The Efficacy of Micronutrient Fertilizers on the Yield Formulation and Quality of Wheat Grains

Abstract

Under the changing climatic conditions, one of the most pressing issues in wheat production is the improvement of the yield quality, the lack of which has a negative impact on animal and human health. More than 25% of the world’s population are affected by micronutrient deficiencies in food products, a problem which is known as hidden hunger. Thus, effective micronutrient management is crucial for improving both the quantity and quality of wheat production by increasing the plant’s ability to tolerate various environmental stresses and diseases. In this review, previous works were assessed to investigate the significance of micronutrient fertilizers and their interaction effects on the wheat grain yield and quality, including high-quality and nutritionally rich products. The application of micronutrients mixed with macronutrients significantly increases plant growth, physiological traits, yield components, the grain yield, and the quality traits. Among the types of applications, the foliar application of nutrients is very profitable due to its efficiency in terms of economics, ecology, and the qualitative and quantitative yield. In short, in-depth studies are needed to determine the best concentrations, forms, and times of application of micro-fertilizers to the wheat field and to mitigate the challenges of the increasing wheat demand due to steadily rising world population growth and reducing the rates of nutritional deficiency.
