Where coconut grows in India

Coconut grows best on India's coasts and islands, where the air stays warm and humid all year. Kew's World Checklist (read via GBIF) gives its native range as central Malesia to the south-west Pacific and records it in India, including Assam, the Andaman and Nicobar Islands and Lakshadweep, as introduced; ICRAF notes that it is unknown in the wild. ICAR-CPCRI says Kerala, Tamil Nadu, Karnataka and Andhra Pradesh account for more than 90 per cent of the area and production; it also grows in Maharashtra's Konkan, West Bengal and the islands. A news summary of the Coconut Development Board's 2025-26 expansion work (Drishti IAS, August 2026) also lists Odisha, Gujarat, Assam and Arunachal Pradesh.

ICAR-CPCRI lists what the palm needs: a mean temperature of roughly 27 °C (±5 °C), humidity above 60 per cent, full sun, roughly 2,000 mm of well-spread rain a year or irrigation instead, and deep, well-drained soil with no rock within 2 m of the surface. It grows well up to roughly 600 m and tolerates salty soil and a pH of roughly 5.0–8.0. TNAU Agritech adds that yield falls when the mean temperature drops below 21 °C, and that drier inland areas can still grow it where the subsoil stays moist, as in valleys or near tanks.

• Grows well: the west coast (Kerala, coastal Karnataka, Goa and the Konkan), the east coast (Tamil Nadu, Andhra Pradesh, Odisha and coastal West Bengal), the Andaman and Nicobar Islands and Lakshadweep.
• With care (our assessment): the humid east and north-east, and the drier interior of the southern peninsula, only on well-drained land with assured water in the dry months.
• Not suitable (our assessment): Rajasthan and the rest of the north-west dry zone, the northern plains, the dry tracts of central India and the Himalaya.

Why coconut will not do well in Rajasthan

Coconut is the wrong tree for Rajasthan. In our assessment, three things work against it: the air in the long dry season is far drier than the 60 per cent humidity the palm wants; winters are cold, and TNAU Agritech says yield falls once the mean temperature drops below 21 °C; and the rain is far below the roughly 2,000 mm a year it grows best with, so it would need heavy irrigation all its life. A seedling may survive a few years with daily care, but do not expect a healthy, fruiting palm. Native trees such as khejri, rohida or neem suit dry country far better.

How to recognise coconut

Look for one tall, unbranched grey trunk and a crown of very long, feather-like leaves with bunches of large nuts below them (Flora of Pakistan, Flora of China, ICRAF).

• Trunk: smooth, greyish and ringed, thick at the base, roughly 30 cm or more across (Flora of China); it may lean or curve (ICRAF).
• Leaves: feather-shaped, roughly 3–6 m long (Flora of Pakistan, Flowers of India), with up to about 100 leaflets on each side (Flora of China) and no thorns (ICRAF).
• Flowers: small and pale yellow, in branched clusters that come out of boat-shaped sheaths among the leaves, with many small male flowers and fewer, larger female flowers (ICRAF).
• Fruit: very large, roughly 15–25 cm long or more (Flora of Pakistan; Flora of China gives up to 30 × 20 cm), green, yellowish or reddish brown, with a thick fibrous husk around a hard shell that has three "eyes" at one end (ICRAF).
• Look-alike: the areca nut palm (Areca catechu), whose nut is supari, has a much slimmer trunk, roughly 10–20 cm across, a smooth green sheath just below the leaves and small yellow, orange or red fruits up to roughly 8 cm long (Flora of China).
