This study\\r\\ninvestigates the impact of seed aging on physiological traits and seed quality\\r\\nin rapeseed and mustard (Brassica spp.), focusing on plant height, siliquae per\\r\\nplant, and seed yield. Fresh and aged seeds from six Brassica varieties-PM-28,\\r\\nM-27, TS-36, TS-38, Kakching Yella, and Potsangbam Yella were cultivated under\\r\\nuniform field conditions at Pandit Deen Dayal Upadhyay Institute of\\r\\nAgricultural Sciences, Manipur, using a factorial randomized block design.\\r\\nResults revealed significant reductions in plant height, siliquae production,\\r\\nand seed yield across all aged seed varieties. For instance, fresh seeds of PM-28\\r\\nattained a maximum plant height of 95.00 cm, while aged M-27 seeds recorded the\\r\\nshortest height (63.50 cm). Similarly, seed yield dropped sharply from 1258.75\\r\\nkg/ha in fresh PM-28 seeds to 451.25 kg/ha in aged Potsangbam Yella seeds.\\r\\nThese findings underscore the necessity of optimal seed storage to maintain\\r\\nphysiological vigor and ensure agricultural productivity.
