The effects of five levels of nitrogen (N) fertilization (0; 60; 120; 240 and 480 kg of N/ha) upon Buffel grass (Cenchrus ciliaris, L.) performance were evaluated. A completely random design with three replicates was used. Dry matter yield of aerial portion (DMYAP), dry matter yield of roots (DMYR), leaf/stem ratio (LSR), number of tillers (NT) and water use efficiency (WUE) were measured. The results showed a linear effect (P < 0.002) on DMYAP and DMYR and linear and quadratic effects (P < 0.02) on NT and WUE. LSR was not influenced by the nitrogen fertilization. Overall, it could be concluded that Buffel grass responded positively to nitrogen fertilization.
