Bihar produces about 80–85% of India's makhana. The five-year 'Makhana Se Samriddhi Abhiyan' (2026–27 to 2030–31) aims to raise cultivation from 41,000 to 82,000 hectares and popped makhana output to 91,512 tonnes, with ₹89.79 crore set aside for 2026–27.
GI-tagged Mithila Makhana reached the US, Canada, Australia and Greece in 2026, including an 18-tonne sea shipment to Australia from Bihta. Income per hectare rose from ₹35,000 in 2012–13 to about ₹4.26 lakh in 2025–26. The state is working with APEDA on processing, branding and exports.
