A field experiment was conducted at CCS Haryana Agricultural University, Hisar to study the effect of natural ageing and seed priming on field parameters of Indian mustard. Three variety of Indian mustard viz., RH-30, RH-9304 and RH-0406 with three seed lot were evaluated for vigour and viability parameters under field conditions. The results revealed that seed lot L1 was found maximum seedling emergence index and seedling establishment followed by seed lot L2 and minimum seedling emergence and seedling establishment was found in the seed lot L3 during the year 2015-16 and 2016-17. Among the variety, RH-30 was found maximum seedling emergence and seedling establishment followed by variety RH-9304 and minimum seedling emergence index and seedling establishment was recorded in the variety RH-0406 during both the year of study. In case of mean emergence time maximum mean emergence time was found in the seed lot L3 and minimum mean emergence time was found in the seed lot L1. Variety RH-0406 was found highest mean emergence time followed by RH-9304 and lowest mean emergence time was found in the variety RH-30. All seed priming treatment enhanced the seed quality significantly in case of all physiological parameters in naturally aged seed lots of different varieties of Indian mustard. Among different priming treatments, hydration with GA3 (@ 50 ppm) was reported superior for enhancing the seedling emergence and seedling establishment of all the seed lots of different varieties of Indian mustard. Maximum enhancement was found in the variety RH-30 followed by RH-9304 and minimum improvement was recorded in the variety RH-0406 during both the year. It can be concluded that seed treatment with GA3 could be used for enhancing the field emergence of Indian mustard.
