The present study was conducted in the experimental plot at Main Agricultural Research Station (MARS), College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka during 2014-15 and 2015-16 on “Integrated nutrient management studies in banana cv. Grand Naine (AAA)”. Application of plants with combination of organic manures + Green manure and Azospirillum was carried out to assess the influence on growth, yield and soil properties of banana. The results indicated that combined application of plants with Vermicompost equivalent to 40 % RDN (24.20 t/ha) + 40 % RDN through chemical fertilizer (Urea 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 growth parameters [pseudostem height (205.05cm), pseudostem girth (27.47cm), number of leaves (16.00), leaf area (8.87m2), the least number of days taken for shooting (190.65) and total crop duration (318.89)], yield parameters {bunch weight (26.94 kg), number of hands per bunch (11.75), finger weight (137.38 g), finger length (17.75 cm) and the yield per ha (66.02 t)] followed by T10 and T11 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 N in soil was significantly higher in organic treatments than integrated treatments. The available phosphorous was decreased in organic treatments compared to integrated treatments. The available potash recorded higher status in organic treatments compared to integrated treatments.
