Soil test based fertilizer prescriptions through integrated nutrient management using targeted yield approach for wheat in vertisols of Chhattisgarh


Author(s): Vedhika Sahu, LK Srivastava and VN Mishra

Abstract: To study the soil test based fertilizer prescription for wheat 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 wheat crop required 1.93 kg N, 0.52 kg P and 1.94 kg K to produce one quintal grain yield. Fertilizer and soil test efficiencies were estimated 31.49, 20.32 and 64.73 percent and 10.41, 48.08 and 5.48 percent respectively for N P K. The efficiency of FYM in terms of available nutrient was evaluated as 9.34, 4.86 and 4.06 percent respectively. On the basis these parameters, fertilizer N, P2O5 and K2O were derived for different targeted yield of wheat by using FYM as organic component in INM approach.
