초록
This study was conducted to evaluate the effects of crop rotation on the weed occurrence in green onion and red pepper cultivation. Rye and hairy vetch were annually seeded for winter season. The reduction of weed germination was pronounced by about 50% in green onion field, but was not significant in red pepper field through rye cropping. Among weed species, the germination of Abutilon theophrasti, Cyperus iria and Digitaria ciliaris was distinctly inhibited by exudate of rye root, but not by that of hairy vetch in vitro experiment. The return of rye biomass into onion field decreased amount of weed biomass but increased index of weed diversity.
