A field experiment was conducted to evaluate the impact of various combinations of soil, seed, and foliar application of micronutrients on content of N, P, K, Fe and Zn of durum wheat (Triticum durum) cultivated in Vertic ustochrepts soil. The study aimed to determine the most effective method and combination of micronutrient application for optimizing macro-and micronutrient dynamics in durum wheat under the specific agro-edaphic conditions of the study area. Among the treatments, the application of 120:60:00 NPK kg ha^-1 (RDF) + seed treatment with ZnO + 0.5% ZnSO₄ foliar spray (T₁₀) significantly enhanced nitrogen and zinc content in the grain. A significantly higher concentration of phosphorus, potassium, and sulphur in the grain was observed with the application of 120:60:00 NPK kg ha^-1 (RDF) + seed treatment with FeSO₄ and ZnO + 0.5% FeSO₄ foliar spray + 0.5% ZnSO₄ foliar spray (T₁₄). The significantly higher iron content in both grain and straw was recorded with application 120:60:00 NPK kg ha^-1 (RDF) + seed soaking with 1% FeSO₄ + 0.5% FeSO₄ foliar spray (T₆). In straw, treatment T₁₄ resulted in significantly higher nitrogen, phosphorus, and sulphur content, while T₆ recorded the higher iron content. The application of treatment T₁₀ (120:60:00 NPK kg ha^-1 (RDF) + seed treatment of ZnO + 0.5% ZnSO₄ foliar spray) recorded significantly higher zinc content in straw. These findings highlight the potential of integrated micronutrient management, particularly involving seed treatments and foliar sprays, to enhance nutrient content in both grain and straw of durum wheat.
