The cultivation of Napier grass (Pennisetum purpureum Schumach) for the experiment was conducted at FASA Agropark, Pengkalan Chepa, Kelantan and the laboratory analyses were done in the FASA Taman Bendahara laboratory during October 2010 to March 2011. Growth, yield, dry matter and crude protein content of Napier grasses were evaluated under different level of manuring treatments. The treatments were 0 (as control), 150 and 300 kg N ha-lthat were supplied with sheep manure. The grass was not affected (p>0.05) by level of nitrogen. The overall yields were showed much lower and with 6299 kg per hectare and 3323 kg per hectare for first and second cultivation respectively. The number of tillers and crude protein content showed significant differences (p<0.05) for the first cultivation. In contrast, there were no statically significant difference (p>0.05) in the growth of plant height and dimension of leaves among the different treatment groups for the two cultivations. However, there were strong positive correlations (r = 0.960) between leaves length and leaves breadth. These insignificant results could possible attributed to soil fertility, flood and planting distance.
