Conteúdo: 	Sixty-four maize hybrids were evaluated in 2007 in Teresina, PI, under two types of
irrigation management: no water deficit and water deficit during the reproductive phase. With randomized blocks, with three repetitions experimental design was used. The average grain yields without water deficit and with water deficit were, 4,504 kg ha-¹ and 483 kg ha-¹, respectively; With water deficit, 18 hybrids produced above the average, out standing 30F53, HTMV1, HTMV2, 159, 26 and 155 with productivity 2,228 kg ha-¹, 1,922 kg ha-¹, 1,288 kg ha-¹, 1,285 kg ha-¹, 1,232 kg ha-¹ and 1,040 kg ha-¹ respectively. Without water deficit, 31 genotypes produced above the average, with
emphasis on hybrid 30F53, 151, 101, BRS 1030 and the 3 with 6,497 kg ha-¹, 6,489 kg ha-¹, 6,430 kg ha-¹, 6,411 kg ha-¹ and 6,199 kg ha-¹ respectively. Without water deficit the grain productivity was 800% higher than with water deficit. The hybrid 30F53 was the most productive under water deficit, with productivity higher than 2,000 kg ha-¹.
