Effect of several nitrogen fertilizer sources on the chlorine absorption by the burley tobacco plants was investigated under the field and pot conditions. The nitrogen sources included compound fertilizer (containing 3.9% NH4-N and 6.1% NH2-N), (NH4)2 SO4, NaNO3, (NH2)2 CO and NH4 NO3. The chlorine content of leaf during growing stage was high in (NH4)2 SO4 plot, and the differences among nitrogen sources was remarkable at maximum growing stage. The chlorine content of cured leaf was high in (NH4)2 SO4 plot, and the differences among nitrogen sources was remarkable at maximum growing stage. When the (NH4)2 SO4 was applied, the total alkaloid content of cured leaf was increased and the color of cured leaf became undesirable with the increment of leaf chlorine. The yield, quality and value of cured leaf were high in NaNO3 plot, while low in (NH4)2 SO4 plot
