Background: This study focuses on examining the impact of organic-inorganic nitrogen management and boron-sulfur nutrition on key growth and yield parameters of mustard to enhance crop productivity. By analyzing the effects of different treatments, the research seeks to provide insights into optimizing nutrient management strategies for improved agricultural practices and sustainable crop production in the region. Materials and Methods: The pre-experiment soil analysis was done to determine nutrient status. The field experiment utilized a split-plot design with three replications. The main plots was organic-inorganic nitrogen managements which contains four nitrogen rates (RDF, 75% urea/25% manure, 50% each, 25% urea/75% manure) with recommended P/K. The sub-plots were boron-sulfur nutrition including S1= 1kg B ha-1, 40kg S ha-1, and S2= 1kg B + 40kg S ha-1. Growth and yield parameters were recorded following standard procedures. Data was statistically analyzed by OPSTAT online using ANOVA to determine treatment effects. Findings: The study showed integrating organic manures to substitute 25-50% inorganic nitrogen significantly increased plant height, branching, and yields of mustard versus recommended fertilizer dose. Micronutrient supplementation with boron and sulfur also improved growth and productivity over control. Balanced organic-inorganic nitrogen management along with B and S nutrition had significantly positive effect on the all crop characteristics, increasing seed, stover and biological yields by 11-13% over sole inorganic fertilization. Conclusion: Balanced Integrated nutrient management is essential for optimal growth and productivity of mustard plants. Organic-inorganic nitrogen and boron-sulfur management significantly influenced plant height and crop productivity. Combining of Organic-inorganic nitrogen and boron-sulfur management can promote sustainability and reduce chemical fertilizer use.
