Abstract: Seed size is a component of seed quality which has impact on the performance of crop and variations exist in seed size among variations. Seed size is a key factor in crop improvement. However, scarce information is available on relationship between seed size, variety and seedling emergence characteristics of soybean. Therefore, the study was initiated to determine the effects of variety and seed size on seedling emergence involving four varieties of soybean viz: TGX 1955-4F, TGX 1945-1F, TGX 1448-2E, and TGX 1951-4F. Seeds of each variety were graded into large, medium, and small. 100-seed weight was taken and the same seed lot was grown on the field and evaluated for seedling emergence characteristics. The experiment was a 4 x 3 factorial laid out in a Randomized Complete Block Design (RCBD ) with three replications. Maintenance practices were kept at unform level to chech any form of bias. Data showing emergence characteristics described in the above experiment set-up were collected. The Data were then subjected to Analysis of Variance (ANOVA ) at 5 % level of probability (P < 0.05). Variety exerted significant effect on all the emergence parameters evaluated, but the effect of seed size was only significant on Emergence Rate Index. The results showed that increase in seed size resulted in decrease in emergence percentage. The degree of emergence of seeds may not necessarily be based on the superiority of size of seeds planted. The variety TGX 1945- 1F consistently displayed superiority in all the seedling emergence parameters evaluated ; it is, therefore, recommended for fast and uniform seedling emergence.
