Abstract
Abstract This study was carried out of investigate the effect of weed control methods on the growth of‘campbell early’ grape at the vineyards which was divided into the 18 zone (3.5 m × 5.5 m/zone) in the graperesearch institute. It’s investigated control effects, growth and quantity of grape and dominant weed ofJuly~August by sprayed glufosinate ammonium and paraquat dichloride each 3 times, fabric covering, grassplanting (Festuca myuros), mechanical weeding (3 times). The weed showed total of 16 species at thevineyards. Late-May to early growth stage of grape was dominated Chenopodium album and Trifoliumrepens , but to late growth stage of grape from mid-July was dominated Erigeron canadensis, Echinochloacrus-galli and Chenopodium album. Weed control effect of 10 day after treatment showed fabric covering100%, grass planting (Festuca myuros L.) 95.3%, mechanical weeding 81.9%, glufosinate ammonium (3times) 98.1% and paraquat dichloride (3 times) 90.4%, respectively. Growth of grape was higher herbicidestreatment and mechanical weeding than others. Yield tended to be higher glufosinate ammonium (3 times)and paraquat dichloride (3 times) each 12.6 kg/tree, 12.3 kg/tree than others.Key words Campbell early, Control effect, Grape, Growth, Weed
