Abstract:
A appropriate planting density and feasibility of narrow-row spacings for higher yield in soybeanwere discussed by investigating the effects on agronomic, physiological characteristics and yield in two highoil varieties Liaodou 11 and Liaodou 14 under different spacings. With the increase of planting density ,plant height was increased, while node number , branch number and pod weight per plant were decreased,and the 100-grain weight was declined slightly.Although LAI was increased , the leaf area per plant anddry matter accumulation was decreased. Significant yield differences were observed among varieties anddifferent planting density , but no significant differences were found under different row spacings.
