Flash flood or submergence is a common phenomenon in rice growing rainfed lowland areas that seriously affects crop establishment leading to severe yield losses. A few submergence–tolerant rice varieties have been developed by introgression SUB-1 gene into mega rice varieties of South Asia. Performance of this variety can be further enhanced through adoption of appropriate management practices. Farners Participatorty trials were conducted using Swarnasub-1 and CR 1009 sub-1 during kharif, 2017 in three adopted villages at Erasama, Kujanga and Raghunathapur blocks of Jagatsinghpur district. Results of this experiment revealed that at recommended doses of N:P:K @ 80-40-40 Kgha-1, transplanting of 30 days aged seedlings and additional N-dose of 20kg/ha at 7 days after receding of flood water resulted in better post submergence recovery and maximum yield. Maximum number of tillers m-2 was recorded in CR 1009 sub-1 followed by Pooja and Swana Sub-1. Rice variety Swarna Sub–I rerecorded an yield of 55.23 q ha-1 which was 14.5% higher as compared to farmers variety Swrana 48.2 q ha-1. The Swarna Sub-1 and CR 1009 sub-1 survived in the flood and gave higher yield under submergence condition in the coastal flood prone area.
