Geothermal water contains toxic quantities of sulfur, potassium, sodium, boron, and other toxic elements. These toxic elements can substantially restrict germination and seedling growth in rice plant. Germination percentage, average days required for germination and germination velocity were drastically affected by geothermal water. Binato cultivar has higher germination rate compared to IR58 and Unbong 7. Plant height, root length, leaf number and total dry weight decreased with increased geothermal water concentration. Binato and IR58 showed higher total dry weight than Unbong 7 at 25 percent geothermal water at 15 days after treatment (DAT). Binato and IR58 were relatively more tolerant than Unbong 7 in terms of percentage of leaf damage at 25, 50 and 75％ concentration of geothermal water at 10 DAT. The development of large and small vascular bundles decreased with increasing concentration of geothermal water from control to 50％ in three rice cultivars.
