A farmer needs to study his crops and its root system properly to improve water management. He should choose his system in such a way that water should just saturate the root zone and does not allow water to percolate below the root zone.
The type of irrigation system used by a farmer varies from location to location, crop to crop, year to year and farmer to farmer. It is very important to select an efficient irrigation system in order to maximize efficiency and minimize labour and capital requirement.
Common irrigation systems are:
∙ Drip irrigation
∙ Sprinkler irrigation
∙ Furrow irrigation
