What are the symptoms of Borondeficiency and excess in plants

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.
