two modern methods of irrigation -

drip irrigation

sprinkle irrigation

Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 litres/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers.

Sprinkler irrigation is a method of spreading water similar to natural rainfall. Water is distributed through a system of pipelines which is sprayed through air by rotating sprinklers so that it breaks up into smaller droplets of water as they fall to the ground.

Hope it helps
