Plant nutrient deficiency is the most serious problem in agriculture, particularly in vegetable cultivation. This results in lower crop yield and quality, which reduces the farmer's income. However, malnutrition arises as a result of the consumption of vegetables that are lacking of vital nutrients, resulting in around 1.7 million deaths every year. Eating nutrient-dense vegetables is the most cost-effective strategy to combat malnutrition. Malnutrition is major issue in the world and more than 60% of people are affected by iron, 30% zinc, 30% iodine, and 15% selenium. It is necessary to provide crops with micronutrients and macronutrients essential for plant growth in order to avoid malnutrition and hidden hunger in humans and yield loss in vegetables. The efficiency of inorganic micronutrients applied to soils is low as they become easily fixed to soil particles. Hence, applying a foliar spray of nutrients is an effective option to enhance plant nutrient use efficiency. In this review, we discussed about importance of nutrients in vegetable production and human health. Further, we make clear about importance of vegetables to overcome malnutrition, how to develop nutrient-rich vegetables, and finally how to plant response to applied nutrients.
