Present study was carried out on two varieties of oat i.e. OS 6 and HFO 611 having two seed lots (Fresh and one year old) in order to standardize the hydro-priming technique for enhancing planting value of oat seeds. The results revealed that maximum germination (100%) was recorded in fresh seed lot of OS 6 after 14 hours of direct soaking in 1½ times volume of water while it was recorded 96% in old lot after same soaking duration and volume of water. At half volume of water, maximum germination (99%) was recorded after 26 hours soaking duration while at equal volume of water, germination was found maximum (99%) at 24 hours soaking duration as compared to control (95%). Same trend was observed in other seed quality parameters also and maximum vigour index-I (3300), Vigour index-II (1162) and field emergence (65%) was observed at 14 hours soaking duration in 1½ times volume of water. One year old seed lot recorded more improvement in seed quality as compared to fresh seed lot. More enhancement in seed quality parameters was recorded in OS 6 over HFO 611. It is concluded from the study that hydro-priming for14 hours by direct soaking in one and half volume of water under ambient condition (20+2oC) is optimum for enhancing the seed quality in oat. If volume of water is reduced to half or equal quantity of water then soaking duration should be increased upto 26 and 24 hours respectively.
