Understanding the Potential Effects of the Field Water Management System with Remote and Automatic Control on Irrigation Water Volume and the Labor for Water Management Associated with Rice Cultivation

Abstract

This study conducted research on the water requirement and labor for water management throughout the cropping season for paddy fields where the field water management system introduced water saving and labor required. The system was allowed the maintenance of stable water levels specified by users automatically. The system enabled irrigation according to the necessary water volume and timing. The irrigation water volume used by the system 53% compared to manual control. The labor required for water management decreased by 85%. The system did not affect the crop yields. The introduction of the system led to the water saving and labor reduction without sacrificing the crop yields.
