Abstract
본 시험은 직파시기가 총체 벼의 수량 및 사료에 미치는 영향을 구명하기 위하여 2005년부 터 2006년까지 축산과학원 초지사료연구센터 시험포장에서 수행되었다. 총체 벼 품종은 남일벼로 하였고 4월 25일부터 6월 4일까지 15일 간격으로 직파하였고 5월 25일 이앙구를 대조구로 하였다. 출수기는 파종기가 늦어짐에 따라 지연되었으며 조단백질 함량은 증가되었다. ADF 및 NDF 함량은 파종이 늦어짐에 따라 증가되었으며 평균 TDN 함량은 61.5%이었고 파종이 늦어짐에 따라 감소되었다. 건물수량은 4월 25일 직파 및 5월 25일 이앙구에서 각각 15,185 및 15,815kg/ha로 가장 높았다. 이상의 결과를 종합하여 볼 때 직파시기가 늦어짐에 따라 수량적인 감소가 있지만 답리작 수확과 연계할 때 5월 중순경 직파를 하는 것이 연중 조사료 생산 측면에서 가장 우수하다고 판단된다. This experiment was conducted to evaluate the effect of direct seeding time on the yield and quality of whole crop rice at experimental field of Grassland and Forages Research Center, National Institute of Animal Science, RDA from 2005 to 2006. Whole crop rice variety, "Namil", was direct seeded at five different calender date (25 April, 10 May, 25 May, 4 June and transplanted at 25 May). The heading date was delayed at late seeding date. Crude protein (CP) was increased with delayed direct seeding date. The content of ADF (acid detergent fiber) and NDF(neutral detergent fiber) increased with delayed seeding date. The average TDN (total digestible nutrient) content was 61.5% and it also decreased with delayed direct seeding date. The highest DM (dry matter) yield was seeded at 25 April and transplanted at 25 May, 15,185 and 15,815 kg/ha, respectively. Although delayed direct seeding date decrease the DM yield, mid-May will be recommendable as proper direct seeding date.
