Abstract
Field experiments were conducted in the fall crop of 1990 and the spring crop of 1991 to evaluate growth and yield of corn (Zea mays L. cv. Tainung No.1) in responses to paraquat and glyphosate, with or without shielding, applied at three different times in the vegetative stage. Although weed control was improved, herbicide applications at 2, 4 or 6 weeks after planting (WAP) slightly reduced corn growth and yield relative to those of handweeding treatments, but higher than the weedy check.本文旨在調查與比較殺草劑巴拉刈〔(paraquat),1,1'-dimethy-4,4'-bipyridinium dichloride〕；及嘉磷塞〔(glyphosate),N-(phosphonomethyl) glycine〕噴施期和噴施法對玉米臺農一號生長與產量之影響。田間試驗係在臺灣省農業試驗所農場，分別於1990年秋作及1991年春作進行。相對於同期人工除草處理者，在玉米播種後2，4及6週噴施巴拉刈（24%溶液，3公升／公頃）及嘉磷塞（41%溶液，5公升／公頃）雖然具有較佳除草效果，玉米生長與產量則受到抑制。
