The objective of this study was to investigate the effects of planting date and spacing in field performance of five soybean varieties different in plant types. The results obtained were summarized as follows: 1. Number of days of flowering, fruiting period, and maturity were reduced with delayed planting dates. Number of days to flowering of late maturing varieties was more affected than the early maturing varieties by delayed planting, but the influence was less remarkable than those to maturity date. There was significant differences between earlier and later plantings in such characters as seed weight, plant height, number of nodes and pods per plant. However, the reverse was true for the variety Clark and yield was remarkably reduced with later planting as compared to other varieties. 2. Plant spacing did not significantly affect on yield, seed weight and number of nodes per plant. Although plant height, number of branches and pods per plant were affected by spacing, the influence was less than those of planting date in these characters. 3. Maximum yield was observed in planting on May 21 and optimum spacing for high yielding was 60㎝×10㎝ in this experiment. 4. Interaction between planting date and spacing was closely related to yielding and it was considered that proper planting date and spacing were able to result in higher yielding.
