Question

Water use efficiency is

• A. Total water required during crop growth period
• B. Production per unit water applied
• C. Duration of water applied during the crop growth period
• D. Yield of crop per hectare

Hint:

Water Use Efficiency (WUE) is expressed in units of \( \text{kg/ha-mm} \) or \( \text{kg/m}^3 \).
C4 crops (like sorghum and maize) generally have higher water use efficiency than C3 crops (like wheat and rice).
