Coffee

No. Coffee is not a CACP-notified crop and has no Minimum Support Price. It is regulated by the Coffee Board of India (a statutory body under the Ministry of Commerce and Industry), and price is set by auction and export demand — shaped by international benchmarks such as ICE/London coffee futures, Vietnam’s Robusta supply and Brazil’s Arabica supply. Most small growers in India sell their crop through the Coffee Board’s e-auction platform, through cooperatives, or to registered curing works, rather than at an APMC mandi.

It depends mainly on altitude. Arabica wants cool, high-altitude land (above roughly 1,000 m) and gives the finer, more prized cup, but it is more disease-prone (coffee berry disease, leaf rust) and yields less — about 400–500 kg clean bean/ha. Robusta tolerates warmer, lower elevations, is hardier, and yields two-and-a-half to three times as much (1,000–1,300 kg/ha), but sells for less per kilogram. A grower whose land sits below Arabica’s comfort altitude is generally better off with Robusta than fighting the climate.

Indian coffee estates deliberately use a two-tier shade canopy — usually silver oak (Grevillea robusta) or native trees — unlike the full-sun systems common in Brazil or Vietnam. Shade moderates temperature and moisture, reduces stress on the bush, and cuts pest and disease pressure that worsens in harsh direct sun. The same canopy very often also carries a pepper vine as an intercrop, making a well-run estate a three-layer system of shade trees, coffee and pepper on the same land.

The blossom shower is a specific pre-monsoon rain spell, usually in February–March, that triggers synchronised, fragrant white flowering across a coffee estate. A second rain spell 10–15 days later, the “backing shower”, sets the pinhead berries that follow. If either shower is late or missed, growers substitute with sprinkler irrigation — because flowering that is not properly triggered and set gives a patchy, uneven, smaller crop for the whole year.

CBD is caused by the fungus Colletotrichum kahawae, which produces sunken, dark, anthracnose-like lesions on green and ripening cherries and can rot the berry before the bean fully forms. It is one of the most damaging diseases on Arabica and can cut a crop by half or more if left unmanaged, especially in cool, wet conditions at higher elevation. Management combines CBD-tolerant selections like Cauvery/Catimor with a scheduled fungicide programme timed to the wet flowering-to-berry-set window.

White stem borer (Xylotrechus quadripes) is considered the single most destructive pest of Arabica coffee in India. Its grubs bore into the main stem near the collar; by the time the sawdust-like frass and bark cracking are obvious, the stem is often already girdled and the plant dies. Because there is no cure once a plant is badly infested, control is preventive — whitewashing stems, prompt removal of infested plants, and timed insecticide application during the beetle’s flight periods.

A coffee plant gives its first light crop 3–4 years after transplanting and reaches full, economic bearing a couple of years after that. Once mature, with proper pruning and shade management, the same plant keeps cropping every year for 20–30 years or more — the annual cycle of blossom shower, backing shower, berry development and picking repeats each year of that productive life.

In wet/washed processing, the outer skin and pulp are removed from the cherry mechanically soon after picking, the beans are fermented to remove the mucilage, washed, and then dried — this generally gives a cleaner, brighter cup. In dry/natural processing, the whole cherry is spread out and dried in the sun before hulling, which is simpler but needs even drying and careful handling to avoid off-flavours. The method chosen at picking has a major effect on the cup quality and price the lot fetches.

Yes — pepper vines trained up the shade trees are a very common intercrop on Karnataka and Kerala coffee estates. The shade tree becomes a living stake for the pepper vine, so the land effectively grows three crops — shade timber/fuel, coffee and pepper — at once, giving the grower an additional income stream from the same canopy.

Karnataka is by far the largest producer, growing over 70% of India’s coffee, concentrated in Chikkamagaluru, Kodagu (Coorg) and Hassan districts, and growing both Arabica and Robusta. Kerala is the second-largest producer, mostly in Wayanad, and grows almost entirely Robusta. Tamil Nadu, mainly the Nilgiris and Pulney hills, is a smaller producer that grows both species.

Arabica typically yields about 400–500 kg of clean (green) bean per hectare, while Robusta yields about 1,000–1,300 kg per hectare — roughly two-and-a-half to three times as much. Robusta’s much higher yield is offset by a lower price per kilogram than Arabica, so the two species land in a similar range on overall estate income, and the right choice depends more on your altitude than on which number looks bigger.

Arabica is typically planted at 2.5 × 2.5 m, giving roughly 1,600 plants per hectare. Robusta needs more room for its bigger canopy and is planted wider, at about 3 × 3 m, giving roughly 1,100 plants per hectare. Using Arabica’s tighter spacing for Robusta crowds the canopy, raises humidity-driven disease risk, and makes picking and spraying harder.
