Nowadays we are facing problems in agricultural production, whether in terms of productivity or quality. Therefore, we need to focus on what we can do to give plants some ability to growth and increase their productivity in quantity and quality. In this concern, Antioxidants have synergistic effects on growth and productivity of many species of plant. Antioxidants are the natural and safety compounds which inhibit oxidation that can produce free radicals. Foliar application with antioxidants helps agricultural crops to resist environmental stresses and restore their capacity, thus obtaining the highest possible yield. As well as, Nano-fertilizers are one of the applications of nanotechnology which are of great importance in agriculture to improve crop growth, quality and quality parameters while increasing the efficiency of food use, reducing fertilizer waste and the cost of agriculture. Nanomaterials provide more space for different metabolic reactions in the plant, which increases the rate of photosynthesis and produces more dry matter and yield productivity. Therefore, we can use these materials as a foliar spray on plants to achieve the greatest economic return.
