Question

Which is the most water-efficient irrigation system?
1. Surface
2. Flood
3. Drip
4. Sprinkler

Answer 1

Correct Answer - Option 3 : Drip

Explanation:

• Drip Irrigation: Drip irrigation is the most efficient water and nutrient delivery system for growing crops. It delivers water and nutrients directly to the plant’s roots zone, in the right amounts, at the right time, so each plant gets exactly what it needs, when it needs it, to grow optimally. 
• Working: Water and nutrients are delivered across the field in pipes called ‘dripper lines’ featuring smaller units known as ‘drippers’. Each dripper emits drops containing water and fertilizers, resulting in the uniform application of water and nutrients directly to each plant's root zone, across an entire field. 
• Features:
  • Higher consistent quality yields
  • Huge water savings: no evaporation, no runoff, no waste
  • 100% land utilization - drip irrigates uniformly in any topography and soil type
  • Energy savings: drip irrigation works on low pressure
  • Efficient use of fertilizer and crop protection, with no leaching
  • Less dependency on weather, greater stability, and lower risks
