Abstract:
The investigation was under taken during kharif season 2017 and 2018 at Instruction Farm, Indira Gandhi Krishi Vishwavidhyalaya, Raipur (Chhattisgarh) for study the soil test based fertilizer prescription for Hybrid Rice crop on the basis of grain yield, nutrient uptake and soil test data which were used for obtaining basic parameters viz., nutrient requirement, contribution of nutrients from soil, fertilizer and organic manure. It was found that Hybrid rice crop required 1.57 kg N, 0.32 kg P and 1.72 kg K to produce one quintal grain yield. Fertilizer and soil test efficiencies were estimated 41.41, 32.00 and 100.39 percent and 30.44, 72.84 and 15.37 percent, respectively for N, P and K. The efficiency of FYM in terms of available nutrient was evaluated as 13.02, 6.98 and 11.16 percent, respectively for N, P and K. On the basis these parameters, fertilizer N, P2O5 and K2O were derived for different targeted yield of Hybrid Rice by using FYM as organic component in INM approach.
