Abstract:

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 1.57 kg N, 0.32 kg P and 1.71 kg K to produce one quintal grain yield. The efficiencies of fertilizer and soil test in terms of available nutrients were estimated as 32.66, 73.38, 16.39 percent and 39.87, 30.53, 94.53 percent respectively for N, P and K. The efficiency of FYM was evaluated as 13.01, 5.43 and 10.10 percent for N, P and K respectively. Fertilizer adjustment equations were evolved for SRI rice crop to achieve a definite yield target based on the basic parameters viz. nutrient requirement, efficiencies of fertilizer, soil test and organic source (FYM). The ready reckoners for rice with the use of 5 tones of FYM were prepared for various yield targets by using the equation.
