Yield Loss in No-till Corn Due to Weed Interference and Environmental Impact

Abstract

Field experiments over 4 years (1991-1994) were conducted at Taiwan Agricultural Research Institute Experimental Farm to evaluate the effects of weed interference and environmental impact on yield loss of corn (Zea mays L. cv. Tainung No.1) under no-till condition.本項研究係於1991-1994年在臺灣省農業試驗所農場進行田間試驗，以探討雜草干擾及環境效應對不整地栽培玉米減產之影響。參試品種為飼料玉米臺農一號(Zea mays L. cv. Tainung No.1)，雜草族群為田間自然生長之不同種類者，除草措施則為人工除草。雜草干擾處理計有八種，分別為雜草干擾0（全期無草），1，2，4，6，8，及10週與全期雜草干擾等。
