Comparative Technological Study of the Tobacco of Burley Variety Group Grown in Bulgaria

摘要

It is known that the variation in tobacco indicators is mainly determined by the harvest belt (the biological factor) and the crop (the climatic factor), and less by the region and microregion of growing (soil-climatic and agrobiological factors). It has been established in a research of the quality of Burley tobacco, produced in different regions in Bulgaria that the Bulgarian Burley tobacco corresponds to the type according by general quality, but it has some specific peculiarities due to the specific conditions of growing. The purpose of the present study is the comparative technological investigation of the tobacco of Burley variety group, grown in different regions in Bulgaria, with the view of establishing the typical for the variety high quality. The samples taken from different regions of the country have been analyzed with respect to the main technological indicators, describing their quality. The results obtained show that there are no clearly expressed differences as to the quality between the Burley tobacco variety produced in the different regions in Bulgaria. By complex quality estimation they suit the requirements for this type of tobacco, and more specifically with respect to the objective chemical indicators. When applying appropriate agricultural equipment, as well as under favourable climatic conditions (crop), they possess qualities that meet the purchasers' requirements towards this tobacco type according to its consumption.
