Jackfruit
(Art
Carpus Lamk heterophyllus)
1. A BRIEF HISTORY
Jackfruit
is a fruit tree crop that originated in India and spread to the tropics,
Including Indonesia. In Indonesia, this tree has several regional names such as
Nongko / jackfruit (Java, Gorontalo), Langge (Gorontalo), Anane (Ambon), lumasa
/ malasa (Lampung), nanal or krour (Irian Jaya), jackfruit (Sunda). Some
foreign names are: jackfruit, jack (UK), jackfruit (Malaysia), kapiak (Papua
New Guinea), liangka (Philippines), peignai (Myanmar), khnaor (Cambodia),
mimiz, miiz hnang (laos), khanun (Thailand ), mit (Vietnam).
2. TYPES OF PLANTS
In
Indonesia, more than 30 cultivars in Java, there are more than 20 cultivars.
Based on the figure and size of the jackfruit tree is divided into two groups,
namely the jackfruit tree fruit and mini fruit jackfruit tree.
1) Large
fruit Jackfruit: reaching 20-30 m tall; stem diameter at 80 cm and age from
about 5-10 years to bear fruit.
2) small
fruit Jackfruit: reaching 6-9 m tall; Reaches 15-25 cm stem diameter and age
Began to bear fruit about 18-24 months.
Under
conditions of jackfruit pulp can be divided into three types, namely:
Jackfruit
pulp: pulp thin, somewhat fibrous, soft, flavorful hard easily separated from
the fruit.
Jackfruit
barked: flesh thick, slightly dry aroma is less harsh. (Jackfruit and jackfruit
boar bones)
Jackfruit
Camped: flesh thin, pliant and aromatic specific. Superior jackfruit varieties
grown in Indonesia, namely: jackfruit billing / boar jackfruit, jackfruit Camped,
jack tray, thick jackfruit, jackfruit turmeric, red jackfruit, jackfruit bark,
mini jackfruit and jackfruit misin.
3. BENEFIT PLANT
Young
jackfruit pulp (towel) used as vegetable food.
Jackfruit
seed flour is used as raw material for the food industry (food ingredients
mixed).
Young
leaves can be used as animal feed.
Jackfruit
wood is Considered superior to teak for furniture manufacturing, construction
lathe, mast, mast horses and stables for cattle (in Priangan), paddles, tools,
and musical instruments.
Jackfruit
tree can be used as traditional medicine.
4. PLANTING CENTER
Fruit is
even considered as the main staple food during food shortages. In Southeast
Asia, jackfruit is mainly kept in the yard and orchard fruit mix: in the 1980's
some extensive fruit orchard planted jackfruit as intercropping plants with Jackfruit.
Because the fruit is easy to rot, do not export trade to Australia, Europe and
so on from canning factories in Malaysia.
5. GROWING CONDITIONS
5.1. Climate
Wind
plays a role in helping pollinate flowers on the plant jackfruit.
Jackfruit
trees suitable to grow in areas that have the average annual rainfall of
1500-2500 mm and the dry season are not too hard. Jackfruit can be grown in dry
areas are in areas that have dry months over 4 months
Sunlight
is needed to spur jackfruit photosynthesis and growth, because trees are
intolerant. Lack of sunlight can lead to disruption of the formation of flowers
and fruit and growth.
The
average minimum temperatures of 16-21 degrees C and Maximum Temperatures from
31 to 31.5 degrees Celsius
High
humidity Necessary to reduce evaporation.
5.2. Growing Media
Jackfruit
trees are maintained in different types of soil, but more pleasure from
alluvial, sandy clay / clay argillaceous deep and well irrigated.
Generally,
the preferred soil is loose and sandy soil. This tree lives on barren land to
fertile soil with acidic reaction conditions to alkalis. Even in the peat soil
was this tree can grow and produce fruit.
Jackfruit
trees are resistant to low pH (acid soil) with a pH of 6.0 to 7.5, but the
optimum pH of 6-7.
Water
depth of suitable soil for the growth of jackfruit is 1-2 m or between 1-2.5 m.
Because the roots are very deep, it should be planted in the soil top layer
thick enough (about 1 m).
5.3. The Altitude
Jackfruit
tree can grow from start lowlands to 1300 m altitude. But the best altitude for
growing jackfruit is between 0-800 m above sea level.
6. Cultivation guidelines
6.1. Nurseries
1) Requirements for Seed
Generally
jackfruit plant propagation is done by using the seeds, because multiplication
with graft or grafting only a small percentage will be. This may be due to
latex content that may inhibit the process of unity. Selection made since the
time when you want to get jackfruit seedlings that are superior (rapid
Fruition, Able to produce a lot of fruit quality and resistance to Pests and
diseases). Some things to consider in choosing a good seed are:
Seed
should come from superior types or varieties (high production, good quality
fruit, long-lived and resistant to Pests and diseases).
Seedlings
should be healthy roommates can be seen from the figure the solid, strong
stems, and grows straight upright, branching many and the upper leaves of fresh
green and shiny.
2) Preparation of Seeds
Treatment
includes washing the seeds carefully to remove the skin and discard seeds slimy
pericarp part in the form of horns; treatment will improve germination. Seeds
sown while still fresh, and if Necessary short-term storage, the seed should
not be allowed to dry out. The seed, roommates owns 40% of the original water
content and stored in a watertight plastic container, with Temperatures of 20
degrees C is still able to germinate for 3 months. Under conditions of adequate
germination can be initiated after 10 days and germination percentage of
80-100% within a period of 35-40 days after sowing. Seeds should be placed
horizontally or hilumnya face down for germination. How jackfruit tree breeding
by grafting requires special skills and experience and Becomes a low
percentage. Advantages include faster fruitful and Mother Nature can
diturunkan.Tanaman used as the base of the seedling is jackfruit / Cempedak the
origin of the seeds.
How okulasinya are as follows:
Cut a
wooden eye (eye entraps) from jackfruit trunk, with skin approximately 2 cm
above to 2 cm below the eye. Carried Wood disposed of carefully to the eye
growing point is not damaged.
Cut the
base of the tree bark, about 10-20 cm above the root collar with a width of 2-3
cm and 3-4 cm in length. Ungkitlah of wood and kukit tongue was cut in half.
Put your eye to the base of the tongue under the bark of trees, in such a way,
the eye is still visible above the bark tongue cut out. Then tie with raffia
and eyes still sticking out (not to be crushed).
At the
successful grafting, after 8-14 days raffia rope should be discarded. When the
shoots are growing throughout 1-10 cm, tie shoots at the top of the tree, so
that shoots grow straight and not damaged because the wind rocked. Materials
for graft taken from young branches / twigs had been in the tree branches / twigs
new buds are buds on a branch or twig that has not been productive. Implants
done before the rainy season so that the roots can grow well. However, an
implant done in the dry season, but should be watered regularly.
How
grafting done by peeling skin around 3-5 cm in width. Wounds that have been
created are allowed to dry in contact with winds 1-2 days. Then the upper wound
hormone Root oiled one F, and then covered with soil or humus berkompos that
has been moistened and covered with coconut fiber or plastic roommates has been
given little holes.
3) Seed Seeding Technique
Seeds
sown / planted into plastic bags roommates are available in a deep bed of thick
seed, after it closed down a thin layer of soil. Seeds will germinate with an
average germination rate and percent to ± 90% of plants. Dipotkan young
seedlings at the latest after the leafy four strands, as older seedlings
difficult to transplanting (transplanting). This difficulty can be overcome by
1-2 sow seeds directly into the container. Most suitable seedlings kept in the
shade (50-70% intensity of full sunlight).
4) Maintenance Nurseries / Seeding
For
seedlings from seeds, watering is done regularly every morning. Seedbed should
be a shade that is not too tight and facing eastwards in order to prevent too
rapid evaporation of water. Of grafted seedlings, watering can is done every
day Regularly to Prevent dryness. Watering is done when there is no rain.
Seedling of grafts should be removed when a new shade that does not Wither.
5) Transfer of Seeds
Seedlings
to be transported to the field plantings should be watered first.
Transportation to field planting seeds in the morning or afternoon and be done
with caution. Demolition of seedlings in the field is done carefully as in the
transport. If the transport distance far enough seeds, the seeds of roommates
had been demolished Earlier admitted some days before planting. These seeds
(from seed) can be planted in the ground when she was young once, before the
roots grow out of the pot, the roots can cause disruption to the deadly seed.
Seedlings should have a size 50-75 cm tall and aged 1-1 1/2 months. Of grafted
seedlings can be planted in the field at the age of 6-8 months. If the length
of shoots had reached 2-30 cm, cut the top of the base of the tree and the
wound closed paraffin. For grafting should be done during clear weather and no
rain. Seeds of grafts, usually after 1 to 2.5 months, many rooted cuttings and
grafts can be taken. Once weaned a few days, grafts can be planted in the
field.
6.2. Media Processing Plant
1) Preparation
Before
planting activities undertaken, to do site inspection and determined based on
the results of field boundaries areal.Faktor factors that affect the growth of
crops such as jackfruit weeds, standing water, soil structure and texture
patterns should be addressed / controlled. For that act of cleaning the field
in total, setting drainage and tillage, especially in the planting hole to be
made.
2) Establishment of beds
Some of
the provisions that need to be considered in making nursery beds as follows:
Size beds
vary but are typically used between 5 x1 x 1 m and 10 m.
Seedbed
arcing north to south direction and edges reinforced with bamboo, bricks, or
wood and elevated surface 10-15 cm of the soil surface.
Between
beds is 0:45 m and 5-10 m beds made every road checks around 60-100 m.
Drains
made along the left and right hearing.
Seedbed
given shade with palm roofs or slalom. Section facing east is higher than that
facing the West.
In a
prepared seedbed plastic bags that have been filled with growing medium and
have been given small holes in the bottom. The media used to grow soil mix
topsoil, organic fertilizer, and fine sand in the ratio 2:1:1. Plastic bags
used size 20 x 30 cm with a thickness of 0:08 mm and black.
3) Liming
If the
soil pH is too acidic or alkaline it is Necessary to do some effort to the make
jackfruit can grow and provide optimal results. If too acidic (pH <5) lime
can be added, if it is too alkaline (pH> 7) can be added sulfur. The dose
depends on the condition of the land, but as a guideline of 1 kg of lime or sulfur
to 1 m 3 planting hole.
4) Fertilization
In the
planting hole, soil excavation results manure mixed with 20 kg / pit and
dolomite, 0.5 kg / hole (to raise pH). Soil mixture is inserted into the whole
2-3 weeks before planting. A week before planting grant NPK fertilizer
(15-15-15) 100 grams into the planting hole.
6.3. Planting Techniques
1) Determination of Cropping Pattern
Pattern-yard
effort in the land is planting around the house. This result is not merely to
sell but mostly for their own consumption. While the pattern of the planting
gardens in a much wider area of the
yard with a consideration of the results to meet their market requirements,
capital and labor reasonably available and in accordance with the requirements
of the land where grown jackfruit. Business pattern can be shaped garden plants
gardens garden pure and mixed crops. In gardens planted purely plant one crop
that is entirely planted jackfruit. While in the garden mix, mixed jackfruit
tree pineapple, papaya, and so on. Jackfruit trees are maintained in the
orchard planted within 8-12 m, in a square or hexagon pattern: a general
density was 100-120 stems / ha. Cropping distance between the planting hole 12
x 12 m or 4 x 6 m. 2) Preparation and Planting hole made Planting hole size of
0.5 x 0.5 x 0.5 m or 1 x 1 x 0.5 m. At the time of excavation pits, upper soil
is separated from the lower ground. Upper soil mixed with manure that has been
cooked up to 20 kg per hole. The hole has been excavated soil is left open for
1-2 weeks, in order to get sunlight so well oxidized. To avoid acid soil
constraints, dugouts mixed with dolomite / agricultural lime as much as 0.5 to
1 kg per planting hole and soil mixture is inserted into the whole 2-3 weeks
before planting. For Soils that are too heavy, besides tilling sand may be
added as much as 0.5 cans per hole. A week before planting grant NPK (15-15 -
15) 100 grams into the planting hole if Necessary. Seed yield or grafting
seedlings planted upright and firm in the middle of the planting hole. The
distance between the planting whole 12 x 12 meters and 4 x 6 meters
3) How Planting
Planting
late afternoon or early morning at the beginning of the rainy season when
rainfall is fairly evenly. Seedlings planted in the holes that are already
available, perpendicular. Before the seed is planted, plastic bags must be
removed. If planting is done outside of the rainy season or due to climatic
abnormalities, namely the rainy season turned into dry again suddenly, the
seeds that have been planted have to be watered regularly.
4) Making Holes in Mulch
Mulching
around the jackfruit tree is very necessary, especially during the dry season
to improve soil moisture. However, during the rainy season because the mulch is
not Necessary to bring fungal attack. Mulch can also be incorporated into the
soil as fertilizer organizational; administration of two times per year greatly
helped the growth of plants. Compound fertilizer plant made in Malaysia with a
dose of 2-3 kg per tree.
6.4. Plant Maintenance
1) Spacing and Stitching
Stitching
plants were carried out in the rain still falling in the first year and second
year.
2) Weeding
Weeding
or free plants from weeds or plant bully attack is done by clearing weeds
manually / chemical properties of jackfruit plant with a radius of 1-2 m. Weed
control using herbicides such as Chemically Parasol 1.5 liters in 600 liters of
water per hectare or Roundup 2-3 liters in 800 liters of water / ha. The first
weeding is done 1-2 months after planting, and then every 2-4 months were
Carried out for 2-3 years. Weeding is done by hand or chemically.
3) Fertilization
Organic
fertilizers such as manure or compost fertilizer 1-2 times a year as much as 20
kg per plant. Inorganic fertilizer made one week after planting at a dose of
100 g NPK per plant. Fertilization second at the age of 6 months at a dose of
150 g NPK per plant. The third fertilization performed on the plant life of 12
months at a dose of 200 grams per plant. Fertilization fourth at the age of 18
months at a dose of 250 grams per plant and fifth fertilization performed on
the plant life of 24 months at a dose of 300 grams per plant. Furthermore, for
plants that are not flowering in the fertile soil of organic fertilizer can be
added to 650 grams / tree.
Rise to
additional fertilizer plants need leaves to stimulate the formation of leaves.
Leaf fertilizer made after 2 weeks until the plants age of 17 months. Type of
foliar fertilizer used Gandasil D / Bayfolan.
4) Irrigation and Watering
Jackfruit
plants require good drainage. Irrigation is needed to increase of productivity.
Jackfruit plants have roots in, does not require flooding during the dry season
due to lack of tolerant plant jackfruit puddle. Its roots are Able to absorb
water in the soil. Provision of additional water required during the first two
years of growth.
5) Other Maintenance
Prune the
plant parts that are not fertile and productive. Pruning branches conducted on
jackfruit tree so lush entitled unobstructed sunlight to stimulate flowering.
Pruning is limited to shoot thinning when trees Began to be planted and little
cutting branches containing fruit to make it Easier to reach the fruit wrapped
and then harvested. Pruning branches intended to regulate conception, because the
female flowers appear on the main trunk or primary branches. Stimulation of
flowering is done by wounding, drill / tie rod. Purpose of treatment to inhibit
the assimilation proceeds in order not meyebar leaves to all parts of the
plant, but to stimulate flowering. In order jackfruit and the results are good,
do fruit thinning. The fruit that started growing them in a bag / paper that
has dicelupakan cement into the insecticide solution. Can also be wrapped with
woven leaves, for example using palm leaves or coconut matting. This action can
deterministic rats or bats attack, and compelling to Repel ants and other insects
in order to OBTAIN Whose fruit skin is smooth and bright.
7. Pests and diseases
7.1. Pest
Caterpillars
are daphnia causals shoot borers, creating a tunnel through the buds, young
shoots, and fruit. Cutting the affected Deciding leaves for caterpillars life
will become pupa in the tunnel; fruit wrapped or covered with sprayed
insecticide Théoden 35 EC. Fueling bark; such as caterpillars and Backer
rufomaculata Indarbela tetraonis eradicated with their funk holes / sprayed
with a systemic insecticide containing the active ingredient Charbroil (Sevin
85 S). Snout beetles (Weevil) attacking brown buds, Ochyromera artocarpi, a
typical pest jackfruit. Tempayaknya (grubs) into the bud and fruit is still
soft, the adults feed on the leaves. Parts of plants attacked destroyed and
required insecticide. Menyeruaknya winged beetle membranes (Spittle bug),
Cosmoscarata relate, eating young leaves. Nymphs live together in a mass of
foam roommates is secreted by them; nymphs collected and destroyed. The larvae
of the fruit fly are Daces dorsal and D. Often cumbrous attacks the fruit. To
avoid attacks, jackfruit should be wrapped; fruits are ripe or overripe
bergeletakkan not be allowed on the ground, but should be buried in the grave,
and spraying the temple to do. Other Pests are an assortment of sucking
insects, such as flea's flour, aphids, white flies, and 'trips', also
caterpillar's adhesive leaves (leaf Webber). Jackfruit other Pests are beetles
Heliopolis (Mirada, Hemisphere). Ladybug nymphs and adults suck the fluid young
plant parts (leaves and fruit). Egg size 1.5 m, laid out in a way stuck into
the plant tissue. The Incubation period is 5-7 days. Nymph and adult ladybugs
varies color, green or yellow-black and orange-yellow. Experiencing 5 times
during instar. Ladybug adults ranged from 6.5 to 7.5 mm in length with the
ability to lay up to 18 eggs. Several natural enemies such as the form of the
parasite are Euphoric Heliopolis, Heliopolis Erythmelus and as predators are
Sycuans leucomesus, Isyndrus sp. and Cosmolestes pities. To control the
population is controlled by natural enemies usually when high Populations do
with insecticides such Lunate 25 WP, Atabron 50EC.
7.2. Disease
Bacteria
die flunky (Erwinia carotovora) are attacking jackfruit tree, also Cempedak.
Mushrooms were first attacked the shoots and down next to the header. Violent
attacks kill the tree. In India Reportedly attack root rot and stem rot by
Rhizopus fungi that cause loss artocarpi plants up to 15-30%. This fungus is
generally subjugating flower buds. Some diseases are quite important between
Colletotrichum lagenarium, artocarpina Phomopsis, Septoria artocarpi and
Corticium salmon color. Mushrooms are mostly strike during the rainy season.
Cutting the plants are attacked will also built a lot of the attacks, in
addition field sanitation and fertilization can improve plant health.
8. HARVEST
8.1. Characteristics and Harvest
Fruit
maturity is determined by the following criteria:
If the
fruit is pounded with objects (egg knife back) will sound loud.
Changes
in fruit color from pale green to yellow-green or brown.
Removing
the characteristic odor or smells good.
Soft
start and distance prickly thorn with a thorn of the other more broadly
Looks
like fruit leather will break.
8.2. How to Harvest
How
plucking ripe jackfruit is cut with a sharp knife handles and jackfruit was
lowered carefully. Large jackfruit tree that bears fruit at the age of 5-10
years, while mini jack at the age of 1.5 to 2 years. In general, ripe fruit
after 8 months since the flowers appear.
8.3. Harvest Period
Age 20-30
years maximum fruit production, since it has to be rejuvenated. Results of
fruit per year per tree vary generally range 8-12 fruits / tree / year.
9. Postharvest
9.1. Collection
Jackfruit
collected by the contractor or taken directly to the market and sold to
retailers or cleaved and released one at a time to be sold directly to
consumers.
9.2. Storage
Often
jackfruit pulp is extracted, cleaned, and sold in a state of fresh extracts. If
the supply is abundant, preserved jackfruit, how is this: fruit pulp separated
from seeds, then washed, flattened, and dried added sugar or syrup, or without
being given anything? Processed is sold as a dry cake. In peninsular Malaysia
were canning.
9.3. Other Handling
Meat used
to scent jackfruit ice cream and drinks / used honey jackfruit, concentrates,
or flour and used in the manufacture of beverages. Jackfruit seeds can be made
into jackfruit seed flour mixed one in the whole wheat flour for bread making.
Use of jackfruit seed flour as a partial substitution of wheat flour in making
cookies and BMC (Mixed Groceries).
