FIELD: agriculture; engineering.SUBSTANCE: invention relates to the field of agricultural engineering, in particular to tools for introducing seeds and fertilizers into the soil. Combination opener comprises a stand with a neck, funnel and with an angle of 10…12° to each other with two discs. Fertilizer guide for inserting the main dose of fertilizers into the notch cut by the discs is fixed to the stand of the combined coulter with the reinforced stiffener of the bracket, which is installed at the place of attachment of the internal cleavers of the combined opener. Upper part of the bracket, located above the bracket attachment point to the stand, has a shelf bent at right angles to the plane of the bracket. Lower part of the guide is bent backwards in the direction opposite to the movement of the combined opener, along an arc of a circle of radius R = 300 mm and has an outlet located in a transversely vertical plane directed with respect to the longitudinal-vertical symmetry plane of the combined opener,
