What is Irrigation System?
An irrigation system is a method or infrastructure used to provide water to crops in agricultural fields. It helps in supplementing natural rainfall by delivering water directly to the plant’s root zones. The system typically involves the use of pipes, channels, pumps, sprinklers or drip emitters to distribute water efficiently and effectively across the cultivated area. The main purpose of an irrigation system is to ensure that crops receive adequate moisture for their growth, even in areas with limited rainfall or during dry seasons. It plays a vital role in maintaining crop health, optimizing yield, and supporting sustainable agricultural practices.

Types of Irrigation System
Various types of irrigation systems are employed worldwide to meet the diverse needs of different regions and crops. Here is a tabulated description of them.
|Irrigation System||Characteristics||Prominent Areas of Usage|
|Surface Irrigation||Water is distributed over the soil surface and infiltrates the soil through gravity flow.||
|Sprinkler Irrigation||Water is sprayed through sprinklers, creating a fine mist that falls onto the crops.||
|Drip Irrigation||Water is applied directly to the plant root zone in small, controlled amounts through drip emitters.||
|Center Pivot Irrigation||Water is distributed from a central pivot point, with sprinklers rotating in a circular pattern.||
|Subsurface Irrigation||Water is delivered directly to the root zone through buried pipes or tubes.||
