Background and Objective: The problem of drought is a scourge for oil palm farmers in Indonesia, the development of oil palm plantations is directed to areas that have dry land potential with a dry climate, longer dry months and lower rainfall. The purpose of this study was to determine the physiological character of oil palm seedlings due to water stress and Bokashi treatment. Materials and Methods: The experiment was conducted in June to September, 2021. The experiment used a non-factorial completed randomized design with 9 treatments and 2 replications. The observed variables were leaf chlorophyll, total protein, total sugar and p5CS gene expression level by the qPCR method. Results: The results showed that the less water, the smaller the leaf chlorophyll, while the total sugar and total protein tended to be higher and the p5CS gene expression level by qPCR method activity under water stress conditions of 14.58 was higher than under conditions of sufficient water. Conclusion: The physiological character of oil palm seedlings differs in the treatment with sufficient water and lack of water.
