It is the most widely grown commercial nonfood plant in the world (Akehurst, 1981). The botanical genus Nicotiana contains over sixty four species. Nicotiana tobaccum is the source of commercial tobacco, which is a member of the family Solanaceae and it is grown as an annual crop for its leaves. Tobacco is the common name of the plant Nicotiana tabacum and to a limited extent of Nicotiana rustica. Cigarette tobacco production in Sri Lanka is done by the registered farmers of Ceylon Tobacco Company for a pre-trade agreement. Nitrogen fertilizer plays a crucial role in tobacco production and large and quality production keenly depends on applied nitrogen fertilizer. However, existing nitrogen fertilizer levels have not fully met the yield forecasting and other cost compensating objectives. Therefore, this experiment was conducted to investigate the effect of nitrogen fertilizer level on the nicotine development of flue cured tobacco and to investigate the best application time of fertilizer on the vegetative growth of flue cured tobacco.enExport AgricultureGeochemistryFood ScienceOther
