Forage and nitrogen content responses of common buffelgrass (Cenchrus ciliaris L.) to nitrogen (N) and phosphorus (P) fertilization were evaluated for two successive years in the UAE. Treatments consisted of five rates of N (0, 250, 500, 750 and 1000 kg ha-1 yr-1) and four rates of P (0, 200, 400 and 600 kg ha-1 yr-1), applied via weekly fertigation. All N fertilizer treatments resulted in significant increase in forage dry yield, relative to control. However, no yield increase was observed from N treatments greater than 250 kg N ha-1. There were neither significant yield responses to P fertilization treatments over the two years of the study, nor significant N-P treatment interactions for yield. Forage N concentration progressively increased with increasing levels of N fertilizer, reaching maximum levels under the 1000 kg ha-1 N treatment. A seasonal pattern of forage N concentration occurred, being higher in winter and lower in summer.
