Coffee

https://agri.bot/crop-calendar/coffee

Coffee (Coffea arabica and Coffea canephora, locally called robusta) is grown on roughly 475,000 hectares in India producing around 350,000 – 360,000 tonnes of clean coffee per year, making India the seventh-largest coffee producer in the world and the third-largest in Asia after Vietnam and Indonesia. India is distinctive globally for being the only major coffee origin where virtually the entire crop is shade-grown under a two-tier native canopy — a sustainability feature that underpins premium pricings and multiple GI tags. Robusta accounts for about 70% of national output (mostly in Kerala Wayanad and Karnataka Chikmagalur / Hassan lower-elevation estates) and arabica about 30% (mostly in Kodagu / Coorg higher elevations, the Araku Valley tribal belt and the Nilgiris / Shevaroys / Pulney hills of Tamil Nadu). India exports around 70 – 75% of its production — the three largest buyers are Italy, Germany and Belgium — making coffee one of India's most valuable plantation export earnings after tea and spices. The industry is regulated by the Coffee Board of India (Bengaluru) under the Coffee Act 1942, and the public-sector research is anchored at the Central Coffee Research Institute (CCRI) Balehonnur in Chikmagalur district (established 1925) with sub-stations at Chettalli (Kodagu), R.V. Nagar (Visakhapatnam) and Chundale (Wayanad). GI-tagged Indian coffee origins include Monsooned Malabar (Karnataka / Kerala), Coorg Arabica, Chikmagalur Arabica, Wayanaad Robusta, Bababudangiri Arabica and Araku Valley Arabica (the first tribal-cooperative GI coffee in the world).

Twelve-month operations

Fertilizer schedule

CCRI (Balehonnur) and Coffee Board package of practices recommend approximately 140 – 160 kg N + 90 – 120 kg P₂O₅ + 120 – 160 kg K₂O per hectare per year on bearing arabica and 200 – 240 kg N + 150 – 180 kg P₂O₅ + 200 – 240 kg K₂O/ha/yr on bearing robusta, applied in three to four equal splits — pre-monsoon (Mar – Apr with the blossom-shower irrigation), onset of south-west monsoon (Jun – Jul), post-monsoon (Sep – Oct) and a light pre-harvest / backing-dose (Dec – Jan on robusta). Organic manuring: 10 – 15 tonnes of well-decomposed cattle manure or compost every 2 – 3 years with heavy mulching of fallen leaf litter and pruned shade-tree lopping (Grevillea robusta / silver oak, Erythrina, Albizia, Dadaps) sustains the two-tier shade canopy and feeds soil organic carbon. Micronutrients — zinc sulphate (0.5%), boron (0.1% borax) and magnesium sulphate (0.5%) foliar sprays — at the Mar blossom-shower stage correct common Zn / B / Mg deficiencies on heavily cropped acidic Western Ghats soils. Soil pH optimum is 5.5 – 6.5 (coffee is mildly acidophilic); dolomitic lime at 500 kg/ha every 3 – 4 years is applied if soil-test pH drops below 5.0.

Pest & disease management

White stem borer (Xylotrechus quadripes) is the single most damaging pest of arabica in India — the grub bores into the main stem, ring-barks the plant and causes 20 – 30% plantation loss on neglected estates; management is strictly tracing-and-trenching infested stems, swabbing with chlorpyrifos / lindane-free Coffee Board-approved formulations, and planting resistant Sl-9 / Sln-9 arabica selections released by CCRI. Shot-hole borer (Hypothenemus hampei, the coffee berry borer / CBB) is the main robusta pest — it bores into the ripening cherry and taints the bean; management is prompt gleaning of fallen cherries, pheromone traps (brocap traps) and the egg-parasitoid Prorops nasuta where available. Mealybugs (Planococcus citri on berries, Planococcus lilacinus on roots) and brown scale (Saissetia coffeae) flare on shaded sections during the Mar – Jun pre-monsoon window — managed with soap-oil sprays, pruning of water-sprouts and Coffee Board-approved systemic insecticides at scouted threshold. Leaf rust (Hemileia vastatrix) is the main foliar disease of arabica (the pathogen that destroyed Sri Lanka's coffee industry in the 1880s) — pre-monsoon prophylactic copper oxychloride (0.3%) or Bordeaux mixture (0.5%) sprays and resistant Sln-9 / Sln-10 / Chandragiri arabica selections. Black rot (Koleroga noxia) is the main monsoon disease on shaded sections — pre-monsoon copper spray and shade regulation. Nematodes (Pratylenchus coffeae, Meloidogyne spp.) affect arabica roots — manage with grafting on resistant robusta rootstock (the standard CCRI recommendation for nematode-infested replant sites).

Irrigation

Coffee is grown under the high-rainfall Western Ghats regime (annual rainfall 1,500 – 3,500 mm, well distributed through the south-west monsoon from June and the north-east monsoon from October). Supplementary 'blossom-shower' sprinkler irrigation at 25 – 40 mm in Feb – Mar is now near-universal on bearing arabica estates — the controlled wetting of flower buds synchronises blossoming and sets a uniform crop; it is followed 20 – 25 days later by a 'backing-shower' of similar volume to firm the fruit set. Robusta is less dependent on blossom showers but benefits from 20 – 30 mm sprinkler support in Mar – Apr on dry years. Mulching between rows and under-canopy with fallen leaf litter, Grevillea lopping and inter-row cover crops (Mimosa invisa, Stylosanthes guianensis) conserves soil moisture through the Dec – May dry window. Avoid waterlogging — coffee roots are sensitive to anoxia on heavy monsoon days; strict drainage on heavy Kodagu / Chikmagalur clay sections is critical through Jul – Aug peak monsoon.

Frequently asked questions

Where is coffee grown in India and which state is the largest producer?

Indian coffee is overwhelmingly a Western Ghats crop — Karnataka produces roughly 70% of the national output, with Kodagu (Coorg), Chikmagalur and Hassan the three main producing districts; the Bababudangiri hills in Chikmagalur are the historical birthplace of Indian coffee, where Baba Budan is said to have introduced seven arabica beans from Yemen in 1670. Kerala is the second-largest producer at about 20 – 23% of the crop and is dominated by robusta from Wayanad, with smaller arabica plantings in Idukki / Peermade and Palakkad. Tamil Nadu produces around 5 – 7% from the Nilgiris, Pulney / Palani hills around Kodaikanal, Shevaroys around Yercaud and the Anamalai hills — mostly shade-grown arabica. A fast-growing non-traditional belt in the Eastern Ghats — the Araku Valley of Andhra Pradesh (Alluri Sitharama Raju / Visakhapatnam) and Koraput / Rayagada of Odisha — is now a globally recognised tribal-cooperative GI arabica origin. The Coffee Board of India also runs an NER (North-Eastern Region) expansion programme in Nagaland, Mizoram, Manipur, Meghalaya, Arunachal Pradesh, Tripura and Assam.

What is the difference between arabica and robusta coffee in India?

The two species occupy different agroclimatic niches and give very different cups. Arabica (Coffea arabica) is grown at 800 – 1,600 m elevations with annual rainfall of 1,500 – 2,500 mm and a cooler 15 – 25 °C temperature band — Kodagu, Chikmagalur, the Araku Valley, Nilgiris, Shevaroys and Pulney hills; it accounts for about 30% of the Indian crop and gives a mild, aromatic, acidic cup that commands a premium in specialty markets. Robusta (Coffea canephora) is grown at 300 – 900 m lower elevations with higher rainfall (1,500 – 3,500 mm) and warmer 20 – 30 °C temperatures — Wayanad, lower Chikmagalur, Hassan; it accounts for about 70% of the crop and gives a stronger, higher-caffeine, more full-bodied cup used in espresso blends and instant coffee. Robusta is more pest-tolerant (notably resistant to leaf rust and the white stem borer that devastates arabica), yields 40 – 60% more per hectare, and is the production workhorse of Indian plantations. Many estates in the mid-elevation belt plant both species on different sections and increasingly inter-plant them for risk diversification. CCRI (Balehonnur) has released high-yielding arabica selections (S.795, Sln-6, Sln-9, Chandragiri, Sachimor) and robusta selections (CxR, S.274, S.3334) tailored to Indian agroclimates.

Why is Indian coffee called 'shade-grown' and why does this matter?

India is virtually the only major coffee origin in the world where essentially the entire crop is grown under a dense two-tier native shade canopy — a lower tier of nitrogen-fixing legumes (Erythrina indica / Dadap, Albizia lebbeck, Grevillea robusta / silver oak) and an upper tier of tall native evergreens (Jack, Rose-wood, Nandi, Hopea). This is a Coffee Board-mandated and CCRI-recommended practice that distinguishes Indian coffee from the sun-grown Latin American and Vietnamese production models. The shade canopy slows ripening (giving denser, more aromatic beans), reduces leaf-rust and berry-disease pressure (lower humidity, better air circulation), returns heavy leaf litter to feed soil organic carbon, supports endemic biodiversity (the Western Ghats estates are globally important Important Bird Areas / IBAs and are home to hornbills, giant squirrels, elephants and the endangered lion-tailed macaque) and lets estates qualify for Rainforest Alliance, UTZ, Bird Friendly and Fair Trade certifications that command 15 – 30% price premiums in European and North American specialty markets. The downside is 20 – 30% lower per-hectare yield than sun-grown Vietnam / Brazil systems — a trade-off that Indian coffee competes on through premium shade-grown GI origins and specialty markets rather than bulk commodity volume.

What are the GI-tagged Indian coffee origins and what makes each distinctive?

India has six registered GI (Geographical Indication) coffee origins under the GI Act 1999, each with a distinctive agroclimate and cup character. (1) Monsooned Malabar (Karnataka / Kerala) — a unique post-harvest process where cured green coffee is exposed to the south-west monsoon winds on the Malabar coast for 12 – 16 weeks, which bleaches the bean to a pale golden colour, swells it 1.5× and gives a mellow, musty, low-acid, full-bodied cup much prized in Italian espresso blends. (2) Coorg Arabica — the washed arabica from Kodagu district with a bright, winy, medium-bodied cup. (3) Chikmagalur Arabica — washed arabica from the Chikmagalur district with a balanced, mellow, mid-acid cup. (4) Wayanaad Robusta — washed robusta from the Wayanad plateau of Kerala with a strong, full-bodied, slightly chocolatey cup used in espresso. (5) Bababudangiri Arabica — the historical Bababudangiri hills origin of Indian coffee with a distinctive full-bodied aromatic cup. (6) Araku Valley Arabica — the Eastern-Ghats tribal-cooperative arabica from the Alluri Sitharama Raju / Visakhapatnam district, the world's first GI-registered tribal-cooperative coffee, famed for its chocolate-and-citrus notes and the Girijan Cooperative / Naandi Foundation development model. All GI coffees command 20 – 40% price premiums over generic Indian plateau coffee.

How is Indian coffee processed, sold and exported?

After harvest, ripe red cherries are processed by one of two methods on the estate. Wet / washed processing: cherries are pulped within 24 hours in estate pulperies, the mucilage is fermented off in soaking tanks for 24 – 36 hours, the parchment coffee is washed and sun-dried on cement / coir drying yards for 14 – 21 days to 10 – 12% moisture — this gives a cleaner, brighter 'plantation' cup (Plantation A, Plantation B grades) and is standard for premium arabica. Dry / natural processing: whole cherries are sun-dried directly on drying yards for 25 – 35 days to 10 – 12% moisture — this gives a fuller, more fruity 'cherry' cup (Cherry AB, Cherry PB grades) and is standard for most robusta and some specialty arabica. Dried parchment / cherry is then hulled, graded and bagged at licensed curing works. Price discovery happens through a mix of (1) Coffee Board e-auctions on the IndiaCoffee.org platform for registered buyers, (2) direct estate-to-exporter contracts for premium GI lots, (3) commodity contracts on the ICE-US (Arabica, Contract C) and ICE-London (Robusta) exchanges. India exports around 70 – 75% of its production — the three largest buyers are Italy, Germany and Belgium, which together take over 50% of Indian coffee exports. HS code for green coffee is Chapter 0901 (unroasted not decaffeinated 09011100, unroasted decaffeinated 09011200, roasted not decaffeinated 09012100).
