In this type of method, it involves laying a system of head, mains, sub-mains, laterals and drip nozzles, water oozes or trickles out at a small rate into the plant roots area. Hence the name trickle irrigation method.

Because good irrigation has uniform water distribution for both light irrigation and heavy irrigation. It also reduces conveyance and labor losses. It also facilitates mechanized farming. So, these advantages lead to increase yield.

This type of method used in an inundation irrigation system in which water is forced to spread or flooded on a flat land, without much control or prior prepration. This leads to wasteful use of water.

Irrigation by this type of method is done, by dividing the entire land to be irrigation into a number stripes called laterals. These laterals may be perpendicular to the sides of the field or perpendicular to the contour lines.so, as this method uses contour lines of field it is suitable for both flat lands and steep lands.

This type of method uses borders to divide the land into strips of with 10 to 20 meters, 100 to 400 meters in length each. Ridges are provided between borders so as to prevent overtopping during irrigation. Supply ditches run perpendicular to borders either on one side of the field to provide water for irrigation
