Soil test crop response (STCR) study was carried in Inceptisols of Bastar, Chhattisgarh during 2012-13 to formulate fertilizer recommendation with integrated nutrient management (INM) for hybrid maize. The experiment was laid out as per protocall of STCR. Gradient with respect to soil P was observed clearly but N and K variations were marginal. Good responses to fertilizer N and P were observed but K did not respond markedly. Larger proportion of variation in grain yields was accounted for N alone; however, its quadratic term gave better fit into the data as evidence from the higher R2 value (0.75) with curvilinear equation. Fertilizer N application with P and FYM could explain more grain yields variation than fertilizer alone or with other combinations. This relation showed better efficiency of fertilizer N and P with FYM application. A close and almost linear relationship was found between crop yields and nutrient uptake. Soil test efficiencies for N and K were recorded less than fertilizer sources and reverse trend was seen in case of soil test P. For calibrating and formulating fertilizer recommendations, basic parameters were recorded. The nutrient requirement (NR)- 1.65, 0.31 and 1.83 kg q-1; contribution from soil (CS)- 24.3, 71.9 and 27.3 percent; contribution from fertilizer (CF)- 16, 31.1, and 123.6 percent and contribution from FYM (CFYM)- 14.4, 7.5, and 11.9 percent for N, P and K, respectively. With the help of basic data, regression models and ready reckoner were developed which is useful for similar agro-ecology and cropping practices.
