PURPOSE: A seeder is provided to form a plurality of seeding grooves in a row when one proceeds while mounting seeds in the seeder and perform seeding as the seeds are fed and applied to the seeding grooves one by one by an air suction force. CONSTITUTION: A plurality of groove forming projections(7) are formed on the outer surface of a rotary drum(6) rotatably disposed in a lower front part of a main body(1) and a first shaft(1) is axially mounted thereon. The first shaft(9) penetrates through a guide hole(10) and receives an elastic force by a buffer spring(15) at a connector(11). A seed storage container(16) is disposed in an inner rear part of the main body(10) and a seed feed roller(17) provided in one side with an inner gear(18) is disposed in the seed storage container(16). A driving roller(19) provided at one side with an outer gear(20) engaged to the inner gear(18) is disposed by a second shaft(21). A second sprocket(22) is disposed in one side of the second shaft(21) to connect a chain(23) between a first sprocket(8) of the first shaft(9) and the second sprocket(22). A plurality of seed suction holes(24) are projected outward to some extent by a projecting section(25) on the outer circumference of the seed feed roller(17). A suction pump(26) is disposed inside the seed feed roller(17) and an air discharge pipe(28) is formed at a position contacting a seed guide plate(27).
