Effects of soil tillage on the yield and quality of tobacco in Croatia

The effect of soil tillage on the yield and quality of flue-cured tobacco was studied from 1988 to 2001 at the Experimental Station of the Tobacco Institute Zagreb in Croatia. The trial soil was a Luvisol with an acid reaction and a low content of colloids and organic matter. There were three treatments in the experiment: autumn ploughing, spring ploughing, and autumn ploughing + chisel ploughing in spring. The treatments were arranged in random blocks with four replications. Soil ploughed in both autumn and spring gave higher yields of flue-cured tobacco in comparison with autumn ploughing alone. Soil ploughd only in autumn became compacted due to settling during the winter and spring because of the unstable structure and unfavourable texture.
