India is the world's largest coconut producer — having overtaken Indonesia and the Philippines in the mid-2010s — producing roughly 14 – 15 billion nuts a year from about 2.1 million hectares, with a per-hectare productivity around 9,000 – 10,000 nuts (the highest among the major producer countries). The four southern states — Kerala, Karnataka, Tamil Nadu and Andhra Pradesh — account for ~90% of national production. ICAR–CPCRI Kasaragod is the nodal research institute and the Coconut Development Board (CDB), Kochi is the statutory development agency under the Ministry of Agriculture & Farmers Welfare.

Twelve-month operations

Fertilizer schedule

ICAR-CPCRI package of practices recommends 500 g N + 320 g P₂O₅ + 1200 g K₂O per adult palm per year, split into two doses — about ⅓ in May – Jun with the pre-monsoon showers and about ⅔ in Sep – Oct post-monsoon — applied in a 1.8 m radius circular basin around the palm and incorporated by light forking. Organic manure 25 – 50 kg FYM or compost per palm per year is applied along with the first dose. Magnesium sulphate 500 g/palm/yr corrects the Mg deficiency common on sandy-loam coastal soils, especially in the Kerala root-wilt tract. Juvenile palms get a graded dose starting at ⅒ of the adult rate in year 1 and stepping up each year to the full adult rate from year 7.

Pest & disease management

The three biggest biotic threats are: (1) coconut root (wilt) disease (RWD) — a phytoplasma-caused systemic disease endemic to central and southern Kerala (parts of Alappuzha, Pathanamthitta, Ernakulam, Kottayam, Thiruvananthapuram, Kollam) and parts of Kanyakumari and south Tamil Nadu, with no cure, managed by uprooting severely affected palms and planting tolerant releases (Kalpa Sankara, Kalparaksha, Chandra Sankara) with full-dose nutrition; (2) eriophyid mite (Aceria guerreronis) — a microscopic mite under the perianth that causes triangular scarring on young nuts and nut-drop, managed by root-feeding neem oil 10 ml + 10 ml water per palm every 45 days and release of predatory mites; and (3) red palm weevil (Rhoynchophorus ferrugineus) — a lethal crown borer, managed by prophylactic crown-filling with neem cake or sand, pheromone trap mass-trapping, and early detection of entry holes on the stem. Also serious: rhinoceros beetle (Oryctes rhinoceros) on the crown and spear-leaf (naphthalene balls or castor cake in leaf axils, pheromone traps, Baculovirus and Metarhizium biocontrol); bud rot (Phytophthora palmivora) which kills the growing bud if the spindle leaf turns yellow and droops (Bordeaux mixture crown spray before the south-west monsoon); stem bleeding (Thielaviopsis paradoxa) (chisel out dead tissue and swab with Bordeaux paste); and leaf-rot disease on root-wilt-affected palms. Follow ICAR-CPCRI and CDB IPM advisories for the local pest profile.

Irrigation

Coconut is drought-tolerant but strongly responds to irrigation in the dry months (Dec – May). The CPCRI/CDB recommendation is drip irrigation at ~40 – 45 litres per adult palm per day, with lower rates for juvenile palms (10 – 15 L/day in year 1, rising with age). Basin irrigation ~200 L once every 4 – 7 days is the traditional alternative on canal-command soils. Water-stress during the April – May pre-monsoon period causes nut drop and reduced bunch size 10 – 12 months later, so summer irrigation protects the next-but-one harvest. Mulching the basin with coconut husk, dried leaves or coir pith reduces evapotranspiration and buffers summer heat; the palm is also sensitive to waterlogging and basins must be drained during peak south-west monsoon.

Frequently asked questions

Why is India the world's largest coconut producer, and which states dominate?

India overtook Indonesia and the Philippines in the mid-2010s to become the world's largest coconut producer by nut volume, and has held that position since in CDB and FAOSTAT statistics. India produces roughly 14 – 15 billion nuts a year from about 2.1 million hectares, with a national average productivity of about 9,000 – 10,000 nuts per hectare — the highest among the major producer countries, substantially above Indonesia and the Philippines whose average per-hectare yields are lower. The four southern states together account for about 90% of national production: Kerala has the deepest cultural and economic association with the crop and the largest number of small growers, Karnataka hosts the big copra-processing hub at Tiptur and the Dakshina Kannada / Udupi coastal belt, Tamil Nadu dominates copra and tender-coconut production through Coimbatore and Pollachi, and Andhra Pradesh's East Godavari district (Ambajipeta cluster) alone has one of the highest per-hectare productivity bands in the country. Odisha and West Bengal contribute from their coastal districts, and Lakshadweep and the Andaman & Nicobar Islands are important small-island producers. The lead agencies are ICAR–CPCRI Kasaragod for research and the Coconut Development Board (CDB), Kochi for development, extension and market intervention.

What is the coconut root (wilt) disease, where is it a problem, and how is it managed?

Coconut root (wilt) disease (RWD) is a lethal, systemic, phytoplasma-caused disease of coconut palms transmitted by the plant-hopper Proutista moesta and the lace-bug Stephanitis typica. It has been endemic to central and southern Kerala since the early 20th century — the classical hot-zone is parts of Alappuzha, Pathanamthitta, Ernakulam, Kottayam, Thiruvananthapuram and Kollam, with extension into Kanyakumari and parts of south Tamil Nadu. Symptoms are a progressive flaccidity and inward curving of fronds, yellowing, reduced nut set, smaller nuts, and eventually death of the palm after several years. There is no chemical cure. Management is strictly integrated and anchored by ICAR-CPCRI's regional station at Kayamkulam, which was set up specifically for the RWD programme: uproot and remove severely affected palms, replant with CPCRI's tolerant releases — Kalpa Sankara (hybrid of Chowghat Green Dwarf × West Coast Tall), Kalparaksha (a tolerant West Coast Tall selection) and Chandra Sankara (hybrid of Chowghat Orange Dwarf × West Coast Tall) — maintain full-dose fertilizer and magnesium sulphate to compensate for impaired root function, apply integrated pest management against the vector insects, and intercrop with banana, cocoa or pepper to maintain farmer income during replanting. The Coconut Development Board subsidises replanting on RWD-affected holdings through its scheme for replanting and rejuvenation of coconut gardens.

Which coconut varieties and hybrids does ICAR-CPCRI recommend, and how do farmers choose?

ICAR-CPCRI maintains the national coconut germplasm collection at Kasaragod and has released a long pipeline of varieties and hybrids under the AICRP on Palms. The tall varieties are the backbone of commercial copra and oil production: West Coast Tall (WCT) is the dominant tall across Kerala and Karnataka, and East Coast Tall (ECT) dominates on the east coast in Tamil Nadu and Andhra Pradesh — both start bearing in 6 – 8 years and yield 70 – 120 nuts/palm/year at maturity with high copra out-turn. The dwarf varieties are prized for tender coconut: Chowghat Orange Dwarf (COD), Chowghat Green Dwarf (CGD) and Malayan Yellow Dwarf come into bearing in 3 – 4 years with sweet, high-volume water and are grown around homesteads and in commercial tender-nut gardens in Tamil Nadu. The high-yielding Kalpa series includes Kalpa Pratibha, Kalpa Dhenu, Kalpa Mitra and Kalpa Shree. Hybrids — Kera Sankara (WCT × COD) and Chandra Sankara (COD × WCT) — combine early bearing of the dwarf parent with the sturdy habit and copra of the tall, yielding 100 – 140 nuts/palm/year with 20 – 25 g copra per nut. For the root-wilt-affected Kerala belt, Kalpa Sankara, Kalparaksha and Chandra Sankara are the recommended tolerant releases. Farmers choose by purpose (copra vs tender nut), agro-climate, and whether the plot is in the root-wilt zone, and source quality seednuts through CPCRI, state-run DH farms and CDB-registered seed gardens.

How does the Coconut Development Board support farmers and the coconut economy?

The Coconut Development Board (CDB) is a statutory body established in 1981 under the Coconut Development Board Act 1979, headquartered in Kochi, Kerala, under the Ministry of Agriculture & Farmers Welfare. Its mandate covers the entire coconut value chain and it operates several programmes that directly reach growers. On the production side, CDB runs the scheme for integrated farming in coconut holdings for productivity improvement (replanting and rejuvenation of senile and disease-affected palms, laying new gardens with quality planting material, integrated farming demonstrations), the development of coconut industry (coir, copra, oil, tender nut, neera, virgin coconut oil and value-added products), and extension through state-level Field Offices, Demonstration-cum-Seed Production Farms and the Coconut Development Officers posted at district level. CDB registers nurseries and seed gardens to assure quality planting-material supply, promotes Coconut Producer Societies (CPS), Coconut Producer Federations (CPFs) and Coconut Producer Companies (CPCs) as the farmer-aggregation structure, operates a market-intervention scheme for copra under the Minimum Support Price announced by the Government of India (with NAFED as the implementing agency in Kerala, Karnataka, Tamil Nadu and Andhra Pradesh), and runs the Friends of Coconut Tree (FoCT) programme to train young coconut climbers. CDB also publishes the quarterly 'Indian Coconut Journal' and maintains official area, production and price statistics that feed into FAOSTAT and APEDA Agri Exchange.
