Biochemical, physiological, and yield responses of lady’s fnger (Abelmoschus esculentus L.) grown on varying ratios of municipal solid waste vermicompost

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 ۰, ۲۰, ۴۰, ۶۰, ۸۰, and ۱۰۰% ratios to the agricultural soil. Results An increase in photosynthetic rate and stomatal conductance of plants grown at ۲۰ and ۴۰% MSWVC amendment ratios was observed. Total chlorophyll, carotenoid, and protein contents also increased signifcantly in ۲۰, ۴۰, and ۶۰% amendment ratios at ۶۵ days after germination (DAG). Likewise, proline, peroxidase, and lipid peroxidation increased with increasing levels of MSWVC at both ۴۵ and ۶۵ 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 ۶۰% w/w ratios). Furthermore, agricultural utilization of MSWVC will help in managing dreadful efects of the burgeoning amount of organic solid waste.
