Abstract

Sowing is the most important of all technological processes and has a serious impact on yields. Failure to observe the basic agro-technical requirements, such as optimum sowing time, proper soil preparation, sowing, sowing depth, etc., leads to irreversible losses. The seed drill, which is a modified version of a factory-made drill for punched wide-row sowing in paired rows. It is part of a machine system used to implement innovative technology in which traditional surface treatment machines are not needed. This requires that a cultivator section be included in its device to prepare the soil at the same time as sowing. Turning the seed drill into a combined machine requires it to check its performance. The inspection was carried out by examining the degree of crushing of the layer, the alignment of the profile of the treated strip and the deviation from the set depth of sowing. Each of these metrics is considered as an optimization parameter involved in three single factor experiments with a single controllable factor in them – machine speed (x).
