Abstract
본 시험은 중부지역 답리작에서 파종시기를 달리하여 이탈리안 라이그라스(Italian ryegrass, IRG, Lolium multiflorum), 총체보리(barley, Hordeum vulgare), 호밀(rye, Secale cereale)을 재배할 경우 생육특성, 수량 및 사료가치에 미치는 영향을 구명하기 위하여 2004년부터 2005년까지 2년간 축산과학원(수원) 포장에서 시험을 실시하였다. 생육특성 및 숙기는 조기 파종(9월 26일)구에서 관행 파종(10월 11일)구보다 각 초종 공히 초장도 길고 $1m^2$당 유효경수도 많았다. 특히 호밀과 보리보다는 이탈리안 라이그라스의 경우 차이가 더 많아 조기파종 효과가 뚜렷하였다. 수확시기는 호밀과 코그린은 각각 개화기와 수전기로 적기였으나 보리는 호숙기, 화산 101호는 출수 시로 다소 조기에 수확되었으며 관행 파종 시는 이탈리안 라이그라스의 경우 더욱 늦어졌다. 따라서 이탈리안 라이그라스도 조생종인 코그린의 경우는 중부지역 벼 이앙에 지장이 없는 5월 20일 경 수확 적기에 도달할 수 있어서 앞으로 중부지방에서 답리작 재배의 가능성을 밝게 하고 있다. 수량은 조기파종(9월 26일) 구가 관행 파종(10월 11일)구보다 각 초종 공히 대폭 증수 되었으며 초종 간에는 호밀을 기준으로 하였을 때 총체보리는 18% 감소, 이탈리안 라이그라스는 $42{\sim}47%$가 감소되어 호밀이 가장 좋은 것으로 나타났다. 결과적으로 각 초종 공히 조기 파종 시에 증수되었으며 특히 숙기가 늦은 이탈리안 라이그라스와 보리에서 조기 파종의 효과가 뚜렷하였다. 사료가치는 조기 파종보다 관행 파종 시에 우수하였고 초종 간에는 생육시기가 늦은 화산 101호 > 코그린 > 보리 > 호밀 순이었다. 이와 같은 결과는 중부지역 벼 이앙시기인 5월 20일 경에 전 초종을 수확하게 되므로 숙기가 늦은 초종이 질적으로는 우수하였다는 것을 보여주고 있다. This study was conducted to determine the effects of seeding date on agronomic characteristics, productivity and feed value of Italian ryegrass, barley and rye during cropping after rice in Suwon, middle region of Korea, during 2004 and 2005. In general, early seeding (26 September) showed longer plant length and branch numbers per square meter than late sowing (11 October). Italian ryegrass had more early seeding effect than barley and rye. The yield of each plant was affected by sowing date in all experiments: the earlier seeding had higher yields than late seeding. In case of Italian ryegrass and barley as late-heading varieties showed more early seeding effect than rye. On the other hand, feed value tended to respond differently to yields. The feed value of each plant were based on liquid swine manure (12%) > composted cattle manure (7%) > composted swine manure (2%). The present results highlight the earlier planting obtained higher yield compared to those planted conventionally.
