Pot experiment was conducted to assess the performance of live earthworms and vermicompost on growth and yield of lady's finger (Abelmoschus esculentus). Among the various treatments, live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertiliser and control were organised. The results indicated that all growth and yield parameters were found superior and significantly higher (bud initiation – 30 days, flower formation – 36 days, number of buds and flowers – 50 and 47, number of fruits – 225, maximum weight of fruit – 70 g, maximum length of fruit – 23.87 cm) in the pots with live earthworms at the 5% level. Results obtained by earthworm application were best followed by results of vermicompost application.
