Field experiment was conducted during kharif season of 2018 at the instructional farm of IGKV, Raipur to calibrate soil test, fertilizer dose and crop yield for hybrid rice under SRI method. Various basic parameters viz. nutrient requirement, Contribution of nutrients from soil, fertilizer and organic manure (FYM) were obtained. It was found that hybrid rice (var. IRH-103) required kg N, kg P and kg K to produce one quintal grain yield. The efficiencies of fertilizer and soil test in terms of available nutrients were estimated as , , percent and , , percent respectively for N, P and K. | Calibration of soil test, fertilizer dose and crop yield with and without FYM for Hybrid rice () under SRI in vertisol of Chhattisgarh Plain
