Abstract: A field experiment was conducted during Rabi season 2016-17 to find out the effect of FYM and Vermi Compost with or without PSB and Azotobactor and rates of organic manures (50% and 100% RND) on growth attributes and yield parameters of onion (Agri found dark red) on a clay loam soil. The treatments comprised of organic, inorganic fertilizer and biofertilizers with ten treatments 100% RDF through inorganic, 100% RDF through FYM (N Basis), 100% RDF through vermicompost,50% RDF through Inorganic Fertilizers + 50 % through FYM, 50% RDF through Inorganic Fertilizers + 50 % through vermicompost, 5 0% RDF through Inorganic Fertilizers + 50 % through FYM + PSB, 50% RDF through Inorganic Fertilizers + 50 % through vermicompost + PSB, 50% RDF through Inorganic Fertilizers + 25 % vermicompost + PSB, 100% RDF through FYM (N Basis) + PSB + Azotobactor and 100% RDF through vermicompost + PSB + Azotobactor. Results revealed that the application of organic manure significantly influenced the plant height (cm), number of leaves, fresh weight of leaves (g plant-1) and dry weight of leaves (g plant-1), diameter of bulb (cm), bulb weight (g), bulb yield (q ha-1), total soluble solid (0B) and allyl propyl content (ppm) significantly increased with 100% RDF through Vermicompost + PSB + Azotobactor).were significantly influenced with 100% RDF through Vermicompost + PSB + Azotobactor at 30 and 60 days of transplanting. Application of 100% RDF applied through vermicompost + PSB + Azotobactor (T10) recorded maximum gross returns, net return and cost benefit ratio of onion crop.
