Abstract : A field experiment was conducted during Kharif season at 2007 at Research-cum-Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh), India, .to study theEffect of crop geometry and herbicides on growth and productivity in  soybean(Glycine max L. Merrill). The experiment was laid out in Split plot Design (SPD) with two treatments main plot six treatments sub plots and three replication.  At harvest, not significant affect by plant spacing but significantly higher seed yield obtained with treatment Fluchoralin@ 100 g ha-1 (PE) + Hand weeding at 40 DAS (2354 kg ha-1), however, it was found comparable with the yield of Hand weeding twice at 20 and 40 DAS (2316 kg ha-1). Significantly lowest weed count and highest weed control efficiency also recorded with T6
