FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine building, particularly to ploughshares for sowing grain crops in arid regions. Ploughshare comprises a housing, two discs installed at an angle of 18° to each other. Between the discs there is a plate for formation of a seed bed. Behind the ploughshare, a rob coverer is attached to the ploughshare housing along the trace of a seed row through the shaped plate.
EFFECT: such a design provides higher yield of grain crops.
