Author(s): GK Jatav, LK Srivastava and Rakesh Banwasi
Abstract: The investigation was under taken during Kharif season 2019 and 2020 at Research Farm, Indira Gandhi Krishi Vishwavidhyalaya, Raipur (Chhattisgarh) for study the soil test-based fertilizer prescription for 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 rice crop required 1.55 kg N, 0.30 kg P and 1.85 kg K to produce one quintal grain yield. Fertilizer and soil test efficiencies were 31.65, 20.76 and 116.71 percent and 23.82, 57.42 and 11.24 percent, respectively for N, P and K. The efficiency of FYM in terms of available nutrient was evaluated as 9.56, 6.38 and 8.84 percent, respectively for N, P and K. On the basis these parameters, fertilizer prescriptions were derived for different targeted yield of Rice by using FYM as organic component in INM approach for N, P2O5 and K2O.
