Different Organic and Inorganic Sources of Plant Nutrients Influence Soil Health, Leading to Improve the Productivity and Profitability of a Fourteen‐Year Long‐Term Rice–Potato–Groundnut Cropping Pattern

This study aims to evaluate the impact of long‐term integrated nutrient management (INM) treatments on soil properties, crop productivity and the soil quality index (SQI) in scented rice–potato–groundnut cropping system. A comprehensive evaluation of soil quality indicators was carried out using four different SQI calculation methods: linear additive (SQI LA ), nonlinear additive (SQI NLA ), linear weighting (SQI LW ) and nonlinear weighting (SQI NLW ). Among all the treatments, the INM approach ( T 1 ), which combines 50% recommended NPK from inorganic fertilizer with 50% N from FYM, resulted in the maximum yield for all three crops. Within the organic nutrient management treatments ( T 2 – T 5 ), treatment T 5 , which involved 33%…
