Abstract: A field experiment was conducted during rainy season (khari.fJ of 2002 and 2003, to study the comparative performance of cultural, chemical and integrated methods of weed control in rainfed groundnut (Arachis hypogaea L.) n acid lateritic soils of West Bengal. Pre-emergence application of fluchloralin, pendimethalin, metolachlor and oxyfluorfen with or without hand weeding at 20 days after sowing (DAS) effectively controlled the weed population compared with the unweeded control. Among the weed management practices, pendimethalin @ 0.75 kg a.i./ha applied at pre-emergence coupled with one hand weeding at 20 DAS was found promising in reducing the weed density/ unit area and in enhancing the yield attributing characters and pod yield of groundnut in addition to benefiting monetary returns. This combination was comparable to that of hand weeding twice at 20 and 40 DAS which yielded the best result.
