Question

The ratio of water stored in the root zone during irrigation to the water needed in the root zone prior to irrigation is called:

• A. Efficiency of water use
• B. Efficiency of water storage
• C. Efficiency of water application
• D. Efficiency of water conveyance

Hint:

Maximizing water storage efficiency helps conserve water and ensures better utilization of irrigation resources

Answer 1

The Correct Option is B

The efficiency of water storage is defined as:
\(Efficiency\ of\ water\ storage =\frac{ Water\ stored\ in\ the\ root\ zone}{ Water\  required\  in\  the\ root\  zone\  before\ irrigation} × 100.\)
It reflects the effectiveness of irrigation in replenishing the soil moisture deficit.
