Site-Specific Nutrient Management of Wheat in Eastern India


The project aims to quantify the variation in soil nutrient supply in wheat areas in West Bengal and Jharkhand and develop a site-specific nutrient management approach that improves on common farm practice (FP).
In the second year, 19 farmer field trials were set up in the alluvial and red-lateritic soil zones of West Bengal and Jharkhand. The study compared nine treatments including omission plots for N, P, K, S, Zn, B, the FP, the soil test-based recommendation, and the complete NPK treatment of 140-70-100 kg N-P2O5-K2O/ha (SSNM) that also included required amounts of secondary and micronutrients.
