Field experiments were conducted during the wet and dry seasons of 2004–05 and 2005–06 to study the influence of fish cum poultry on the productivity and sustainability of rice-rice system. The treatments consisted of five rice-fish-poultry models compared with conventional rice-rice system. The mean data revealed that rice-fish-poultry integrated farming system recorded higher growth, yield and yield attributes during both the years over the conventional system of rice-rice. Among different models, rice + fish (pit dug at the centre of the rice field) - Poultry (reared separately) recorded the highest system productivity (9118 kg/ha/year) and Sustainable yield index (89.2%) followed by rice + fish (pit dug at one side of the rice field and connected by trenches) - Poultry reared in the cage above the fish pit (8697 kg/ha/year and 84.2%, respectively) and rice + fish (pit dug at one side of the rice field) - Poultry reared in the cage above the fish pit (8533 kg/ha/year and 81%, respectively).
