Fig. 7 Relative growth rate (RGR), net assimilation rate (NAR), and light interception efficiency (LIE) for soybean grown in low, medium, and high plant populations near Baton Rouge, LA, in 1996. Low population = 80000 plants ha^-1; medium population = 145000 plants ha^-1; high population = 390000 plants ha^-1. *Low and medium plant populations are significantly different according to LSD (P < 0.05). Medium and high plant populations are significantly different according to LSD (P < 0.05). Low and high plant populations are significantly different according to LSD (P < 0.05)
