A field experiment was conducted at new orchard, Department of Horticulture, University of Agricultural Sciences, Dharwad during 2014-15 and 2015-16 on “Integrated nutrient management studies in banana cv. Grand Naine (AAA)” through application of different combination of organic manures and inorganic fertilizers with green manure, Azospirillum and PSB. The results revealed that, vermicompost equivalent to 40 % RDN (24.20 t/ha) + Urea equivalent to 40 % RDN (535.73 kg/ ha) + Green manure (sunnhemp @ 8.88 t/ha) and Azospirillum (@ 30.86 kg/ha) equivalent to 20 % RDN + PSB (@ 30.86 kg/ha) (T7) recorded the highest yield parameters {bunch weight (26.94 kg), number of hands per bunch (11.75), finger weight (137.38 g), finger length (17.75 cm), plot yield (85.57 kg) and the yield per ha (66.02 t)}, gross returns (Rs.4.97 lakh/ha) and moderate net returns (Rs.3.04 lakh/ha) followed by T10 (Agrigold combination) and T11 (Bhumilabh combination) treatments. After the completion of the experiment the organic carbon was found to increase in organic treatments (T1 to T5) from 0.65 % to 0.72 %, whereas it was decreased from 0.65 % to 0.57 % in integrated treatments (T6 to T12). The available nitrogen and potash was significantly higher in organic treatments than integrated treatments whereas the available phosphorous was decreased in organic treatments compared to integrated treatments.
