The fresh seeds of cumin variety viz., GC 4 obtained from Agricultural Research Station, Halvad, College of Agriculture, Junagadh Agricultural University, Junagadh were treated with Carbendazim, Mencozeb, Neem Cake, Thiram, Silica gel, Calcium Chloride, Quinalphos, Tebuconazole, Silica gel with Calcium Chloride and Tebuconazole and untreated seed (control) were stored in moisture vapour proof high density laminated polyvinyl bag, polyvinyl bag (700 gauge), aluminum foil laminated bag, plastic linted jute bag, polyvinyl bag packing with vaccum and cloth bag (control) in laboratory under ambient conditions. At 150 and 250 days of storage periods, the seed moisture per cent, germination percentage, first count of seed germination, speed of germination, shoot length of seedling (cm), root length of seedling (cm), seedling length (cm), seedlings fresh weight (g), seedlings dry weight (g), strong seedlings, weak seedlings, seed vigour index (length based), seed vigour index (mass based), test weight (g) and drugstore beetles and cigarette beetle infestation (%) were determined. The results of present investigation revealed that among the seed treatments, silica gel helped to maintain the higher germination per cent, strong seedling, lower weak seedling, seed vigour index (length) and test weight. Seed treatment with thiram helped to maintain the highest speed of germination, shoot length, root length, seedling fresh weight, dry weight, seed vigour index (mass) and drugstore beetles and cigarette beetle infestation. In case of seed containers, Polyvinyl bag packing with vaccum seed container was found superior than rest of other containers by recording lowest moisture content, higher germination percentage, first count of seed germination, root length of seedling, seedling length, seedling fresh weight, seedling dry weight, strong seedlings, seed vigour index (length), seed vigour index (mass) and lowest test weight, while seeds stored in aluminum foil laminated bag recorded significantly highest speed of germination, lowest weak seedling and seeds stored in moisture vapour proof high density laminated polyvinyl bag recorded the highest shoot length. In case of storage study, it was observed that most of the seed quality parameters i.e. test weight, seed moisture per cent, weak seedlings and drugstore beetles and cigarette beetle infestation per cent increased with further increase in the storage periods, while germination percentage, first count, speed of germination, root length and shoot length of seedlings, seedling length, strong seedlings, seedlings fresh weight, seedlings dry weight, seed vigour index (mass based) and seed vigour index (length based) decreased with increase in storage periods. Seeds stored in polyvinyl bag packing with vaccum and treated with silica gel maintained lowest seed moisture per cent, highest germination per cent, first count, strong seedling, seed vigour index (length) and test weight. While seeds stored in polyvinyl bag packing with vaccum treated with thiram have the highest root length (cm), seedling fresh weight, highest seedling dry weight, highest seed vigour index (mass) and lowest drugstore beetles and cigarette beetle infestation. Seeds stored in aluminum foil laminated bag treated with silica gel maintained the lowest weak seedling. Seeds stored in aluminum foil laminated bag treated with thiram maintained the highest speed of germination. While seeds stored in moisture vapour proof high density laminated polyvinyl bag treated with thiram maintained the highest shoot length (cm). Thus, from the results of the present study, it seems quite logical to note that the seeds of GC 4 treated with thiram, silica gel and stored in aluminum foil laminated bag and polyvinyl bag packing with vaccum for packaging of cumin seeds appeared suitable for maintaining seed quality.enSEED SCIENCEThesis
