PROBLEM TO BE SOLVED: To obtain seeds for direct seeding which enable mechanical seeding, allow the complete omission of raising seedling stage, etc., and improve seeding workability by evenly dispersing plural pieces of the seeds into a specific gelatinous material and molding the material to a spherical body of a prescribed range of the diameter. SOLUTION: Plural pieces of the seeds S, such as rice seeds, are evenly dispersed into the gelatinous material formed by compounding sodium alginate 1b with an agar soln. 1a and the material is molded to the spherical bodies of about 0.8 to 1.2cm in diameter. At the time of obtain the seeds for direct seeding, a flat plate sized approximately 30cm×30cm is preferably internally juxtaposed with many net-like hemispherical recessed cells of 1.0 to 1.5cm diameter.
