Cocoa under coconut/oil-palm shade
Cocoa (Theobroma cacao), the source of cocoa beans for chocolate and confectionery, is grown in India principally as a shade-loving intercrop under coconut, arecanut and oil-palm canopies in Karnataka, Kerala, Tamil Nadu and Andhra Pradesh. Research on cocoa in India is led by ICAR-CPCRI through its regional station at Vittal, which has bred a series of VTL clones and hybrids adapted to palm-based systems.
Cultivation context
Cocoa requires diffuse shade, high humidity and well-drained soils. By planting cocoa as a second tier under established palm orchards, growers utilise the same drip and labour infrastructure and obtain a second cash crop from the same land. CPCRI recommended spacings vary with the overstorey:
- Under coconut: 7.5 x 7.5 m (around 500 plants/ha)
- Under oil palm (Oil Palm Cultivation): 4.5 x 4.5 m (around 400 plants/ha)
- Under arecanut (Areca Nut Cultivation): 2.7 x 2.7 m (around 686 plants/ha)
Varieties
CPCRI hybrids VTL CH I and VTL CH II are the principal commercial planting materials, with reported yields of around 1.5-2.5 kg dry beans per tree per year under well-managed palm-based systems. Selected clones VTL 3 to VTL 30 are also distributed for region-specific plantings.
Pest and disease profile
The crop is susceptible to vascular streak dieback, black pod (Phytophthora spp.), tea mosquito bug and rats; CPCRI publishes specific spray schedules and sanitation guidelines for each.
Adoption and use
Beans are fermented, dried and sold to processors (Cadbury/Mondelez, Campco, Lotus Chocolate and others). The expansion of oil-palm under the NMEO-OP scheme has created additional opportunities for cocoa intercropping in Andhra Pradesh and Telangana. Cocoa thus serves as a stable secondary income for many smallholder palm growers.
