The article presents the results of the experimental studies on determining the optimal values of the roller of the plowed land and selecting its type on the basis of this. In experimental studies, the provision of complete processing of the field surface is ensured mainly by the selection of the type of roller and the planer for installation on the roller, in order to obtain the required level of moisture for seed germination according to agrotechnical requirements. it is noted that there are gear-plate, rod working parts. In order to verify these obtained results, we made plate, gear-plate, and rod coils, which have a constant diameter, and conducted experimental studies using them. In experimental studies, after using different rollers with a constant diameter, the influence of soil compaction, density and tensile strength was studied. In order to reduce the influence of various variable factors on the obtained results, the experiments were carried out on a specially prepared agro background, that is, it was first plowed and then leveled.

In order to test the theoretically based parameters of the roller selected for conducting experimental studies in field conditions, the bases of the roller with a coverage width of 1.5 m and fixed-diameter bases with slats, toothed-slats, and wire plates to be installed on them were developed. released and prepared.

Based on the results of experimental studies, the following can be noted: in order to ensure that the compaction quality and density of the soil meet the agrotechnical requirements, and to ensure that the rolling resistance is minimal, it is necessary to have a gear-plate roller.

In this article, the influence of the relative vertical pressure force applied to the roller of the combined plowing machine on plowed land on its performance was determined based on theoretical and experimental experiments, and the results were determined.

Plastic materials play a crucial role in modern European agriculture, offering solutions that enhance productivity, efficiency, and sustainability. This study provides a comprehensive review of the current utilization of plastic materials in agricultural practices across Europe and explores prospective developments shaping the future of their application.

Tomato is a heat-loving annual crop that belongs to the nightshade family. Seeds begin to germinate at temperatures no lower than 10–15 °C. At a soil temperature of 15 °C, 14–22 days pass from sowing to emergence, and if it is below 10 °C, the seeds do not germinate at all.
