Fertilizer guide is mounted on single disk shank and is provided with mineral fertilizer divider positioned immediately after protecting shield. Divider is made in the form of cone having certain angle at its apex. Divider cone apex is positioned strictly in plane of symmetry of fertilizer guide. Seed guide is made in the form of two branch pipes, each positioned on individual single disk shank. Single disk shanks are positioned so as to allow regulation of depth and width of apparatus stroke independently from one another within wide range of depths and widths.
