Productive performance of maize crop irrigated with and without water deficit in different plant arrangements.
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.
