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 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

Drought is the major problem in India and occurrence at the time of critical growth stages, reduce crop yield significantly. The National Rice Research Institute, Cuttak, Odisha has developed so many drought tolerance rice varieties to reduce the economic loss due to drought. Krishi Vigyan Kendra, Malkangiri introduced NRRI released two rice varieties i.e. Sahbhagi Dhan and Satyabhama at framers' field to evaluate the performance of these drought tolerant varieties in South Eastern Ghat Zone of Odisha. The highest plant height was observed with the rice variety Satyabhama (104.1 cm). But, overall performance of Sahbhagi Dhan was better as compare to Satyabhama and local check verity (Khandagiri). Sahbhagi Dhan gave highest yield of 36.5 q/ha, which was statistically differed from others. Correlations study for Sahbhagi Dhan was assessed and observed the positive correlation for grain yield with all studied characters except plant height. For economic point of view, Sahbhagi Dhan recorded highest net return of Rs.19, 925/- per ha along with B:C ratio of 1.6 as compared to the rest two varieties.

Stress like drought is an important production constraint that drastically reduces rice yield. The present study was conducted during kharif season of 2019 through the front line demonstrations in Malkangiri district of South Eastern Ghat Zone of Odisha to evaluate the performance of drought tolerant rice variety Swarna Shreya with recommended package (demonstrated technology) of practices. Rice variety Sahabhagi dhan was considered as local check (farmers practice). Performance of Swarna Shreya was better in terms of plant height (110.4 cm), number of tillers hill-1 (17.8), panicle length (23.5 cm), number of grains panicle-1 (162), test weight (23.4 g) with yield of 42.4 q ha-1. In terms of yield, it was 15.2% more with Swarna Shreya as compared to local check Sahabhagi dhan. Highest economic return with more B: C ratio (1.8) was also recorded with Swarna shreya. So, drought tolerant rice variety Sahabhagi dhan can be replaced with Swarna Shreya for more yield and higher economic return in rainfed upland ecosystem of South Eastern Ghat Zone of Odisha.
