Question: The new leaf of the plant shows yellow symptoms and the veins remain green caused by the deficiency of which nutrient? (IBPS AFO 2020)
Options:
Fe
Mn
N
S
This yellowing between the leaf veins while the veins stay green is called interveinal chlorosis. It's a classic symptom of manganese (Mn) deficiency in plants. Manganese is essential for chlorophyll production and photosynthesis.
📌Other Options Explanations:
-Option A: Fe (Iron) – Iron deficiency also causes interveinal chlorosis, but it usually appears on younger leaves first.
-Option C: N (Nitrogen) – Nitrogen deficiency causes overall yellowing of older leaves, starting at the tips.
-Option D: S (Sulfur) – Sulfur deficiency causes general yellowing of the whole plant, often resembling nitrogen deficiency.
-Option E: Ca (Calcium) – Calcium deficiency affects new growth, causing distorted or dead leaf tips.
