Question

Arrange the following in increasing order of Water Use Efficiency:
(A) Drip Irrigation
(B) Pitcher pot Irrigation
(C) Surface Irrigation
(D) Sprinkler Irrigation

• A. (A), (B), (C), (D)
• B. (D), (C), (B), (A)
• C. (B), (A), (D), (C)
• D. (C), (D), (A), (B)

Hint:

Water Use Efficiency: Surface < Sprinkler < Drip < Pitcher.

Answer 1

The Correct Option is D

Step 1: Surface irrigation has the highest losses, so it ranks lowest in efficiency.
Step 2: Sprinkler reduces conveyance loss but still loses water to evaporation and drift.
Step 3: Drip irrigation delivers water directly to roots, and pitcher pot irrigation is even more localised.
Step 4: The correct answer is \[ \boxed{\text{(C), (D), (A), (B)}} \]
