Abstract

Optimum application level of liquid pig manure for increasing Astragalus sinicus L. (ASASI) and Lolium multiflorum Lam. (LOLMU) yield was investigated. The green manure crop yield were generally high in the order of ALPM 100 ${\geqq}$ APLM 75 ${\geqq}$ APLM 50 ${\geqq}$ APLM 0 in site 1 (ASASI), and LPLM 100 ${\geqq}$ LPLM 75 > LPLM 50 ${\geqq}$ LPLM 0 in site 2 (LOLMU). The optimum application level of liquid pig manure was 100% of nitrogen fertilization level.

녹비생산량 극대화를 위해 자운영과 라이그라스의 돈분액비 최적 투입량을 구명한 결과 녹비 생산량은 자운영 재배지 (site 1)의 경우 자운영 고사기에 시험되어 큰 차이는 없었으나 전반적으로 돈분액비 투입량이 많아짐에 따라 약간 증가되었으며, 라이그라스 재배지 (site 2)의 경우 LPLM 100 ${\geqq}$ LPLM 75 >> LPLM 50 ${\geqq}$ LPLM 0 처리구 순으로 돈분액비 투입량이 많아짐에 따라 급격히 증가하였다. 자운영과 라이그라스 재배지에서 녹비작물의 무기성분 함량은 자운영의 경우 ALPM 100 ${\geqq}$ APLM 75 ${\geqq}$ APLM 50 ${\geqq}$ APLM 0 순이었으며, 라이그라스의 경우 LPLM 100 ${\geqq}$ LPLM 75 > LPLM 50 ${\geqq}$ LPLM 0 순으로 두 재배지 모두 돈분액비 투입량이 많아짐에 따라 무기성분 흡수량이 증가하는 경향이었다. 따라서 자운영과 라이그라스 재배지에서 녹비생산량을 극대화하기 위한 최적 돈분액비 투입량은 질소 시비량 100%에 해당하는 조건이었다.
