In order to determine the optimal variation of the seedbed preparation for sugar beet seed, a large-plot trial was conducted at Bački Petrovac (Serbia) from 2003 to 2005. The trial included the following variants: control (ploughing open furrows during winter); 1) levelling and pulverising in spring; 2) three pulverisations in spring; 3) two pulverisations and one smooth rolling in spring; 4) disking, seedbed preparation, and pulverisation in spring; 5) disking and two pulverisations in spring; 6) disking and pulverisation in spring; 7) standard (disking and levelling in fall, pulverisation in spring). After three years, the most favourable soil structure, with the highest percentage of macro-aggregates of 0.25-5.0 mm, was achieved by the application of the standard variant of the seedbed preparation. The preparation variant 6 (disking and pulverisation in spring) resulted in the poorest soil structure, containing macro-aggregates larger than 10 mm. The highest germination of sugar beet seeds in field was obtained with the standard preparation variant (disking and levelling in fall, pulverisation in spring), followed by the variant 1 (levelling and pulverising in spring), variant 2 (three pulverisations in spring), variant 3 (two pulverisations and one smooth rolling in spring), variant 4 (disking, seedbed preparation, and pulverisation in spring), variant 5 (disking and two pulverisations in spring), and the variant 6 (disking and pulverisation in spring).
