초록
The study was conducted to evaluate effects of weed managements after false seedbed on the weed control and growth of spring and fall cabbages (Brassica oleracea L.) in an organic upland in 2013. Weed managements included rake, flame, PE mulch, and none treatment. The weed occurrence was not effectively controlled by rake treatment but controlled by flame treatment in spring and fall cultivation. PE mulch plots had 30% of tip-burn in spring cultivation. Weed managements after false seedbed were similar fresh weight, leaf number, and cabbage yield to the conventional PE mulch. Head of cabbage was the lowest on the none treatment. Fall cultivation reduced the weed density and increased yield of cabbage compared to those of spring in all treatment plots. In conclusion, rake or flame treatment after false seedbed markedly decreased weed occurrence, which was expected to use for management of environmentally-friendly vegetation as a substitute of PE mulch.
