헤어리벳베치 잔류물의 제초효과와 작물안전성에 미치는 영향을 연구하기 위하여 헤어리벳치 잔류물을 온실, 비닐하우스 및 포장조건에서 복토처리하여 실험을 수행하였다. 온실조건에서 헤어리벳치와 토양(60:40) 혼합처리에서 90% 이상 방제효과를 나타냈으며 90:10 혼합비율에서는 100% 고사되었다. 제초효과는 일반적으로 화본과잡초에 비해 광엽잡초에서 높은 경향을 나타났다. 헤어리벳치 잔류물은 비닐하우스에서는 갈퀴덩굴, 명아주, 질경이와 소리쟁이에서 우수한 제초효과를 보였고, 포장조건에서는 갈퀴덩굴, 소리쟁이와 털비름에서 제초효과가 높았다. 헤어리벳치 혼합비물(60:40)을 0.5~0.75cm 깊이로 복토하였을 때 비닐하우스와 포장조건에서 약 80% 이상의 제초효과를 나타냈다. 헤어리벳치 잔류물은 상추를 제외한 옥수수, 콩, 무, 고추, 배추, 오이, 토마토, 들깨에서 모두 작물의 생장에 영향이 없었다.

This study was conducted to evaluate the growth inhibition of weeds and selectivity of crop species by hairy vetch residues. The growth of all the weed species was suppressed greater than 90% at the ratio 60 : 40 of hairy vetch residues and no weeds were emerged at 90 : 10 mixture in the greenhouse....
This study was conducted to evaluate the growth inhibition of weeds and selectivity of crop species by hairy vetch residues. The growth of all the weed species was suppressed greater than 90% at the ratio 60 : 40 of hairy vetch residues and no weeds were emerged at 90 : 10 mixture in the greenhouse. It was noticed that broadleaf weed species were more suppressed compared to grass weed species. Growth of weeds was significantly reduced and the inhibition percent was increased with increasing application depths of hairy vetch mixture both in vinylhouse and in field conditions. Among the different application depths of hairy vetch mixture, 0.75 cm depth of application tended to inhibit more, but statistically no significant difference was observed between 0.5 cm and 0.75 cm application depth. The growth of weed species such as Galium spurium, Chenopodium album, Plantago asiatica, and Rumex japonicus was greatly suppressed in the vinylhouse and the growth of G. spurium, R. japonicus and Amaranthus retroflexus was suppressed significantly in the field condition. The growth inhibition of all the above mentioned sensitive weed species was approximately 80% at the application depth of 0.5 cm. Crop growth was not hampered by using the residues of hairy vetch. This study demonstrated that rotation crop residues of hairy vetch contained high allelopathic potential to different weed species without hampering the growth of crop species.

제안 방법
Hairy vetch residues was mixed with soil as mixture ratio of 0/100, 20/80, 40/60, 60/40, 80/20 and 90/10 (hairy vetch residues/soil) by volume. The allelopathic potential of different ratio of hairy vetch residues against several weeds and crop species were evaluated.
Information regarding crop resides of hairy vetch used for the suppression of weed growth is very limited yet. This study intends to examine the growth inhibition of weeds and crop selectivity to hairy vetch residues applied in different conditions.

25 cm including one control in a upland cropping field. Eight different crop species (20 seeds of each) were grown. Weeds were allowed to grow from the field.
성능/효과
Generally it was noticed that broadleaf weeds were suppressed more than grasses. The most susceptible weed species were Rumex japonicus and Aeschynomene indica where weeds were suppressed completely at the lowest mixture ratio (20：80) of hairy vetch followed by the species Bidens bipinnata, Chenopodium album and Amaranthus retroflexus, respectively. The growth inhibition of all grass weed species was less at the lower ratio of hairy vetch compared to broadleaf species, i.
75 cm. The weed species Galium spurium, C. album, Plantago asiatica and R. japonicus were most sensitive to hairy vetch. The trend of suppressing broadleaf weed species was also higher than grasses in vinylhouse condition.
