Abstract

Purpose In the present study, efect of earthworm-processed MSW was seen on biochemical, physiological, and yield responses of Abelmoschus esculentus L. Methods Plants were grown on diferent amendment ratios of municipal solid waste vermicompost (MSWVC). Pot experiments were conducted by mixing MSWVC at 0, 20, 40, 60, 80, and 100% ratios to the agricultural soil. Results An increase in photosynthetic rate and stomatal conductance of plants grown at 20 and 40% MSWVC amendment ratios was observed. Total chlorophyll, carotenoid, and protein contents also increased signifcantly in 20, 40, and 60% amendment ratios at 65 days after germination (DAG). Likewise, proline, peroxidase, and lipid peroxidation increased with increasing levels of MSWVC at both 45 and 65 DAG. Conclusion The study suggests that MSWVC could be used as organic amendment in soil depicted by good yield and antioxidative response of lady’s fnger (A. esculentus) at diferent amendments of MSWVC (up to 60% w/w ratios). Furthermore, agricultural utilization of MSWVC will help in managing dreadful efects of the burgeoning amount of organic solid waste.
