Maize density is an important factor in cultivation which has significant effect on growth parameters. Newer hybrids have greater grain yield at higher plant densities than older hybrids. Differences in grain yield between older and newer maize hybrids were shown to be a function of plant population density. Optimum plant density for maximum grain yield per unit area may differ from hybrid to hybrid 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 suitable photosynthetic rates, appropriate assimilate supplies, and maintain plant growth rates attributable to enhanced mineral nutrition and water use efficiency.
