Canal irrigation method is done by directly connecting canal with fields. in canal irrigation its not easy to control flow of water. much of water is wasted .
in drip irrigation method pipe system is applied in fields and pipes have holes. these holes are directed perpendicularly to plants root. and in this system irrigation is done by dropping single-single drop. this doesn't cause water wastage.
