Effect of integrated nitrogen management on growth and yield of banana on Inceptisol soil was studied by conducting an experiment at Post Graduate Institute Farm of Mahatma Phule Agricultural University, Dist: Ahmednagar. An experiment was laid out with ten nitrogen substitution treatments through FYM, neem cake and vermicompost in different proportions (25%, 50% and equal nitrogen from these sources) replicated thrice in randomized block design. The recommended dose of banana as 200:40:200 g plant-1 with seven splits of nitrogen and basal application P2O5 and K2O at planting was carried out for this experiment. The number of functional leaves up to 180 DAP were not significantly influenced by integrated nitrogen management treatments but at later growth stages, substitution of nitrogen either @ 25 or 50 % through FYM recorded higher number of functional leaves throughout crop duration period. Application of 50% N: FYM + 50% N: RDF recorded significantly highest pseudostem height while substitution @ 25% N through FYM along with 75% N: RDF recorded significantly higher psedostem girth and leaf area index of banana. Nitrogen substation @ 25% either through FYM, neem cake or vermicompost induced early shooting (flowering) of banana by 14 to 18 days. However, application of 50% N: through neem cake + 50% N: RDF recorded significantly less duration from shooting to harvest or for bunch development of banana. Significantly higher yield of banana was recorded with the application of 25% N through FYM along with 75% N: RDF than rest of the treatments. The integrated nitrogen management treatment significantly influenced the banana yield. The nitrogen management as 25% N: FYM + 75% N: RDF reported significantly higher yield of banana (73.05 t ha-1) followed by 50% N: FYM + 50% N: RDF (69.55 t ha-1) and inorganic fertilizer application based on soil test (67.22 t ha-1), 50% N:VC + 50% N: RDF (67.04 t ha-1), 25% N:VC + 75% N: RDF (65.26 t ha-1), 25% N: NC + 75% N: RDF (50.44 t ha-1) and RDF (60.86 t ha-1).
