Abstract: The utilization of vermi-technology to reduce allelopathic effects is a cost-effective, efficient, and environmentally appropriate alternative to traditional chemical and mechanical methods. The current investigation was an effort to obtain vermicompost from C. erectus and its binary combination with soil and farmyard manure (FYM) using E. foetida . The pH, EC, organic carbon, macro and micro-nutrients, CO 2 emission, the average growth rate of the worms, number of worms, number of cocoons, and weight gained by earthworms were analyzed by standard methods. The present study also investigated the effect of produced vermicompost on the growth and yield of mung beans ( Vigna radiata L). The maximum reduction in soil pH was observed (6.47) in vermicompost of C. erectus leaves, among other treatments. The highest N (1.86%), P (0.15%), and K (0.41%) contents were found in the vermicompost of C. erectus leaves + FYM. Similarly, the maximum plant height (36.00 cm) was achieved in vermicompost of C. erectus leaves + FYM compared to other treatments. The highest SPAD value was observed (56.37) when the soil was treated with vermicompost ( C. erectus leaves + FYM) @ 5 t ha −1 , followed by the treatment where vermicompost ( C. erectus leaves + soil) @ 8 t ha −1 was applied. The soil amendment of vermicompost ( C. erectus leaves + FYM) @ 5 t ha −1 showed competitive results (in terms of the growth and yield parameters of mung beans) compared to other types of vermicompost and C. erectus biomass. This study has the potential to reduce the phytotoxicity of C. erectus biomass and transform it into a potent organic fertilizer through vermicomposting.
