Weed dynamics and production potential of soybean (Glycine max L. Merill) as influenced by land configuration and weed control

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 yield of soybean, efficiency of different weed management practices under varying land configuration 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 Diclosulum84%WDG @22-26g 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, regarding all land configurations, seed yield (kg ha-1), straw yield (kg ha-1), biological yield (kg ha-1), GMR, NMR and B:C ratio were observed significantly maximum with 4 row BBF (L2) and regarding weed management practices, maximum values of the above mentioned parameters were recorded with treatment weed control (W3). Among weed management practices, the treatment (W2) PoE Sodium aceflurofen 16.5% + Clodinofop propargyl 8% EC @80+165 a.i. g/ha was found efficient in controlling monocot and dicot weeds as well as productive and profitable, it was comparable with weed free.
