In Nagaon, the total area under flood and drought condition was estimated to be 17833 ha out of 151744 ha net cropped area, which is approximately 11.75 % of the cultivable land covering more than 50 villages, thereby causing huge loss in the income of farming community. Since long back, Krishi Vigyan Kendra, Nagaon has been serving as link for dissemination of paddy crop varieties suitable for cultivation under flood and submergence conditions: viz. Ranjit Sub-1, Swarna Sub-1, Bahadur Sub-1 to encompass the loss situation in the farmers field as resilient technology. Therefore, this particular study is an attempt to evaluate the status, impact and factors affecting submergence tolerant rice varieties in flood prone area of the district. Primary data with pretested schedule was used to collect data from 100 farmers from flood affected area using stratified random sampling technique. Here yield and economics are worked out by different submergence time interval and was implied that 60% of sample farmers adopted STRV increasing cropping intensity 207% leading to increase of income of farmers by replacing approximately 45% over the local variety even 2 weeks under submergence condition. Logit regression was also carried out in order to examine factor affecting the adoption of flood tolerant varieties and found that excess to extension functionaries with a significant value of .007 (p<0.05), rice acreage with significant value of 0.006 (p < 0.05), access to farm machineries with significant value of 0.02 (p < 0.05), and access to PMFBY had a positive insignificant relation with adoption of submergence tolerance varieties. It is implied that farm mechanization with good linkage extension functionaries are necessary strategies for adoption of submergence tolerant rice varieties.
