The influence of planting distances (PD) and nitrogen fertilizers (NF) on growth of maize yield, were tested at two PD of 15 and 20 cm, and three NF levels 100 ,120and 140 kg.ha-1. The experiments were conducted in a factorial experiment under complete randomized design with three replications. The results showed that the PD of 20cm was significantly better than the PD of 15 cm in all studied conditions. The RDW, NGE, 1000-WG, PVI and TGY , 58.17 g , 620 grain.ear-1, 507g , 72.03cm, and 5.851 ton.ha-1, the treatment NF of 140 kg.ha-1cm was significantly superior to the levels of 100 and 120 kg.ha-1 in all studied conditions. With the exception of the physical soil characteristics represented by the density and porosity of the soil, best results were achieved with a planting distance of 15 cm and a nitrogen level of 100 kg.ha-1
