Tomato consists of nutrition and antioxidant like lycopene which avoids cancer. Nutrient deficiency occurs when the plant doesn’t get enough nutrients like Nitrogen, Phosphorus, Calcium, and so on, causing a severe reduction in production. In this review, the nutrient deficiency symptoms and their effects on the tomato plant are included. The tomato plant requires mainly three primary nutrients, i.e., Nitrogen, Phosphorus, and Potassium, in the highest quantity. The nutrient deficiency in tomatoes can be noticed by observing the symptoms like stunted growth, curling down of young leaves, tip burn, abnormal green foliage, and chlorotic lesions on the leaf margin. Due to nitrogen deficiency, uniform yellowing of leaves occurs, causing Chlorosis. Phosphorus deficiency slows down the development of plants along with the development of anthocyanin gathering. Potassium deficiency causes slow growth on leaves along with less photosynthesis. Blossom end rot causes by Calcium while root cracking occur by Boron and Zinc occur rosette. Some of the external factors contributing to nutrient deficiency are excessive soil moisture; microbial activity; high salinity especially in Ca, so it is suggested that the nutrient level should be maintain by applying nutrient containing compound. Some of them are managed by below management practices also. Further studies require to know the causes of these nutrient deficiency in tomato plant.
