Field water use efficiency (FWUE) is calculated by
Answer & Solution
Correct Answer:
Option
B
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:
$${\text{WUE}} = \frac{{\text{Y}}}{{{\text{ET}}}}$$
Y = Dry matter production (kg/ha)
ET = Evapotranspiration (in mm)
$${\text{WUE}} = \frac{{\text{Y}}}{{{\text{ET}}}}$$
Y = Dry matter production (kg/ha)
ET = Evapotranspiration (in mm)
