Salvinia cucullata L. is an aquatic plant which is actively growing biomass and also easily available. In this study Salvinia cucullata biomass has been utilised to show the impact on Vigna unguiculata L. This experiment was conducted to find out the effect of biomass on germination, growth and biochemical parameters. The seeds of groundnut were germinated in six different concentrations of added biomass having 0-100 mg/l of biomass. It was observed that seedling vigour index, metal tolerance indices were increased and the percentage of phytotoxicity were decreased. The pot culture experiment revealed that, the growth parameters were found to be increased with increase in concentration of biomass and seedlings showed better result in terms of growth in at 10th, 20thand 30thdays thereby indicating that it had stimulating effect on the seedling growth. Similarly the total chlorophyll content, total soluble protein content were increased but free proline content was decreased with increase in concentration of biomass at 10th, 20th,30th and 100th days after treatment. So, it could be concluded that Salvinia biomass had an inducing effect on plant growth and it can be further utilised as biofertilizer.
