\textbf{Abstract}
\begin{abstract}
\normalsize{
An experiment was conducted to investigate the yield performance and fodder quality of four cultivars of Napier grass in the Savelugu District of Northern Ghana. The randomised complete block design (RCBD) was used for evaluating the yield performance and the 4 (cultivars)*3 (botanical fraction) factorial in completely randomised design was used for the fodder quality assessment. Three of the cultivars; 16837, 16798 and 16840 were obtained from the International Livestock Research Institute (ILRI) and the Local was from the environs of Kumasi in the Ashanti Region of Ghana. They were all preserved at the herbarium of the Department of Animal Science of the Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi. The biomass yield, tiller number, plant height and leaf: stem ration did not differ ($p > 0.05$) by cultivar. The biomass yield (DM kg/ha) ranged between 1354 to \mbox{3339\,kg} for the 16798 and Local respectively.  The highest ($p > 0.05$) tiller number was obtained in cultivar 16798 whilst the highest ($p > 0.05$) plant height was reported in cultivar 16840. Plant height was positively correlated ($p < 0.001$) with biomass yield. The cultivar by botanical fraction interaction and min effects did not affect the nutrient composition except the hemicellulose.  The highest ($p < 0.042$) hemicellulose was obtained in the leaf fraction of the local cultivar. The stem fraction for all the cultivars was consistently ($p > 0.05$) lower in crude protein concentration with the Local having the least. In conclusion, the study revealed that the Local cultivar compared favourably with the improved cultivars from ILRI in terms of yield and fodder quality.  }
