Studies were carried out to find out the Influence of different packaging materials and storage conditions on the seed quality parameters of groundnut. Groundnut seeds were stored in different packaging materials viz., gunny bags, high density polythene bags and vacuum packed bags and stored at room temperature (25 ± 2º C) and cold storage (4 ± 1º C) for a period of 18 months. The treatments having six combinations and consisting of different containers viz., gunny bags, high density polythene bags and vacuum packed bags were replicated four times in both cold and ambient storage conditions in completely randomised block design. The results of the study revealed that the seed quality parameters viz., germination per cent, root length, shoot length, seedling vigour index and seedling dry weight decreased with an advancement of storage period but the electrical conductivity values were increased with advancement in storage period. While the more fluctuation was seen in moisture content values throughout storage period but it was constant for vacuum packaging. Among the containers, the seeds stored in vacuum packed bags maintained the quality with least deterioration compared to seeds stored in gunny bags and high density polythene bags. It was also observed that the seeds stored in vacuum packed bags maintained the seed quality with least deterioration with respect to all the seed quality parameters compared to seeds stored in gunny bags and high density polythene bags.
