Maize density is an important factor in cultivation which has significant effecton growth parameters. Newer hybrids have greater grain yield at higher plantdensities than older hybrids. Differences in grain yield between older and newermaize hybrids were shown to be a function of plant population density. Optimumplant density for maximum grain yield per unit area may differ from hybrid tohybrid on account of significant interactions between hybrids and densities.Modern hybrids have shown tendencies to withstand higher levels of stress (i.e.-low N, high plant densities), which allow them to better sustain suitablephotosynthetic rates, appropriate assimilate supplies, and maintain plant growthrates attributable to enhanced mineral nutrition and water use efficiency.
