FIELD: agriculture. SUBSTANCE: drill has housing divided in horizontal plane into two parts. Seed hopper mounted on upper part of housing is divided by partition walls into five conical sections. Hopper side and partition walls are mounted above hollow seeding rotor provided with cells so that two cells of each circular row of cells are positioned under each conical section. Tree rows of cells of different sizes are arranged under each outer conical section, two rows of similar cells are arranged under each of three mid sections and remaining cells are covered with inclined conical section walls. Outer row cells are designed for all kinds of beet and pea, cells of second row - for different kinds of radish, and cells of third row - for carrot and seed onion. Cells of second and third rows are disposed in five conical sections. Cell covering devices for sowing of seeds on small area requiring small amounts of seeds are made in the form of insertable partition walls adapted for isolating each row of cells. Partition walls are engageable with slots in conical section walls. When sowing of seeds on large areas is performed, cell covering devices made in the form of semirigidly fixed plates are used. Horn with side wings positioned at its lower side is fixed by bar at the bottom of housing under each conical section. Drill is further provided with seed spreader, segment with movable carrier fixed on tie-rod projection, and two wheels with lugs. Frame and closure are mounted on hopper. Housing is made from plastic, sheet metal or wood; seeding rotor is made from plastic or metal. EFFECT: increased efficiency in seeding vegetable seeds, wider operational capabilities and simplified construction. 15 dwg
