Wheat (Triticum aestivum L.) is an important agricultural crop growing throughout the world. Over the past few decades, fertilizer consumption in India has increased appreciably. Application of fertilizer nutrients by the farmer without knowing the soil fertility status and nutrient requirements of the crop affects soil quality and production crops adversely. Therefore, the aim of the study is to improve wheat productivity through effective nutrient management strategies. The objective of nutrient management strategies was to achieve the required crop yield in an efficient, economical, and sustainable manner. An on-farm trial was conducted during the Rabi seasons of 2015-2016 and 2016-2017 at farmers’ fields in pre-selected ten locations of Muzaffarpur district in North Bihar, considering farmers as replication, in order to assess the fertilizer application based on soil testing for the yield of wheat (Triticum aestivum) in North Bihar, India. The experimental field had an average soil pH of 8.60, EC of 0.35 dSm-1, organic carbon of 0.63 percent, nitrogen of 221.33 kg ha-1, phosphorus of 51.71 kg ha-1 and potassium of 149.98 kg ha-1. The results revealed that nutrient management based on soil testing has a statistically significant impact on yield attributes, yield, and economics. The study also confirmed that soil test-based fertilizer application is not only effective in increasing wheat productivity but also in maintaining soil health and optimizing input costs. The highest grain yield of 34.66 and 30.08 q ha-1 was found significantly in the soil test-based fertilizer application compared to the Recommended Dose of Fertilizer (RDF) (N120-P60-K40) and Farmers Practice (FP); (30.08 q ha-1). The maximum net return (Rs. 27750 ha-1) and the B: C ratio (2.61) were found in the fertilizer application based on soil test relative to RDF (N120-P60-K40) and FP. Future research should focus on evaluating the long-term impact of soil test-based fertilizer (STBF) application on soil health, nutrient balance, and microbial activity across multiple cropping cycles.
