Abstract This study was conducted to determine the weed control effect of false seedbed in organic rice paddy field. False seedbed is one of the preventative weed control method, especially effective in upland vegetable field. False seedbed frequency and methods were examined by varying the processing time in greenhouse and field condition in 2012 and 2013. In greenhouse experiment, shallow recultivation and harrow surface soil was effective to control weed up to 70%. Optimal processing time of false seedbed was when the weed was two or three leaf stages. Under field condition, one-time treatment of false seedbed was 61% of weed suppression rate and two-times of false seedbed treatment was 79% of weed suppression rate. Monochoria vaginalis was still troublesome weed after false seedbed treatment, but the occurrence of Echinochloa oryzoides was decreased after false seedbed treament. Results indicated that false seedbed treatment was very effective to lower early weed occurrence in rice paddy field especially Echinochloa spp. Weed control efficiency of shallow recultivation by weeder hollow and rotary tillage by tractor were 68%, 13% respectively. 논에서 예방적 방제 방법인 가묘상의 적용 가능성을 검토하고자 가묘상의 횟수와 방법, 처리시기를 달리하여 온실과 포장에서 2012년과 2013년 2년 동안 본 연구를 수행하였다. 플라스틱 박스에 논흙을 담고 가묘상 방법과 처리 시기를 조사한 바 표토를 긁어주거나 얕게 뒤엎어주는 방법 모두 70% 이상의 잡초 억제 효과를 나타냈다. 또한 너무 잡초가 어린 1.5엽기 보다는 3엽기 일때가 효과적이여서 가묘상 처리는 잡초가 2-3엽기일 때 수행하는 것이 좋은 것으로 나타났다. 실제 포장조건에서의 가묘상 1회 처리 시 61%의 잡초가, 2회 처리 시 79%의 잡초 억제 효과가 나타났다. 가묘상 처리에 의해 전체적인 잡초의 발생량은 줄어들었으나 물달개비는 여전히 많이 발생 하였고, 강피는 가장 많이 줄어들었다. 이에 피속 잡초가 문제되는 논에서는 적극적으로 가묘상 방법을 활용하는 것이 초기 잡초밀도를 낮추는데 효율적인 것으로 판단되었다. 가묘상 처리 방법은 중경제초기로도 68%의 억제율을 보여 충분히 가능한 방법임을 입증하였으나 트랙터를 이용하여 로타리 경운을 하는 것은 상대적으로 낮은 효과를 나타냈다.
