Irrigation techniques research focuses on developing efficient and sustainable methods for watering crops in agriculture. This includes studying the optimal timing, amount, and method of delivering water to plants to maximize crop yield while minimizing water waste and environmental impact. Some common irrigation techniques studied include drip irrigation, sprinkler irrigation, furrow irrigation, and flood irrigation. Researchers in this area often explore ways to improve water distribution, reduce evaporation, and enhance water use efficiency in order to address the challenges of water scarcity and increasing demand for agricultural production.
