Experiments to determination of suitable plant row spacing densities and fertilizer dosages for the maize hybrid LVN102 were exposed in The Western Hinglands Agriculture and Forestry Science Institute at Hoa Thang, Buon Ma Thuot City, and Dak Lak province in Summer Autumn 2013. From the research results of 6 different densities showed that the highest real yield of LVN102 was a density of 59 thousand plants/ha (60  28cm), followed by 55 thousand plants/ha (65  28cm). In the same amount of fertilizer P2O5 and K2O but at 200 N proteins had a higher yield compared with 180 N and 160 N. The maize LVN102 was harvested the highest real yield (10.12 tons/ha) at a density of 59 thousand plants/ha (60  28cm) and fertilizer dosages was 200kgN + 100 kg P2O5 + 80 K2O + 2.500 kg of microbial fertilizer.
