Increasing of productivity of dwarf napiergrass as ruminant feed could be conducted with a mixed cropping system with legume such as centro. The object of this study was to determine the growth character of dwarf napiergrass planted with centro and distance of 0.5 m. The research was carried out for 4 months, using 5 treatments and 4 replications so that it requires 20 plots. The treatment consisted of P1 as 100% of dwarf napiergrass; P2 as 70% of dwarf napiergrass and 30% centro; P3 as 50% of dwarf napiergrass and 50% centro; P4 as 30% of dwarf napiergrass and 70% centro; and P5 as 100% of centro, respectively. The results showed that the treatment had not significantly affected (P > 0.05) growth characters neither plant height and tiller number of dwarf napiergrass, plant length and branches of centro, nor chlorophyll. Nevertheless, the treatment showed a tendency increased by the increased of measurement interval, not only dwarf napiergrass but also centro.
