Abstract
The aim of the studies was to compare the effects of different plant spacing on tobacco yield and market value as well as important qualitative features of four varieties representing type Virginia: Wiślica, Wisana, Wika and Wiecha. The field experiments designed as the randomized blocks were carried out in the years 1997-1998. The qualitative analysis of tobacco leaves included assessment of composition of soluble carbohydrates and true proteins, weight of 1 dm2 of dried leaves and amount of the main vein tissue (%) within the foliage. Plant spacing was found to influence considerably both yield and leaf quality of Virginia tobacco. The yield and market value of plants grown at the spacing 70 x 40 cm were higher than those of plants grown at 90 x 40 cm. However, the leaves of higher quality, characterized by a high content of carbohydrates and a relatively low content of proteins, were produced by the plants grown at 90 x 40 cm. Based on the results concerning the yield and quality of raw material, two tobacco varieties: Wiślica and Wika can be recommended for cultivation.
