Health Benefits of Papaya
• Papaya contain 212 amino acids and several enzymes, including papain, a
proteolytic enzyme that has an anti-inflammatory effect on the stomach,
including swelling and fever that can develop post-surgery.
• Papain helps proteins digest faster, which discourages acid reflux, and has
demonstrated effectiveness in treating ulcers and even relieving irritable bowel
syndrome. Papaya seeds have been used in folk medicine to treat parasite and
MEDITIONAL EFFECTS OF PAPAYA
• Papaya have medicinal properties and used to treat several diseases and symptoms.
It is used to remove digestive problem.
• It is used as a folk medicine to remove pain.

• It provides protection against diabetic heart disease and cholesterol.
• Acts as a anti inflammatory agent.
• It provides protection from arthritis.
• It promotes lungs health.
• It also prevents cancer.
• It also helpful in reducing weight.
INHERITANCE OF SEX
• Papaya has male, female, hermaphrodite and some other complex sex forms.
• The sex of the flowers on the same plant undergo change with season, age, and
• The male flowers hangs on long trusses.
• The female flowers and hermaphrodite flowers hangs on small trusses in the axils
• Predominant 3 sex forms (male, female, Hermophrodite)
• Male is controlled by satellite chromosome
M1m = Maleness, M2m = Hermophrodite, mm = Femaleness
• Constitution in papaya -
• M1RRm – Sex reversing Homozygous male , M1Rrm - Sex reversing Homozygous
• M1rrm – pure male, M2m – Hermophrodite, mm – pistillate
• Male : female (Gynodioecious) = 2:1, Male : female (dioecious) = 1:1
• Red skin color is governed by inherent heterozygosity and recessive gene.
• Red skin color is present only in Gynodioecious papaya.
• 10% male plant require in dioecious cultivar.
• Sibmating is mostly done in papaya. 11
GENETICS OF SEX EXPRESSION
• Sex expression in papaya is controlled by a single gene, with three alleles which
have a pleiotropic effect.
• The sex homologues were designated as: M for male, MH for hermaphrodite and m
• All combinations of dominant alleles, such as MM, MHMH and MHH, are lethal to
• This makes all males and hermaphrodite into enforced sex heterozygote's. Twenty-
five percent of the seeds in their fruits are non-viable.
• The genotypes for sex are Mm for female, MH for hermaphrodite and mm for
• Using these sex genotypes, there are eight possible cross combinations that could
be made with various segregation ratios, as indicated.
• Self-pollination in males, cross-pollination between males, and cross-pollination
between males and hermaphrodites, can all be done using the sexually ambivalent
males (SAMs) that produce perfect flowers during certain periods of the year.
• Male and hermaphrodite trees undergo various degrees of sex reversal, depending
on seasonal changes and climate.
• The female tree is the most stable form. 12

• Sexual Method -propagated by seeds.
• Wash the seeds and remove then gelatinous covering as this can inhibit
• Raise 3-4 seedlings per container and plant in field when they are 20 cm high.
• Seed treated with Thiourea (100-200 ppm) and Gibberellic acid (GA3 at 200
ppm) germinated better.
• Seed germinates in 2 weeks.
• Seedlings ready for transplant in 10 weeks.
CHOICE OF THE SEED
• The seed selected from Hermaphrodite plant.
• Select the best trees in the plantation (color, yield, fruit shape, hermaphrodite).
• Cover the flowers with a bag once they form to ensure self- pollination and mark
these flowers. Seeds are collected them at maturity.
• Seed rate :
: 250-300g/h(Gynodioecious) : 400-500g/h(Dioecious) (20 seeds/g)

• Recent Techniques (Micro propagation and Tissue culture)
• tissue culture technique using Murashige and Skoog media supplemented with
• Shoot tip culture from seedling and laterals buds from female plants of Coorg Honey
Dew variety was successful.
• The tissue culture plantlets measuring 5.5 to 9.5 cm and hardened in plastic chamber
survived better when planted in the field.
• FOR OPEN FIELD PLANTING –
• the land is ploughed and harrowed twice.
• An elevated plot along the row is made by ploughing on barring with two passes on
each side. This will ensure proper irrigation and drainage.
• Organic fertilizer and manure should be spread and incorporated in the soil during
• Land should be free from weeds before planting.
RAISING OF SEEDLINGS
• Seed rate is 500 g/ha.
• Raised beds are prepared.
• Seeds are sown at 1cm depth with 15x2.5 cm spacing. Covered with fine mixture of
FYM + soil.
• Immediate watering should be done.
• Mulching should be done with dry leaves.
• Seed will germinate in 15-20 days. Seedling ready in 60 days. Bordeaux Mixture
(3:3:100) is sprayed against damping off.
• 1. Spring season (February-March)
• 2. Monsoon season (June- July)
• 3. Autumn season (October - November)
• The following plant spacing can be used:
1.8 m x 1.8 m = 3086 plants/ha for normally followed in most places.
1.25 m x 1.25 m = 6400 plants/ha for Pusa Nanha is best for high density
1.6 m x 1.6 m = 3906 plants/ha suitable for papain production.
• A triangular 2 x 2 planting design can be adopted for non mechanized cultivation,
and 2 x 2 x 4 in double rows for mechanized cultivation.
• Papaya high density planting at 1.2 m x 1.8 m (4262 plant/ha) yield 146 MT/ha
PLANTING SEASONS & PLANTING DENSITY
• The seedlings can be raised in nursery beds 3m
long, 1m wide and 1o cm high as well as in pots or
polythene bags. The seeds should be sown 1cm
deep in rows 10 cm apart and covered with fine
compost of leaf mould.
• Light watering should be done in the morning.
• The nursery beds covered with polythene sheet or
dry paddy straw to protect seedlings.
It may be sown directly, but normally, it is better to
be seeded to raise seedlings and transplanted.
1. Plastic bag or soft plastic pot sowing:
2. Seedling Tray sowing:
The seedlings raised in polythene bags stand
transplanting better then those raised in
Perforated polythene bags of 20 cm x 15 cm size of
150-200 gauge can be used as a container.
They are filled with a mixture of FYM, soil and
sand in equal proportion. 4-5 seeds are
sown in each bag & 3 seedlings are
A. Transplanting stage:
When the seedling is 10 -15 cm tall, it should be transplanted, but 30-40
cm is also all right if it is grown in a larger container.
1.8 m x 1.8 m = 3086 plants/ha
2.0 m x 2.0 m = 6400 plants/ha
C. Pollinator Plants:
Minimum10-20% Male plants are required for pollination.
D. Planting method:
(A) Black-and-white plastic mulching film on the beds can be used to:
(a) Reduce the loss of water and fertilizer nutrient
(b) Control weed
(c) Repel the winged aphids
(d) Decrease virus infection at young stage
(e) Decrease bed soil erosion.
REMOVAL OF MALE PLANTS
• About 10% of the male plants are kept in the orchards for good pollination where
dioecious varieties are cultivated. As soon as the plants flower, the extra male plants
Removal of Male Plant 1. 2.
• To minimize flower drop or fruit drop, irrigate the plants before the soil gets dry to
avoid fungal infection.
• Soil is aerated time to time through shallow cultivation to avoid root rot.
• After transplanting, make sure the plants get adequate water every 2-3 days until
they are well established.
• Water the papaya plants regularly especially when the climate is hot or dry to
prevent growth retardation, flower abortion and dropping of young fruits.
• We can use method of drip irrigation for efficient use of water.
• Salient features of Drip irrigation-
i. 65 to 70% water saving compared to control method.
ii. Crop attains early maturity.
iii. Crop quality and yield increased.
iv. Requires least land levelling.
v. Poor quality water can be used.

MANURES AND FERTILIZERS
• Apply 20 g in each of Azospirillum and Phosphobacterium at
planting and again after six months of planting.
• Deficiency of lime and boron has often been observed in papaya
orchards. Spraying of 0.5% Zinc sulphate and one spray of Borax
(0.1%) may be done depending upon the nutrient status of soil.
• Doses of regular fertilizers are as follows-
• Weeding is very necessary for papaya, to sanitize its immediate environment from
insect pests that climb the trunk like ants carrying aphids and scales.
• It will remove competitor for plant food nutrients in the soil.
• Weeds are host and vector carrier of pest and plant diseases.
• Clean an area of one meter radius around the base of the plant.
• Deep hoeing is recommended during first year to check weed growth.
• We avoid herbicides as much as possible since they kill microorganism in the soil
that helps enhance decomposition of organic wastes into fertilizer and plant food.
• Application of Fluchloralin or Alachlorin or Butachlorine (0.2g/ha) as pre-
emergence 2 months after transplanting can control all weeds for 4 months.
• Slash tall weeds in between the rows or pass them with harrow to keep them down.
• Maintain the cleanliness of the field at all times.
• Always remember the weeds can reduce by 25% your production.
• Biological Weed Control Bioagent: Insect:Octotoma scabripennis and Uroplata
giraldi Weeds:Lantana camara.
• Low-growing vegetables of short duration may be taken as inter-crops.
• An occasional thinning of fruits necessary to prevent overcrowding .
• Papaya also grows as filler or in plantations of other crops where spacing is
REMOVAL OF MALE PLANTS
About 10% of the male plants are kept in the orchards for good pollination
where dioecious varieties are cultivated. As soon as the plants flower, the
extra male plants are uprooted.
FRUITING OF PAPAYA
• Fruit hangs along the trunk.
• Flower borne in leaf axils.
• Most plants are dioecious but some gynodioecious varieties are also
present. Some flowers are hermaphroditic or perfect.
• Flower remains for four month and fruit ready for harvesting in another six
HARVESTING AND YIELD
• It is a climacteric fruit, so it should be harvested at mature stage.
• Usually fruits are harvested when they are of full size, light green tinge of yellow at
• We should harvest yellow green fruits as dark green fruits are not ripen.
• When the latex ceases to be milky and become watery, the fruits are suitable for
• While picking fruits from the tree, care must be taken that they are not scratched,
and are free from blemishes, otherwise these are attacked by fungus and start
decaying during marketing.
• On an average each plant of improved varieties bears 30-45 fruits, weighing 40-75
kg in one fruiting season.
• Average yield of 60-75 tons/ha may be expected in a season.

HARVEST AND POST HARVEST HANDLING
• The appearance of yellow color traces on the green fruit is an indication of
maturity and ready for harvest.
• The papaya fruits shall be harvested when 25% or ¼ of the fruit is ripen.
• Hold on the fruit, twist until it snaps or cut peduncle with a shape knife.
• Handle the fruit carefully to avoid bruising and unnecessary cuts.
• Never drop fruits to the ground. On tall trees, use ladder to reach and pick the
fruits by hand.
• Place the fruits gently on baskets with soft padding.
• Fruits should be delivered to the packing house of cannery 2-4 hours from
• Heavily bruised, damaged, diseased, over-ripe, or old fruits should be rejected.
• Schedule harvesting at least twice a week to minimize incidence of over ripe
