ABSTRACT

The objectives of present study were to increase understanding of how NAR and LAI contribute to CGR and grain yield equilibration across plant populations. Maximum and minimum grain yields of 433.2 and 262.9 g m 2 were attained by 100 and 20 plants m 2, respectively. However, no grain yield significant differences were obtained among 60, 80 and 100 plants m 2. Greater leaf expansion rate during emergence to early flowering (R1) and greater light interception per unit LAI during early flowering to early seed filling (R1 to R5) for low vs. high plant population caused to equal LAI at R1 and equal NAR during early reproductive among 60, 80 and 100 plant populations, resulting CGR equilibration during early reproductive and similar pod per plant and grain yield between these plant populations.
