Question

The technical term used to relate the volume of water and the area of crop it matures is

• A. Duty
• B. Delta
• C. Drip
• D. Transpiration ratio

Hint:

Important irrigation terms: \[ \boxed{ \begin{aligned} \text{Duty} &\rightarrow \text{Area irrigated per unit discharge} \Delta &\rightarrow \text{Total depth of water required} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Recall the definition of duty of water. Duty is the area of land that can be irrigated by a unit discharge of water flowing continuously during the crop's base period.

Step 2: Identify the correct term. Thus, the quantity relating the volume (or discharge) of irrigation water to the area of crop matured is called \[ \boxed{\text{Duty}.} \] Hence, \[ \boxed{(A)} \] is the correct answer.
