Purposes of Irrigation

  • Providing insurance against short duration droughts
  • Reducing the hazard of frost (increase the temperature of the plant)
  • Reducing the temperature during hot spells
  • Washing or diluting salts in the soil Softening tillage pans and clods
  • Delaying bud formation by evaporative cooling
  • Promoting the function of some micro organisms

Objectives of irrigation

  • To Supply Water Partially or Totally for Crop Need
  • To Cool both the Soil and the Plant
  • To Leach Excess Salts
  • To improve Groundwater storage
  • To Facilitate continuous cropping
  • To Enhance Fertilizer Application- Fertigation

Benefits of Irrigation

  1. Increase in Crop Yield
  2. Protection from famine
  3. Cultivation of superior crops
  4. Elimination of mixed cropping:
  5. Economic development
  6. Hydro power generation
  7. Domestic and industrial water supply:
