This study investigated the effects of varying salinity levels on the growth performance of eggplant (Solanum melongena L.). Four treatments were applied: control (0.03 ppt), low salinity (3 ppt), moderate salinity (6 ppt), and high salinity (9 ppt). The experiment was conducted over five months under rain-shelter conditions at Universiti Pendidikan Sultan Idris, employing a Randomized Complete Block Design (RCBD) with three replications and 60 plants in total. Growth parameters evaluated included plant height, canopy area, number of leaves, leaf surface area, and root length. Data were analyzed using ANOVA and LSD tests at a significance level of P ≤ 0.05. The results revealed that salinity significantly (P ≤ 0.01) affected all growth parameters. Plants exposed to higher salinity levels exhibited stunted growth and reduced biomass accumulation. The findings indicate that S. melongena can tolerate salinity up to 3 ppt, although mild growth inhibition may still occur. These results provide useful insights into the salinity tolerance thresholds of eggplant for future cultivation in saline-prone environments.
