Abstract

This experiment was carried out to determine the harvesting day after heading of barley for highest total forage yield in double cropping with corn at paddy field in middle region. The fresh barley yield was the highest at the harvest of 20 days after heading, but the dry matter yield and TDN yield were the highest at the harvest of 25 days after heading because of higher dry matter rate. The dry matter yield of corn after the harvest of 25 days after heading was decreased about 16 percent than that of the check, sowing on april 25. But total fresh yield of corn monoculture was lower about 31 percent, and decreased 28 percent of dry matter and 23 percent of TDN yield, respectively, than that of the double cropping system with corn and barley. In double cropping system at paddy field, the total forage yield was the highest at the harvest of 25 days after heading of barley and grew corn subsequently. Although yield of corn was reduced by late sowing, the total forage yield was increased by double cropping system compared with corn monoculture.

논에서 청보리를 수확한 후 사료용 옥수수를 뒷그루로 재배할 경우 옥수수의 파종 시기는 청보리의 수확시기에 의하여 결정되고, 이에 따라 조사료 생산량이 영향을 받게 된다. 본 시험은 청보리를 생육단계별로 수확한 후 뒷그루로 사료용 옥수수를 파종하는 작부체계에서 조사료 생산성이 최대가 되는 청보리 수확시기와 사일리지 옥수수 파종시기를 구명코자 2009~2010년 충남농업기술원 논 시험포장에서 수행하였다. 청보리는 출수 후 20일에 수확하는 것이 생초수량이 가장 높았으나 건물수량과 TDN 수량은 황숙기에 수확(출수 후 25일경)하는 것이 가장 높았다. 옥수수는 청보리를 출수 25일에 수확한 후 파종하면 건물수량이 적기 파종에 비하여 약 16% 감소하였다. 옥수수 적기 파종에 의한 단작 재배는 청보리 출수 후 25일수확+ 옥수수 파종 작부조합에 비하여 총 생초수량 31%, 총 건물수량 28%, 총 TDN 수량 23% 감소되었다. "청보리+옥수수" 작부조합에서 총 생초수량은 '청보리 출수 후 15일 수확 ${\rightarrow}$ 옥수수 파종'이 가장 높았으나, 총 건물 수량과 TDN 수량은 "청보리 출수 후 25일 수확${\rightarrow}$사일리지 옥수수 파종"이 가장 높았으며, 이 때 청보리 생육단계는 황숙기이었고, 수분함량이 사일리지 제조에 가장 알맞은 시기이었다. 청보리를 황숙기 이후에 수확하면 옥수수의 수량이 급격히 감소되어 조사료의 총 생초수량과 TDN 수량이 크게 감소되므로 청보리를 황숙기 이전에 수확하고 옥수수를 가급적 빨리 파종할 필요가 있다.
