Flow irrigation is practiced when
Water level is lower than field level
Water level is higher than field level and moves by gravity
Water is applied through perforated underground pipes
Water is supplied only by pumps
Inundation (flood) irrigation is also called
Controlled irrigation
Sprinkler irrigation
Uncontrolled irrigation
Subsurface irrigation
Direct irrigation is best described as
Both storage and diversion of water

Free flooding
The method best suited for orchards only is
Furrow irrigation
Ring basin flooding
Border strip method
Sprinkler irrigation
Direct irrigation involves both storage and diversion of water (a)
Storage irrigation is constructed in non-perennial rivers (a)
Assertion (A): In furrow irrigation, plants do not have direct contact with water. Reason (R): Plants receive water mainly due to lateral percolation from furrows.
Both A and R are true and R is the correct explanation
Both A and R are true but R is not the correct explanation
A is true but R is false
A is false but R is true
Perennial irrigation is also called (a) irrigation.
In inundation/flood irrigation, soil is kept (a) with water.
Direct irrigation is also called (a) canal irrigation system.
Example of direct irrigation mentioned is the (a) canal system (1856).
