Crop rotation, a plant population and a size of the pre-cleaned seed were monitored during the production of sugar beet seed crop over a 15-year period. Sugar beet seed growers were divided into four groups based on the crop rotation used. In all of the rotations, wheat was the preceding crop. Wheat is considered a good preceding crop for sugar beet, because it is harvested early, leaving sufficient time for two to three ploughings and a good seedbed preparation. However, the observation of all the crops that preceded either wheat or sugar beet crop on the plots, shows that maize ranks first as the most commonly used preceding crop (33-40%). Of the three factors observed in the present study, only the seed size showed statistically significant differences among the treatments. No significant differences were noted for the other two factors. The different crop rotations had the greatest effect on the seed size in the case of the 3.5-4.5 and 4.5-6.0 mm seed fractions.
