Abstract: Makhana (Eurale ferox Salsib.) is an important aquatic plant growing in mostly in northern part of Bihar & West Bengal. It is mostly grown in streams waterhole, lakes, land depression trenches and marshland, etc. The infestation of weed takes place rapidly in the initial stage of development of Makhana crop. Therefore, regular weeding is essentially required during the initial stage of establishment of the seeding. On account of luxurious vegetative growth of Makhana leaves. i.e., after 30-40 days of transplantation, the infestation level of weeds, however, starts getting reduced. Herbicide like paraquat and glyphosate are effectively used in aquatic weeds control. Cyperus difformis and Aeschynomene aspera were remarkably controlled by the application of organic cakes like neem (Azadiracta indica L.) and arandi (Ricinus communis L) in equal proportion and @2-3 ton ha-1after pulverized the soil with rotavator. Makhana is an important aquatic crop, has tremendous potential to support the livelihood of resource poor farmers of eastern region of country.
