INFLUENCE OF IRON FOLIAR FEEDING ON SOME GROWTH AND PHYSIOLOGICAL PARAMETERS OF WHEAT

Abstract

Micronutrients consist of six essential elements: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B) and molybdenum (Mo). These elements present in very small amounts in both soils and plants, but their role is regularly as important as the primary or secondary nutrients. They are playing and important function in growth and development of plant. Foliar fertilization of micronutrients is one of the most important methods of fertilizer application in agriculture practices in order to increase Fe concentration in grain since foliar nutrients help easy and fast consumption of nutrients by penetrating the stomata or leaf cuticle and enter the cells. Foliar application of iron, either single or along with other micronutrients can help achieve favorable results on growth parameters, yield components and yield quality of wheat crop. It is evident that foliar and soil application of Fe deficient soils enhance plant growth, yield quantity and quality, yield components and grain Fe concentration. The available literature on biofortification of wheat with Fe through foliar and soil application of Fe fertilizers on the growth parameters, yield components yield quantity and quality of wheat are reviewed and presented below.
