The experiment consisted of two plant populations of 53,333 plantha-1 and 88,888 plantsha-1 as main plot and 8 recently developed drought–tolerant maize-hybrids M0826-7, M0926-8, M1026-10, M1026-13, M1124-4, M1124-10, M1227-12, M1227-14) and 2 widely cultivated commercial hybrids (Oba-98 and Oba super-1) as sub-plots laid out in a randomized split-plot design and replicated three times. Plant populations at both locations significantly affected phenological responses. Increasing plant population significantly decreased the phenology of maize-hybrids, which showed early maturity, and better adaptation of hybrids to increased plant population. However recent hybrids were more tolerant to high plant population than the commercial hybrids. Therefore the recently released hybrids were more adapted to biotic stress.   Key words: plant population, maize-hybrids, phenology.
