Field water use efficiency (FWUE) is calculated by
A. $$\frac{{\text{Y}}}{{{\text{WR}}}}$$
B. $$\frac{{\text{Y}}}{{{\text{ET}}}}$$
C. $$\frac{{\text{Y}}}{{{\text{IR}}}}$$
D. None of the above
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:$${\text{WUE}} = \frac{{\text{Y}}}{{{\text{ET}}}}$$
Y = Dry matter production (kg/ha)
ET = Evapotranspiration (in mm)
