In recent years, the effects of global climate change have led to a continuous decline in water resources, making it increasingly difficult to meet the growing demand for freshwater. Globally, the highest proportion of irrigation water is used in agricultural activities. In conventional farming, commonly preferred irrigation methods are often associated with unregulated and excessive water use. This has become a major factor in the rapid depletion of water resources. Controlled irrigation systems, widely implemented in modern agricultural practices, help reduce plant water consumption and ensure more efficient use of water. The advancement of computer and electronic systems has increased technological support in agricultural irrigation systems, thereby contributing to improved crop productivity. With the development of computer technologies, determining the water requirements of crops and creating soil water budgets has become significantly more accurate and important. This study investigates the real-world evaluation of a photovoltaic solar energy-supported subsurface irrigation automation system, as well as a non-automated drip irrigation application, by utilizing the solar energy potential of Yozgat province. The solar-powered pressurized irrigation automation system consists of a direct current motor pump connected to photovoltaic (PV) solar panels and a control unit. Subsurface and drip irrigation systems were installed on designated plots. To determine the water requirement of the common bean plant, the CROPWAT program was used, and the solar-powered irrigation automation system was designed accordingly. Experimental trials were conducted on plots cultivated with common beans, and comparisons were made between the automated subsurface irrigation system and the non-automated drip irrigation application. According to the data obtained, the automated irrigation system positively contributed to plant productivity. The solar-powered subsurface irrigation application resulted in a 73.3% increase in yield compared to the nonautomated drip irrigation method. The design and implementation of the solar-powered subsurface irrigation automation system were proven to be feasible under real field conditions.
