Abstract: To increase the nutritional value of food crops and their endurance to water shortage circumstances, agronomic biofortification with zinc (Zn) and (Fe) may be used. Wheat (Triticum aestivum L.) is an important cereal crop that provides sample nutritious calories for humans and animals. Foliar application of fertilizers can guarantee nutrient availability to wheat, leading to higher yield and seed quality. However, limited research has been undertaken to understand the response of foliar application of Zn and Fe on wheat in Kanpur. The experiment was laid out in Factorial Randomized block design replicated thrice with eighteen treatments which combination with zinc and iron forms of fertilizers. A field trial was conducted to investigate the effect of Zn (0, 1.0, and 2.0 %), Iron (0, 0.5, 1.0%) and combined zinc and Iron foliar fertilizer application on two improved Wheat (Triticum aestivum L.) varieties locally referred to as K-1317 and K-1616 agro-ecological zones of Kanpur during the 2021-22 and 2022-23 (Cropping seasons).Foliar fertilization will be applied at the tillering, booting and earing stages while control plots were sprayed with tap water. There was significant effect of micronutrient application of Plant Height, Chlorophyll Intensity, and number of grains per spike, 1000-grain weight, straw yield and biological yield. The results were showed that combined foliar application of ZnSO4 and FeSO4 with the combine doses Zn1.0% × Fe0.5% expressed the highest growth and yield attributing characters. In conclusion, foliar application of micronutrient may be helpful to improve the yield and reduces micronutrient deficiency (Hidden Hunger).
