Zusammenfassung:The precision seed drills significantly improve the competitiveness of farms, in terms of sowing quality and yield. This paper refers to the field performance of the tractor-seed drill system and the seed spacing uniformity with reference to three precision drills with 4, 6 and 8 sowing units, respectively. The tests have been conducted using graded maize and sugar beet seeds, according to ISO 7256-1:1984 standard, under three speed conditions (5.0, 6.5 and 8.0 km h-1). The seed drills showed high values of the quality of feed index (> 90%) even at the higher speed. The multiples index and the miss index were very low.
