FIELD: agriculture.

SUBSTANCE: invention may be used in agricultural machine building, namely, in devices for row seeding. A ploughshare comprises a nose part, a stand and two jaws with a compactor for the central row furrow bottom. The nose part of the ploughshare is made in plan as a wedge. In the stand there are three vertical slots, and at its both sides there are side sections fixed with the possibility of adjustment along height relative to it. The latter consist of knives with slots inclined to horizon in the longitudinal and transverse planes, and furrow plows. In furrow plows there are seed channels provided, as well as compactors of side furrows bottom. Furrow plows with compactors have the possibility of displacement and fixation along slots of knives parallel to cutting edges. Furrow plows are fixed on knives by tightening nuts on rods passing through slots in knives and holes in furrow plows with the possibility of readjustment.
