Q: Method of applying water directly to the root zone of the plant is called ..........
  • A. check flooding
  • B. drip method
  • C. furrow method
  • D. sprinkle irrigation
Correct Answer: Option B - In drip method water is directly apply to the root zone of the plants by a network of plastic pipes (PVC Pipes) and drip nozzles called emitters or drippers. Evaporation losses are very less in this method. Highest water application efficiency (as high as 90%). It is not suitable for closely planted crops such as wheat, rice etc. • Sprinkler irrigation method– In this method, water is applied in the form of spray by pipes and nozzle system. In this method no land preparation is required and erosion of soil is eliminated.
