Abstract: 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 was laid out in randomized block design with three replications. The soil was loamy in texture, low in available nitrogen (197.5 kg ha-1), medium in available phosphorous (18.4 kg ha-1) and very high in potassium (480 kg ha-1). The soil was moderately alkaline in reaction (pH 8.26). The experiment comprised of eight treatments T1- Preparation of ridges and furrows at 45 cm distance and sowing at one side(45cm x 10cm),T2- Preparation of ridges and furrows at 45cm distance and sowing at both side(22.5cm x 10cm),T3- Preparation of ridges and furrows at 60cm distance and sowing at one side(60cm x 10cm),T4- Preparation of ridges and furrows at 60cm distance and sowing at both side(30cm x 10cm),T5- Preparation of ridges and furrows at 90cm distance and sowing at both side (45cm x 10cm), T6- Preparation of BBF [90 cm top and 120cm base] and sowing at 22.5 cm distance (22.5cm x 10cm), T7- Preparation of BBF [90 cm top and 120 cm base]and sowing at 30 cm distance(30cm x10cm), T8- Flat bed (45cm x 10 cm).
The growth parameters viz plant height (75.57 cm) significantly recorded highest at harvest on 45 cm ridges and furrows sowing at both side (22.5cm x 10cm) with seed rate 67 kg ha-1. Number of compound leaves (29.80) at 90 DAS, number of branches plant-1 (6.27) at 90 DAS and dry matter plant-1 (40 g) at harvest and nodulation count at flowering stage (52.07) were significantly recorded 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.Significantly maximum uptake in N (120.79 kg ha-1), P (18.83 kg ha-1) and K (98.60 kg ha-1) by soybean was observed on preparation of ridges and furrows at 60cm distance and sowing at two sides (30cm x 10cm). Whereas minimum uptake in N (89.18 kg ha-1), P (14.40 kg ha-1) and K (75.39 kg ha-1) by soybean was observed on flat bed (45 cm x 10 cm).
