Sprinkler irrigation efficiency is typically:
A~30%
B60-80% (higher than surface; lower than drip)
C100%
D10%
Answer & Solution
Correct answer: B. 60-80% (higher than surface; lower than drip)
Application efficiency: drip irrigation ~80-95% (most efficient, water at root zone). Sprinkler ~60-80%. Surface (flood/furrow) ~40-60%. Lower efficiency = more water wasted (deep percolation, evaporation, runoff). Drip & sprinkler save water vs flood; encouraged in water-scarce areas.
