SEED BEDl
Ini South Florida, Ipapaya seed may lie sown at any timel dur-
ing tlhe vyiar. The. seed bed should he thoroughly Il-repared by
inlorl)poraiiilla a; ( g(oodly lluaintity of humolls, and the soil should
he kept in a friable. mellow condiition. Flats or boxes may he
used. conltaiingin about four inches of soil underlaid with some
charcoal. It is i-'eiierally advisable to plant the seeds in rows
fouI inchles apart. leavi'lln about tile sanile dlistanice between the
single seeds il tihe rows. The seed 111.st then lite overed with
porous soil not more than one-hialf inch deep. l'The seed bed
must be kept moist biut not wet. and it is intessary to prIoteet
it d(uiniig tIle ii hlit against Ipossible frost.
The seed will begin to sprout about two weeks after they
are planted. When tilte ouning plants have attained a height
of about foiur inclies, t(hey are ready to be transplanted to
flower pots or o(li'er su iljlt]e conltaillers.

PLANTING ;

When tlie young papayas are about 8 inches hiigh, they should
be transplaintedl to thte open field. If tiln cans are used, it is
lot l'eessarv to remltove t heil ti le till will sooni rust whlie ill
contact will tlhe soil and the roots can then easily penetrate
the walls.
Whlien plaintig on sand s soil, tihe holes should be made two
feet ill diameter and one foot deep. Then il is desirable to
fill these holes with well rotted compost aind allow them to
settle for several days. The papayas may be planted 6 to 10
feet apart. The vyounig plants may Ite set somliewhat deeper
in the soil than they stood in tIlhe seed bed. They a're very
susceptible to standing water and rot off at Ile base if water
collects around the 1111trn11k.
After th le plants have been removed to the open field, they
slioihl le prolected against the rays of tIle sun. for which
purpose oldhi ball happier may be used.
Wlihile it is advisable to replat thlie voiunig seedlini'-s before
thlie are more tlian one foot lhighi. even large plants from five
to six feet high imiav he t'ranspllalted if they are takelin up with
a lar'._,e ball of earth and if ;all large leaves are removed.
Alter tran)splailtig, the younil plants should lhe watered
r'equ'iieitly until thwey *i vhive becol.me well established. Without
an adl.|iial supply of moisture. the plants will and drop thll
leaves. W while the pllailts are y'ouln g, a muilchli colsistin' of le

cheek evaporation, but also creates conditions favorable for
nitrification. Later when the leaves afford sufficient shade, the
mulch may be disposed of and the remnants incorporated into
the soil. After the papayas have rooted well. few difficulties
will e encountered, and rowh will ecouteed, d growbe so rapid that one will
be able to note its progress almost daily.
In frost-protected locations, the papaya seed are sometimes
dropped direct in the places where the plants are desired to
grow. If three or four seeds are placed to a hill, the weaker
plants and males may he eliminated later, but plants grown
under this system are often spindly and not so stocky.

IN THE PAPAYA ORC(IIARI)

The first blossoms appear about one month after transplant-
ing, and flowering and fruiting go on almost continuously. If
properly cared for, the papaya will yield considerable fruit
during the first year. The size of the fruit varies according
to the variety. Usually a plant produces fruit of the same
form. but the size is usually smaller as the trees get older.
Some fruits are not Imuch larger than a pear, while others may
reach weights of 15 or 20 pounds. They vary in shape from
spherical to cylindrical. The most desirable size, however, is
fruit weighing from two and a half to four pounds.
Tle papaya fruit has a thin skin. The flesh, which is white
Ibfore maturity, later turning to a deep orange in color, is
from one to three inches in thickness. Inside of this is a cavity
which, attached to its wall, contains numerous grayish-blaek
wrinkled seeds tlhe size of a small pea.
The papaya plant characteristically consists of a single trunk,
bearing dark green, deeply lobed leaves, sometimes two feet
across and supported by hollow petioles several feet long. The
leaves are so arranged that they appear like an umbrella
shading tlie fruit, which is closely clustered near the top. The
leaves, as they grow older, turn yellow and drop to thle ground,
leaving conspi(uious scars on the trunk. If developed undis-
turbed. the trunk usually has no lateral branches. When a
plant has grown so tall that it becomes inconvenient to gather
the fruit, the trunk may be cut a few feet above the ground.
and a nunt)er of sprouts will later bear fruit like the mother
plant.
A slight frost will usually kill the papaya down to the root.
If the lower part of the trunk is banked with soil, and the
upper end c(ut off in time to prevent further decay, the root
may develop several sprouts. Wind storms also may cause

heavy losses in papaya plantings, which makes it desirable lo
have wind breaks on the exposed sides of the orchard.
The papaya plant is comparatively short lived. In some see-
tions of Florida the plants are expected to produce only one
crop of fruit. while in other sections thireeo five years is
about tie life of a plant. In sections where only one crop of
fruit is expected front each plant, the plants are inter-planted
each year. In other sections where the plants are expected to
live longer, inter-plantings are made every three to five years.
In this way the plantings are maintained from year to year.

I'ESTS AND I)ISEASES

There are two pests that threaten the papaya: i. e., the
papaya fruit fly and the papaya leaf blight or leaf-spot, a
fungus disease.
The female of the papaya fruit fly inserts her eggs into tlie
youngii inniature fruits by means of a long ovipositor. The
young larvae first feed on the seeds, but later on work into
the flesh, causing the dropping of the fruit or making it unfit
for human consumption. It is, therefore, advisable to prolpa
gate only varieties having very thick flesh so that tlihe eggs
cannot be deposited in tlie seed cavity.
The papaya leaf-spot. although previously observed in the
West Indies, has been reported in Florida. This fungus dis-
ease attacks tlie foliage, forming oil tie under-surface of the
infected leaf, black pustular spots which are slightly raised
above the leaf tissues. Tlie infested areas appear on the upper
side of the leaves as brown distinctly outlined spots. In the
black masses on the uider-surface of the leaf are found the
spores of the fungus, which. carried by wind or insects, spread
tlie disease. A severe attack may cause complete defoliation
and death of the plant.
If discovered in time. tile leaf-spot may lie controlled by
thoroughly spraying with i-8-50 Bordeaux mixture. Both
upper and under side of the leaves should be thorouglghly cov-
'red with tlhe spray in order to kill all spores Iproduced and
protect tlhe new leaves against infection. It will be necessary
to repeat the spraying three or four times at intervals of about
ten days. It is also advisable to remove and ldstroy all severe-
ly infected leaves both on the plaits and on the ground, and
the remaining foliage must he sprayed at weekly intervals
until tle disease has disappeared. In case of a severe attack
on young plants, it will he more economical to remove them
and plant new ones.

D.EI,\RAI'ENT OF AGRICU'LLTURE


Nelmatodes (root-knot) may cause some loss in young plants,
but if the seedlings are grown in seed beds free of nematodes,
the damage from this cause will be slight.
There are few scale insects found on papayas that are
troublesome to the orchardist.

YIEIU) ANI) MARKET

At present the demand for papayas is much greater than
tle supply and the retail price ranges from 10 to 12 cents per
pound. However. as more of this fruit goes on the market, the
price is likely to be reduced, and in the future it is possible
that the price may he reduced one half, or even more. of the
above prices.
Papayas respond very quickly to good treatment. During
18 months an exceptionally good healthy tree may yield as
much as 300 pounds of fruit. An average yield for an orchard
is usually between 50 and 100 pounds of fruit per plant. Most
varieties turn golden yellow during ripening, while others re-
main green. If it is desired to ship them, they should be
picked before fully ripe, and carefully packed in excelsior.
The conlmercial possibilities of papaya culture are somewhat
limited because it is not safe to ship the fruit a great dis-
lance without icing it properly. However, oi several occa-
sions, fruit has been shipped as far as northern ('anada and
Europe, the shipments arriving in good condition and selling
at a handsome price.
The ripe papaya endures cold storage exceptionally well.
Even after two months in cold storage, the characteristic flavor
will have been retained almost perfectly. Frosted fruit, how-
ever, is not palatable, being tasteless and insipid.
It is not to be expected that papayas will be an economic
factor of prime importance, yet with improved transportation
and with wider familiarity with the merits of this delicious
fruit, the northern markets should offer good opportunities.
At least every home garden and grove in South Florida should
possess a few papaya plants, picturesque as well as useful.

PAPAIN
It is doubtful if Vlorida will ever be able to compete with
foreign markets in manufacturing papain, yet it may be worth-
while trying. To such growers as would be interested in rais-
ing papayas for papain extraction, the following -remarks by
V. A. Beckly. printed in the Journal of the Department of
Agriculture. UInion of South Africa, may be helpful:





P AP~AYA. ('LTIATE IN FLORIDiA


"It is well known that the juice of the papayas will remler
tou,'h nelat more tender. This is due to a ferment (papain)
which possesses the power of dlig'esting protein materials such
as menat e.L'L' white, the vuNrd oft milk, etc. Its action is similar
to the t\wo well-known body fevrmenits. pepsin and trypsin.
()n account of its efficiency being' greater than llhat of pepsin.
it is largely replacing that substance as a dir '.

PAPAYA (TIATRE IN P'LORIDA






D)EPA RTM1\ENT OF~ AGR ICULTI'RE


The papaya is a very common fruit itn Hawaii and is served
in many different ways on the island. The following quota-
tion. taken from Bulletin No. 32 of tlie Hawaii Agricultural
Experiment Station. "The Papaya in Hawaii," will give the
reader an idea of tie food value of papaya, and some of the
methods of preparing the fruit for table use in Hawaii should
he of interest to people in Florida.

THE PAPAYA AS A FOOD

Perhaps lthe mIost frequielit use of the papaya is as food, al-
though almost all parts of the plant are utilized in some way.
The general composition of the papaya fruit is shown by the
following analysis:*
Percent
Water 90.75
Protein .80
Fat .10
Fiber 1.09
Nitrogen-free extract 6.32
Ash ....94
Reference lias been made above to tlhe nearly universal use
of the ripe papaya in the tropics as a breakfast fruit. For this
purpose it is cut lengthwise into portions and the seeds re-
moved. The placenta with the seeds attached may often be
removed without scraping the flesh, which is thus left in the
most attractive form for serving. Many prefer the choicest
fruits without other flavoring of any kind, but a little juice of
the lemon or the lime is a favorite accompaniment, while a few
prefer salt and pepper or even sugar. The green fruit when
fully grown may be cooked as summer squash, for which it
affords a very good substitute. The ripe fruit is used in maRk-
ing plapaya glaee.
The following recipes, taken from a book recently published,
give some directions for the use of this fruit :**

CHINA ORANGE AND PAPAYA MARMALADE. No. 1
To 1 measure papaya allow % measure China oranges. Wash

as pull). Boil again for 15 or 20 minutes.

MED)I('INAI, AND OTHER USES

Pl'ala \ bark is used in tIhe manufacturers of ropes. Nearly all
parts ofl the plant are credited with sollie medicinal value. The
roots afford a Ile-rve tonic. Thle seeds are said to be anthll-
llniltic. 'lilllolnaigie', aild carmiinative. lTheyv are also atell as
a delieae'y and as ia quencherl of thirst. The ripe fruit finds a
place as an inllgredient in certain sirups and elixirs. which are
said to be expectoralt. stedative, alnd tonic.
The most important iedlicinal property of tlie plant is found
in the milky juice. This is used by the natives of thle tropics in
the treatment of ecZenia, warts. intestinal worlms,. ullers, allnd
many kinds of foul sores. in diphtheria to dlissolve lhe false
Iiemlnralnes in tlie throat, and for numelrolus other ailments.

The ripe fruit is used as a cosmetic. a slice of it being rubbed
upon tlie skin to remove freckles and other blemishes. The
rleen fruit iland tile leaves are employed as soap to remove
stains from clothing. .
No single use of the papaya. except for food, is so common
in the tropics as that of thie milky .juice in rendering tough
meat tender. For this purpose a slice of the green fruit, rich
in juice. is rullbbed over the tliouhl flesh, or the latter is dipped
for a few minutes in a solution of the juice. Sometimes a
piece of the gr'eell fruit is put il tile water in which tlie meat
is boiled.





P~1APAYAI'1'R IN FLO'ARID)A


Another practice is to wrap the meat in papaya leaves over
night. or even to hang it in the papaya tree. The feeding of
'reen papayas to hogs is reported to make lhe pork tender.
Some of these Iractices are of doubtful efl'icay. Some writers
recommend mixing ginger with the juice when it is to le ap-
plied to meat.
