- It is an aquatic plant, requiring ponds, shallow lakes, or waterlogged fields for cultivation.
- Fox nut fruit is a berry, large, round, spongy tree consisting of 20-25 small black seeds which are processed into the final edible product i.e. makhana.
- It is a labour-intensive crop.
Climatic conditions:
- Grows well in humid to sub-humid conditions with an air temperature of 20°C-35°C, relative humidity of 50-90%, and annual rainfall of 100-250 cm.
- It is an obligate self-pollinated, seed-propagated plant.
Traditional cultivation practices:
- Cultivation, collection, and puffing are hereditary traditional practices of the Mallah community in Bihar.
- These practices are passed down through generations and performed by experienced workers.
Cultivation cycle:
- Sown during the Kharif season, which coincides with the onset of the monsoon in India, typically from June to July. The monsoon rains provide the necessary water levels for the aquatic environment in which Makhana grows.
