This study was conducted in Dangur District at Pawe Agricultural Research Site during 2013 cropping
season. The aim of the study was to identify the effect of seed age and varieties on physical, physiological and
health quality of soybean. The experiment was done on two varieties (Belessa-95 and TGX) having two different
ages (year one and year two). The study employed SAS computer software and the treatments significant differences
were subjected to LSD (least significant difference) test for mean separation at (p<0.01) and (<0.05) significant
levels. Analysis of variances showed that significant (p≤0.01) differences were recorded among physical purity
components and germination due to the main effect of seed age. The highest mean of analytical purity (61.88 %)
was obtained in year one and the lowest mean (42.63) were recorded on year two. The highest mean of germination
was (72.63%) on year one and lowest mean of germination (38.62) were recorded on year two. The highest mean
density (5.94%) of Pseudomonas syringe was observed on the combination of TGX by year two and the lowest
mean was recorded on same varieties (0.06%) for Pythium and Botrytis. Therefore among the two different soybean
varieties (Belessa-95 and TGX) having the two different storage years (year one and two) those soybean varieties
with one storage year were indicated maximum seed quality performance.
