Question

The efficiency of irrigation system is maximum in:

• A. Surface irrigation
• B. Sprinkler irrigation
• C. Drip irrigation
• D. Furrow irrigation

Hint:

Drip irrigation can achieve irrigation efficiencies of more than 90%.

Answer 1

The Correct Option is C

The question asks about the efficiency of different irrigation systems. To determine which system offers the maximum efficiency, let's explore the options:

1. Surface Irrigation: This method involves spreading water across the land surface. While it is commonly used due to its simplicity and low costs, its efficiency is relatively low. Water loss is higher due to evaporation and runoff.
2. Sprinkler Irrigation: This system mimics rainfall by distributing water through overhead pipes. It is more efficient than surface irrigation but still has significant losses due to wind drift and evaporation.
3. Drip Irrigation: In this method, water is delivered directly to the root zone of plants through a network of valves, pipes, tubing, and emitters. With minimal evaporation and runoff losses, drip irrigation is the most efficient method.
4. Furrow Irrigation: Water is directed down furrows or channels across the field. Similar to surface irrigation, furrow irrigation has higher water loss through evaporation and infiltration beyond the root zone.

Given these explanations, the most efficient system is Drip Irrigation. It delivers water only where it is needed and minimizes losses, making it especially suitable for water-scarce areas.

Therefore, the correct answer is: Drip irrigation.
