Field water used efficiency is calculated by
A. WUE = $$\frac{{\text{Y}}}{{{\text{WR}}}}$$
B. WUE = $$\frac{{\text{Y}}}{{{\text{ET}}}}$$
C. WUE = $$\frac{{\text{Y}}}{{{\text{CU}}}}$$
D. None of these
Answer: Option B
Solution (By Examveda Team)
The field water use efficiency (WUE) is the ratio between the dry matter production of a plant (the output) divided by evapotranspiration. Thus the equation for WUE is:WUE = $$\frac{{\text{Y}}}{{{\text{ET}}}}$$
Y = Dry matter production (Kilogram/hectare)
ET = Evapotranspiration (in mm)
