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

Surface irrigation is the least efficient, followed by sprinkler, then drip, with pitcher pot being the most efficient due to localized delivery of water.

Answer 2

Comparative efficiency approach:
Typical field water-use efficiency values illustrate the ranking directly, surface (flood/furrow) irrigation is around 30-40% efficient because of heavy conveyance and deep-percolation losses; sprinkler irrigation improves this to roughly 50-70% by reducing conveyance loss but still loses water to wind drift and evaporation; drip irrigation applies water directly to the root zone and reaches about 80-90% efficiency; pitcher-pot irrigation, being a fully localised, sub-surface, low-evaporation method, achieves the highest efficiency of all, often exceeding 90%. Ranking these values from lowest to highest gives Surface, Sprinkler, Drip, Pitcher pot.
