Peanut (Arachis hypogaea L.) cultivation in the Mediterranean region frequently faces abiotic stresses that limit yield. While the roles of iron and sulfur are well-documented, the synergistic effects of these nutrients with selenium, particularly under field conditions, remain a significant knowledge gap. This study aimed to elucidate the individual and combined effects of Fe, S, and Se applications on the pod yield and yield components of peanut, specifically addressing this gap. A two-year field study (2021 and 2022) was conducted in the Eastern Mediterranean of T & uuml;rkiye using a split-split-plot design with three replications. Treatments included Fe (0% and 3%) were placed in main plots, S (0, 40, 60 kg ha-1) in sub-plots, and Se (0, 20, 40 ppm) in sub-sub-plots. Results demonstrated that S application at 60 kg ha-1 significantly increased pod yield by approximately 15% compared to the control (0 kg S ha-1), achieving the highest yield of 488.32 kg da-1. Similarly, Se application at 20 and 40 ppm enhanced pod yield by an average of 12%, reaching 469.24 kg da-1. Notably, the combination treatments (Fe+S+Se) outperformed single applications, suggesting a crucial synergistic interaction for maximizing yield. These findings imply that tailored nutrient management combining Fe, S, and Se can be a viable strategy to enhance peanut productivity in similar Mediterranean climates. Future research should focus on the underlying physiological mechanisms, particularly the role of Se in antioxidant defense and nutrient uptake efficiency.
