i) Traditional Method
In our country traditional systems of
- pulley system (moat)
- chain pump and
- lever system (rahat)
have been used for centuries to lift
water from water reservoirs and supply
it to the field for irrigation.
methods are cheaper but not much
ii) Modern Methods
a. Furrow irrigation: In this method
water is allowed to enter the field
through channels of furrows made
between two rows of crop. e.g., sugar
cane, banana, paddy, etc.
b. Basin irrigation: In this method the
field is just filled with water.
e.g. Paddy field.
c. Sprinkler irrigation: This irrigation
is used where the soil cannot retain
water for a long time. Here the water is
sprinkled by sprinklers. e.g. Lawn
d. Drip irrigation: In this irrigation the
water falls drop by drop directly at
the position of the roots, so it is called
drip irrigation. It is the best method to
save water. It helps to irrigate grapes,
banana, brinjal, etc.
