefly
and Tomato Mottle Virus were responsible
for $125 million in crop losses in 1992 and
possibly more in 1994.


3. Drip irrigation more research in this
area of technology and the efficiency
thereof was requested.

4. Thrips palmi few chemical controls
exist for this devastating insect pest of
southeastern FL and it is moving west!

5. Water use issues & regulations less
water for agriculture, ground water
contamination, and dwindling land/water
associations all concern growers.

6. Broad mite control this winter insect
pest that scars pepper fruit rendering it
commercially unusable has few chemical
controls.

7. Soil amendments composts, sludges,
etc. that may benefit production through
fertilizer reduction, increased water
holding capacity, and more need further
investigation.

8. Greater Cucurbit crop emphasis more
research on cucumbers, squash,
watermelons, and others.

9. Variety trials small scale trials give
growers some indication of which of the
many varieties might be best to grow.

10. Freeze protection what proven
methods are available when they are
needed?

11. Retention area maintenance how can
we better maintain storm reservoirs?

Those of us in vegetable programs
at the SWFREC appreciate these inputs
and will begin to direct research into those
priority areas not already under
consideration.

B. Pumpkin Varieties for Florida.

Pumpkins are grown mostly for sale
during October and November for
decorative purposes. Statistical data on
production in Florida are not available, but
it is estimated that only a few hundred
acres are grown in the entire state.
Production from this acreage is not nearly
enough to satisfy the demand, hence
considerable tonnage is shipped into the
state, primarily from the midwest.

Previous evaluations of pumpkin varieties
have been made in Florida but a number
of new varieties have been released since
those trials were conducted. Because of
the potential for increased pumpkin
production in Florida, an evaluation of 40
commercially-available varieties and six
advanced experimental lines was
conducted in the summer and fall of 1993
on a commercial farm in Manatee County.

Entries in this trial were mostly
typical Halloween pumpkin (Cucurbita
pepo) types even though fruit size ranged
from miniature to very large.

Six varieties; 'Big Max', 'Big Moon',
'Cinderella', 'Prizewinner', 'Rouge Vif
D'Etampes', and 'Snowball', although
frequently grown and used as pumpkins,
are actually squash (Cucurbita maxima).
'Buckskin' appeared to be still another
species (Cucurbita moschata).

This trial was conducted on a
commercial farm in Manatee County using
practices employed by the grower for
pumpkin production. Beds were formed in
early July by incorporating 200 lbs 2-18-4
(N-P201-K20) per acre and banding 1200 lbs
10-0-20 per acre on each shoulder of the
bed prior to application of white on black
polyethylene mulch. The final beds were 8
inches high and 36 inches wide and were
on 13 ft centers. On 21-22 July, pumpkin
seeds were planted through holes punched
in the polyethylene mulch at 2 ft in-row


spacing for short-vined varieties 'Baby
Bear', 'Baby Boo', 'Baby Pam', 'Jack-Be-
Little', 'Jack-Be-Quick', 'Little Lantern',
'Munchkin', 'Oz', and 'Sweetie Pie'- and 3
ft in-row spacing for all other entries.
Because of space limitations, five plant
plots were used for all of the experimental
entries,'Buckskin', 'Cinderella','Rouge Vif
D'Etampes', 'Spirit', and 'Trick or Treat';
ten plant plots were used for all of the
other varieties. Each plot was replicated
three times in a randomized block design.
Yields were converted to a per acre basis
prior to statistical analysis to correct for
different plot sizes.

Pumpkins were harvested 6 to 20
October. The miniature and very small-
fruited pumpkins were counted and
weighed in bulk and larger fruit were
weighed individually. Five representative
fruit from each plot were selected for
measurement with calipers and fruit rind
color was assessed by comparison with the
RHS Colour Chart. Later, these colors
were converted to a 0 (light yellow) to 5
(dark orange) scale for statistical analysis.

The number of fruit produced per
acre ranged from 484 for 'Thomas
Halloween' to 18,093 for 'Baby Boo'.
Thirty-four other entries produced a
similar number of fruit as 'Thomas
Halloween', whereas only 'Jack-Be-Little'
and 'Jack-Be-Quick' produced as many
fruit as 'Baby Boo'. The number of fruit
produced per plant varied from 0.4 for
'Thomas Halloween' to 10.8 for 'Baby Boo'
and 'Jack-Be-Little'. Thirty-three other
entries had fruit production per plant
similar to that of 'Thomas Halloween',
whereas 'Jack-Be-Quick' and PUXP 2001
produced as many fruit per plant as 'Baby
Boo' and 'Jack-Be-Little'. Fruit yield
varied from 37.1 cwt/acre for 'Oz' to 279.7
cwt/acre for 'Prizewinner'. Thirty-two
other entries had yields similar to those of
'Oz', whereas only 'Cinderella' yielded as
well as 'Prizewinner'. Average fruit
weight ranged from 0.2 lb for 'Baby Boo' to





-3-


35.3 lb for 'Prizewinner'. Fourteen other
entries had average fruit weight similar to
that of 'Baby Boo', whereas only 'Big
Moon' and 'Atlantic Giant' were as heavy
as 'Prizewinner'. Eighteen entries had
fruit with height:width ratios of 1 or
greater, whereas 28 entries produced fruit
with height:width ratios less than 1. The
range was 0.53 for 'Rouge Vif D'Etampes'
to 1.32 for 'October'. Rind color was
lightest in 'Atlantic Giant', 'Big Moon', and
'Jack-Be-Quick' and darkest in 'Baby
Pam', HMX 2690, 'Howden', and
JSS9032F1 in the yellow/orange rind
entries. Six other entries had similar light
color and 22 other entries had similar dark
rind color. 'Baby Boo' and 'Snowball' had
white rinds and 'Buckskin' had a buff
colored rind.

Pumpkin yields in this trial are
typical of those obtained in most previous
trials in Florida but lower than those
obtained at this location in 1992. The
general pattern of the highest per acre
yields being produced by entries that
produce very large fruit and the largest
number of fruit being produced by entries
that produce miniature fruit was repeated
in this trial.

Pumpkins of any size and shape are
saleable for decorative purposes. For the
jack-o-lantern trade, however, pumpkins
weighing at least 8 lbs and not more than
18 lbs are preferred. Larger fruit are
useful for individual display purposes and
smaller fruit often are used in combination
with other pumpkins and fall decorations.
In almost all cases, a bright or deep orange
color is preferred to a light orange or
yellow.


Outstanding entries based on
productivity, rind color, and suitability for
the decorative market in each size class
were:


Miniature:
<1 lb




Small:
1.0-5.0 lb


Medium:
5.1-10.0 lb




Large:

III. VEGETABLE GARDENING

A. The Garden and Landscape
Section FSHS.
Paper presentations are needed for
the 1994 Garden and Landscape Section of
the Florida State Horticultural Society.
The Annual Meeting will be held October
30 November 1, 1994, at the Clarion
Plaza Hotel, 9700 International Drive,
Orlando. Papers are scheduled for
Monday, Oct. 31, and Tuesday, Nov. 1.
The senior author and anyone
giving the paper must be a member of the
Society. (regular dues: $25.00). Also, the
speaker must be registered at the meeting
($50.00).
Twenty-five papers are needed in
this section. To present a paper, send a
150-word abstract to sectional vice-
president Jim Stephens (PO Box 110690,
Gainesville 32611) by June 1st.
1) Use a space 4 inches long by 6.5
inches wide.
2) First lines) are for authors' names
affiliation.
3) Underline author names and
asterisk the name giving paper.
4) Single space.

The Garden and Landscape Section
was established in 1972 and organized
similar to other Sections of the Society. Its
purpose was and is to provide growers,
advanced hobbyists, and technical and non-
technical members the opportunity to
publish.
According to John Popenoe of
Fairchild Tropical Garden (1972), the
FSHS originally was a society of amateurs
and horticulturists from all walks of life
and covering all phases of horticulture.
Papers were presented by hobby or
business growers rather than by
researchers. Much valuable information
was gained from keen observation.


Popenoe noted that over the years,
Florida horticulture became more
professionalized so the Society's Sections
became more scientific and rigid in
requirements. The gradual changes tended
to discourage the amateur from taking an
active part in the proceedings. He felt that
his backyard observations compared
unfavorably with a scientifically designed
experiment. Yet, astute horticulturists
realize that the field is so large that there
will always be a place for the observation
of amateurs.
That first year (1972) six papers
were given in The Garden and Landscape
Section. The first paper presented was by
Horticulture Extension Agent Louis Daigle,
and was all about how to have a superior
lawn in South Florida. It was not until 7
years later that a paper on vegetables
appeared. Herb Bryan and Bill Stall
introduced gardeners to a simple method
for fluid-drilling pregerminated seeds
(FSHS 1978).
During the period 1972 through
1992, there have been 332 papers
presented in the Section. Of these, 90
percent related to ornamental horticulture,
directly, or indirectly (see Table 1).
In keeping with the original intent
of this Section, I would like to encourage
all Extension agents, Master Gardeners,
and other amateur horticulturists to share
results of trial gardens, horticultural
projects, and general observations about
plants in typical garden and landscape
situations. Almost any topic relating to
horticulture has potential value for other
readers.
As the Sectional VP, I can help you
or anyone you know decide if your subject
for a paper is of value. Please call me at
904 392-1928 ext 209 or send in your
abstract by June 1.
