| Title : | SOME MANUFACTURING PROPERTIES OF SEMI-ORIENTAL TOBACCOS BRED IN THE REGION OF PRILEP, WESTERN MACEDONIA |
| Abstract : | The need for this research was imposed by the increased interest of tobacco companies to restart production of semi-oriental tobacco in R. Macedonia. The aim of the research was to study the impact of agrotechnics on some manufacturing properties of semi-oriental varieties Otlja O9-18/2 and Otlja-Zlatovrv produced in agro-ecological conditions of the Prilep production region. Three-year trial was set up on deluvial-colluvial soil type in 12 variants with three replications. The trial was bi-factorial, with three rates of nitrogen (25, 30 and 45 kg N/ha), constant amount of phosphorus (80 kg/ha) and potassium (100 kg/ha) and two irrigation regimes (45 and 60% FC). The following characteristics were subject of investigation: dry tobacco yield per hectare, plant height, leaf number per stalk and average length/width of the fifth, tenth and fifteenth leaf. The obtained results confirm that fertilization and irrigation have positive impact on the manufacturing properties of both varieties. Compared to the check variety, the yield was increased by 86.89% in Otlja O9-18/2 and 89.98% in Otlja-Zlatovrv variety. Fertilization and irrigation have statistically significant impact on the increase of plant height in all three years of investigations. Regarding the character leaf number per stalk, the applied agricultural practices did not show statistical significance at 5% only in 2008. Fertilization and irrigation have positive impact on increase of the leaf length, width and their average relative surface. Based on the results it can be concluded that the manufacturing properties of semi-oriental tobacco can be managed by application of proper agrotechnics. It can be concluded that the yield and quality of semi-oriental tobacco can be improved by application of proper agrotechnics |
