An Overview on Role of Micronutrients in Vegetable Production

The nutrients which are required in small quantities are called as micronutrients. Micronutrients are equally important as macronutrients for enhancing growth, yield and quality of plants. Micronutrients perform various functions, such as plant metabolism, nutrient regulation, chlorophyll synthesis, reproductive growth, flower retention, fruit and seed development. Micronutrients, which are essential for all higher plants, are iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), nickel (Ni) and chlorine (Cl). Micronutrients like Cl, Cu, Fe and Mn are involved in various photosynthetic processes and Zn, Cu, Fe and Mn are associated with various enzymatic activities, Mo is specific for nitrate reductase only. This study investigated the characteristics of micronutrients, their roles in the growth and development of plants and crops as well as the prevalent micronutrient deficiencies found in vegetable crops. Additionally, the study emphasizes the impact of micronutrients on vegetable quality which includes improved nutritional value and bioactive compounds. Concerns regarding the sustainable and effective use of micronutrients, along with future research goals are analyzed, including practical implications and recommendations for micronutrient management systems. Taking this into consideration, the current review focuses on the role of micronutrients in improving the quality of vegetables, as well as the possible impact of further research on this topic.
