Impact of drip irrigation on water use efficiency and yield in rice (Oryza sativa L.)

Abstract

Rice (Oryza sativa L.) is a staple food crop for more than half of the world's population, predominantly grown in water-intensive paddy fields. However, increasing water scarcity due to climate change and competition for water resources necessitates the adoption of more efficient irrigation techniques. Drip irrigation, known for its high water use efficiency (WUE), is emerging as a viable alternative to traditional flood irrigation methods in rice cultivation. This review examines the impact of drip irrigation on water use efficiency and rice yield. It discusses the benefits, challenges, and potential strategies for optimizing drip irrigation in rice farming.
