The laboratory experiment was conducted to study the effect of seed treatment on storage potential of onion cv. CO (On) 5 through forced ageing or accelerated ageing. The onion seeds were given with different treatments such as T1 - Control, T2- Seed coating formulation I @ 10 g/kg, T3 - Seed coating formulation II@ 10 g/kg and forced aged for ten days. The forced ageing significantly influenced the germination of onion seeds and also had negative relationship. The seeds coated with formulation I and II obtained germination above IMSCS (70%) upto 7 and 8 days, respectively, whereas the untreated seeds retained only up to 5 days. The significant influence was observed in seedling length (SL), dry matter production (DMP) and vigour index (VI) due to forced ageing. It was decreased while increasing the period of forced ageing. The maximum SL, DMP and VI was recorded in T3 (11.2 cm, 14.0 mg seedling-10 and 706) followed by T2 (10.4 cm, 13.5 mg seedling-10 and 614) after 10 days of forced ageing. It was recorded minimum in T1 (8.4 cm, 13.1 mg seedling-10 and 420). Hence, seed coating formulation I or II can be used to prolong the self-life of onion seeds.
