Weeding Effect of Using Soybean Cake and Cultivating Weeder Together in Rice Bran Farming

ABSTRACT This study was conducted to improve weeding effect by rice bran farming technique. In the weeding effect experiment by application timing control of rice bran and soybean cake, weeding efficacy was the highest at the treatment of conventional application of rice bran. The treatment of soybean cake with rice bran was unfavorable, but Echinochloa crus-galli occurred little at the treatment of soybean cake at 5 days after transplanting, so it is thought that further study about inhibitor of early E. crus-galli occurrence in soybean cake is necessary. Cultivating weeder was effective at the treatments of rice bran and soybean cake together, of which weed occurrence was more than conventional rice bran, and precise experiments about cultivating weeding time and method will be necessary.Key words: cultivating weeder; rice bran; soybean cake; weeding effect. 서 언 최근 친환경농업에 대한 관심이 높아짐에 따라 농업 환경에 대한 부하를 최소화하려는 노력이 점점 증가하고 있다. 우리나라는 2013년까지 2003년 대비 화학비료와 농약 사용량을 40% 줄인다는 계획 하에 종합병해충 관리시스템 도입과 화학비료 줄이기 및 친환경농업 확대 등 다양한 시책을 시행하고 있다(농촌진흥청 2004). 그 중에서 주목받고 있는 방법 중 하나가 쌀겨농법이다. 이것은 일본에서 유기농 쌀 생산 농가들에 의해서 시작된 농법으로, 유기농의 가장 큰 문제인 잡초제거를 이 농법으로 일정부분 해결할 수도 있다는 점에서 도입하는 농가가 증가하고 있다(농업과학기술원 2005).
