Jackfruit

Artocarpus heterophyllus

Also calledKathal (Hindi/Urdu) · Panasa (Sanskrit) · Chakka (Malayalam) · Kanthal (Bengali) · Nangka (Malay/Indonesian) · Bōluómì (Chinese) · Khanun (Thai)

Jackfruit bears the largest tree-borne fruit in the world, up to 50 kg and nearly a metre long, hanging straight from the trunk. It is the national fruit of Bangladesh and Sri Lanka, eaten ripe as a sweet fruit and green as a meaty vegetable.

The jackfruit or jakfruit is a fruit tree in the mulberry family of Moraceae. Native to India, the species was first described under the name Artocarpus heterophyllus in Encyclopédie Méthodique, Botanique in 1789 by Jean-Baptiste Lamarck, based on a specimen collected by botanist Philibert Commerson.

§1

What it can do

  1. iProduces the largest fruit borne by any tree, up to about 50 kg
  2. iiCauliflorous: fruit grows on the trunk and main limbs, which can bear the weight
  3. iiiA single tree can yield 100–200 fruit a year
  4. ivHeartwood yields a saffron-yellow dye used for Buddhist monks' robes

Toxic
Deadly

Eatenripe bulbs (arils) · unripe fruit (cooked as a vegetable or meat substitute) · seeds (boiled or roasted) · young leaves

All main parts are eaten. Sticky white latex in the rind and core is not poisonous but is very gluey; oil hands and knives before cutting. Raw seeds contain trypsin inhibitors and should be cooked.

In the medicine cabinet

TraditionUse
AyurvedaRipe fruit as a cooling, nourishing tonic; leaf ash applied to ulcers
Sri Lankan folk medicineLeaf decoction used for diabetes, with small studies on blood-sugar effects

Weight of evidence

Traditional. Long historical use; little or no modern clinical evidence.

Active compounds

USDA 10–12 (young trees killed near 0 °C). Survives winters down to about -1 °C.

Light
Full sun
Water
Moderate–high; tolerates a dry season but not waterlogging
Soil
Deep, well-drained loam or sandy soil, pH 5–7.5
Propagation
Seed (variable), or grafted/budded named varieties
To harvest
3–4 years from graft; 4–8 years from seed
Climates
Humid tropical, Monsoon tropical, Warm subtropical
  1. 1Plant a grafted tree or sow fresh seed directly where it will grow (8–10 m from buildings).
  2. 2Water well for the first two years and mulch heavily; feed young trees with compost every few months.
  3. 3Prune early to keep the tree low (4–6 m) and open, so fruit forms within reach on the trunk.
  4. 4Thin to one or two fruit per cluster; tie heavy fruit with cloth slings if branches are weak.
  5. 5Harvest when the spines flatten slightly, the fruit sounds hollow when tapped and it gives off a sweet smell; for vegetable use, pick young and green.

Marginalia

Pliny the Elder, drawing on reports from Alexander's campaigns, described a huge Indian fruit eaten by sages that some identify as jackfruit (others as the banana), and it figures in the ancient Tamil 'mukkani' (three fruits) of mango, banana and jackfruit. Its wood is prized for temple furniture and veena lutes in South India.

Curiosity

The heaviest jackfruit on record, verified by Guinness World Records, weighed 42.72 kg and was grown in Hawaii in 2003.
