This paper presents the long-term results relating to the influence of different crop rotations and tobacco monoculture upon the chemical composition of flue-cured tobacco leaf. As a key crop, tobacco is included in all crop rotations. Considering the obtained results in the particular year’s tobacco growing in monoculture or in crop rotation mainly had significant effect on nicotine content in tobacco leaf including a 10-year average. A similar trend was also determined for the content of proteins. The content of total nitrogen and reducing sugars was mainly affected significantly by crop rotation as regards the particular years. Calcium and potassium ratio was also unfavorable, although both of them were significantly influenced by crop rotation. The same is true for magnesium in the particular years.
