OKRA PRODUCTION GUIDE

Okra is grown in Florida in the home guard
and commercially for consumption as a fresh, fr
zen or canned product. It will grow and produ
good yields during certain seasons in all location
in Florida. It is adapted to all soil types four
in Florida, but performs best in rich sandy loan
with pH between 5.8 and 6.2. Extensive acrea{
is grown on rockland soils of Dade County. Oki
will not thrive during periods of cool weather ar
is killed by frost. The most important limitir
factor in okra production is usually the crop
susceptibility to nematode injury.
For additional information, the reader is
reacted to the following publications:
Florida Extension Circular 225, "Comme
cial Vegetable Fertilization Guide."
Florida Extension Circular 193, "Comme:
cial Vegetable Insect and Disease Control Guide
Florida Extension Circular 196, "Chemic,
Weed Control for Florida Vegetable Crops."
Since these circulars are revised from time 1
time, be sure to obtain the latest editions.
VARIETIES
Clemson Spineless-A standard variety; use
for fresh market and as a frozen product. Poc
straight with short taper at tip, spineless, ridge(
rich green in color, good quality and uniforrr
plants are 4 to 5 feet tall, relatively free of spine
and bear sparse foliage.
Other Varieties-Perkins Dwarf Spineless an
Emerald.
PLANTING
Planting Dates Days to
Maturity
North Florida: March-May; Aug.
Central Florida: March-May; Aug. 50 to 60 da3
South Florida: Jan.-March; Aug.-Oct.
SEEDING
Planting Distances Depth Seed Required
Between rows 1/2" to 1" Per acre 3 to 10 Ibi
36" to 48"
Within the row- Per 100 ft. row -2 o:
2" to 6"
FERTILIZATION
Placement-Recommendations in the past hav
been to place the main or basic application o




rtilizer normally used at planting in bands 2
3 inches to each side and slightly below the
vel of the seed. This practice is good where
>luble salt injury is not anticipated. An alter-
tive practice, which helps alleviate soluble salt
problems, is the use of broadcast applications for
art or all of the basic fertilizer before planting.
Timing-The basic application of fertilizer
ay be applied before planting, during planting,
shortly after planting, or in split applications
combining any two or all three of these. Supple-
ental fertilizer may be applied whenever needed
during the growing season and especially after
heavy, leaching rains.
Soil pH-Optimum range for okra production
between 5.8 and 6.2.
Minor Elements-In the absence of previous
history and experience on sandy soils, a "shotgun"
approachh can be used. A general guide for ade-
uate minor elements is the addition of 0.3%
nIn0, 0.2% CuO, 0.3% Fe,03, 0.2% ZnO, and 0.2%
03O to the fertilizer mixture. These elements
an be used as the oxides, sulfates, of fritted
,orms. Use minor elements only as needed for
,ucceeding crops.

1 Includes all mineral soils (except marl and rockland)
having a dependable supply of moisture.
2 Includes all mineral soils (except marl and rockland)
not having a dependable supply of moisture.
3 The amount of fertilizer suggested here is the amount
needed for organic soils low in POs and KO. When soil
tests show a medium level of PO, in an organic soil, re-
duce the amount of PO-, suggested here by one-third;
when soil P O, levels are high reduce by two-thirds. Fol-
low the same suggestions for medium and high levels of
K-0.


Higher rates of the minor elements may
needed to overcome the tendency of minor el
ments to be tied-up by the organic matter in muc
and peat soils and from the high pH effect o
marl and rockland soils.
The amount of fertilizer suggested here
sufficient to grow these crops under normal con
editions. Most crops will respond to supplement
applications of nitrate-nitrogen during periods o
cool weather or following heavy rainfall.
On new peat soils, make a broadcast applica
tion of 15 pounds of CuO, 10 pounds of MnO, an
4 pounds of B0O, per acre before any crop
planted.

DISEASE CONTROL
Relatively few diseases attack okra. Occasion
ally, Fusarium wilt is present on old land. I
Dade County, Verticillium wilt is a serious dis
ease. A good rotation program will aid in reduce
ing the damage from wilts and other soil-born
diseases. Powdery mildew is sometimes a prob
lem; however, no fungicides are approved by EPA
for its control on okra.
Precautions: Read the label on each pesticide
container before each use. Heed all cautions and
warnings. Store pesticides in original labelled
containers promptly and safely. Information is
given on recommended pesticides and minimum
days between last application and harvest. There
will be changes and cancellations; therefore, the
grower is urged to keep abreast of developments
through county extension agents, experiment sta-
tions, industry, etc.

WEED CONTROL

Trifluralin (Treflan)-Applied preplanting,
3/4 to 1 pound per acre (active ingredient) on
sandy soils. Trifluralin should be incorporated
immediately after application. Use the lower rate


on sandy soils low in organic matter and th
higher rate on sandy soils high in organic matter
The 1 pound per acre treatment can also be use
on the marl and rockland soils.
Diphenamid (Dymid or Enide)-Applied pre
emergence, 5 pounds per acre (active ingredient)





HARVESTING AND HANDLING

Okra pods generally reach prime condition for
harvesting in 4 to 6 days after flowering. Pods
should be harvested when they are from 3 to 4 in-
ches long. If allowed to remain on the plants an
extra day or two, the pods become too tough and
fibrous for food. For that reason, plants must
be harvested daily or on alternate days. Large
and undesirable pods should be removed to permit
the plant to continue to bear over a long period.
Okra can be kept satisfactorily for fresh con-
sumption over a two-week period at a tempera-
ture of 500F. and a relative humidity of 85 to 90
percent. At temperatures lower than 50F. okra
is subject to chilling injury, evidenced by surface
discoloration, pitting and decay.



This public document was promulgated
at an annual cost of $214.90, or 2.86
cents per copy to inform growers how
to produce okra.
