To elucidate the effect of planting patterns on yield performance of soybean, we cultivated early cv. 'Enrei' with 80 and 30 cm row-spacing, and 11.1 and 22.2 plants /spuare m in 2001 and 2002. The number of nodes on main stem, racemes with compound leaves and total number of nodes, were larger in dense planting than in normal planting in both years. The number of branches, nodes on branches, racemes with compound leaves, and total number of nodes per square m were larger in narrow-row planting than in wide-row planting. The length of main stem was longer in dense planting than in normal, and in wide-row planting than in narrow-row planting. The weight, diameter and cross section area of stem were longer (greater) in normal than in dense planting and in narrow-row than in wide-row planting. Seed yield was higher in 2001 than in 2002, in dense planting than in normal planting, and in narrow-row than in wide-row planting. The highest seed yield, 668g/square m, was obtained in 2001 with dense and narrow-row planting.
