Abstract: The accumulation of main macro- and microelements by new Oriental tobacco varietiesKrumovgrad 944 and Krumovgrad 17 was observed in field experiment set on Leached Cinnamonic Forest Soil (Chromic Luvisol). Plants were spaced at 10; 12, 5 and 15 cm in rows and 55 cm apart. The random samples of sun-cured leaves (middle and upper leaves) were analyzed for determination of nutritional elements’ concentration in the plant tissues. Results indicate that
variety and distance between plants in the row had little effect on content of N, P, K, Ca and Mg in oriental tobacco leaves. The difference was noted in microelements accumulation among two tobacco varieties.
