The study was conducted to determine the In vitro dry matter digestibility and In sacco rumen dry matter degradability of Cenchrus ciliaris and Panicum maximum grown under irrigation at Gode, Somali region. 2 x 3 factorial arrangements in randomized complete block design with three replications were used. Treatments were three level of fertilizer application (0, 50, 100 kg ha-1 of urea) and two grass species, which make up six treatments. The IVDMD and IVOMD increased as a result of increased urea fertilization levels. Conversely the in sacco DMD was not significantly different. The addition of urea fertilizer with the grass species in the present study improved the digestibility of the forage grasses. It could be recommended that of Cenchrus ciliaris with urea fertilizer application of 50 and 100kg ha-1, because it has more digestibility than Panicum maximum, so that agro-pastoral farmers along the Wabi- Shabelle River could increase the livestock production and productivity.
