Sunflower (Helianthus annuus L.) is a globally significant oilseed crop, and nitrogen (N) is a crucial nutrient influencing its growth, yield, and oil quality. This study aimed to investigate the effects of different nitrogen sources on sunflower production. A field experiment was conducted using a randomized complete block design with various nitrogen treatments, including conventional fertilizers, organic sources, and Inorganic. Agronomic parameters such as plant height, leaf area index, and yield components were evaluated, along with oil content. Statistical analysis revealed significant differences among nitrogen treatments for various parameters. Organic nitrogen sources exhibited comparable performance to conventional Inorganic in promoting sunflower growth and yield, highlighting their potential as sustainable alternatives. Inorganic also showed promising results, particularly in enhancing nutrient uptake and soil health. These findings provide valuable insights into optimizing nitrogen management practices for sustainable sunflower production, contributing to enhanced productivity and environmental sustainability in oilseed cropping systems. Further research is warranted to elucidate the mechanisms underlying nitrogen source effects on sunflower physiology and to refine nitrogen management strategies for optimal crop performance and resource efficiency.
