description Description

Mithila, the wetland rich region of north Bihar (India), provides an ideal hydro ecological niche for the cultivation of Euryale ferox Salisb. (Makhana). It is a spiny waterlily whose edible seeds underpin a centuries old agroindustry and cultural heritage. Vast network of ponds, oxbow lakes and dead river channels support dense macrophyte communities in which Makhana dominates alongside the species of Trapa, Nelumbo, Nymphaea etc. Although perennial, Makhana is cultivated as an annual crop in this area. Entire plants are destroyed during August–September to recover the buoyant seeds that settle to the pond beds, leaving nutrient rich detritus that favours the integrated aquaculture with detritivorous and airbreathing fishes. The life cycle of the crop spans four overlapping phases—seeding (Oct–Dec), seedling (Jan Mar), grand growth (Apr–Jun) and harvest (Jul–Sep) with flowering peaking during May and fruiting by midJune. Morphologically, the plant exhibits a unique mosaic of monocot and dicot traits and is evolutionarily significant within the family Nymphaeaceae. It can produce leaves up to 2.4m in diameter. Long valued as a ritual item, Makhana has reemerged as a “wonder food” in the postCOVID era owing to its low fat content, low glycemic index, resistant starch content, immuneboosting polyphenols and recently documented spermatogenic activity. It has been accorded Geographical Indication status during 2022 in the name of “Mithila Makhana”. Very recently dedicated Harmonized System of Nomenclature codes have been allotted to Makhana products. Announcement for setting up a “National Makhana Board” signals robust policy support for its production, processing and export. This communication highlights the botanical distinctiveness, nutraceutical significance and evolving export potentials of Makhana. It underscores the need for a balanced wetland management to reconcile the livelihood gains with secured ecological integrity.
