BOARD CLASSIFICATION OF METHODS OF IRRIGATION AND THEIR EFFICIENCIES

Methods of irrigation cab are broadly classified under three headings as follows:

  1. Surface irrigation methods.
  2. Spray or sprinkler irrigation.
  3. Sub-soil methods of irrigation.
  • In surface irrigation methods, irrigation water is sprea sheet on the surface of the fields to be irrigate.
  • The application efficiency of surface methods is low as lot of irrigation water lost by evaporation and deep percolation.
  • If fields are prepare in suitable lengths and slope, and surface roughness and soil
  • Infilteration ratio are some how scientifically design and controlled.
  • the application efficiency of these methods can be increased as much as 50 to 60 percent.

METHODS OF IRRIGATION

  • In sub-soil method of irrigation water is not applie at the surface of the fields but at the root zone of the crops.
  • It is possible to achieve even higher than 80% irrigation efficiency by this method of irrigation.

    We gain a firm knowledge and understanding of the Mechanical Design by this blog. I look forward to more updates and will be retuning. Thank you for sharing.
