In eastern India especially Odisha, canal irrigation is dominant in which water is flooded from field to field where farmers have less control over the flow of water. The water flows continuously through the fields, and the water distribution is quite irregular, with heavy percolation loss of applied irrigation water. The inclusion of field channels in existing flood irrigation system provides better control over water resulting in 15% saving of irrigation water (Fig. 3.8). The irrigation efficiency of this system is around 50%. However, channel to field method can achieve a considerable increase in water use efficiency (17% higher) and grain yield (7-8% higher) of rice comparable to farmer's traditional practice of field to field irrigation.
