cal of energy.
8. USES
Custard apple is the “fruit of poor people”. Pulp is used in ice
creams and puddings.
Products such as jam, jelly, squash, syrup, nectar, canned
product and a fermented alcoholic beverage.
Fruits, seeds, leaves and roots of custard apple are valued for
their medicinal properties. As well as used both in ayurvedic
and yunani systems.
Seeds containing 30% oil which is extracted and used in soap
and paint industries.
Leaves are used for preparation of blue or black dyes.
Seeds are used for abortifacient and roots are drastic purgative
agent. Seeds , leaves ,young raw fruits are used for making
insecticides and lice killers.
9. BOTANY
Growth of the plants are shrubs or small trees growing
up to 5 to 6m.
The leaves are alternate simple and entire.
Flowers are born either singly or in small groups,
yellowish green, hermaphrodite. protogynous and
having auxillary bearing habit.
Fruits are heart shaped, fleshy syncarp formed by the
fusion of the pistils and receptacle, pericarp is the
edible part.
Pollination is mainly by insects i.e. cross pollination.

sweetsop)
Good quality
Widely Cultivated in India
19. VARIETIES
Cultivars are grouped based on the external fruit colour.
A. Red type : having red color, smaller
leaves and fruits.
B. Green type : having more popularity
in India.
20. 1) BALANAGAR

sugar.
3) MAMMOTH

Good quality fruit
21. 4) BARBADOS SEEDLING

Late season variety.
5) RED SITAPHAL
This variety originated as a chance seedling.

Having average quality and more number of seeds.
22. 6) KAKARLAPAHAD
Very high yielding variety.
It is very sweet and crispy in nature.
7) APK (Ca) 1
Released from RRS, Aruppukottai, TN during 2003.

24.5*Brix.
23. IMPORTANT HYBRID VARIETIES
1) ARKA SAHAN
It is crossed between Annona atemoya X Annona
squamosa.
Released from IIHR, Bangalore.
Suitable for drought prone areas.
Fruits having long shelf life and slow ripening
character.
2) AFRICAN PRIDE
It is crossed between Annona cherimola X
Annona squamosa.
Having good quality fruits.
24. Recently released variety
TROPICAL SUN:
Released from Australian Custard apple growers
association (ACAGA).
Suitable for home gardens.
Ripening at room temperature.
25. CLIMATE
Custard apple is adapted widely to tropical climate
and prefers moderate winter and high humidity during
flowering time.
Trees cannot withstand frost and prolonged cold
weather. Continuous rains during flowering and fruit
set results in poor yields optimum rainfall is 60-80cm.
Strong wind causes limb damage , heavy flower drop
and fruit damage.
SOIL
Trees grown in wide variety of soils including sandy,
marginal and wasteland types.
26. Fertile, well drained sandy loam soils with neutral to
slight acidic PH give better performance.
Heavy soils and water logged conditions not suitable.
Water stagnation leads to shriveling of branches and
sudden death of plants. because stagnation should be
avoided.
27. PROPAGATION
Propagated by both seeds and vegetative propagation
Seed propagation :
Seeds extracted from ripe fruits are used for sowing.
Viability of seeds lasts for 3-4 years through best
seeds give best germination.
28. Before seed sowing seeds are treated, such as seeds
soaking in cold water for 40-70hours are treatment with
GA3(500ppm), improve the germination rate.
Vegetative propagation :
Grafting : In-situ cleft grafting is used, using the best root
stock are Annona cherimola and Annona squamosa.
Budding : patch, shield and clip budding.
29. CULTIVATION
Planting :
The custard apple fruits are planting in the square or
triangular systems.
Pits are made of 50-60 cubic cm, filled with top soil
and 25-30kg FYM.
Spacing : 6 X 6m
Time of planting : During June-July. After 1 or 2
rains the saplings are planted in the centre of the pit.
Shading, staking and watering should be done to
protect grafts after planting in the main field.
30. Manuring :
Application of nutrients to custard apple depends upon the
soil and climatic conditions.
Custard apple trees are well response to fertilizer
application in terms of increased vigour, production and
quality
Recommended By UAS, Dharwad
1-2 year - 75:50:50 NPK (kg/ha)
3-5 year - 150:100:100 NPK (kg/ha)
>5 year - 250:125:125 NPK (kg/ha)
31. TRAINING AND PRUNING
Strong tree frame work in custard apple is obtained by
training young plants during the initial stages of
growth.
Keeping single stem up to 50 – 70 cm height and then
inducing scaffold branches in all directions makes
good frame work of tree.
To avoid crowding, proper space among the branches
is maintained by removing criss - cross and over
lapping branches.
Custard apple generally bears on the new growth but
some times fruiting also comes on old branches.
Therefore, suitable combination of young and old
branches should be maintained by judicious pruning
and which balancing the vegetative and reproductive
growth.
32. FLOWERING AND FRUITSET
Plants starts bearing after 3-4 years.
Flowering period commences from March-April and
continuous to July – August, the peak timing April
and May.
Very low fruit set in custard apple is a problem under
natural conditions, 1 – 8% fruit set is reported.
The main reason being poor pollination due to various
external and internal factors like dichogamy,
hypogyny.
The external factors like high and low humidity
prevailing at the time of flowering , soil moisture
stress.
33. Hand pollination can be practiced to increase fruit set to
get better sized fruit and ensure better market price.
Fruits can be improved by application of growth
regulators, GA (50ppm) at blooming stage, Biocil
(1ml/litre) just prior to flowering.
34. HARVESTING
Custard apple is a climacteric fruit, which ripens after
harvesting hence should be harvested at matured
stage.
Fruits mature in about 100 -120 days from anthesis.
Maturity indices:-
Changing fruit colour in to light green.
Fruits has attained full size.
Yellowish white colour has been developed between
the segments.
Initial cracking in carpels.
35. Post harvest management:
Fruit has very poor shelf life therefore for distant markets.
Harvesting comparatively harder fruits is advised.
Fruits harvested before proper maturity do not ripe well
and remain less sweet.
Arka sahana has better shelf life.
36. YIELD
A well managed grown up custard apple plant can produce
80- 100 fruits/ tree.
Arka sahana hybrid produces 25 tonnes fruits/ ha.
Older trees rarely exceed 100 fruits/ tree unless hand
pollination.
