Question

Match List-I with List-II. List-I Critical stage for irrigation: A. Crown root initiation and flowering, B. Sprouting and tuberization, C. Tasseling and silking, D. Flowering and pod development. List-II Crop: I. Potato, II. Maize, III. Groundnut, IV. Wheat.

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

Hint:

Maize is highly sensitive to moisture stress at tasseling and silking stages.

Answer 1

The Correct Option is B

Concept:
Critical irrigation stages are crop growth stages at which moisture stress causes severe yield reduction.

Step 1: Crown root initiation and flowering.
These are critical irrigation stages for wheat. \[ A\rightarrow IV \]

Step 2: Sprouting and tuberization.
Sprouting and tuberization are important stages for potato. \[ B\rightarrow I \]

Step 3: Tasseling and silking.
Tasseling and silking are critical stages for maize. \[ C\rightarrow II \]

Step 4: Flowering and pod development.
Flowering and pod development are critical stages for groundnut. \[ D\rightarrow III \] Therefore: \[ A-IV,\ B-I,\ C-II,\ D-III \] \[ \therefore \text{Correct Answer is (B)} \]
