A field experiment was conducted during the kharif season of 2015 and 2016 to evaluate the effect of different land configurations and weed management practices on growth and yield of soybean at Instructional Farm, Krishi Vigyan Kendra, Aron, Guna (M.P.). The results revealed that the number and dry weight of weeds was significantly lower under S2, S3 and S4 land configurations as compared to the flat bed sowing (S1) at harvest stage. The total number of weeds/m2 ranged from 52.20 to 57.32/m2 under S2, S3 and S4 as against 76.54 weeds /m2 under S1 land configuration. Consequently, the dry weight of weeds was also recorded in the similar range according to their number/m2. The weed free (W6) performed the best where only 4.49 weeds/m2 were observed up to the harvest stage as against 194.82 weeds/m2 under unweeded control. Amongst the applied herbicides, Aceloflorfen + Clodinafop (W2) performed the best where 21.68 weeds/m2 were observed as against 194.82 weeds/m2 under control treatment. Among land configurations, raised bed furrow sowing gave significantly higher seed yield (13.04 q/ha) and maximum net income (Rs 24125/ha) with 1.93 B: C ratio. weed free condition recorded significantly higher seed yield (15.78 q/ha) as compared to the remaining treatments except Aceloflorfen + Clodinafop (W2) which produced 15.36 q/ha seed. Application of Aceloflorfen + Clodinafop (W2) resulted in highest net income up to Rs 34091/ha with B: C ratio 2.42.
