Abstract: A field experiment was carried out to assess the effect of integrated nutrient management on growth and yield of onion cv. Pusa Madhvi at Horticultural Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow, U.P. India during the year 2013-14. 10 treatments [RDF as control, FYM, Vermicompost, PSB, Azotobacter, Azosprillium, and combination with nitrogen, phosphorus and potash] were applied with three replications and laid out under Randomized Block Design. The results showed that the maximum plant height (74.32 cm), bulb diameter (4.60 cm), neck thickness (1.06 cm), bulb length (4.39 cm) and number of leaves (9.88) per plant were recorded under treatment T10 - RDF (50%) + Vermicompost (50%) at 90 (DAT). Whereas, the maximum leaf length (62.23 cm) was observed in the treatment T5 (Azotobacter @ 100%). Although, the treatment T showed the maximum bulb weight (175.67 g) but the maximum yield (283 q ha–1) and TSS (12.30 0B) were recorded in T . Thus, it can be concluded that treatment T i.e. application of RDF (50%) + Vermicompost (50%) was suitable for better growth and higher production of onion cv. Pusa Madhvi under Lucknow condition having high soil pH of 8.2.
