Nutrients play an important role in improving productivity and quality of banana. It has been observed that the nutrient applied alone was less effective in improving banana production as compared to nutrients applied in combination with organic manures and biofertilizers. Keeping in view the conservation of soil health and quality production on a long-term basis, a field experiment was conducted during 2009–2011 to find out the influence of Integrated Nutrient Management of banana on leaf characteristics, growth and nutrient status of tissue cultured banana cv. ‘Grand Naine’. The study indicates that combination of inorganic fertilizers with organic manures, biofertilizers and bioagents significantly increased growth parameters, leaf characteristics, and leaf nutrient status of banana. The leaf characteristics in terms of functional leaves, total number of leaves, phyllochron, leaf area, and leaf area index were significantly influenced by the combination of inorganic fertilizers with different biofertilizers and organic manures. Similarly, leaf nutrient status like nitrogen, phosphorus pentoxide , (P ₂O ₅), potassium dioxide (K ₂O), and leaf relative water content were also influenced greatly by different nutrients. Treatment involving combination of 100% recommended dose of fertilizer (RDF) + arbuscular mycorrhizal fungi (AMF) + Azospirillum + Trichoderma harzianum showed overall superiority in most of the parameters.
