Land Preparation

For planting, pits of 1mx1mx1m are dug in summer and then kept open in sun. It will kill harmful bacteria and protect crop soil borne pest and diseases. Then fill pits with Farm Yard Manure or well decomposed cowdung@20-30kg, Single Super Phosphate@0.5kg and Phorate@10-20gm. Plant 3-4seeds per pit. 

Sowing

Time of sowing

Optimum time for Jackfruit planting is in month of June -July. 

Spacing

For planting rectangular or square method of planting is use. In less fertile soil use Hexagonal system of planting. Depending upon soil use spacing of 8mx8m or 10mx10m or 12mx12m.  

Method of Sowing 

Direct sowing of seeds or transplanting of seedling in main field.

Propagation

Propagation by seeds

Fresh seeds or seeds store for less than one month are used for planting purpose. Seeds can be first sown in polythene bag and then transplanted to main field. 

Vegetative propagation

For propagation, patch budding, air layering etc. methods are used. Soft wood grafting is popular now a days. 

Seed

Seed Rate

When spacing of 12mx12m is adopted, near about 30plant are accommodated in one acre. 

Seed Treatment

Soak seeds in NAA solution@25ppm for 24hour before sowing. It will help in early germination of seeds along with good growth. "

 

Fertilizer

Nutrient Requirement (gm/tree)

YEAR NITROGEN PHOSPHORUS POTASH
1-3year 200 60 -
4-7year 400 240 120
7th year onwards 600 300 240

 

Jackfruit respond well to fertilizer. Apply 200gm of Nitrogen and 60gm of Phosphorus every year for one to three years plants. 

For four to six years plant, apply Nitrogen@400gm, Phosphorus@240gm and Potash@120gm every year.

Pruning and Training

No regular training and pruning is required. But to protect crop from insect attacked and diseases, remove weak, disease, dead branches at end of rainy season. 

Weed Control

Depending upon weed intensity carryout weeding operations. Use mulch to protect crop from weed attacked. It also help in proper growth of crop.

Intercrop: During initial years, i.e. till crop reaches to bearing stage (tree start bearing from 6-8 years), intercrops like chilly, bhindi, brinjal, and pulses like cowpea, horse gram, black gram can be taken as intercrop. 

Irrigation

In rainy season it does not required water. Provide irrigation depending upon rainfall intensity and frequency. Jackfruit crop required irrigation during initial 2-3 years afterward no irrigation is required. In heavy rain avoid water stagnation as it cannot survive in waterlogged conditions.

Plant protection

  • Pests and their control:

Bud weevil: They feed on tender flower buds and on fruits. If infestation is observed, remove infested shoots, flower bud etc.

Treatment: It can be controlled by spraying of quinalphos@400ml/150ltr water.

Bark Borer: It makes hole in bark.

To avoid its infestation, remove dead branches as it lays eggs on it. Clean bark portion and insert cotton ball soaked in kerosene in it. Then seal hole with mud. Moreover it can be controlled by spraying of methyl parathion 50 EC@500ml/150ltr water.

shoot and fruit borer.png

Shoot and Fruit borer: It is a major pest of jackfruit. Due to its infestation, tender fruits may get drops. It leads to yield loss of 30%.

Take spray of Carbaryl@4gm per litre of water during flowering stage. 

blossom rot.png

Blossom rot, fruit rot or stem rot: It is a serious disease of Jackfruit. If it is not controlled, then it can lead to loss of 15 to 32%.

Collect and destroyed infected leaves and fruits away from field. If infestation is observed, take spray of Bordeaux mixture@1 % or Copper oxychloride@2.5gm/liter of water.

Leaf Spot: Light brown spots are observed on leaves. In severe infestation, leaves get defoliate.

If infestation is observed, take spray of Bordeaux mixture@100gm/10Ltr of water.

Harvesting

Crop is ready for harvesting seven year after planting. Grafted plants gives yield from 4th year itself. Fruits are ready for harvesting 3 to 8month after flowering. Right time of harvesting is when fruit changes its colour from green to light yellow.  Depending upon variety, individual fruit weights about 3-15kg. On an average 20-32ton obtained from one acre. 

Post-Harvest

Jackfruit ripening takes place 3-5days after harvest. Not fruit but its ripe flakes are stored at low temperature. Research finding shows that ripe fruit can be stored for three to six weeks at 11-12.5°C with 85-95% relative humidity.
