Bozukov, H., Kasheva, M., Docheva, M. & Kochev, Yo. (2023). Quality parameters of applicant tobacco variety Virginia 0842. Bulg. J. Agric. Sci., 29(4), 657–661
This scientific research was conducted in the period from 2019 to 2022, in the district of Plovdiv and Pazardzhik, under production conditions. All biological parameters were determined and assessment was made of the basic quality parameters of the tobacco raw materials, produced from the new line of large-leaf tobacco Virginia 0842. The basic physical parameters of raw tobacco were established. The basic chemical parameters of tobacco were determined: nicotine, soluble sugars, total nitrogen and ash. The results show high nicotine values (1.02 to 3.78) in Virginia 0842, in comparison with the reference variety Virginia 0514. Total sugar values in Virginia 0842 from the three crops are very high in both classes (11.10 – 25.52). Ash content is low – ranging from 8.01% to 15.09%; this shows high leaf content. Total nitrogen for Virginia 0842 ranges from 1.52 to 2.85 % and it is from 3.04 to 3.61 for the reference variety. The free burning rate of Virginia 0842 tobacco was determined (2.74 to 2.85 mm/min).
