Abstract

A completely new design of the wave roller is presented, which has no analogues produced by the industry. As a result of research on barley crops, it was revealed that the optimization criterion kse after treatment with the developed wave roller is 0.81. The density and aggregate composition of the soil in all parts of the field (in the ridges and in the troughs of the wave relief) fully meets the agrotechnical requirements. In the area after treatment with a serial roller KKZ-6, the optimization criterion kse = 0.67, which is significantly lower than that of the proposed wave roller. At the same time, soil clods were found on the soil surface, the size of which exceeds 50 mm, which does not meet the agrotechnical requirements for rolling. Studies conducted under production conditions made it possible to determine that the rolling of barley crops with the proposed wave roller increased its yield to 47.2 centners per hectare (by 12.4%) compared to 42 centners per hectare after rolling the crops with ring-toothed rollers KKZ-6.
