Question

Duty of water of canal system does not depends on

• A. Area of land irrigated
• B. Method of cultivation
• C. Type of the crop
• D. Base period of the crop

Hint:

Duty of water is a measure of efficiency, expressed as Hectares/cumec.
Think of it like the "mileage" of water. Better mileage (higher duty) depends on the car (crop type), driving conditions (climate, soil), and driver skill (cultivation method).
The total distance traveled (area irrigated) is a result, not a cause, of the mileage.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
Which factor does NOT affect duty of water?

Step 2: Key Concept (Alternate):
Duty = Area/Discharge. Factors: crop type, base period, cultivation method, soil, climate. Area is output, not input.

Step 3: Detailed Explanation:
Duty tells how much area 1 cumec can irrigate. It depends on water need (crop, climate) and efficiency (method, soil). Total area is calculated using duty; duty doesn't depend on area. Just like speed doesn't depend on total distance traveled.

Step 4: Final Answer:
Area of land irrigated does not determine duty; duty determines area.
