In modified atmospheric storage assays on seed quality of Groundnut seed kernels revealed that the seed kernels exposed to gaseous combination of 60 % N2 + 40 % CO2+ 0 % O2 and stored in 700 gauge polyethylene bag maintained better quality in terms of germination and vigour up to ten months of storage followed by vacuum storage, whereas in control, prescribed germination of 70% was noticed up to fou r months only. Among the packaging materials, groundnut seed kernels stored in 700 gauge polyethylene bag showed better seed quality parameters viz., germination (60 %), root length (5.23 cm), shoot length (4.29cm), seedling vigour index (522), dehydrogena se enzyme activity (0.103 OD value) and lower electrical conductivity of seed leachate (1.127 dSm - 1) after tenth months of storageas compared to 400gauge polyethylene bag. The aim of the study was to determine the level of gaseous combination and storage c ontainers on effective storage of groundnut seeds.
