Experiments to determination of suitable plant row spacing densities and fertilizer dosages for the maize hybrid LVN111 were exposed in Dong Hoa Commune, Trang Bom District, and Dong Nai Province in the Summer Autumn 2013. From three row spacing of 60cm, 65cm and 70cm, the results showed that the highest real yield was row spacing of 60cm, followed by 65cm and 70cm respectively. The maize LVN111 reached the highest yield (10.10 tons/ha) with a density of 66,600 plants/ha (60  25cm) and fertilizer dosage was 200 kg N + 100 kg P2O5 + 80 kg K2O + 2.500 kg of microbial fertilizer.
