Effect of storage period on seed vigour and germination of soybean and niger, two oil seeds from Central India, were studied. The seeds were stored for a period of 0-7 years in polythene bags under ambient conditions. the study group were control (0 year), short term storage periods (1-3 years) and mid term storage period (4-6 year). Twenty seeds in three replicates were used from each lot for the study. The soybean seeds showed loss of moisture after storage period of two years or more, while niger seeds did not show significant loss of moisture content upto seven years. Soybean seeds showed significant increase in electrical conductivity ( 172.22 ± 4.1 µS cm-1 g-1 for 0 year to 470.34 ± 4.8 µS cm-1 g-1 for 6 years) showing seed deterioration as compared to niger seeds (1.56 ± 0.07 µS cm-1 g-1 for 0 day to 6.44 ± 1.1 µS cm-1 g-1 for 6 years). The soybean seeds stored for mid term storage showed 0-15% germination while for short term stored seeds, the germination percentage was 40-70%. The niger seeds showed 40-60% germination for mid term stored seeds and upto 100% germination for short term stored seeds. The tetrazolium test showed higher numbers of viable seeds in niger as compared to soybean. The study indicates that niger seeds have better storability than soybean seeds under ambient conditions.
