Abstract:
Soybean cultivar ‘Tiefeng-29’ was used as material to study the effects of planting density on growth, pod-bearing and yields. were 40,60cm, and plant spacing were 15,20,25 and 30 cm respectively. Yields and related indexes were investigated under different planting density in field culture conditions. The results showed that: plant and pod height were higher under 60cm row spacing conditions than those under 40cm row spacing conditions. Rules of row and plant spacing effects on number of node was not obvious. Numbers of branch and 100-grain weight was not affected by row and plant spacing. Pod number per plant, valid pod number and yield were significantly higher than other treatments under 40cm×30cm row and plant spacing condition. In conclusion, the proper planting density was 40cm×30cm for highest yields. Reasonable planting density was one of the key measures leading to high yields.
