%X the objective of this study was to determine the effect of the population density on the grain yield of nine tropical maize genotypes (zea mays l.). a study was conducted in 2005 at the experimental station of the universidad ju芍rez aut車noma de tabasco, centro municipality, tabasco. a randomized complete block experimental design with four replicates and a split plot arrangement was used. the big plots contained population densities of 44 289, 53 200 and 66 500 plants ha-1, and the small plot contained population densities of 21, 22, 23, 25, 32, 43, 49, the hs-3g hybrid and the vs-536 variety. significant differences among densities were recorded only for grain yield (p < 0.01), genotypes for plant height (p < 0.01), ear height (p < 0.01), and days to flowering (p < 0.01). the density of 66 500 plants ha-1 presented the greatest grain yield (p < 0.05). the interaction between population and density was non significant. the genotypes with the best grain yield were populations 21, 23, 25, 43 and hs-3g.
