Abstract: The present study was carried out to investigate the effect of different physical and chemical methods of seed treatment on germination and growth of guava seedling (Psidium guajava L.). Among the different physical and chemical methods of seed treatment, seeds treated with GA₃ at 1000 ppm for 24 hours resulted in maximum germination percentage (88.56%), highest seedling length (65.73 cm), highest girth of the seedling (2.42 mm) and highest survivability (70.58%). Sowing of seed without seed treatment showed poor performance in terms of germination and seedling growth.
