Zinc (Zn) deficiency associated with low dietary intake is a well-documented public health problem, resulting in serious health and socioeconomic problems. Hence, there is an important and urgent need to increase the Zn concentration in edible parts of food crops. Recently, there has been much interest in the incorporation of organic molecules (sugars, amino acids, polysaccharides, etc.) or biostimulants into foliar fertilizers with the rationalization that these additives will enhance the uptake, or subsequent mobility of the applied nutrient. The goal of this research is to determine the factors that influence the efficacy of foliar applied inositol with the aim of increasing crop productivity and nutrient content of edible plant parts. The results show that foliar applied inositol plus Zn significantly increased Zn concentration in both leaves and grains compared to water and zinc sprayed controls. Here, we suggest that the formulation of the foliar applied Zn increases the mobility of Zn following its absorption by the leaf and accumulation in wheat grains.
