In the process of plant production, micronutrients are considered as one of the important factors for both plant growth and development. Foliar feeding of micronutrients is an important method for the crops to enhance their productivity as well as profitability by increasing the concentration of zinc in the grain. But due to narrow knowledge about the zinc-based foliar fertilizers limits the utilization, distribution, specification and mobility of zinc inside the leaves of the plant. Wheat crop during its growth stages is very responsive to the micronutrient application. Due to this response, it has more potential to increase productivity in terms of grain yield. The content of zinc can also be increased when zinc is provided to the plant in the form of foliar application. This element has the utmost importance in the plant’s overall metabolism and also their physiology as it enhances many physiological and biochemical reactions inside the plants. The application of zinc in the foliar feeding not only elevates the deficiency of zinc but also enriches the grain quality when provided at a proper time for increasing its application efficiency. Both the yield as well as traits associated with the yield are also increased through zinc foliar feeding. On the other hand, polyamines (particularly putrescine) posses the two of more than two amino acids having low molecular weights and also aliphatic nitrogenous base. They are mainly available within all cells and are characterized through the products in the metabolic processes by the living organisms. Sometimes, they are also known to be behaving like a bio-stimulant as they are not only involved in general growth and developmental processes but also in responding to the abiotic stresses. This review mainly focuses on how zinc and polyamines (PAs) especially putrescine (Put) affects wheat productivity.
