A review on management of Hydrilla verticillata and its utilization as potential nitrogen-rich biomass for compost or biogas production

Abstract

Hydrilla verticillata, an invasive aquatic weed is found to be a complex worldwide. Chemical and biological treatments can be applied for its growth retardation, but it may affect the quality of water, ultimately affecting aquatic lives. Previously reported studies proposed that the H. verticillata can be managed and utilized using advanced techniques that changed the approach towards it from nuisance to useful resource. It has been proved to be protein-rich and hence can be used as fodder for cattle. Exploring the feasibility of H. verticillata has become prime importance in any of the application of it. However, there is a need to research on large-scale management and utilization of H. verticillata to benefit the agriculture field. This paper provides a summary of growth, harvest and recent development for the management and use of H. verticillata. Based on the present scenario, possible forthcomings are discussed.
