Abstract
The effect of nitrogen, phosphorus and potassium fertilizers on the chemical composition of field grown flue-cured tobacco was studied for a 3-yr period. The study consisted of 64 treatments replicated three times. It was conducted on a Soulanges sandy loam and an Uplands sand. In both soils, nitrogen and potassium showed the same trends. Nitrogen fertilizer increased nicotine content, total nitrogen and total alkaloids and reduced the percentage of reducing sugars. Phosphorus and potassium fertilizer decreased the nicotine content, total nitrogen and total alkaloids and increased the reducing sugars.Key words: Cigarette tobacco, chemical composition, alkaloids, nicotine, fertilization, Nicotiana tabacum L.
