Quick Share

20 July 2023, New Delhi: Plants absorb various nutrients to grow. Any imbalance in nutrients may affect the final produce. Hence, a thorough examination of the growing plant can help in identifying particular nutrient stress. Typical signs may show up if a plant is deficient in a specific nutrient. A nutritional deficiency does not immediately result in symptoms. Instead, the regular plant processes are disturbed, leading to an overabundance of some intermediate organic molecules and a deficiency in others. This results in abnormalities that are later recognized as symptoms.

The growing tips of roots and leaves will turn brown and die. The edges of the leaves will look ragged as the edges of emerging leaves stick together. Fruit quality will be affected by the occurrence of blossom-end rot on fruits.


Plants may exhibit typical Mg deficiency symptoms, and when in high excess, K deficiency may also occur.
