Sažetak
Virginia type tobacco introduced in Croatia in tho 50's for the needs of tobacco production. Initially, it was planted on sandy soils and later the production spread to heavier soils in Northern Croatia, from Đurđevac to Donji Miholjac (Bašić et al., 2007). Economic effects and the size of farms are the main reasons why tobacco is often grown as a monoculture oor in a very narrow rotation. Perennial tobacco growing in a monoculture on soils prone to compaction without adding organic matter led to degradation of arable layer, what was the reason of lower yield. Often shallow soil tillage on the same depth led to increased compaction in subploughing layer, especially on ploughing depth (Birkaš, 2008). The major problem of tobacco soils in Croatia for current state of arable layer are of generic origin and the consequences of irregular managing of these soils are often deteriorated to the extent that water occasionally retain on the soil surface. Often emphasized compaction of plough and subplough layer makes the growth and development of the root system harder and it's the main limiting factor for acheiving higher yield and better leaf quality (Turšić, 1994 ; Turšić, Butorac, and Bašić, 1994). Yield and quality of tobacco, with the genetic potential of cultivar, significantly depend on the current soil fertility, applied agricultural practices and climatic conditions during the vegetation period (Hawks and Collins, 1993). Approach to managing the soil-plant system in the growing area of Virginia tobacco has to include measures such as crop rotation, calcification, appropriate fertilizer application, soil tillage, erosion, control and conservation of water in soil. Not one measure can replace the other or profitable production can be maintained until all factors which affect the productivity are well balanced.
