Sažetak
Since vegetable crops are characterised by a small seed size, a large number of plants per unit area and a shallow drilling depth, seed drills have to satisfy all these requirements so as to enable good-quality drilling. Uniformity of seed size and shape has a considerable effect upon the drill precision, notably on the performance of drills with a mechanical drilling unit. The best intra-row distribution of parsley seeds was recorded at the speed of 1.8 km/h. At this speed 80.4% of seed was sown at the required spacing. At 2.4 km/h, 79.3% of seed was sown, 79.4% of seed at a speed of 3.6 km/h, reducing to 76.6% at a speed of 5.2 km/h. Research results show that satisfactory drilling results were achieved at speeds ranging from 1.8 to 5.2 km/h.
