Abstract
Investigation on weed flora in Angelica gigas upland fields was conducted to understand the current status of the weed flora and establish the control measures. Investigation was conducted twice, July and October in 2015. From this investigation, 105 species of 37 families including 27 exotics were identified and classified into 53 species of annuals, 24 species of biennials and 28 species of perennials. Dominance was the highest with Digitaria ciliaris, followed by Portulaca loeracea, Chenopodium album, Cyperus iria, Conyza canadensis, Galinsoga ciliata etc. in order. Chenopodium album was the highest in importance analysis and the followings were in order of Conyza canadensis, Galinsoga ciliata, Amaranthus lividus, Taraxacum offcinale etc. The yield of A. gigas was reduced 49.6% in no weeding plots comparing in weed managed plots.
