Answer
Drip irrigation is the most advanced and efficient method of irrigation. This system consists of perforated pipes that are placed between rows of crops or buried along their root lines and give water directly on to the crops.
It is useful as it reduces evaporation drastically and irrigation water is conserved. It also allows the grower to customise an irrigation programme most beneficial to each crop.
