Question

A wheat crop grown on two hectare area produced 10 ton grain and required 5 irrigations of 6 cm each, find out its field water use efficiency:

• A. 33 kg/ha-mm
• B. 16.67 kg/ha-mm
• C. 3.33 kg/ha-mm
• D. 1.67 kg/ha-mm

Hint:

WUE = Yield (Area \(\times\) Water applied).
Convert cm to mm (1 cm = 10 mm).
Higher WUE means better water use.

Answer 1

The Correct Option is B
