|Class 9 Biology Improvement Food Resources||Irrigation|
The process of watering plants to ensure that crops get enough quantity of water atproper phase during their growing season to increase the expected yields of any crop is called irrigation.
Wells: In adug well, water is collected from waterbearing strata. Tube wells can tapwater from the deeper strata. Water is then lifted up using pumps fromthese well to water the plants.
Canals: They receive water from oneor more reservoirs or from rivers. Themain canal is divided into branchcanals having further distributaries toirrigate fields.
River Lift Systems: This system is more useful in areas having insufficient or irregular canal flow as a result of inadequate reservoir release.
Tanks: These are small storagereservoirs intercepting and storingthe run-off of smaller catchment
