Tobacco fertilization plays a key role in determining leaf quality parameters, such as leaf color, texture, hygroscopicity, combustibility (leaf-burning capacity), sugars and alkaloid contents. Tobacco needs significant amounts of potassium. The type of fertilizer used has a profound effect on the quality of the tobacco leaf. For good combustibility, good maturation and a good taste, potassium content of leaves' dry matter must be 2–2.5%, while chloride content must be below 1–1.5%. Chloride affects tobacco quality by giving it a sour taste. is a fast-growing plant, it matures within 80–150 days, after transplanting. It can be cultivated in a variety of climates, but it is sensitive to low temperatures and frosts. It prefers well drained soil with pH at 5.2-6.5.
