FIELD: agricultural engineering. SUBSTANCE: seeding unit has seeding disk, roller-baffle positioned inside casing, and ejectors provided with through openings arranged in circular path circumscribed from disk center. Ejectors are positioned for rotation about seeding disk axis. Such construction allows seeds of crops with different physico-mechanical properties to be ejected from outer disk cells arranged at an angle to disk axis and spread over furrow without usage of auxiliary appliances. Seeding disk may be used for precise drilling of tilled crop seeds. EFFECT: increased efficiency and simplified construction. 5 dwg
