Recently the method of basal compound fertilizer (N : P : K = 18.2 : 9.8 : 35.0) Placement has been changed from banding to broadcasting in tobacco cultivation. The effects of the compound fertilizer placement, level of fertilizer and additional urea application on the agronomic characteristics, two chemical compositions and physical Properties of burley tobacco(Nicotiana tabacum L. cv. KB 108) were investigated at Chonju Experiment Station, Korea Ginseng and Tobacco Research Institute in 1995-1996. Six treatments consisted of (1) band (method of fertilizer Placement) + In kg/10a(compound fertilizer) + 0(additional urea applied), (2) broadcast+140+0, (3) broadcast+140+25, (4) band+180+0, (5) broadcast+180+0, and (6) broadcast +180+25. The additional urea was applied at hilling. No significant differences were detected between banding and broadcasting method of compound fertilizer Placement in field 9rowth, wield, organoleptic qualify(price Per kilogram), chemical composition and Physical properties of cured leaf, The increased compound fertilizer by 30%(40k/10a) or the additional urea application by 25kg per 10a produced slightly higher yield than the recommended amount of basal compound fertilizer without additional urea application did. It also increased the total alkaloid content of cured leaf. It is recommended that no more basal fertilizer above the recommended amount and no additional urea application are needed in burley tobacco fertilization, even though the method of basal fertilizer placement being chanced from banding to broadcasting. Key words : Nicotiana tabacum, fertilizer placement, additional urea.
