UPSC CSE 2025 (Prelims) CSAT Official Paper (25-May-2025)

Fox nuts (Euryale ferox), also known as Makhana, require shallow, stagnant freshwater bodies with clayey soil and adequate sunlight. They thrive in waterlogged areas with a moderate climate, minimal frost, and well-drained pond beds for root anchorage. The plant requires careful water management and periodic harvesting of seeds during the fruiting season.

In India, fox nuts are predominantly cultivated in Bihar, especially in districts like Darbhanga, Madhubani, and Purnia, which account for the majority of national production. Small-scale cultivation occurs in parts of Uttar Pradesh and West Bengal. Bihar’s wetlands and oxbow lakes of the Kosi and Gandak rivers provide ideal ecological conditions, supporting large-scale production. The crop holds socio-economic significance as a source of income for rural households and contributes to the local food economy.
