Paddy in the southwest coastal region of Bangladesh continues to support food security and GDP growth. But in the recent past, it has decreased due to salinity. This study aims to detect the most resilient paddy variety to the salinity intrusion condition and identify the most important fertilizer that contributes to more paddy cultivation in this situation. Translog production function is used to assess the impact of salinity on Aus, Aman, and Boro paddy in the salinity affected southwest coastal region and salinity free northwest coastal region for comparison. This estimate is based on collected data from the sample farmers of southwest and northwest Bangladesh through the purposive sampling and questionnaire survey. dSm-1 of paddy farms of sample farmers are measured by the salinometer. The findings suggest that proper utilization of essential inputs can play an important role to produce paddy properly under the salinity prevailing condition.
