Explain, how efficiency of irrigation can be increased.
✓

Answer

The efficiency of irrigation can be increased by:
  1. Drip and sprinkler system: It increases the efficiency of irrigation as it sprays water through pipes and a sprinkler.
  2. River lift system: It is useful in those areas where canal flow is insufficient or irregular due to inadequate water release. The water is directly drawn from the rivers for supplement irrigation.
