Field experiment conducted on black soils at the Main Research Station, University of Agricultural Sciences, Dharwad during Kharif 1996 to study the weed management in soybean (Glycine max (L.) Merrill) indicated that weedy check had the highest weed dry weight (20.95 kg/ha) with the lowest weed control efficiency and yield of soybean while, the highest weed control efficiency was observed with two intercuitivations + two hand weedings followed by alachior @2.0 Kg a.i./ha (86.45%). Weed free check recorded the highest seed yield (2220 Kg/ha) followed by two intercultivation + two hand weedings (2026 Kg/ha) consequent to the better yield attributes.
