This experiment was carried out to determine the effect of nitrogen application level of cattle sluny(T1:150, T3:250, T53.50 kglha) and chemical fertilizer(T2:150, T4:250, T6:350 kg/ha) on the growth characteristics, dry matter yield and chemical soil property of Sorghum-Sudangrass hybrid [Sorghum bicolor L. Moench]. The results obtained are summarized as follows: Mean stem diameter was significantly increased by increasing nitrogen application level of cattle slurry and chemical fertilizer. Especially, T6 treatment was the highest as 11.1 mm, while T1 treatment w a the lowest as 0.3 mrn. According to the same level of nitrogen application, cattle slurry treaunent(T1, T3 and T5) were showed a lower mean stem hardness than chemical fertilizer treatment(T2, T4 and T6). Especially, T3 treatment was the softest at 0.7 kg/$cm^2$. The dead stubble and tiller number were increased by increasing nitrogen level of cattle slurry and chemical fertilizer(P<O.Ol). 'Ihe tiller number was the highest at T6 treatment(3.7 per plant), but dead stubble was the highest at T5 treatment(3.7 per plant), but dead stubble was the highest at T5 Treatment(l1.4 % per hectare). In view of total fresh weight and dry matter yeild, T6 treatment was the highest as 118,163, 20, 627 kgha respectively(P<O.Ol). In the palatability of Holstein, T5 treatment in spite of high nitrogen level showed high palatability at 938, but T6 treatment showed low at 51%(P<0.05). In the palatability of deer, T3 treatment was the highest as 1006, while T6 treatment was the lowest as 728. pH and total nitrogen showed higher cattle slurry treatment ( T I , T3 and T5) than chemical fertilizer treatment (T2, T4 and T6) at the same nitrogen level. Also, pH and total nitrogen of T5 treatment showed the highest at 6.7 and 0.198% respectively. Ca, Mg and K Showed higher cattle slurry treatment(T1 and T5) than chemical fertilizer treatment(T2 and T6) at the same nitrogen level.
