Abstract: Wheat is one of most important crop in the world contributing up to 28% of the world edible dry matter and up to 60% of the daily calorie intake in several developing country. Nutritional deficiencies are serious problems of public health in developing countries. To increase the productivity and quality of wheat micronutrient plays an important role. This study was conducted to study the effect of combined Zn and Fe fertilizers as foliar fertilizers on wheat agronomic performance and grain yield quantity. A split-plots in a randomized complete block design with 3 replications was used and PASW Statistics 18 software was used for statistical analysis. Results showed that compared to control (0%Zn+0%Fe), net photosynthetic rate was increased with 100%Zn13, 100%Zn9.5 and 100%Zn5.5 at 45.28, 73.07 and 39.54% respectively while 20%Zn+60%Fe13 increased up to 37.75% at the early filling stage and 100%Zn9.5 by the increase of 29.99% otherwise Zn an Fe had no effect. Flag leaf area increase was observed with 20%Zn+80%Fe13, 20%Zn+80%Fe9.5, 20%Zn+80%Fe5.5 and 100%Fe9.5 at booting stage with 15.84, 15.32, 14.67 and 15.40% increase respectively, at early filling stage with 20%Zn+60%Fe9.5 by 36.25% increase and at late filling stage with 20%Zn+60%Fe13 increased by 25.73%. The stalks dry mass show a more significant effect at booting stage and little effect at early filling stage and no effect at late filling stage. The yield was only affected with 20%Zn+80%Fe13.The inference can be drawn that foliar application of combined Zn and Fe fertilizer can enhance the net photosynthetic rate, SPAD and flag leaf area of Nongda399 winter wheat.
