Abstract

본 시험은 논에서 벼 대체 여름 사료작물인 수수류를 논 재배하여 생육특성과 수량에서 우수한 품종을 선발할 목적으로 2008년부터 2009년까지 2년간에 걸쳐 충남 천안 농가 포장에서 수행하였다. 도입품종인 수수류 10품종 중에서 'Sordan79'는 습해에 비교적 강하고 2차 재생이 잘되며 당도가 높고 병해와 충해에 강한 생육특성을 보였고 수량 측면에서도 생초수량이 ha당 92,492 kg, 건물수량이 21,090 kg으로 가장 우수한 품종이었다. 따라서 본 연구결과를 토대로 볼 때 중부지역에서 벼 대체 사료작물인 수수류를 논에 재배 할때는 배수가 양호한 논의 선정이 필요하고 수수류 품종 중에서는 'Sordan79'를 재배하는 것이 적응성이나 생산성 측면에서 가장 유리하다고 할 수 있다. This experiment was carried out to know adaptability and forage production and quality of sorghum and sorghum <TEX>$\times$</TEX> sudangrass and sudangrass hybrids at paddy field from 2007 to 2008 at Chungnam province. Among growth characters, 'Sordan 79' hybrid was somewhat strong for waterlogging, and higher sugar content and good at the 2nd regrowth, disease and insect resistance. Fresh yield of 'Sordan 79' hybrid was the highest as 92,492 kg per ha among 10 Sorghum and Sorghum <TEX>$\times$</TEX> Sudangrass hybrids. The dry yield of 'Sordan 79' hybrid was also the highest as 21,090kg per ha. The result of this study showed that 'Sordan79' hybrid had good growth characters and forage productivity and crude protein (CP) and in vitro dry matter digestibility (IVDMD) at paddy field in middle region of South Korea.
