The management of spatial arrangement in the maize crop by alteration in the spacing between rows and sowing density has been appointed as one of the most important agronomic practices to maximize the grains yield. The objective of this study was to evaluate the behavior of maize in relation to the reduction of row spacing and the different sowing densities during the off season in the Cerrado region. The experimental design was randomized blocks in factorial scheme 2 x 5 with four replications. The treatments consisted of two spacing between rows (0.45 m and 0.90 m) and five sowing densities (40,000, 55,000, 70,000, 85,000 and 100,000 plants ha-1). It was not found significant response for the reduction of row spacing for the assessed characteristics in maize crop. The increase of sowing density resulted in plant height, number of grains per row and number of grains per ears reduction in the maize crop; however, there was an increase in yield until the density of 100,000 plants ha-1.
