    Performance of Soybean (Glycine max L. Merrill) Genotypes to Planting Geometry
    (University of Agricultural Science, Dharwad, 2016-06) Angadi, Lingaraj; Matiwade, P.S.
    ABSTRACT A field experiment was conducted during kharif 2015 to study “Performance of soybean (Glycine max L. Merrill) genotypes to planting geometry” at Agricultural Research Station (ARS), Nipani under rainfed condition. The experiment was laid out Randomized Complete Block Design with factorial concept and with four replications. There were 12 treatment combinations consisted of two varities ( JS-9305 and Dsb-21) and six row spacings (90 × 5 cm, 60 × 7.5 cm, 30 × 15 cm, 22.5 × 20 cm, 45 × 10 cm and 30 × 10 cm ). Soybean variety Dsb-21 produced significantly higher number of pods plant-1 (49.18), seed weight plant-1 (19.45 g), seed yield (22.20 q ha-1) and haulm yield (24.46 q ha-1) compared to JS-9305 variety. Among the different row spacings sowing of soybean at 45 x 10 cm recorded significantly higher number of pods plant-1 (53.70), seed weight plant-1 (21.31 g), seed yield (24.37 q ha-1) and haulm yield (26.49 q ha-1) compared to other treatments. In interaction effects significantly higher number of pods plant-1 (56.95), seed weight plant-1 (23.48 g ), seed yield (26.98 q ha-1) and haulm yield (29.10 q ha-1) were recorded in Dsb-21 when sown at 45 x 10 cm row spacing compared to other treatment combinations. Significantly higher gross returns ( 1,07,407 ha-1), net returns ( 78,252 ha-1) and B:C ratio (3.68) obtained in Dsb-21 when sown at 45 x10 cm row spacing compared to other treatment combinations. Sowing of Dsb-21 variety at 45 x 10 cm row spacing is optimum for getting higher soybean seed yield and net returns.
