Abstract

This experiment was conducted to determine the agronomic characteristics for selection of the excellent barnyard millet and the herbicidal response for their weediness prevention in paddy rice. IT170609, IT195422 and EV2012 have produced more dry matter compared to other barnyard millets tested. In varietal characteristics by heading date, IT170609 showed medium maturing type and IT195422 and EV201 had late maturing type. The germination rate of IT170609, IT195422 and EV2012 on temperature was higher than Echnochloa oryzicola of native species, and it was definitely distinctive at 20 and $25^{\circ}C$. In the herbicidal response for their weediness prevention in paddy rice, imazosulfuron+benzobicyclone+penoxsulam SC showed control effect the extend of over 90% to IT170609, IT195422 and EV2012. Cyhalofop-butyl EC, penoxsulam SC and metamifop EC were very effective by 6~7 leaf stage of barnyard millets tested.

본 시험은 몇몇 사료용 피들의 생육특성과 논에서 잡초화 방지를 위하여 국내 논에서 사용량이 많은 제초제들에 대한 반응을 조사하기 위하여 실시되었다. 겨울철 유리 온실 내의 대형 콘크리트 폿트에서 사료 가능성이 높은 피 8계통들의 생육을 조사한 결과 IT170609, IT196421 그리고 EV2012 계통들이 건물중 생산성이 상대적으로 높았다. 출수기에 따른 품종적 특성은 IT170609 계통은 중만생종, IT196421 및 EV2012 계통들은 만생종으로 나타났다. 선발된 사료용 피 3계통에 대한 발아율은 재래종인 강피 보다 높았고, 20 및 $25^{\circ}C$에서 뚜렷하였다. 논에서 사료용 피들의 잡초화 방지를 위한 제초제 시험에서 토양처리제인 imazosulfuron+benzobicyclone+penoxsulam 액상수화제는 사료용 피 3계통에 대하여 90% 이상의 효과를 보였다. 경엽처리 제초제들인 cyhalofop-butyl 유제, penoxsulam 액상수화제, metamifop 유제는 사료용 피 6~7엽기까지 매우 높은 효과를 보였다.
