This research explores precision fertilization techniques to enhance jute production in Katihar district, Bihar, crucial for small farming households in the Seemanchal region, aiming to replace indiscriminate nitrogen application with the Soil Test Targeted Yield (ST-TY) method, crucial for the economic and environmental value of jute, known as the "golden fiber." Over two years (2019-2020) in the Seemanchal region's Katihar district, an experiment compared Soil Test Targeted Yield (ST-TY) method with traditional practices, revealing minimal impact on soil properties but significant decreases in available nitrogen and phosphorus levels raising concern over nutrient management. Notably, achieving a targeted fiber yield of 32.52 qha-1 through specific fertilizer applications (83:35:19 N:P:K kg/ha) with organic matter consistently outperformed other methods. The method resulted in superior plant growth (385 cm) and fiber production (32.52 q ha-1), yielding the highest net income (96884 Rs ha-1) and benefit-cost ratio (3.44), showcasing its economic viability. This underscores the importance of tailored fertilizer strategies and organic materials for enhancing jute cultivation, suggesting broader adoption potential in Seemanchal and beyond.
