Sažetak
From the wider context of broadly conceived long-term experiments with growing tobacco in monoculture and different crop rotations, this paper presents results on the achieved yields and major yield components for crops grown, as well as participation of particular tobacco classes. In addition to tobacco monoculture, at first only fertilized and later on also unfertilized, as the key crop, different types of crop rotations included, besides tobacco, the following crops: winter wheat, maize, soybean, oil-seed rape, and red clover. Experiments involved two 2-year and two 4-year crop rotations, and a 3-year, a 5-year, and a 6-year crop rotation each. Experiments were set up on luvic semigley on multi-layered Pleistocene sands. Average 10-year results point to the advantage of crop rotation over monoculture for tobacco leaf yields. Influence of different crop rotation types upon yields of other crops was variable, tending towards higher values with increasing the number of crops in rotation. Values obtained for yield components should be considered from two aspects. Namely, some of them were primarily genetically conditioned while the others were influenced by ecological factors, including crop rotation as an overall biological buffer. With regard to participation of quality classes (I-III), growing of flue-cured tobacco in crop rotation represents a great advancement relative to its growing in monoculture, even in a narrower crop rotation.
