This study was conducted to investigate the sowing time and sowing methods of the Rye(Secale cereale L.) for an organic soybean farming system. It can be seen that there was no significantly differences on soil chemical properties in the rhizosphere due to the Rye’s sowing season. A soil chemical properties due to the Rye’s sowing date in spring, O.M.(g ㎏⁻¹) contents was increased at a late Rye’s sowing dat, while on the other pH, Avail. P2O5(㎎ ㎏⁻¹) and CEC(c㏖+ ㎏⁻¹) were decreased. A highest yields of soybean was achieved at the plot which the Rye was sowed on 20th March with two-line, 5 row and 70㎝ row-space.
