The lab experiment was laid out with completely randomised block design to study the effect of different seed packing materials with silica gel and vacuum packing on seed longevity of onion variety Arka Kalyan with three replications for twelve months at Seed Testing and Research laboratory, Seed Unit, University of Agricultural Sciences, Raichur. The results showed that, the impervious containers recorded minimum seed deterioration compared to previous container (cloth bag). It was notified that the minimum seed deterioration of quality parameters were found in seeds packed in aluminum-laminated pouches with vacuum packing + silica gel (100 g/kg seed) viz., seed germination ( %), root length ( cm), shoot length ( cm), seedling vigour index (1265), seedling dry weight ( mg), electrical conductivity ( dSm-1), dehydrogenase enzyme activity ( OD value) and α-amylase enzyme activity ( mm) which were on par with seeds packed in polythene bag (700 gauge) with vacuum packing + silica gel (100 g/kg seed), aluminum-laminated pouches with vacuum packing, polythene bag (700 gauge) with vacuum packing, aluminum-laminated pouches silica gel (100 g/kg seed), polythene bag (700 gauge) silica gel (100 g/kg seed), aluminum-laminated pouches and polythene bag (700 gauge) over control ( %, cm, cm, 858, mg, dSm-1 , OD value and mm, respectively) after twelve months of storage period. | Evaluation of the best storage methods for maintaining seed quality of onion
