Summary: The objective of the present study was to evaluate the effects of row spacing and planting density, under different water regimes, on dry grain production of the maize hybrid AG - 1051, in Teresina, Piauí. Two experiments were conducted with the use of a conventional sprinkler system for irrigation, being one with 100% and the other with 50% crop evapotranspiration (ETc) replacement. A randomized block experimental design was used, in a 5x2 factorial scheme, combining five planting densities (PD) (20,000; 40,000; 60,000; 80,000; and 100,000 plants ha-1) and two spacings between rows (RS) (0.5 and 1.0 m), with four replications.
