Question

Match List I with List II

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-II, B-I, C-III, D-IV
• C. A-I, B-II, C-III, D-IV
• D. A-II, B-I, C-IV, D-III

Hint:

Remember nutrient deficiency symptoms:
- N: Overall chlorosis (older leaves first)
- Zn: Rosetted growth (little leaf)
- Mo: N-like symptoms (young leaves)
- Fe: Interveinal chlorosis (young leaves)
Use the mnemonic: "N for Overall Yellow, Zn for Rosette, Mo for N-like, Fe for Interveinal."

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question tests knowledge of nutrient deficiency symptoms in plants.

Step 2: Detailed Explanation:
Nitrogen (A):
Deficiency causes overall chlorosis (II) - yellowing of entire plant, starting with older leaves.
Nitrogen is mobile and moves from older to newer leaves.
Thus, A matches with II.
Zinc (B):
Deficiency causes rosetted growth (I) - stunted growth with small leaves at stem ends.
- Little leaf disease in fruit crops.
Thus, B matches with I.
Molybdenum (C):
Deficiency causes symptoms similar to N deficiency (III) because Mo is required for nitrate reduction.
Symptoms appear first on young leaves.
Thus, C matches with III.
Iron (D):
Deficiency causes severe interveinal chlorosis (IV) - yellowing between veins while veins remain green.
Symptoms appear first on young leaves.
Thus, D matches with IV.

Step 3: Final Answer:
Thus, the correct matching is A-II, B-I, C-III, D-IV, which corresponds to option (B).
