Abstract The investigation entitled, “Physio-chemical properties of soil as affected by integrated nutrient management in rice-chickpea cropping sequence under south Gujarat condition” was conducted during kharif and rabi seasons of 2014–15 and 2015–16 at College Farm, Navsari Agricultural University, Navsari. The treatment consisted of integrated nutrient management viz., T1-100% RDN through FYM, T2-100% RDN through bio-compost, T3 50% RDN through FYM + 50% RDN through biocompost, T4-50% RDN through FYM + 50% RDN through inorganic fertilizers, T5-50% RDN through BC + 50% RDN through inorganic fertilizers and T6 100% RDN through inorganic fertilizers to rice in kharif season as main plot treatments replicated three times in randomized block design. During rabi season each main plot treatment was splited into three sub plot treatments with three levels of recommended dose of fertilizers viz.,-50% RDF, S2-75% RDF and S3-100% RDF toS1 chickpea resulting in eighteen treatment combinations replicated three times in split plot design. Application of 100% RDN through FYM recorded lowest values for bulk density. Treatment 50% RDN through FYM + 50% RDN through bio-compost recorded maximum values of available nitrogen, phosphorus and potassium in soil. Similarly, during rabi season the residual effect of 100% RDN through inorganic fertilizers applied to kharif rice showed that lowest bulk density value recorded with application of 100% RDN through FYM and significant improvement in soil with available NPK after harvest of chickpea recorded with 50% RDN through FYM + 50% RDN through bio-compost. In case of chickpea, 100% RDF recorded highest value for bulk density and available NPK during individual years of study as well as in pooled analysis.
