Rising sea levels as one of the major climate change lead to salinity stress of rice farming on coastline area. The study to enable farmers to select the saline tolerant rice varieties through climate field schools. Weekly meetings took place between farmers and university researchers. The university provided training to help farmers to identify their soil health. The experiment as field farmer school was carried out using randomized block design consisted five treatments and provided with replications. Farmers and researchers jointly tested performance indicators of salt-tolerant (Inpari 34, Inpari 41 and Inpara Pelalawan) and flood-tolerant varieties (Inpara 02 and Mendawak). The level of salinity raised from 1.49 to 7.36 dS m⁻¹ (high) during the season. The response to salinity stress showed significant differences of agronomic performance indicators, such as panicle length, number of grain per panicle, weight per plant, weight per plot, and yield per hectare. Contrary to all expectations, the flood-tolerant variety performed better, outperforming the salt-tolerant varieties in many agronomic traits, despite the high level of salinity. Based on a participatory evaluation, farmers decided for Mendawak as best performing variety under salinity stress. The results serve as entry point for upscaling climate-resilient rice farming in this region.
