The present study was conducted to determine the effects of soaking in potassium humate (PH) solution (55% humic acid, 30% fulvic acid and 8% potassium hydroxide) and distilled water (DW) for different periods (0, 4, 8 and 16 hours) on germination characteristics of undelinted seeds of cotton cv Ersan-92. Radicle, hypocotyl and seedling length, radicle and hypocotyl elongation rate and vigor index increased by PH solution treatment and increasing soaking periods. The medium x soaking period interactions were significant except for germination percentage. Sixteen hour soaking period gave the highest values of investigated characteristics. It is suggested that pre-sowing PH solution treatment may be useful to provide a good stand establishment.
