The present study was undertaken to find out the influence of different sources of organic manures (WG organic soil, organic grains, liquid organic manure and FYM) at different levels along with inorganic fertilizers on soil microbes and yield of banana cv. Grand Naine. Experiments were carried out at Agricultural Research Station, Tamil Nadu Agricultural University, Bhavanisagar during 2010-11 and 2011-12. The banana cv. Grand Naine (AAA) was used as a test crop. The experiments consisted of thirteen treatments viz., Control (100% Recommended dose of fertilizer), four treatments consisted of WG organic soil @ 20 and 40 per cent in combination with 100 and 75 per cent RDF, two treatments consisted of 2 per cent liquid organic manure spray on bunches along with 100 and 75 per cent RDF, four treatments consisted of WG organic grains @ 20 and 40 per cent combined with 100 and 75 per cent RDF and the last two treatments comprised of FYM @ 10kg plant-1 with 100 and 75 per cent RDF combinations. Experiments were laid out in Randomized Complete Block Design (RCBD) and treatments were replicated thrice. Study reveals that bacterial load in soil was significantly influenced through INM treatments during both the years of experiment. Among the treatments, application of 75 per cent RDF + FYM @ 10kg plant-1 recorded the maximum bacterial and fungal population in soil at different stages of banana growth except 3 month after planting. Actinomycetes population was also high under 75 per cent RDF along with either 40 per cent WG organic soil or 40 per cent WG organic grains. Soil organic carbon was also observed higher under this treatment when compared to chemical fertilizers. Hence, integrated nutrient management (75or 100% recommended dose of fertilizer coupled with either FYM @ 10kg plant-1/40% Wellgro soil or grain) practices has been found to be an ideal option to improve biological properties and soil organic carbon in banana under soil climatic conditions of Western zone of Tamil Nadu.
