Necrosis in Aonla is mainly due to the deficiency of which nutrient?

✅Explanation:
Necrosis in Aonla (Indian gooseberry) is primarily caused by boron deficiency. Boron is a micronutrient that plays a crucial role in cell wall formation, cell division, and the transport of sugars within the plant. A deficiency of boron leads to the breakdown of cell walls, resulting in the death of plant tissues (necrosis). In Aonla, boron deficiency typically manifests as dieback of shoots, cracking of fruits, and internal necrosis of fruits.

• Why Other Options Are Incorrect:
b) Manganese: Manganese deficiency can cause chlorosis (yellowing of leaves) and other symptoms in Aonla.
c) Nitrogen: Nitrogen deficiency primarily leads to stunted growth and chlorosis.
d) Magnesium: Magnesium deficiency can cause interveinal chlorosis in Aonla.
