ABSTRACT

The importance of seed age, varieties and spacing on soybean seed yield and quality has not been established in Ethiopia. This study was conducted in Dangur District at Pawe Agricultural Research Site with the objective of evaluating the effect of seed age and soybean varieties on growth, yield components and yield to assess the effect of seed age and varieties on physical, physiological and health quality of soybean during 2013 cropping season. The experiment was designed with factorial combinations of three intra row spacing (5cm, 10 cm and 15 cm), two seed age (year one and year two) with two varieties Belessa-95 and TGX was laid out in a randomized complete block design with three replications. Analysis of variances showed that significant (p?0.01) differences were recorded for days to flowering, plant height, number of branches, number of pods per plant, cluster per plant, pod per cluster, yield and above ground dry biomass occurred due to the main effect of seed age. Similarly days to flowering and plant height were affected by three way interaction effect. The significantly higher number of pods per plant (104.82), above ground dry biomass (3676.0 k/ha) and grain yield 2303.3kg/ha was recorded on year one. Therefore, it could be concluded that the combination of both soybean varieties in Dangur District area year one attained maximum yield.
