CORH 3 hybrid rice seeds were coated with different polymers, namely Genius coat 171, Genius coat 172, Arcus, Myconate and Quick roots and evaluated for various physiological quality parameters at water holding capacities of 30, 40, 50, 60, 70 and 80% in sand medium along with untreated control. The seeds coated with Quick roots polymer performed well even under suboptimal moisture condition like 30% water holding capacity, recorded 18, 15, 11, 13 and 13 per cent higher speed of germination, rate of germination, root length, shoot length, dry matter production and vigour index, respectively over untreated control. The result indicated that the rice seeds coated with Quick roots can tolerate both high as well as low moisture content and produce better germination and seedling establishment
