legumes and rye on paddy field at the experimental field of Jeollanam-Do Agricultural Research and Extension Services from 2004 to 2008. The five treatments used in this experiment were rye mono (C.V. Koolgrazer), rye+chinese milk vetch mixture, rye+crimson clover (C.V. Linkarus) mixture, rye+forage pea (C.V. Austrian pea) mixture, rye+hairy vetch (C.V. Oregon Common) mixture. The dry matter (DM) percentage at harvest was 23. 0~25.3%. The DM percentage among rye single and mixture treatments were similar. The yields of fresh and crude protein (CP) were high in Italian ryegrass (IRG)+Forage pea mixtures as a 50,370 kg and 1,177 kg per ha. And the yields of dry matter were high in IRG+forage pea was at mixtures as a 12,390 kg/ha. The Av. P2O5 in IRG+forage pea mixture was 85 ㎎/㎏. In conclusion, the mixture cultivation of rye and forage pea was very effective
