The experiment was laid out in split plot design with two replications. The main treatments were aquatic weed vermicompost, banana pseudostem vermicompost and farmyard manure along with vermiwash through soil application, foliar application, soil + foliar application and control treatment as water spray. The subplot treatments consisted of AMF application and without AMF application. Taller plants were observed in banana pseudostem vermicompost and aquatic weed vermicompost treated plots. Significantly higher number of leaves with high leaf area index and dry matter production was noticed in aquatic weed vermicompost compared to other organic manures. Days for 50 per cent flowering was found maximum for farmyard manure. Aquatic weed vermicompost also showed better root characteristics along with yield attributes such as number of flowers plant-1, number of fruits plant-1, fruit yield plant-1, total fruit yield ha-1, number of seeds fruit-1 & seed yield ha–1 with better seed quality parameters like seed viability, seeding vigour and germination percentage. Among the modes of vermiwash application, soil + foliar application of vermiwash was found better in showing superior trends in plant height, number of leaves, leaf area index, dry matter production, number of flowers and fruits plant-1, fruit yield plant-1, total fruit yield and seed yield ha–1 with better seed quality i.e., seedling vigour and germination percentage. AMF application also showed maximum plant height, leaf area index, dry matter production, root length, root - shoot ratio, fruit yield plant-1, total fruit yield, weight of seeds fruit-1 and seed yield ha–1. Higher BC ratio was found in aquatic weed vermicompost, soil + foliar application of vermiwash and in AMF. So aquatic weed vermicompost along with soil + foliar application of vermiwash and AMF is ideal for quality seed production in bhindi.EnglishThesis
