A panipipe, a simple technology developed by the International Rice Research Institute, and the AWD enable growers to determine when it is necessary to irrigate, and subsequently reduce their overall level of water use while improving their farming efficiency and sustainability of rice growing. Syngenta has already worked with IRRI in Bangladesh to introduce this simple water saving device and technique to farmers.
A tensiometer-based irrigation scheduling for rice, an innovation by Punjab Agricultural University, continuously monitors soil water content which is effective for scheduling irrigation.
