To make a success of raising vegetables of any kind
out the most important thing to consider is "how to sell
em at a profit" to the producer.
The market gardener as well as the truck farmer should
r to put himself in the position of the buyer. What
uld you like to get for your money if you went to a
,rket or a store to purchase vegetables for your home?
)uld you want the stale, wilted or dried-out vegetables
It are sometimes offered the housewife?
Of course, the final condition of the vegetables you
se is not entirely in your hands. You cannot always
*esee just what the commission merchant, or the vege-
)le stand, or the store will do with the vegetables after
ey are delivered to them, but a great deal depends on the
,nner in which the vegetables are first prepared for
.rket. If you will be absolutely sure that you have first,
rvested at the right stage of maturity; (the most im-
rtant step in marketing), second, properly graded the
getables, third, packed them in the right kind of crates,
skets, or containers, fourth, neither underpack nor over-
Ak them (what we mean by this is-not too many nor
Sfew of the articles in the crate), fifth, pack them as soon
er picking as humanly possible, sixth, deliver them to
- express office, (if you are shipping by express) or to
e motor truck for immediate shipment,-a great deal
11 be added to the value of vegetables you ship.
Much has been written and said about this very im-
rtant feature in the handling of vegetables and still, if all
the truck gardeners and farmers could go through the
ge commission houses and see first hand the poor qual-
of many shipments of produce sent to market they
uld realize why this instruction is repeated.
Luther Burbank is quoted as saying: "I do not blame
e housewife for not wanting to cook some of the wilted,
or quality vegetables that are offered them."
Harvest the vegetables when you know they are in
)per condition to stand shipment.

Don't take the risk of having your crop spoil in
Next, grade correctly, pack and ship promptly
vegetables will remain in good condition a much
time. The old adage: "one bad apple remaining
barrel will spoil the entire barrel" will always be tn
bad bunch of vegetables will spoil the entire crate.
You are producing vegetables as a means of i
so study every phase of your procedure.

Market Gardening and Truck Farming

Olericulture as a general subject could be correctly
parated into two divisions and designated as market
rdening and truck farming. Most encyclopedias and
ctionaries make no distinction in their definitions, but
irket gardening which has as its object the raising of
rge quantities of many varieties of vegetables for local
irkets should be differentiated from truck farming.
Truck farming which may be restricted in the variety
products raised is conducted on a more extensive scale,
e production being confined to a few standard crops for
ipment to distant markets. The acreage returns are
eater in truck farming than in market gardening.
Vegetables in this state are now being raised as a mar-
t gardening product as well as a truck farming product.
Irrespective of how vegetables are raised, quick trans-
rtation facilities and good markets are most essential for
access. Without efficient, fast transportation develop-
nt of truck farming would be impossible.
It is a trait of human nature to want something new
d this is no exception to food products. A new vegetable,
lew fruit, or a new canned product finds ready accept-
ce. Continued good quality will result in a permanent
Ice for the article after it has been properly introduced.
Those varieties of vegetables which ship well and which
lture during the season when there is a shortage of
ler fresh vegetables, and which are adapted to the cli-
.tes of the South, and particularly to certain districts of
)rida, will find ready acceptance on a great many of the
;t markets of the North and East.
However, truck farming or market-gardening depends
:n the man just as it does in any business. A good crop
)wer must be a good businessman. He should thor-
ghly know his business and have such knowledge that
will be able to overcome difficulties in crop-production
I understand marketing in all its details.
Before producing any product for market there should

supply. It is most risky to plant a large acreag
hope that labor will be available when the crop :

Crop rotation is necessary for successful opt
Any soil will wear out if used continuously to proi
same crop. Every time a crop is raised there g(
the crop certain elements of plant food from the i
unless land is given an opportunity to rebuild and
sisted through the proper application of fertilih
land so used will not produce a profitable crop.

We want to recommend that the prospective I
of vegetables for the market write the Department
culture, Tallahassee, Florida, for a copy of their
No. 3, entitled "Soils and Fertilizers." Study this
thoroughly and give particular attention to pages 5
9, 10, 11 and 48, 49, 50, 51 and 52.

A great many vegetables are subject to the sai
of diseases and the same insect enemies. Send to
apartment of Agriculture, Tallahassee, Fla., for the
tin, "Plant Diseases and Pests and their Treatmei
study it.
Land that has become infected with organism

iduce plant diseases must be abandoned until the disease
iducing organisms can be starved out. Such organisms
re the ability to perpetuate themselves year after year,
I for the reason that they develop in the plant tissues
y cannot be exterminated, nor in fact treated to any
Free of success through the external applications of
pounds used sometimes for the purpose.

Crop succession as a rule is more important to the
rket gardener than to the truck grower. Truck growers
d it advantageous to have two different crops growing
the same time. Double cropping or catch cropping is
[owed on high priced land. This makes possible a series
crops from the same acreage. Sometimes four crops
produced from the same land during a single year in
alities having long growing seasons.

Soil character determines to a great extent the length
maturing of the crop irrespective of climatic conditions.
Id retentive soils will be late in maturing a crop while
rm, light, sandy soils will produce an early crop. The
d, heavy soil that retains its moisture cannot be culti-
;ed as early in the season as the light, sandy soil which
es out more speedily.

When planting seeds in cold soil do not expect them to
rminate as quickly. Likewise the plants will not grow as
)idly. Your plan of growing and marketing should de-
mine the nature of soil preferable for your production.
ne crops demand a cold, retentive soil but that is some-

insect enemies and plant diseases on growing plants and

also the effect of fertilizers and moisture supp
them, we believe some information on plant struct
prove most valuable. Plants are composed of th
tinct parts, two above the ground and one beneath
These parts are known as the root, stem and leal
part of the plant performs certain functions ii
relation to the others.

The root function is both mechanical and physi
The mechanical function consists of furnishing an
for the plant and the necessary support to the stein
in turn carries the leaves. The physiological fur
properly classed as being of greatest importance
function covers the selection from the soil of tU
mineral foods necessary to plant growth. Some ,
foods are nitrogen, potash, phosphoric acid, lim
nesia, silica, iron and sulphur. Elements such ,
are obtained from the soil in what is termed soluti
they are carried in water, through the growing ti,
the roots. This tissue is generally restricted to th
near the tip of the root system. The rapid deve
of crops is possible through a good actively grow:
system. Since this development of vegetables is t
desirable feature to the growth it is of prime imj
that the soil conditions should be kept in such c
as to induce rapid growth.

The stem is the frame work which supports th(
flowers, and later the fruit and it also conducts
leaves and other parts of the plant the food elemen
ered through the root system. There are two sys
ducts in the stem which serve as carriers for th
materials in solution, one of which supplies the
flowers and fruit and the other which carries bad
various parts of the stem and the root system those
food elements which are used in building addition
tissue and roots, or they may be stored up in tl
structure for future use. From this it will be seen -
mechanical function of the stem is the most prone

The functions of the leaves of plants are the mc
plex of the many delicate organs of plants. Regar

whether leaves are broad and thin or otherwise constructed
ley have a proportionately large area that is exposed to
ir and sun. With but few exceptions leaves of plants are
green in color, providing the plant itself is in a normal
healthy condition. This surface area of leaves over which
lis green tissue is spread contains a very large number
E small openings, noticeably on the under side of the
aves. It is through these openings that the plant breathes
r takes in air as well as moisture. It is likewise through
these same openings that excess moisture is exuded.
Whenever the excess moisture is not disposed of the plant
ill become affected with edema and will appear drooping
nd somewhat wilted.
Minute microscopic bodies contained in the cells of the
aves give them their green color and they also serve to
build the outer layers of the leaf. These minute green
dies are known as chloroplasts and when present in cor-
ect quantities give the plant its healthy, characteristic,
reen color. The function of these microscopic bodies found
i the cells is the most important of any connected with
[ant growth. Sunlight enables these chloroplasts to take


anchored in the trenches. Boarding up the ends of the
structure and covering the roof with Spanish moss or
other materials completes this inexpensive root cellar.
Value of Florida Truck Crops
The combined value of the truck crops grown each year
in Florida exceeds that of citrus fruits, giving vegetable,
melon, and other truck crop production in Florida the po-
sition of first importance in value of income to growers in
the State.
The list of vegetables and the varieties, grown in Flor-
ida is a long one, and only some of the most important
crops will be included in this publication.
The Department of Agriculture at Tallahassee, Florida,
have prepared special bulletins on a large number of crops
grown successfully in the State and if this bulletin does
not contain the information you desire it is suggested that
you write the Department of Agriculture and they will
forward information on any crop that can be produced here.
One of the universal crops of Florida is tomatoes.
Every county in Florida produces some tomatoes for home
use and several districts during the year ship carloads to
northern and eastern markets. The production of this crop
has proven profitable to those growers who understand
marketing as well as growing.
The value of the tomatoes shipped from Florida has
exceeded $12,000,000 annually.
Celery has brought as much as $5,000,000 to Florida
growers in a single year.
Snap beans have enriched our growers an additional
$5,000,000 annually.
These figures on three vegetables indicate the im-
portance of truck crops to the State.
Irish potatoes, melons, lettuce, peppers, cucumbers,
eggplant, cabbage and other truck crops have brought ad-
ditional millions of dollars of income to the farmers of
Florida and nearly every section of the State has been
greatly benefited.
The total value of truck crops in a single year amounted
to $33,936,136 in the season of 1934-5.
The table of carlot shipments given on opposite page

produce to many waiting markets. More care in harvest-
ing and grading should materially aid in creating increased
demand for Florida grown produce. Few cars are placed
in storage and very little is canned.
The chief competition of the Florida grower is the pro-
duce grown by greenhouse producers in the North. The
production of crops in greenhouses usually is more expen-
sive than field grown products. The shipper of Florida
products, however, must deduct the cost of transportation
from his returns.
When Grown
The greatest percentage of Florida's truck crops is
raised during the cooler seasons of the year when insect
pests and plant diseases are more dormant and more easily
controlled. As the temperature rises greater vigilance is
imperative to bring the crop to a profitable income basis,
as plant diseases and insect pests will be found wherever
there is plant life.
Soil conditions, weed growth, and the root system of
the plants grown will determine the amount and times of
cultivation necessary to make a good crop, and here again
is evidence of the necessity of full knowledge of all the
operations covering the production of truck crops if a
profit is to be made.
Cover Crops
A deficiency of humus content exists in most Florida
soils with the exception of some muck soils. All soils be-
come deficient in plant food after being used and crop
rotation will not rebuild the soil to its high point of pro-
duction unless good cover crops are planted and turned
under. There are a variety of native grasses that are good
for this purpose. Cowpeas, beggarweed and crotalaria also
make good cover crops.
Any cover crop should be plowed under at least twenty
days before planting the truck crop.
A number of Florida truck crops are started in seed-
beds, and when the young plants have reached the proper
size they are transplanted to the field. Seedbeds should
be carefully planned, and in advance of the transplanting
time, to assure good, strong, healthy plants in the field.


The location, the exposure, water supply, drainage, condi-
tion of soil and freedom from insect pests and diseases are
some of the important things that must be considered be-
fore seedbeds are started. Some locations and conditions
call for special treatment and no general information can
be given except as a basis for establishing the seedbed.
The particular characteristics of the crop to be raised, the
results already achieved in the locality and a fund of infor-
mation on truck crop production are essentials to success.

romaine, cabbage, escarole, endive, cauliflower and other
fall-planted crops.
Old stable manure, or compost which is well decayed
should be thoroughly worked into the soil. A surface ap-
plication of hardwood ashes, in the proportion of a ton to


the acre, should follow the manure or compost. About a
week later the application of commercial fertilizer contain-
ing 5 per cent each of ammonia, phosphoric acid and potash
is necessary and must be worked thoroughly into the soil.
(The reader should refer to Bulletin No. 3-"Soils and
Fertilizers," issued by the Department of Agriculture, Tal-
lahassee). The bed is made smooth and the seeds are sown
several days after the commercial fertilizer has been ap-
plied. Cover the seedbeds with cloth as shown in illustra-
tions, using 4-oz. cotton sheeting. A frame of lath and
wire will support the canvas covering, giving shade during
hot weather and protection against hard rains, winds and
Winter Seedbeds
Winter seedbeds are used for eggplants, peppers, toma-
toes and other plants of a similar nature. These beds
should be 41/ or 5 feet wide and boxed in with a wall 24"
high at the back, and 10" high in front. The beds should

run east and west to obtain full benefit of the sunshine.
Winter seedbeds must be so constructed that they can be

To plant the seedbed about one-half pound of seed will
supply sufficient plants for each acre.
The more successful tomato growers apply from 1,50C
to 2,000 pounds of commercial fertilizer to the acre. The
formula most generally preferred is 4-8-8 (4% ammonia
8% available phosphoric acid, and 8% potash). The much
soils of Florida do not require as much fertilizer as the
lighter sandy soils.
All of the fertilizer is usually not applied at one time
The first application is made a week or ten days before
setting the plants. The second is applied about the time
or just before the first bloom appears. In working th(
second application of fertilizer into the soil, the cultivatior
must be shallow and care taken not to injure the roots
If the roots are injured the bloom will drop off.
Some tomato growers also apply 50 pounds of manga

fertilizer or used separately.

The early tomatoes bring the best prices. Harvestin
is an important step in the production of the crop.

Typical fruit of Glovel tomato (nal

When the fruit has reached the proper stage for ship-
aent the shading will be found to be changing from a dark
o a light green. Tomatoes should then be picked. Several
&ickings are necessary to harvest the entire crop. For
local markets the tomatoes should not be gathered so early,
iut allowed to ripen more, which will improve the flavor.
Baskets of a half bushel capacity are generally used in
harvesting. Soon after picking the fruit must be taken
o the packing house to be sorted, wrapped in paper and
)acked six baskets to the crate for shipment.
A good thing to remember about any truck crop is that
.11 of the preparatory work, labor in the field, fertilizer,

The new scarlet red variety of tomato named Glovel
vas produced co-operatively by the U. S. Department of
Agriculture and the Florida Agricultural Experiment Sta-
,ion. The Glovel is both a local market and shipping va-
It was developed from a cross between Globe and Mar-
rel, made in the Department greenhouses in Washing-
.on, D. C.
The Marvel has very strong resistance to wilt and was
developed by selection from the French variety, Merveille
les Marches. The new Glovel, therefore, has the same
parentage as the scarlet red Marglobe, but it is not a
;election from that variety.
Marvel was chosen as one of the parents because of its
vigorous vine, its abundant and continuous fruit setting
iabit and its long bearing period. In addition to being re-
sistant to fusarium wilt it also has a high resistance to
lailhead rust.
The variety, Marvel produces fruits that are smooth,
uniformly red and well flavored, but they are a little small,
somewhat flat and rather late in maturing for marketing.
Likewise they are not sufficiently solid to make a desirable
shipping product.

The variety, Globe was selected as the other parent
the reason that the fruits produced on its vines are lai
thick walled, globular and of a scarlet red. However

has caused damage to tomato crops raised for wir
The primary purpose in developing the new GlI
was to produce a scarlet red tomato that would be resist
to diseases and have good shipping quality. By combine
the disease resistant characteristics of the Marvel with
fruit qualities of the Globe, there has been produced in
Glovel a pink fruited tomato which should appeal to tl
consumers and markets who prefer the new variety.

Snap beans originated in America. They have been
lmon in this country for several centuries. Florida
is in production of market garden beans. Beans are an
,ortant although a short season crop in Florida. They
;ure from 45 to 60 days after planting. String or snap
ns are cultivated in all parts of the State. In the
then and central parts of Florida they are grown for
hi early spring and early fall crops. They will grow on
ide variety of soils, including sandy loam and muck. On
,k soil it is necessary to crop it for at least two years be-
planting beans if satisfactory growth is to be obtained.

Beans will not produce well in excessive alkaline or very
i soils. High acidity can be corrected through the ap-
ation of lime, but care should be exercised not to over-
e. Both light and heavy soils are used for bean produc-
i, but alkaline soils should not be planted to beans. Very
vy soils are not good for bean crops. If the soil is very
it apply plenty of fertilizer.
Beans thrive in sunshine and warmth. With sufficient
isture, sunshine and warmth their growth is rapid. The
Id will vary greatly, depending on many factors, but as
general rule 125 to 200 or more hampers per acre may be
Pected on good land and with favorable weather
The seedbeds should be free from clods and well pul-
ized. In the event rains cause the top soil to harden it
y be necessary to break the crust to permit the plants
break through. Beans are not gross feeders and hence
unable to obtain their share of food from spring plowed

If beans follow a sod crop the land should be plowed in
fall. It is best to follow some cultivated crop with beans.
Beans should be planted when the soil has become warm
i after danger from frost is passed as they are very
Isitive to cold weather.
Bean seed are drilled in rows about three feet apart.

Beans should have sufficient water to prevent tl
coming dark green in color.
An application of 500 to 800 pounds of 5-7-4 fi
is recommended for each acre, depending on the
content of the soil. The ammonia content of the fi
is the most important. The fertilizer should be al
week or ten days prior to planting the seed.
Beans are picked by hand when the pods have
mature size, but before they begin to ripen. As th
do not all reach picking stage at one time, two o
pickings are necessary.
Regular bean hampers are used and when filled t

Lima or butter beans are not as important to Florida
as snap or string beans. Lima beans are grown through-
out the summer and they make a good mid-year crop in
In the extreme southern part of the State they are
raised as an early spring or late fall crop.
The method of cultivation is the same as for other
beans. Where runner varieties are grown, more distance
should be given both between the rows and plants in the
row. Many growers have found it an advantage to plant
corn in the row to act as a trellis or support for the bean
There are a number of varieties of lima beans suitable
for both shipping and for home use. Among the best are
Fordhook Bush Lima and the White or Mottled Florida
butter beans.

The cultural methods for pole beans are practically the
same as for other beans, except that supports of some kind
must be put in position for the vines to climb on.
The varieties generally grown are Kentucky Wonder
and Florida Pole.

give very satisfactory results.
Cucumbers are invariably planted in the fiel(

About half of the fertilizer is applied ten days

eks before planting, and the remainder a short time be-
re the first blooms appear. The second application
would be just ahead of cultivation so that the one opera-
n will cultivate the crop and at the same time work the
'tilizer into the soil.
The crop is often helped by a side dressing of nitrate
soda or sulphate of ammonia, at the rate of 150 to 200
funds to the acre. If the fertilizer is not applied when
- foliage is dry, there is danger of burning the plants.
The crop is ready for picking when the fruit has at-
ned a size from five to eight inches in length, depending
its color. Cucumbers should be straight and of uniform
meter and of a dark green color. When a yellow color-
r appears it indicates over-ripeness. Such fruit has no
irket value.
Several pickings are necessary for the cucumbers will
t all mature at the same time. The field should be gone
er carefully two or three times a week. The harvesting
ison may cover a period of two or three weeks.
Use field crates to gather the crop. These are taken

Eggplant such as these are generally profitable. (


The eggplant is a native of the Old World. India is
probably its home. The Chinese and Arabs grew eggplants
in the ninth century. The early types had small egg-shaped
fruits which accounts for its name. Its botanical name is
Solanum melongena and it is closely related to the tomato,
potato, pepper and other solanaceous plants. Two of our
serious weed pests, the horse nettle and the nightshade,
belong to the genus. The eggplant will thrive under rela-
tively high temperature conditions.
Fertility, moisture supply and good drainage are neces-
sary to its successful propagation. Wherever soil is found
in Florida that will grow vegetables, eggplants can be pro,;
duced. In South Florida they are produced as a winter
crop; in the other sections of the State they are raised as
late fall or early spring crops.
Sandy loam soil supplied with vegetable matter, plus a
constant supply of moisture until the plants have become
firmly rooted is necessary to produce healthy plants.
Growing the Plants
The growing of the plants is evry important. Stunted
or injured plants will not develop into high yielding plants
and possibly will result in a crop failure. Eggplant seeds
should be sown in rich, mellow soil.
Eggplants are more sensitive to weather conditions
than any other vegetable planted in the same manner.
Local weather conditions should govern the time for set-
ting the plants in the field. Planting should be delayed
until all danger from frost has passed.
The production of eggplants is similar to that for toma-
toes, but they are not so easily raised and require more
The seedbed should receive the best of attention as egg-
plants are subject to more diseases than tomatoes. If in
the beginning of the crop this important phase is over-
looked the crop is likely to be a failure. Plant the seed-
beds four weeks before transplanting to the field.
In transplanting from the seedbed the young plants
must be carefully handled to prevent injury.

The plants mature in about four months after tra:
planting. Six ounces of seed in the seedbed should prodi
3,000 plants, which is sufficient for an acre. Place the plal
at distances of three feet in rows five feet apart. Again I

Commercial fertilizer and manure can be used w
profit in eggplant production. On fertile soils apply
tons of well rotted manure to the acre. It should be v

The fertilizer is divided and one-half applied two we(
before the plants are set and the remainder when the plal
are 10 to 12 inches high; 1,200 to 4,000 pounds of 5-,
fertilizer is used to each acre, depending on the fertil
of the soil.
The harvesting may be started any time after the fr

Factors Governing the Field Production of Lettuce
Temperatures, moisture, and soil are important con-
tributing factors in the successful production of lettuce in
Florida. Lettuce requires a relatively low average temper-
ature, especially after the heads begin to form. Any good
trucking soil will grow lettuce, provided moisture and
plant-food conditions are suitable. Soil requirements con-
sist of adaptability to intensive cultivation, capacity to
retain moisture, and an abundance of plant food.

A large proportion of the commercial crop of head let-
tuce is started in beds and transplanted to the field. The
usual custom is to prepare seedbeds either in hotbeds, in
coldframes, or in the open ground, fertilize the soil of the
seed bed somewhat highly, about 4 pounds of fertilizer
per 100 square feet, and sow the seed thinly so as to produce
strong, healthy plants. One-half pound of good seed
planted in a special seedbed will produce enough plants
with which to set an acre of lettuce. Approximately 50
coldframe sash 3 by 6 feet will be required for growing
these plants. Where the beds are in the open and not cov-
ered with sash, a bed 100 feet long and 12 feet wide is
recommended. Great care must be taken in the watering
and ventilation of the plant beds in order to avoid losses
by damping off. This disease seldom gives trouble in the
open beds, except during seasons of excessive rainfall ac-
companied by warm weather.
Lettuce growers sometimes start the plants by drilling
the seed in rows in the open ground, using an ordinary
garden seed drill and spacing the rows 10 or 12 inches
apart. Where the seed is sown in this manner the plants
will be ready for setting in the field in from 30 to 40 days.
Lettuce seed retains its viability for several years if
stored under proper conditions, but in order to obtain
vigorous plants it is recommended that seed not more than
two years old be planted. Strictly fresh lettuce seed, that
is, seed that is planted the same season that it is grown,
is likely to give a poor germination, and for that reason it
is desirable to plant seed grown the previous season.


Lettuce is transplanted when four leaves have formed.
A rich, moist, compact, sandy loam soil that can be thor-
oughly irrigated and well drained produces the best crops.
The soil should be well supplied with humus, and kept
moist constantly but with good drainage. It may be neces-
sary to irrigate. Care must be exercised as the crop is
easily ruined by too much water.
Crop rotation in lettuce growing has proved to be of
value, both in the control of diseases and in the mainte-
nance of soil fertility and physical conditions through the
use of green manures.
Hand cultivation is generally employed in the growing
of lettuce, but in a few sections the rows are spaced so
as to permit of horse cultivation. Small garden tractors
are now being employed extensively, both for drawing the
gangs of seed drills used in sowing the lettuce and for its
cultivation. The object of cultivation in lettuce growing is
primarily the control of weeds, as the soil is thoroughly
prepared before planting. Where the plants have been
transplanted in check rows they can be cultivated in both
directions until the heads begin to form. This will elimi-
nate a large part of the hand work of hoeing and weeding.
Manure containing a large proportion of undecayed
straw or other coarse bedding should not be applied, be-
cause the decay of coarse straw or other woody materials
results in the temporary depletion of the available nitrogen
in the soil. This is likewise true of soil improving crops
used as substitutes for manure, and these should be turned
under while green and in condition to decay quickly. Thor-
ough disking of the material in advance of plowing will
greatly facilitate the disintegration of the organic matter.
The manure for use on lettuce land should be composted
in a compact pile for at least three months and preferably
six months in advance of being spread on the land. During
this period the leachings from the pile should be collected
in a pit and pumped over the pile of manure from time to
time. If the manure is excessively dry at the time it is
piled for composting, enough water should be added to
cause it to decay rapidly. The manure is usually spread
broadcast over the land with a spreader or by hand at the
rate of 20 to 40 tons to the acre and thoroughly disked

into tne son. une sucn application every tree years inter-
spersed with at least two soil-building crops will usually
be sufficient to maintain the organic matter in the soil.
A liberal supply of plant food will produce tender let-
tuce. If the soil is deficient then liberal applications of
5-5-5 fertilizer is added. The quantity ranging from 1,500
to 2,500 pounds to the acre is divided and half of the
amount applied two weeks before the plants are set and
the remainder two weeks after setting the plants. Each
acre will have from 45,000 to 50,000 plants to feed and be
kept in good condition.
Lettuce requires a constant fairly high moisture con-
tent in the soil. Excessive rainfall or irrigation will seri-
ously damage the crop. Lack of moisture in the soil will
stunt the growth and produce poor heads. A moisture con-
dition in the soil which is just a little greater than that
required for good transplanting is satisfactory or just
about as great as is permissible for cultivation.
Lettuce intended for long-distance shipment is packed
without washing. Eastern-grown outdoor lettuce which is
shipped in carloads is packed in the field.
Under favorable conditions the greater part of a crop

of lettuce can be harvested at one cutting, but it is often
necessary to go over the field three or four times, each time
cutting only the heads that are matured. The different
cuttings, however, may usually be made at intervals of
two or three days. Immature heads are spongy and do not
hold up well during transit and marketing. It frequently
happens that head lettuce matures and is at its best before
the heads are solid. The solidity of the heads at maturity
also depends to some degree upon variety.
The common practice of lettuce growers is to distribute
the crates or hampers along one side of the field and begin
cutting at that point. Cutting is usually done as early in
the morning as possible. Heads that have been frosted
in the field should never be handled while in that condition.
The first 10 or 12 rows of lettuce are cut and packed, and
the containers are loaded upon the wagons or trucks for
hauling to the car. Another section of 7 to 12 rows is

g and packing of the lettuce, the crates or h,

loaded into the cars. Lettuce should be hauled to the
packing shed promptly after it is cut, and there should
be no delay in having it crated and placed under ice. Rough
handling of the crates after they are packed should also be
strictly avoided.
Lettuce is ready for harvesting within 70 to 80 days
after transplanting when the heads have become fairly
solid. It is packed in standard crates 71/2"x18"x22" or in
standard hampers. A carload contains from 350 to 400
crates or hampers.

Insect Enemies-Cutworms*
The lettuce plant is comparatively free from insect at-
tack. Cutworms are particularly destructive to the seedling
crop. Some winter in the soil in the immature worm stage,
and as soon as the weather becomes favorable in the spring
they attack the early-planted crop. Later in the season the
crop may be damaged by cutworms that pass the winter in
the egg stage. The crop is also subject to attack from
worms that hatch from eggs laid by the moth in early
spring and through the season. Cutworms damage the
crop by cutting the plants off near the ground. They feed
for the most part at night, spending the day inactive just
below the surface of the soil.
Cutworms may be controlled by the timely use of a
poisoned-bran bait, as shown in the directions that follow.

(1) Thoroughly dry mix the poison with the bran. This is im-
portant, as each particle of bran must carry a little poison in order
to get a good kill. When making small quantities mix the bait in a
bucket with a paddle, adding the poison slowly and stirring the bran
at the same time. A more effective way is to mix the poison and
the bran with the hands, but as soluble arsenic to a slight extent is
absorbed through the pores of the skin, there may be some objection
to this method. If the hands have any cuts, scratches, or other

;ies, the poison can be mixed with the bran on some flat, smooth
surface, using a shovel and rake in much the same way as m
mixing concrete.
(2) Mix the sirup with the water.
(3) Add the water and sirup solution to the mixture of bran and
poison, stirring slowly all the time. Large quantities of water added
it one time will wash the poison from the bran, resulting in an
uneven mixture.
Caution.-Add only enough liquid to make a crumbly mass. It is
a good plan to set aside a little of the mixture of dry bran and arse-
lic so that if too much water has been used this reserve can be
idded to bring the mixture to the proper consistency. Large quanti-
;ies can be made up in galvanized-iron or wooden washtubs, and
small quantities in buckets or similar containers.
How and when to use the bait.-Either broadcast the poisoned
bait or sow it by hand along the rows or about the base of the plants

ate in the evening so that it will not dry out to any great extent be-
.ore the worms become active. Because cutworms overwinter in the
around, it is a good plan to broadcast the poisoned bait over the
cultivated areas a few days before the crop comes up or is set in the
field Where plants are to be transplanted to the field, this method
s particularly valuable. If hills are made for melons or tomatoes,
ipply the bait directly to the hills a few days before the crop is set
n the field. Such applications will rid the field of many of the
vorms before the crop is subject to attack.
Quantity of bait to use: 10 to 15 pounds of the wet bait is suffi-
cient for one application per acre. Where the bait is applied di-

rectly to the rows or hills, a smaller quantity will suffice. It may
require two or three applications at intervals of two days to rid the
field of the pests.
Plant Lice and Other Pests
Plant lice or aphids sometimes attack the lettuce crop.
These pests can best be controlled, especially on the young
crop, by the use of nicotine dust containing 2 per cent of
nicotine. Apply the dust when the air temperature is above
70 F. and when the foliage of the plants is dry, and when
there is little air movement. The dust should be applied
to the under side of the leaves, where the insects feed.
Nicotine dust should be applied to the crop not later than
10 days before harvest.

casionally become troublesome. Up to the present time no

entirely satisfactory method has been developed for the
control of these pests, although arsenical treatments will
control the lettuce looper, such treatments are not recom-
mended on crops with edible foliage, except when the crop
is in the earliest stages of development.
Tipburn is a nonparasitic disease, occurring primarily
during warm weather, and particularly when warm bright
days follow periods of foggy or rainy weather. Although

resulting irom cnimalic concutlons, 1Lne trouDie is mucn
reduced by good cultural methods and care in fertilizing
ind irrigating. Lettuce varieties differ greatly in suscept-
ibility to tipburn.
Simple tipburn is manifested by brown dead areas
around the margins of the leaves without decay. Decay
Fungi and bacteria, however, often gain a foothold in these
lead margins, causing soft rot both in the field and in
shipment and markets. Shippers and dealers frequently
refer to this soft rot as slime. Soft rot may sometimes
effect heads that are free from tipburn.
Downy mildew also attacks wild lettuce, and this weed
should be eradicated from the vicinity of lettuce fields and
greenhouses. Crop rotation is advisable. Applications of
Bordeaux mixture to the small plants hold the diseases in
,heck while the plants are young.
Lettuce drop is caused by a fungus which usually at-
;acks the stem near the surface of the soil, causing a soft
eatery rot. This rot soon involves the entire stem and
eaf bases and results in the collapse of the plant. The
casual fungus may live in the soil for at least two years.
Crops recommended for rotation with lettuce are sweet
corn, tomatoes, potatoes, cucumbers, radishes, beets, spin-
ich, and onions. Celery and cabbage should not be grown
n the rotation as they are quite susceptible to the disease.
Damping off of small lettuce plants, which occurs par-
;icularly in seed beds, is caused by various fungi. Keep-
ng the surface of the soil and the plants as dry as possible
s of primary importance in preventing the trouble. Means
)f accomplishing this are the selection of a reasonable light
soil of a type that dries readily after watering, the sparing
ise of water, the avoiding of crowding of the plants. New
;oil that has been in grass or general farm crops for sev-
eral years usually gives less trouble than soil that has
grown vegetables or flowers for some time.
Some other diseases are bottom rot, anthracnose, bac-
;erial wilt, mosaic, and yellows.

le pea is a cool-weather plant. Not only will the seeds
inate and make vigorous growth at lower tempera-
with many vegetable crops, but cool weather is
sary for obtaining good yields and high quality. High
erature checks the growth of the plants and causes
to flower and form pods before the plants have at-
d sufficient size to bear a good crop, while cool

no cultural attention after the seed is sown. The opera-
tions before planting will influence, in part, the water con-
tent of the soil for the season of pea growing. The pre-
liminary preparation, furthermore, will control the devel-
opment of the root system and influence the extent of
weed infestation.
The rows are generally laid out about four feet apart
and the seed sown fairly thick. About two bushels of seed
are required to the acre. Plant the seeds deep if the soil

Insect Pests
The pea crop is subject to the attacks of certain insect
pests. Among the insects that may cause damage are the
pea aphid and the pea weevil. The aphid is perhaps the
only insect that makes serious inroads on the growing
of green peas. The aphid can be controlled in part by



crop rotations. The presence of the weevil should be noted
at the time of planting. Weevil-infested seed may give a
germination as low as 30 per cent.
The pea plant is subject to two groups of plant diseases,
both of which vary in prevalence in different localities
from season to season. The more conspicuous and better-
known group consists of those which attack parts of the
plant above ground. Among these are the so-called pea
blight, leaf and pod spot, and mildew. The less conspicuous
and more important group of diseases cause decay of the
plant below ground, resulting in reduced growth and in
extreme cases the wilting of the entire plant. Against
both these groups of diseases only preventive measures
are practicable.
Crop Rotation
Nearly all of the foliage diseases are carried over from
year to year on dead straw and debris of the pea plant.

Place in a dish, season with salt and pepper, pour over the okra a
tablespoonful of tarragon vinegar, and set to cool. Serve as a
salad with roast meats, etc.

Place a thin layer of rice in a baking dish, add a layer of sliced

the rows. Squash plants grow close to the ground and
obtain their food from the surface of the soil. In culti-
vating care must be taken not to bruise the plants.
Planting should be delayed until the soil has warmed
up and in good condition for germination of the seed. The
seed germinates best at a relatively high temperature and
is likely to decay if planted in a cold, wet soil.
The bush and small vine varieties may be planted in
hills as close as 4 by 4 feet, but the varieties having long
running vines should be spaced 8 to 12 feet apart each
way, depending on the growth habit of the variety and the
fertility of the soil.
If manure or compost are not available, 800 to 1,200
pounds of 4-8-4 commercial fertilizer should be applied to
each acre. The entire amount can be used before planting.
If the land is thin, sandy loam it is best to make two
applications, one-half before planting and the other after


the plants are about a month old. If manure or compost
is available the amount of fertilizer can be reduced to 600
to 1,000 pounds to the acre. Squash plants need a supply
of available ammonia.

Squashes are shipped in standard cabbage crates or
bushel hampers. When shipped early the grower gener-
ally realizes good profit on the basis of cost of production.
With ordinary care in harvesting there should be no diffi-
culty from rotting in transit. Ripe squash may be gath-

vW .L"
So far as we know, asparagus was first discovered in
the north temperate regions of Europe, where there is a
continuance of cold weather for several months. Cold
weather prevents budding during these cold periods and
the growth is practically dormant. Following these dor-
mant periods the plants begin their normal growth and
the green tips will grow rapidly. Soon after, cutting of
the tips begins.
In South Carolina, where considerable asparagus is
grown profitably, the temperature during November to
February is sufficient to bring about a dormant condition
in growth. Like most natural desert areas, the tempera-
ture in the Imperial Valley Desert, California, (where as-
paragus is grown) has continuous cold nights which check
asparagus growth during one or two months of the year.
The average Florida temperature is mild with occa-
sional freezing weather lasting but a few days. Frost will
kill the asparagus tops, but warm days induce new growth.
In the course of a year the tops may be killed two or three
times. Every time new shoots develop, the reserve plant
food is depleted and the new crowns which are formed
lack strength and vigor.
In the northern and northwestern parts of Florida some
truck raisers have been able to maintain asparagus plants
in fair production for three or four years. This section
of Florida seems to offer encouragement to asparagus
raisers, but care must be taken in selection of soil, its
moisture content and fertility.
Planting In the Everglades
Several years ago 275 acres in the vicinity of Canal
Point was planted in the muck soil of the Everglades. In
May, 1928, approximately 40 acres were planted to two-
year-old asparagus roots shipped from the Imperial Valley
of California. Prior to September of the same year these
plants had made a very satisfactory growth. New crowns
had formed within four months from the time of planting.
Growers familiar with asparagus production in other parts
of the United States stated that they never seen such re-
markable plant growth. Indications for cutting a profit-
able crop during January to March of 1929 were excep-
tionally good, but the flood waters from Lake Okeechobee
during that year ruined most of the crop. Credit must be
given those growers who are persistently attempting to
overcome these difficulties.
Another tract of 75 acres was planted in the same area

At present the trade centers of Florida seem to offer
very good markets for asparagus. Since no other aspara-
gus areas can produce a crop during the winter months,
there should be no marketing problem for several years.

crop: First, the striped cucumber beetle; second, a "six-

asparagus fields are kept clean and the grass and weeds
are allowed to stand in the asparagus rows, then some
danger results, as the insects are forced to come to the
asparagus. If the reverse conditions obtain, the insects
seem to prefer the native growth on the ditches, and prac-
tically leave asparagus unmolested.
Only the better varieties of the rust-resistant types
should be planted. Mary Washington and Martha Wash-
ington are popular with asparagus growers.


Escarole and Endive
Escarole or Broad Leafed Batavian Endive belongs tc
that group of plants known as the Composites, which iE
one of the largest families in the plant kingdom. Escarole
is a variety of chicory, endive has been cultivated in the
United States since 1806. Only five of the Composites
however, are known to have any appreciable economic
value as garden crops and are of importance in the order
Globe Artichoke;
Escarole or Endive;
Salsify or Oyster Plant.
Escarole is used principally as salad. In its unbleached
state it is also eaten as "greens." Florida produces over
$100,000 worth of escarole annually. Only within com-
paratively recent years has escarole become generally
known in American home gardens. It is gradually gain-
ing favor. When good lettuce is not obtainable escarole
makes a very good substitute. From mid-summer through
early fall and winter it will be found in our markets. Dur-
ing the hot summer months and early fall, solid head let-
tuce is difficult to purchase in some markets and un-
blanched escarole, having a better flavor meets with ready
acceptance among many consumers.
Poor land that is deficient in humus or that is dry and
exposed is not suitable for the cultivation of this crop. Any
soil that has ordinary fertility or that has been enriched
through the application of manure or other fertilizer will
produce escarole. A warm soil to which has been added
plenty of manure raises the best crop.
If the seed is sown in the field, the first planting may
be made in June and followed by other plantings through
August. The rows should be about twelve to twenty
inches apart. While the plants are small they are thinned,
leaving a foot of space between the plants in the rows.
The seed may be sown in seedbeds such as are used for
lettuce, and the young seedlings transplanted to the field.
Seedbeds are preferable when the ground is very dry as
this method of planting assures stronger plants. It is best
to transplant after a rain. if nnqihblp whilp th.e nil is

along each side of the rows. The tops of the boards are
brought together to keep out the light. The method of
blanching is similar to that used for celery except no light
is admitted at the top. The hearts of the plants are fully
covered. About three weeks are necessary to bleach the
plants to a delicate white or creamy color. The heart and
inner leaves will be crisp, tender and have a pleasant flavor.
To overcome the bitter flavor the leaves and hearts of
the plants must be well blanched.
Insect Enemies and Diseases
The diseases and insect enemies that attack spinach
and lettuce sometimes must be guarded against in the pro-
duction of this crop. The recommendations for their con-
trol is the same as for these crops.
The varieties preferred by most growers are Batavian,
French Moss Curled and Imperial.
The Green Curled variety has been popular with grow-
ers for many years. It has narrow, curled leaves. When
well blanched it is a very attractive vegetable. Broad
Leaf has wider and plain leaves and is a variety that is
gaining in popularity.
The curled varieties of Escarole or Endive are both
ornamental and attractive plants in the home garden.

The remainder of those given in the above graph are so-called

Best root development is obtained in relatively cool
soils. The young plants will withstand a temperature that
is several degrees below freezing.
During early growth it is highly essential that ample
soil moisture be maintained near the surface. New roots

will not develop in dry soil. Should the growth be sus-
pended the outer scales of the bulb mature, and when
growth is resumed the inner scales take on additional
growth, which results in splitting of the bulbs.
Onions grow best when there is plenty of daylight, or
during long days. Varieties differ in this respect but they
seem to do best when there are about 15 hours of daylight.
Possibly this explains why onions do not "bottom" early
irrespective of the time of planting. Plantings made in
January are less subject to weed growth, insect pests and
plant diseases.
The bulk of the crop in Florida is planted directly in
the field. The soil must be in good tilth and thoroughly
pulverized. From 31/2 to 5 pounds of seed are required to
plant an acre. The seed is generally sown to a depth of
1/ to 1 inch although in muck soils the seed is often planted
2 inches deep.
The use of a seed drill is necessary for uniform dis-
tribution. The rows range from 14 to 24 inches apart
and are parallel to facilitate cultivating. Onion seed ger-
minate best when the soil temperature is about 65 degrees.
The root system of onions will not permit deep cultiva-
tion. If the field has been properly prepared in advance
of sowing the seed a minimum amount of cultivating will
be necessary. Hand tools are used almost exclusively in
the production of this crop as the plants in their early

die the rows. With both types the double knife attachment
is used. This cuts a swath just beneath the soil surface
on both sides of the row. This kind of cultivating kills
small weeds and stirs the surface of the soil without cover-
ing the young plants. Weed growth, rainfall and other
conditions will determine the frequency of cultivating but
usually the plants are cultivated every week to ten days.
For the last cultivation some growers substitute a triple
set of shovels. The shovels turn a small amount of soil
against the rows, affording some protection to exposed
bulbs, giving them a better color. If the shovels are run
deep enough, many roots may be severed, thus hastening
maturity. This may be an important factor in Florida
under certain climatic or market conditions.

Irrigation and Drainage
The control of soil moisture is a prime necessity in
onion culture. Sub-irrigation or overhead systems are
quite satisfactory. Tiling of the land may serve a dual
purpose-drainage and irrigation-if properly done. While
there are no records available in Florida, irrigation plants
elsewhere have frequently more than doubled the yield. A
small area properly handled will be more productive, pro-
portionately, than larger areas carelessly managed.

The economical way to thin the rows is to bunch the
onions pulled and sell them on the local market. Thinning

most crops, especially in the sandy soils of Florida, barn-
yard manure, chicken manure and most litter should be
conserved and made into compost. Onions thrive under
large quantities of organic matter. Organic matter not
only provides plant food but improves the physical condi-
tions of the soil, giving it greater water-holding capacity.
In many muck areas where onions are grown extensively,
it is not an unusual practice for the growers to give the land
a liberal application of barnyard manure. The beneficial
action of the bacteria is worth the cost. Usually it is good
practice to apply the manure to the crop grown ahead of
onions, unless it is well composted. Weed seed and a ten-
dency to keep the ground too open are the chief objections
to applying manure to onions.
Cover Crops
Barnyard manure may not be available and cover crops
must then take its place. Most grasses, except nut and
Bermuda will add humus to the soil and should be allowed
to grow for the purpose of later turning under. Crotalaria,
a leguminous, rank-growing annual that is resistant to
nematode infection, is the most promising cover crop for
Florida truckers. Other good legumes are velvet beans,
cow peas and beggarweed.
Transplanted Onions
There are advantages in starting onions in a good seed-
bed. The growing can be better controlled, the bulbs will
be more uniform and the yield per acre will probably be

Recent studies have shown that Prizetaker and Yellow
Globe Danvers are not adapted to the short days in the

Australian Brown has many desirable qualities. It is
a very good keeper. It requires a longer time to mature,
however, than many other varieties and this is objection-
able because of the difficulty of curing during June.
White Portugal is grown as an early-market onion and
for sets. They do not keep as well as most of the yellow
varieties such as the Yellow Globe Danvers.
Seed Selection
Carefully conducted strain and variety tests should be
used as a basis for selection and breeding. Some of the
Spanish varieties are preferred for this purpose.
Good seed is the first and most important factor in
successful onion production. Onion seed deteriorates rap-
idly in this climate. The following comparisons show how
onion seed in Connecticut lost vitality with age. The seed
were produced in California:
Number Percentage
of That
Samples Germinated
Seed less than 1 year old ........... 400 88.18
Seed between 1 and 2 years old...... 220 77.46
Seed between 2 and 3 years old...... 2,023 57.34
Seed between 3 and 4 years old --.... 1 10.00
Seedmen claim that in a single year onion seed loses
practically all its ability to germinate.
Uniformity in size, shape, color and time of maturity
of bulbs is essential. Methods usually employed in grow-
ing onion seed for the trade are not all that could be de-
sired. As a consequence there are usually wide variations
in a field grown from such seed from a single source. For
instance, the Ohio Experiment Station in an onion variety
test found one strain, supposedly a Globe variety, which
had but 65.8 per cent Globes. It showed 2 per cent scal-
lion, 9 per cent flat, 7 per cent off color and 26.1 per cent
bottle-neck. This was not the poorest lot tested. Off-
color is a serious trouble, since a red or yellow onion in a
pile of white ones is very conspicuous. Only 8 of the 66
strains tested passed a perfect record as to color.
Plant Diseases-Mildew
This is one of the most destructive diseases in Florida.
It may be recognized by the furry, violet-colored growth


upon the leaves. It is especially conspicuous when the
leaves are wet with dew. Within a few days large areas
become pale green and then yellow. The seed stalk as
well as the leaves may be affected. They collapse and die.
The disease is caused by a fungus called "Pernospora
schleideniana" which works very rapidly in high tempera-
tures in the presence of dews, rains, cloudy and foggy
weather. It is often most destructive to a seed crop.
Control: Good aeration of the field will do much to-
ward controlling mildew. This may be facilitated by run-
ning the rows in the same direction as the prevailing winds
and by avoiding wind breaks or other obstructions to the
wind. If the rows are planted somewhat wider apart, bet-
ter aeration is possible.
Onions should not be planted on the same piece of land
oftener than once in three or four years. The resting
spores of the fungus are carried on diseased leaves. It is
imperative that these be kept away from diseasefree fields.
Spraying has been employed to some extent. A 4-4-50
bordeaux mixture, with 3 pounds of resin fish-oil soap to
each 50 gallons, is quite effective. Several applications
may be required to protect the young foliage.

The head is browned and spotted and is unmarketable when

is not sufficiently injurious to justify control measures
other than seedbed and field rotation. At time of packing,
