Soybean Growth and Development in Various Management Systems and Planting Dates (2004, methodology): “These data correspond well with previous observations by Board (2000). Crop growth rate for Hardin was 29 and 41% lower than CX232 and Spansoy 250 at R6, respectively (Fig.”
Shade Avoidance in Soybean Reduces Branching and Increases Plant-to-Plant Variability in Biomass and Yield Per Plant (2011, background): “Fewer studies, however, have discussed the capacity for soybean vegetative stages to influence yield formation (Board 2000; Carpenter and Board 1997; Van Acker et al. 1993; Wells 1993).”
Growth and Yield Responses of Soybean to Row Spacing and Seeding Rate (2011, background): “Compensation in branch number is the main vegetative growth mechanism for yield compensation in soybean (Board, 2000) so increased branch number at the lower seeding rates increased the potential for yield compensation in this study.”
Soybean yield partitioning changes revealed by genetic gain and seeding rate interactions (2014, background): “Of interest, though, is the fact that many field research experiments have established that soybean can produce relatively similar yields from large changes in plant density (Carpenter and Board, 1997a, 1997b; Board, 2000; Edwards and Purcell, 2005; Harder et al., 2007; Lee et al., 2008).”
