Think Extraordinary · Accepted Answer

Correct Answer: Option A. WUE = Crop Yield (Y) / Evapotranspiration (ET). Explanation: Water Use Efficiency is defined as the ratio of economic crop yield (Y) produced per unit volume of water consumed through evapotranspiration (ET): WUE = Y / ET (expressed in kg/ha-mm).

Answer

Option B: WUE = ET / Yield

Answer
