Attempt was made on “Effect of integrated application of organic and inorganic fertilizer on sugarcane productivity and soil health” at Central Sugarcane Research Station Padegaon, Phaltan, Satara, Maharashtra during 2014-15 to 2016-17 to develop nutrient management strategy for sustaining soil health and sugarcane production during Suru season. The treatment receiving RDF as per soil test along with 20 t ha-1 FYM recorded significantly the highest canes yield, CCS yield and number of milleable cane (157.06 t ha-1, 21.57 t ha-1 and 89.92 ‘000 ha-1, respectively). The quality parameters were found non-significant. The soil pH was slightly reduced in all the integrated nutrient management treatments and the soil EC was increased in all the treatments over the initial. Soil organic carbon content was increased in all the integrated nutrient management treatments over the initial status. The treatment receiving RDF as per soil test along with 20 t ha-1 FYM was recorded significantly the highest organic carbon (0.77 %), available nitrogen (283.41 kg ha-1) phosphorus (26.32 kg ha-1) and potassium (303.94 kg ha-1). The application of RDF as per soil test along with 20 t ha-1 FYM recorded significantly the highest gross monetary returns (Rs.3,53,390 ha-1), and followed by RDF as per soil test along with 10 t ha-1 FYM + biofertilizers (Rs.3,44,393 ha-1). The highest benefit-cost ratio was reported in treatment having only RDF as per soil test (2.59). The application of recommended dose of fertilizers as per soil test along with 20 t ha-1 FYM for sugarcane and its two successive ratoon were found beneficial in terms of yield and soil health
