Fertilization of Virginia tobacco with compound fertilizers. I. Growth, yield and quality
Radka Bozhinova
Abstract: Bozhinova, R. (2019). Fertilization of Virginia tobacco with compound fertilizers. I. Growth, yield and quality. Bulgarian Journal of Soil Science, Agrochemistry and Ecology, 53(1), 21-26
A field study was conducted in 2017 and 2018 to determine the effects of two compound fertilizers NPK (15:15:15) and NPK (12:12:17) and ammonium nitrate on growth parameters, yield and quality of Virginia tobacco. The experimental design was a randomized complete block replicated three times.
When Virginia tobacco was grown on Cleyic-Chromic Luvisol with low available soil phosphorus,the application of compound fertilizers significantly increased the dry weight per unit leaf area as compared to fertilization with ammonium nitrate. Different treatments had no recordable influence on
the growth parameters (plant height, number of leaves, dimensions of leaves and leaf area). The use of a compound fertilizer NPK (12:12:17) slightly improved yield and leaf quality (as determined by the percentage of first grade dried tobacco), but no significant differences was determined between treatments.
