Abstract
Applications of synthetic chemical fertilizers and pesticides lead to several environmental hazards, causing damages to entire ecosystem. To reduce damage caused by such chemical inputs in agriculture and environment required a serious attention for replacement of chemicals input with eco-friendly options. In this study decaying macrophytes were selected as an option for organic agriculture, by analyzing its ability to provide important mineral nutrient to the maize crop grown in low nutrient soil as well as for providing resistant towards many common phyto-pathogens to enhance yield. The results of the study showed that decaying macrophytes have high concentration of stored important mineral nutrient in their body mass, which get released in the soil during its decay and to be used by the maize plant. The decaying macrophytes leaf extract have considerable amount of phenolic and flavonoids also having antimicrobial activity. The antimicrobial activity of the leaf extract has been analyzed against the common phyto-pathogen Pseudomonas aeruginosa , and S. aureus by agar disc method and the formation of clear zone indicate its potential as bio-control agent. So under intensive agricultural practices, application of such biological waste is of particular importance for enhancing soil fertility without chemical input, to ensure sustainable agriculture.Keywords
