The intelligent management system of water and fertilizer were set up in Taiwan Agricultural Research Institute, Miaoli District Agricultural Research and Extension Station, and Taichung District Agricultural Research and Extension Station, respectively. These three stations were equipped with intelligent water level monitors, which could coordinate the real-time water level sensors and solenoid valve to adjust the consumption of irrigation water for three different rice varieties. In addition, unmanned aerial vehicle was used to capture aerial images in the demonstration fields. With the combination of vegetation index from the aerial photography and the physiological parameters measured in field, researchers and farmers could make cultivation decisions according to the nutritional status of rice plants.
