Abstract: Proper plant nutrition is essential for successful production of vegetable crops. Integrated supply of micronutrients with macronutrients in adequate amount and suitable proportions is one of the most important factors that control the plant growth and development. Micronutrients are usually required in minute quantities, nevertheless, are vital to the growth of plant. Judicious use of micronutrients is essential for vegetable cultivation to get maximum yield of high quality produce. Plant metabolism, nutrient regulation, chlorophyll synthesis, reproductive growth, flower retention, fruit and seed development etc., are such effective functions performed by various micronutrients. Micronutrients which are essential for all higher plants are boron (B), chlorine (Cl), copper (Cu), iron (Fe), zinc (Zn), manganese (Mn), molybdenum (Mo) and nickel (Ni). 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. Boron is associated with the carbohydrate metabolism and reproductive phase of the plants along with photosynthesis or enzymatic activities. Taking this into consideration, in the current review focus on major functions of micronutrients in vegetable production and also gives a brief overview of recent research findings related to role of micronutrients on vegetable production, which can contribute to a better understanding of the role of micronutrients in vegetable plants.
