A field study was undertaken at College of Horticulture, Anantharajupet during the years 2012 – 2013 to investigate the possible effects of inorganic nutrients in combination of organic manures (Farmyard manure and Vermicompost) concomitant with biofertilizers viz., Azospirillum, Phosphate Solubilizing Bacteria (PSB) and Frateuria aurantia (FA) applied at different levels of concentrations. The results showed that highest plant height (129.67 cm) at 3 MAP (months after planting) and 5 MAP (184.29 cm), pseudostem girth at 3 MAP (35.61 cm) and 5 MAP (49.74 cm), higher nitrogen concentration in index leaf at 3 MAP (2.93 %) and 5 MAP (3.28 %), phosphorus content at 3 MAP (0.26 %) and 5 MAP (0.24 %) and potassium content at 5 MAP (3.54 %) were apparent with application of 80 % RDF (inorganic nutrients) viz., Nitrogen (43.4 g), Phosphorus (40 g) and Potassium (33.3 g) plant-1 in combination of organic manures i.e. 20 % RDN (Vermicompost @ 4.285 kg plant-1) along with biofertilizers (Azospirillum, PSB @ 50 g plant-1 and FA @ 25 g plant-1) while application of 80 % RDF (inorganic nutrients) viz., Nitrogen (43.4 g), Phosphorus (40 g) and Potassium (33.3 g) plant-1 in combination of organic manures i.e. 20 % RDN (Farmyard manure @ 5.309 kg plant-1) along with biofertilizers (Azospirillum, PSB @ 50 g plant-1 and FA @ 25 g plant-1) has registered maximum retention of functional leaves at 3 MAP (10.58) and shooting (15.75) concomitant with highest leaf area (3.87 m2) at 3 MAP, higher nitrogen (2.88 %) and phosphorus contents (0.24 %) in index leaves at shooting stages along with highest potassium content (3.25 %) at 3 MAP and shooting (3.42 %). From this study, it can be inferred that both treatments i.e. 80 % RDF (inorganic nutrients) viz., Nitrogen (43.4 g), Phosphorus (40 g) and Potassium (33.3 g) plant-1 in combination of organic manures i.e. 20 % RDN (Vermicompost @ 4.285 kg plant-1) along with biofertilizers (Azospirillum, PSB @ 50 g plant-1 and FA @ 25 g plant-1) and 80 % RDF (inorganic nutrients) viz., Nitrogen (43.4 g), Phosphorus (40 g) and Potassium (33.3 g) plant-1 in combination of organic manures i.e. 20 % RDN (Farmyard manure @ 5.309 kg plant-1) along with biofertilizers (Azospirillum, PSB @ 50 g plant-1 and FA @ 25 g plant-1) were involved in improving growth and leaf nutrient concentrations in banana at different growth stages of plant life.
