The Meatring of Beetroot Seeds Sowing Quality with the Use of Precision Seed Plate Planter
This paper presents the results of the laboratory research concerning assessment of the quality of sowing Czerwona Kula beetroot seeds by means of S071 Kruk seeder. The research showed significant influence of the seeder operating speed on the quality of sowing, expressed in percentage of single, double and skipped plants. The most regular dosage of seeds in a row was obtained at the seeder's operating speed of 0.6 m·s-1 and sowing disk's peripheral speed of 0.6 m·s-1. Increase of the seeder operating speed above 0.6 m·s-1 caused deterioration of the beetroot seeds distribution in a row. Thus, it can be concluded that the seeder operating speed significantly affected the quality of Czerwona Kula beetroot sowing.
The objective of the research was assessment of the sowing quality of radish seeds with the sowing unit of “MAX PNEUAMTIC” S 156 pneumatic seeder. Tests were carried out on the original laboratory stand. They proved that at the assumed range of the working speed within 2.5 to 4.0 km·h−1 and rotations of the sowing disc between 23 and 37 rot·min−1, the most favourable results concerning precision of seeds spacing in a row were obtained at the speed between 2.5 and 3.0 km·h−1. The increase of the speed above 3.0 km·h−1 caused deterioration of the seeds sowing quality through statistically significant reduction of the single sowing participation and the increase of the empty sowings participation.
Results of laboratory tests on the sowing quality of Vistula parsley seeds with a working section of a seed drill by Weremczuk company Max Pneumatic S 156 model with a pneumatic sowing system were presented. Tests of the sowing section of a seed drill were carried out in laboratory conditions on a special stand. They showed that the seed drill speed and rotations of the sowing disc have a significant impact on the sowing quality expressed with participation of single, double sowing and passes. The most favourable results at all set distances between seeds in a row were obtained with a seed drill speed of 1 km·h−1. On the other hand, the increase of the working speed of a seed drill and rotations of a sowing disc influenced significantly the deterioration of the sowing quality.
