To study the soil test based fertilizer prescription for SRI rice crop on grain yield, nutrient uptake and soil test data were used for obtaining basic parameters viz., nutrient requirement, contribution of nutrients from soil, fertilizer and organic manure. It was found that rice crop required 1.54 kg N, 0.28 kg P and 1.70 kg K to produce one quintal grain yield. Fertilizer and soil test efficiencies were estimated 40.17, 28.17 and 102.14 percent and 35.02, 82.55 and 17.24 percent respectively for N P K. The efficiency of FYM in terms of available nutrient was evaluated as 18.41, 6.27 and 10.79 percent respectively. On the basis these parameters, fertilizer N, P2O5 and K2O were derived for different targeted yield of rice by using FYM as organic component in INM approach.
