This study was carried out to investigate the agronomic characteristics of late-planted small seed soybean cultivars and to investigate, the effect of number of pods and seeds on main stem and branch against seed yield in Korea. Seed, were sown at 17 June 2003 and 16 June 2004 with on a 60 cm row width and l0 cm plant space. The flowering dates in small seed soybean cultivars were on July 26 to August 7 and the maturing dates were on September 23 to October 9. The days of from planting to flowering date and to maturing date were ranged as 39 -52 and 98-114, respectively. There was a highly significant differences (r=0.686, p0.01) between total dry matter (TDM) and LAI at R5 stage. The number of pods on 2nd branch showed the highest value by 7.6, and followed by that of 3rd, 1st and over 4th branch in this order. The seed yield varied from 168 to 289 g m(-2) and the average of all soybean cultivars was 225 g m(-2). The relation between the seed yield and the days of flowering to maturing date was high significant difference (r
