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 Swarna- sub-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 http://www.agriculturejournal.org/volume8number1/evaluation-of-excess-water-tolerant-rice-varieties-swarna-sub-1-and-cr-1009-sub-1-under-head-to-head-project-in-east-and-south-eastern-coastal-plain-zone-of-odisha/ Stress Tolerance Rice; Nursery Management; Post Flood Management; Submergence; Survival
