An experiment on weed dynamics and production potential of soybean as influenced by land configuration and weed control was carried out during the kharif season of 2022-23 at Research Farm of Agronomy Department, College of Agriculture, VNMKV, Parbhani with an objective to study the effect of land configuration and weed management on growth, yield of soybean as well as on weed flora and crop weed competition in soybean. The experiment was laid out in split plot design with three replications. The treatments were consisting of three land configurations as main plot treatments, L₁: 2 Row BBF, L₂: 4 Row BBF, L₃: Flat bed and four weed management practices as sub plot treatments, W₁: PE Diclosulum 84% WDG @ 22-26 g a.i./ha, W₂: PoE Sodium acifluorfen 16.5% + Clodinofop-propargyl 8% EC @ 80 + 165 a.i. g/ha, W₃: Weed control, W₄: Weedy check. On the basis of present studies, results revealed that, among weed management practices, at 20 DAS, the PE Diclosulum 84% WDG @ 22-26 a.i.g/ha (W₁) whereas, at 40 DAS, treatment PoE Sodium aceflurofen16.5% + Clodinofop propargyl 8% EC @ 80 + 165 a.i.g/ha (W₂) was found efficient in controlling monocot and dicot weeds and was comparable with weed free. Regarding all land configurations, plant height, number of branches plant^-1, number of functional leaves plant^-1, leaf area plant^-1, dry matter plant^-1 were observed significantly maximum with 2 row BBF (L₁) and regarding weed management practices, the maximum values of the above mentioned parameters recorded with treatment weed control (W₃). Additionally, seed yield (kg ha^-1) was observed significantly maximum with 4 row BBF (L₂) and regarding weed management practices, maximum seed yield kg ha^-1 was recorded with treatment weed control (W₃).
