Sažetak

The most significant factor for controlling root size of red beet is likely to be the density of seed plantings. Most red beet is produced by direct sowing with precision drills at an in-row spacing of 5 to 10 cm, aiming at 30 to 70 plants per m2. The purpose of this research was to examine the effects of varied forward speed on in-row seed spacing distribution accuracy of red beet using different types of precision drills. It was found that an increase in the drill operating speed decreases drilling precision. The best in-row seed spacing distribution accuracy was determined at the speed of 0,83 m/s with the pneumatic feed precision drill operated suction system, when 83,1 % of seeds were laid at the 0,5÷1,5 of the theoretical seed spacing. Inferior results were obtained with the belt feed mechanism at an operating speed of 1,81 m/s.
