Field Evaluation of Smart Irrigation Systems Designed for Precision Agriculture to Optimize Water Use Efficiency and Crop Yield

Abstract

The Water scarcity and inefficient irrigation practices pose significant challenges to sustainable agricultural production, particularly in developing economies where agriculture remains heavily dependent on groundwater resources. Precision agriculture, supported by smart irrigation systems, offers a technologically driven solution to optimize water usage while maintaining or enhancing crop yield. This
study presents a comprehensive field-based evaluation of a smart irrigation system integrating soil moisture sensors, weather data acquisition, wireless communication, and automated control mechanisms. The system was deployed across multiple agricultural plots cultivating staple crops under varying soil and climatic conditions. Performance was assessed in terms of water use efficiency, irrigation scheduling accuracy, crop
growth indicators, and yield outcomes over an entire cropping season. Comparative analysis with
conventional irrigation practices demonstrated substantial reductions in water consumption without compromising crop productivity. The results highlight improved uniformity in soil moisture distribution and reduced water stress during critical growth stages. The study also examines system reliability, farmer
adaptability, and economic feasibility under real-world conditions. The findings confirm that smart irrigation systems can significantly enhance agricultural sustainability by conserving water resources, improving yield stability, and supporting data-driven decision-making in precision farming.
