Introduction
Jackfruit (Artocarpus heterophyllus), often called the “poor man’s food” in Eastern and Southern India, is now gaining global recognition as a superfruit. It is the largest tree-borne fruit, with individual fruits weighing up to 30–40 kg. Jackfruit is rich in vitamin A, vitamin C, potassium, calcium, carbohydrates, and fibre. Both ripe and unripe fruits have culinary and industrial uses—ranging from curries, pickles, and papads to chips, dehydrated slices, and even vegan meat substitutes. Seeds are roasted or boiled as nutritious snacks, while leaves and peel are used as fodder.
With increasing demand in domestic and export markets, jackfruit farming is now becoming an attractive crop for small and large farmers alike.
Nutritional and Economic Importance
-
Nutritional Value: Jackfruit is rich in vitamins, minerals, and antioxidants, which support immunity, digestion, and heart health.
-
Culinary Uses: Tender fruits are used for curries, pickles, and papads; ripe fruits are used for desserts, juices, and jams; seeds are used as flour and for snacks.
-
Industrial Uses: Processed into chips, dehydrated jackfruit, and vegan meat alternatives.
-
By-products: Leaves, rind, and waste serve as cattle feed.
-
Economic Value: With yields of 30–40 tons/ha and good market prices, jackfruit can generate high profits for farmers.
Climate and Soil Requirements
Jackfruit grows best in warm, humid, tropical and subtropical regions, up to 1500 m above sea level.
| Factor | Requirement |
|---|---|
| Temperature | 22–35°C |
| Rainfall | 1000–2500 mm, well-distributed |
| Elevation | Up to 1500 m |
| Soil | Deep alluvial, well-drained loam, red laterite soils |
| Soil pH | 5.5 – 6.5 |
It is sensitive to drought during the young stages and waterlogging at any stage.
Popular Varieties
Jackfruit has several cultivars, suited for different regions:
| Variety | Features |
|---|---|
| Gulabi (Rose-scented) | Sweet aroma, soft flakes |
| Champa / Champaka | High-yielding, large fruits |
| Hazari | Medium-sized, crisp bulbs |
| Rudrakshi | Distinct taste |
| Swarna | Hybrid, disease-resistant |
| GKVK-1 | Popular in South India |
| Singapore / Ceylon Jack | Commercial type, large fruits |
| Palur-1, Burliar-1, Pechiparai-1 | High-yielding regional selections |
Propagation Methods
Jackfruit can be propagated by seeds, grafting, and air layering:
-
Seed Propagation: Seeds should be sown immediately after extraction, as they lose viability quickly. Soaking in NAA (25 mg/L) for 24 hrs improves germination.
-
Air Layering: One-year-old shoots from bearing trees give success when treated with IBA (500 ppm).
-
Epicotyl Grafting: Seeds raised in polybags; seedlings (12–14 cm height) used as rootstock. Scion sticks from elite varieties grafted for uniform yield.
-
Softwood Grafting: Widely used in commercial orchards for true-to-type plants.
Land Preparation and Planting
-
Pit Size: 1 m × 1 m × 1 m pits dug and filled with topsoil + 10 kg FYM.
-
Planting Time: June–August (monsoon) is best; irrigated areas allow extended planting till December.
-
Spacing:
-
Normal orchards: 8 m × 8 m or 10 m × 10 m.
-
High-density orchards: 6 m × 6 m with regular pruning.
-
Fertiliser and Manure Management
Jackfruit requires both organic manure and chemical fertilisers for high yields.
| Tree Age | FYM (kg/tree) | N (g) | P₂O₅ (g) | K₂O (g) | Other |
|---|---|---|---|---|---|
| Non-bearing | 20–30 | 200 | 320 | 960 | 5 kg wood ash |
| Bearing tree | 80 | 600 | 300 | 240 | – |
-
Fertilisers applied in two split doses: June–July and Sept–Oct.
-
Irrigation after application improves uptake.
Intercropping
During the first 3–4 years, farmers can grow vegetables, pulses, and legumes between rows. Suitable intercrops:
-
Vegetables: radish, brinjal, chilli, cabbage.
-
Pulses: cowpea, horse gram, black gram.
-
Cover crops improve soil fertility and weed suppression.
Training and Pruning
-
Maintain a single straight trunk.
-
Remove side branches up to 1.5–2 m height.
-
Allow branching above the trunk for a strong canopy.
-
Remove vegetative shoots from the trunk where flowers appear.
Irrigation and Water Management
-
Mostly grown as a rainfed crop.
-
Young plants need irrigation every 12–15 days during dry periods.
-
Protective irrigation in summer improves fruit set.
-
Avoid waterlogging.
Weed Management
-
Mulching with dry leaves reduces weeds.
-
Manual weeding around the base of plants.
-
Intercropping and cover crops suppress weed growth.
-
Herbicides can be used carefully under integrated management.
Pest and Disease Management
Major Diseases and Control of Jackfruit
