PURPOSE: The present investigation was carried out with the assumption that aquatic weed, mostly macrophytes, that is considered as problematic aquatic component can be turned to a money gyrostat through its commercial exploitation that includes composting and pelleting. METHODS: So in present investigation the aquatic problematic macrophytes (APM) were biologically converted to vermicompost and ‘enriched dispersible multipurpose vermipellets’ through vermitechnology. RESULTS: The ratio (37.5:1) of aquatic problematic weed/macrophytes and pure vermiculture (PVC) for getting higher return (416% for vermipellets and 414% for vermicompost) on investment was standardized. Quality aspects and economic returns from both vermicompost and vermipellets were worked out. CONCLUSION: Bioconversion of APM to vermipellets gave more return on per unit investment. The quality (that includes- C/N ratio, weed and disease resistant, nutrient composition and dispersible nature) of the vermipellets were better in comparison to vermicompost. The empirical models for predicting C/N ratio on the basis of quantity of APM for both vermicompost and vermipellets have been developed exclusively.
