Abstract: An investigation was undertaken to identify the effect of seed priming on vigour in fresh and aged seeds of onion (var. Arka Kalyan). It was observed that seed priming with GA₃ (50 ppm), KNO₃ (3 %) and PEG (-1.5 Mpa) were shown significant impact on germination and vigour. Aged seeds responded to the priming treatments effectively than fresh seeds. Among various treatments studied, there was an increase of germination in fresh seeds to the extent of 5 % due to treatment with GA₃, whereas in aged seeds it was to the extent of 11 % due to PEG treatment.
