What are the ways of crop irrigation?

Crop irrigation methods include surface irrigation, where water flows over the soil surface, and drip irrigation, which delivers water directly to the plant roots through a network of tubing. Other methods include sprinkler irrigation, which mimics rainfall by spraying water over crops, and subsurface irrigation, where water is applied below the soil surface. Each method varies in efficiency, cost, and suitability depending on factors like crop type, soil characteristics, and water availability.
