The aim of the study was to assess the quality of sowing hemp seeds of the Finola variety using a precision seeder with a pneumatic sowing system from Gaspardo. During the study, the influence of selected operating parameters of the tested prototype (aggregate) for cultivation and sowing on the quality of its work (sowing uniformity) was assessed. The implementation of the assumed objective and scope of the study required field tests, which were carried out in Adamów near Zamość. Evaluation of the quality of sowing hemp seeds using a pneumatic precision seeder included in the sowing unit was carried out based on the methodology of testing precision seeders and guidelines included in the literature. During the seeder study, the influence of the arrangement of plants after emergence in a row on a section of 5 m was examined in five repetitions at the following unit speeds: 5, 6, 7 and 10 km·h -1 . It was found that with the increase of the working speed of the seeder and the rotational speed of the sowing disc, the quality of seed sowing deteriorated. The conducted scientific research related to the improvement of precision sowing techniques, including their in-depth theoretical analysis and experimental studies, will allow for further extension of this research topic. Analysis of the variance of independent variables, i.e. the working speed of the seeder and the sowing disc, showed their influence on the shares of single, double and pass sowings at the given parameters. The interaction of these variables is also important. As a result of the research work carried out, guidelines for practice were developed regarding the appropriate operating settings of the bleaching unit of the tested precision seeder in relation to sowing the selected seed species.
