Maize plant densities on farmers' fields are usually lower than recommended. This may be to avoid losses due to lodging and adverse effects of environmental stresses, or to allow intercropping. Improved performance under low-N stress in maize germplasm selected for drought tolerance has been reported by Banziger et al. 1999. The objective of this research was to evaluate the response to high density planting of tropical maize populations improved for drought tolerance.Collection: CIMMYT Staff Publications Collection
