Abstract
The field experiment was conducted to study the effect of different potassium fertilization rate on (agronomic) characters of flue-cured tobacco. The results showed that under the same dose of nitrogen (N) and phosphorus ((P_(2)O_(5))) fertilizer with 120 and 240 kg/ha respectively, the girth and dry matter weight of stem significantly increased when potassium fertilization rate increased from 240 to 480 kg/ha K_(2)O, but the increase of weight and length of (lateral) roots was not significant, as well as the leaf area, when potassium was applied over 360 kg/ha K_(2)O.
