Abstract

The past few years, Alliance One Tobacco Company made serious efforts for restarting the semi oriental tobacco production in Republic of Macedonia. To improve the sort randman the Scientific Tobacco Institute created new semi oriental tobaccos with high yield and quality. One of them is the variety Otlja-Zlatovrv. The main aim in this investigation is to study the effects of fertilization and irrigation of the production properties on semi oriental tobacco variety Otlja-Zlatovrv. The results of this investigation will be great opportunity for production of this tobacco type. Three-year field experiments were set up on а deluvialcolluvial soil type in 12 variants with three replications. The trial was bifactorial, with three rates of nitrogen fertilizer (25, 35 and 45kg N/ha) and two irrigation regimes (45 and 60% FC). The obtained results confirm that fertilization and irrigation have positive impact on the production properties of this tobacco. The yield has increased by 89.98% (var. 12), the average price by 13.57% (var.7), and the income per unit area by 109.05% compared to the control variety. Fertilization and irrigation have significant impact on reduction of nicotine and proteins and on increase of soluble sugars.
