Koraput Tribal Turmeric Farming Odisha

The indigenous turmeric cultivation system of Koraput district, Odisha practised by Kondh, Poroja, and Gadaba tribal farming communities produces several landrace varieties of high-curcumin turmeric including Lakadong-type local strains suited to the laterite hill soils of the Eastern Ghats, using traditional intercropping, minimal-input cultivation, and natural shade management. Koraput farmers grow turmeric as a monsoon crop interplanted with taro, sweet potato, and legume creepers in forest-margin gardens maintained under partial tree shade, which increases curcuminoid content compared to open-field monoculture. Harvested rhizomes are boiled in iron pots, dried on bamboo platforms in the sun, then polished by gentle tumbling in a cylindrical bamboo basket to produce the bright orange-yellow dried turmeric finger. Koraput district is one of the prime production zones for high-curcumin organic turmeric exported to European spice buyers, and the Odisha State Cooperative Marketing Federation supports procurement from tribal growers at minimum support price.
