Nitrogen fertilizers, though essential for crop productivity, exhibit low use efficiency (30-40%), resulting in environmental pollution and soil nutrient imbalances. Molybdenum (Mo), a critical micronutrient, plays a vital role in enhancing nitrogen use efficiency (NUE) by acting as a cofactor for key enzymes like nitrate reductase and nitrogenase, which facilitate nitrogen assimilation and fixation.  <br />This review highlights the significance of Mo supplementation in agriculture, particularly in improving crop yields, nitrogen uptake, and nutritional quality. Research indicates that optimal Mo application boosts chlorophyll synthesis, stress tolerance, and phosphorus uptake while reducing nitrate leaching. Crops such as wheat, rice, and chickpeas show substantial benefits from Mo application under varying soil conditions. However, Mo availability remains limited in acidic and sandy soils, necessitating targeted approaches. The findings underscore Mo's potential to improve NUE, reduce dependency on chemical fertilizers, and promote environmental sustainability. Further exploration of Mo, including advancements in nanotechnology, offers promising prospects for developing efficient, eco-friendly agricultural practices to address global food security challenges. https://jpoll.ut.ac.ir/article_105165_7d2d668f5dc12773efb98cc76dab9059.pdf
