Zusammenfassung:The object of this study was to determine the optimum seeding dates of “Donganbyeo”, “Daesan- byeo”, “Hoanbyeo”, “Nonghobyeo”, and “Gwanganbyeo” for direct seeding on dry paddy in Youngnam region. Dry seeds of these varieties were sown 5 times with 10-day intervals from April 20 to May 30. It took 12 to 14 days from sowing to emergence. It was shortened in the delayed seeding date, but the emerged seedlings per unit area was decreased as the seeding date was advanced before May. Heading date was delayed as seeding was delayed. Culm length, panicle length and number of spikelets per panicle was not affected by seeding date, but number of panicle per m² and ripened grain ratio were high from April 30 to May 10 seeding date. Consequently, the optimum seeding date for high yield of “Donganbyeo”, “Daesanbyeo”, “Hoanbyeo”, “Nonghobyeo”, and “Gwanganbyeo” was estimated May 3, May 2, May 10, May 8, and May 1, respectively.
