The soil test based nutrient man agent approaches provide principles and tools for supplying crop nutrients in scientific basis for balanced fertilization as and when needed by crop to achieve higher the yield. These approaches not specifically aim to either reduce or increase fertilizer use. Instead, they aim to apply nutrients at optimal rates and time to achieve higher yield and high efficiency of nutrient use by the crop, leading to more net returns per unit of fertilizer invested.

The soil test based nutrient man agent approaches provide principles and tools for supplying crop nutrients in scientific basis for balanced fertilization as and when needed by crop to achieve higher the yield. These approaches not specifically aim to either reduce or increase fertilizer use. Instead, they aim to apply nutrients at optimal rates and time to achieve higher yield and high efficiency of nutrient use by the crop, leading to more net returns per unit of fertilizer invested. With this background field experiments conducted to study the soil test based nutrient management approaches in dry direct seeded rice-mustard cropping system. Application of nutrients as per SSNM approach for targeted yield of 55 q ha-1 for Dry DSR registered significantly higher grain and straw yield (54.73 and 68.38 q ha-1, respectively) and residual mustard seed yield and stover yield (592 kg ha-1 and 1856 kg ha-1, respectively) over farmers practice and other soil test methods.
