Right Answer is:

Duty

SOLUTION

The term duty means the area of land that can be irrigated with the unit volume of irrigation water.

Duty represents the irrigating capacity of a unit. It is the relation between the area of a crop irrigated and the quantity of irrigation water required during the entire period of the growth of that crop.

D = A/Q

Where

A = Area of land irrigated

Q = Rate of water supply

Duty is measured in hectares/cumec (ha/cumec).
