The document provides information about coconut including:
- Coconut is known as the tree of life and each part is useful. It is an important crop for over 1 crore people.
- The composition of coconut water includes 95.5% water, 0.1% protein, and minerals like calcium and iron. Coconut kernel is a rich source of vegetable fat yielding 60-67% oil.
- Major coconut growing countries include Philippines, Indonesia, India and Sri Lanka. The major coconut growing states in India are Kerala, Karnataka, Tamil Nadu and Andhra Pradesh.
2. Coconut called as Kalpa Vriksha (Tree of Heaven).
It is also called as Tree of Life, Tree of Abundance, Tree of
Plenty, etc.
Each and every part of the coconut palm is useful to man in
one way or another.
The word coco derives from the word monkey because the
nut resembles a monkey's face.
Coconut is an important crop. About 1 crore people
depends on its cultivation and processing.
48%of coconut produced is consumed as raw nuts,
30%for milling copra for oil extraction,
8%as edible copra and
4% for coconut cream, milk, and other by-products.

6. Origin and Distribution
Coconut originated and was domesticated
in Malaysia where it was widely distributed
It was taken in prehistoric times to the
mainland of Asia, and had reached East
Africa before 1492
All tropical areas are suitable for coconut
cultivation
Philippines, Indonesia, India, and Srilanka
are the major producer of coconut, in
world.
13. The Root
The coconut palm has an adventitious root
system as typical of a monocot, i.e., it
produces numerous uniformly thick roots
from the base of the stem almost
throughout its life.
The main roots measure 6 m in length on
an average and in rare instances they may
grow even up to 25 m. they are usually of
uniform thickness of about 8 mm in
diameter.
14. The total number of roots in a tree depends
upon its age and the environment.
they may vary from 1,500 to 2,500 in a tree
aged about 25 years and 3,620 roots in a 60
to 70-years-old tree.
The number of roots counted on a bole
usually varies from 4,000 to 7,000.
Coconut roots are also provided with
numerous lenticels-like outgrowths or
ventilators which may be called 'breathing
organs', 'breathing roots' or
'Pneumatophores', which help in the
exchange of gases.
16. Stem
When the bole reaches the full stage of its development, the
stem becomes visible.
The thickness of the stem generally depends upon the vigor of
the tree, hereditary variation and soil conditions.
In the initial years of the growth of the tree the stem gradually
increases in thickness and this thickness is maintained
throughout.
When the leaves grow old they are shed , leaving a rough
pitted scar on the trunk which encircles the whole stem.
From the counts of these scars the age of the trees can be
approximately determined, as roughly 12 to 14 such
successive scars left on the tree correspond to a year of
growth of the tree.
It is also possible to gauge the vigour of the tree from these
scars.
In a bearing tree the scars left by the inflorescence stalk may
be seen on the stem in the middle above the widest portion of
the leaf scar.
17. The Leaf
Every tree has a crown of leaves oriented at the top of the
trunk consisting of opened leaves and those in the bud in
various stages of development.
The number of leaves in the crown varies depending on the
conditions prevailing, viz., method of cultivation, nutritional
status of the soil, sunlight, etc.
In adult trees, the crown comprises about 30 to 40 opened
leaves.
There are generally four sets of leaves in the crown.
The first set consists of ten to twelve leaves counted from the
oldest leaf, from the axils of which the bunches have already
been harvested.
18. The second set consisting of ten to fourteen
leaves will be those supporting fruit bunches in
the different stages of development.
The third set includes ten to twelve opened
leaves in the axils of which are found spadix in
various stages of development.
The soft and brittle bud in the centre of the
crown is the most rapidly growing part of the tree
20. The Inflorescence
Inflorescence of the coconut are formed in the axils of every leaf
of a bearing tree
The coconut is a monoecious plant producing male and female
flowers separately on the same tree.
The inflorescence appears at first in the axil of a leaf as a pear
shaped flat structure.
At this time, it is completely protected by two sheaths and is
collectively known as the spadix.
The outer sheath is thick and fibrous while the inner one is more
yellow and often fibrous and somewhat flat in nature
Its size varies from 0.75 m to 2 m in length depending upon the
individual palm.
21. Flowering commences at 6-12 years of age.
Each spikelets bears about 200-300male flowers at top.
1-2 female flowers at base
Female flower are globose and about 2-3cm in diameter having
large ovary, with 3 locules and 3 nectary glands
The average number of female flowers per tree in the group
good is about 151
Medium about 120
poor only 41.
25. The Pollen
When the anthers are fully mature, the pollen
sacs burst along two longitudinal slits.
The pollen grains are spherical and smooth when
very fresh.
On exposure for a few seconds, they turn
ellipsoidal with a longitudinal groove in the
middle and they measure about 0.063 mm in
length and 0.020 mm in breadth at the centre.
In the mature pollen grain, there are three nuclei
one of which is larger than the remaining two.
26. The Fruit
The fruit of the coconut, botanically known as a fibrous drupe
and popularly the 'nut', consists internally of the
endospermous kernel with the embryo embedded in it and
externally protected by the fruit coat known as the pericarp
which consists of three distinct and well defined regions, viz.,
the exocarp or epicarp, the mesocarp and the endocarp.
The outermost region of the fruit coat is the exocarp (or
epicarp) which consists of a tough smooth and hard fibrous
skin where as in the ripe fruit it assumes green, red, yellow
or brown colour.
Within the kernel is a cavity which in the unripe fruit is
completely filled with the liquid popularly known as 'coconut
water'.
As the fruit ripens, this water gets very much reduced.

36. Soil
Coconut can be grown on variety of
soils.
Well drained deep sandy loam,
alluvial and red loamy soils are ideal
for its cultivation
Heavy clay soils and waterlogged
areas should be avoided
pH of soil should be 5.5-6.5
37. Climate
Coconut is a tropical crop and it grow
wel in warm humid areas with
alltitude of 1000m above the sea
level
It can be successfully grown in area
receiving rain fall of 750mm/annum.
Temperature should be 270C and
200hr of sunshins /year is ideal.
38. Propagation
Coconut is propagated through seed
nuts.
Coconut is cross pollinated one, it
does not breed true to type, by
means of a series of selection made
at different stages, it is possible to
eliminate poor quality seedlings.
39. The selection procedure
Selection of seed garden :
Seed garden should have high
yielding record.
Seed garden should contain a high
proportion of heavy bearers.
The garden free from pest diseases.
Palm located near cattle shed and
compost pits should be avoided
40. Selection of mother palms
Selection made based on following character :
Yield of palm :annul yield not <80 nuts, copra content should
not <150g.
Age of palm: should at lest 50 year, however, very old palm
>60year avoided.
Nature and disposition of leaf: should have 30 fully opened
leaves
Nature, number and sequence of production of
inflorescence : every leaf axil should have one inflorescence with
large numbers of spikes and 1-2 female flower.
Size and shape of nuts: medium sized nut with round and
oblong shape are preferred.
41. Collection and storage of seed nuts
Thin husked medium sized nut of 11-
12 months old are collected during
Oct – Mar
Seed nut should have high kernel
content, which positively related to
vigour and early germination of
seedlings
Seed nut should be stored in shade
for a minimum period of 60days
before sowing
42. Nursery techniques
Nursery site should be in partial
shade.
Preferably sandy soil is preferred
Open a trenches of about 0.5m
depth and 0.3-0.4 m width.
Apply aldrin 10% dust at rate of
12g/m2 to prevent termite
The nuts are planted in nursery after
on set of monsoon during May-
June.
45. Spacing and position seed nuts
Seed nut s are planted at spacing of
30x30.
They are planted in beds in trenches
25-30cm deep.
The nuts may planted vertically with
stalk end up.
Irrigate nursery regularly .
Apply BM and COC to avoid the
fungal infection.
46. Selection of seedlings
Seedlings are selected based on following
characters :
Early germination: should germinated within 5
months
Number of leaves: should have minimum 5 leaves
Girth of collar: should be 10 cm
Splitting of leaflets
Stunted and lanky seedling avoided
48. Planting
Plant seedlings in pits at a spacing of 9m x
9m in tall varieties,
7.5x7.5 spacing in dwarf varieties,
Dig pits of size 1m3 and fill up with rich
topsoil to a level of 15 cm from the
bottom. Plant seedlings at the centre of
pit, cover with soil up to collar level and
press around.

53. Multistoried cropping system in coconut
Cultivating a mixture of crops with different
heights (multi-storey) and growth characteristics
which together optimise the use of soil, moisture
and space.
Model Multistoried cropping
54. Under the multi-storey cropping system, perennial crops
(coconut, banana, coffee, papaya, pineapple)
annuals/biennials (root crops: taro, yam, sweet potato etc) are
interplanted to maximize productivity and income.
coconuts are usually planted first. When they reach a height of
4.5 meters (after 3-4 years), bananas, coffee and/or papaya are
planted. After sufficient space has developed at ground level in
about three to four years, root crops are planted.
At full establishment, the system develops different layers:
coconut (tallest) followed by banana, coffee, papaya (middle),
root crops and pineapple (lowest).
The multi-storey system is intended to make the best use of
resources (soil, moisture and space) for increased farm income.
It is also very effective against soil erosion.

59. Rhinoceros Beetle
Scientific name: Oryctes rhinoceros
Symptoms of damage
Beetle bores into central shoots, spathes and
petioles, chews the tissues, ingests the juice and
throws out dry fibrous part.
Attacked central shoot topples down and the tree
may be killed if the growing primordium is
destroyed.
Leaves of partly damaged crowns when grow show
characteristic 'V' shaped cuttings on the leaflet.
60. Adult feeding on leaf V shape mark on leaf
Control
Treat the manure pits with carbaryl dust, four times a year in January,
April, July and October.
Hook out beetles from crowns during July-September and fill the
holes with lindane dust and sand ( 1: 1) mixture.
Poison bait made out of rotting mustard, castor cake, toddy or dung
and lindane attracts the beetles.
61. Red Palm Weevil
Scientific name: Rhynchophorus ferrugineus F.
Symptomatology :
It is very difficult to detect the presence of the
pest infestation in the earlier stages of attack.
The grub begins its life inside the palm and
normally never comes outside.
Therefore neither the grub nor the damage
caused by it can be readily seen.
Sometimes, a few small holes Occur in the crown
or the soft stem from which pieces of chewed
fibers protrude and a brownish viscous liquid
oozes out.
65. contorl
Drenching of carbaryl 4gm/liter of water
Painting raw surfaces of palm with a mixture
of 10 ml tar and 10 gm lindane dust prevents
egg laying
Pheromone Traps
66. Scales
Scientific name :Aspidiotus destructor
Symptoms of damage:
Female lays eggs under its shield like scale.
Crawlers move out to healthy leaflets, cluster in
large numbers on the underside of leaflets feeding
on cell sap.
Leaflets turn yellowish and in severe cases wither
and dry.
In severe infestation scales may also congregate on
green nuts and suck sap reducing the quality
68. Mites
Scientific name:Eriophyes guerreronis
Symptoms of damage:
Colonies of mites live under inner bracts
of perianth and suck sap from tender
tissues.
Damage initially appears as a triangular
patch at the level of perianth which turns
brown later.
69. •Mites damage
Sprays of
dicofol,@1.5ml/liter twice
at weekly intervals are
recommended on buttons
and developing nuts on
bunches.
Spraying of neem
formulation (0.15% or
1500 ppm) @ 5 ml/litre of
water also controls the
pest.

70. Black-Headed Caterpillar
Scientific name:Opisina arenosella
Symptoms of damage
o Larva scrapes and feeds on the surface tissues of
the lower surface of the leaflet .
o It binds two halves of leaflets together,
constructs a gallery of silk and frass and lives
under it.
o Affected palm
o Attacked leaflets turn brown and dry up.
o Attacks only lower leaves and from a distance
these appear as if burnt.
71. Control:
Root administration of monocrotophos is
most practical and widely adopted method.
A dark brown active, pencil- thick root is
taken out, and its end cut slantly,
immersed into a container (polythene bag)
with 10 ml monocrotophos and 10 ml
water.
73. Stem bleeding
Symptoms
Exudation of a rusty brown liquid
from cracks of trunks
Control
Apply 1%
Boreaux paste
74. Control
Chisel affected tissue and dress the wound
with 5% Calixin (5ml in 100ml water).
Apply coal tar after 2 days. Burn off
chiselled pieces.
Avoid any mechanical injury to the stem.
To avoid spread of disease on to upper
portion of trunk, root feeding with 5%
calixin may be adopted 3 times a year -
April-May, Spetember-October and
January-February.
75. Root wilt Disease
Symptoms:
Yellowing and wilting of inner leaves
Leaf become flaccid, necrotic.
77. Bud Rot
The earlier symptom is the yellowing of one or
two younger leaves. Black spots appear on
spindle leaves.
In the later stages the spindle withers and drops
down.
The tender leaf base and soft tissues of the crown
rot into a slimy mass of decayed material
emitting foul smell.
78. Bud Rot
•Spray with 1% Bordeaux mixture during
May and September if the disease occur
frequently.
79. Harvesting of Coconut
Coconut usually mature 12-13
month after opening of
inflorescence.
In India harvesting done twice
a year & Sri Lanka 6 times a
year
Harvesting is done 45 day
interval during summer & 60
days interval during rainy
season in Kerala.
Harvesting methods

83. Coconut water
coconut water is the tender liquid inside the young
coconuts.
Serves as the suspension for the endosperm of the
coconut during their nuclear phase of development
Endosperm mature into their cellular phase and
deposit into the rind of the coconut meat.
Coconut water is available in fresh canned, or
bottled.
Served as fresh chilled or packaged in many places.
Often sold by many street venders.
Also found in ordinary cans, tetra packs, plastic
bottles
Bottled coconut water has a shelf life of 24 months.
84. In recent years, it has been marketed as a natural
energy or sports drink due to its high potassium and
mineral content.
Low levels of fat, carbohydrates and calories.
Unless the coconut has been damaged it is likely
sterrile
In Bhamian cuisine coconut water may be drunk by
itself or blended with condensed milk and gin to make a
drink known as ‘Gully wash’ or ‘sky juice’.
In recent years, it has been marketed as a natural
energy or sports drink due to its high potassium and
mineral content.
85. Medical use :
It is said that coconut water is identical to
human plasma and can be injected directly into
human blood stream.The story has its origin from
World War II where british and Japanese patients
were given coconut water intraveinously because
saline solution was in short supply. but doctors
today say that they would not be Inclined to set up
a coconut water for dehydrated patients. It could
be possibly cause elevated calcium and potassium,
which could be dangerous
86. Classification of coconut
