A field experiment entitled “Standardization of optimum seed rate and yield maximization in soybean under different land configurations and sowing techniques” was undertaken during kharif, 2018 at Post Graduate Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). The experiment consists of eight treatments involving Preparation of ridges and furrows at 45cm distance and sowing at one side (45cm x 10cm), Preparation of ridges and furrows at 45cm distance and sowing at both side (22.5cm x 10cm), Preparation of ridges and furrows at 60cm distance and sowing at one side (60cm x 10cm), Preparation of ridges and furrows at 60cm distance and sowing at both side (30cm x 10cm), Preparation of ridges and furrows at 90cm distance and sowing at both side (45cm x 10cm), Preparation of BBF [90 cm top and 120cm base]  and  sowing at 22.5 cm distance (22.5cm x 10cm). Preparation of BBF [90 cm top and 120 cm base] and sowing at 30 cm distance(30cm x10cm), Flat bed (45cm x 10 cm). The experiment was laid out in randomized block design with three replications. The result revealed that the yield contributing characters recorded at harvest viz. number of pod
plant^-1 (56), pod weight plant^-1 (16.80 g). Weight of seeds pod^-1 (15.36 g), 100 grain (12 g) weight was obtained highest on 60 cm ridges and furrows sowing at one side (60 cm x 10cm) with seed rate 28.1 kg ha^-1. Significantly the highest grain yield (30.60 q ha^-1), straw yield (38.86 q ha^-1) were recorded  on 60 cm ridges and furrows sowing at two side (30 cm x 10cm) with seed rate 51.4 kg ha^-1.The quality parameter, protein content (40.23) was recorded highest on 60 cm ridges and furrows sowing at one side (60 cm x 10cm) with seed rate 28.1 kg ha^-1.The protein content was significantly influenced by different land configuration and sowing techniques and recorded highest on 60 cm ridges and furrows sowing at one side (60 cm x 10cm) with seed rate 28.1 kg ha^-1. The highest gross returns (Rs.117154 ha^-1) and net monetary returns (Rs. 65806 ha^-1) were recorded on 60 cm ridges and furrows sowing at two side (30 cm x 10cm) with seed rate 51.4 kg ha^-1. The similar trend was observed in case of benefit: cost ratio. The highest benefit: cost ratio (2.27) recorded with 60 cm ridges and furrows sowing at two side (30 cm x 10cm) with seed rate 51.4 kg ha^-1.
