Abstract:
A field experiment entitled “The effect of crop geometry and nutrient levels on growth and yield of soybean (Glycine max L.)” Was carried out during Kharif season of 2019 at Research Farm of Tirhut College of Agriculture, Dholi, RPCAU, Pusa, Bihar, India. The experiment was laid out in factorial randomized block design with three replications. Treatments comprised two parameters viz., crop geometry including 30 x10 cm, 45 x5 cm, 45 x 10 cm and 45 x 15 cm with fertilizer levels including 100% RDF, 120% RDF, and 140% RDF. The soil of the experimental plot was calcareous in nature having pH 8.32 and EC is 0.29dSm^-1. It was moderately fertile being medium in organic carbon (0.53%), available nitrogen (112.90 kg ha^-1), phosphorus (36.34 kg ha^-1), potassium (116.48 kg ha^-1) and sulphur (29.9 kg ha^-1).

The investigation revealed that crop geometry and nutrient level treatments significantly influenced growth parameters, yield attributes and yield of soybean, viz., Plant height (cm), Plant dry weight (g plant^-1), number of pods per plant, Number of seeds per pod, 100 seed weight (g), seed yield (q ha^-1), straw yield (q ha^-1)and harvest index (%).

Among the crop geometry treatments, (45 x 5 cm) recorded higher plant height, number of pod per plant, higher plant dry weight, maximum harvest index, number of seeds per pod with maximum seed yield (21.19 q ha^-1) and straw yield (26.30 q ha^-1) which was significantly superior over others while the lowest seed yield (17.84 q ha^-1) was obtained in the treatment of (45 x 15 cm), crop geometry (45 x 10 cm) registered maximum test weight. The highest Net returns (48911 ₹ ha^-1) was obtained in the treatment (45 x 5 cm) and lowest (39692₹ha^-1) in the treatment of (45 x 15 cm). The highest B: C ratio (1.41) was fetched in the treatment (45 x 5 cm) and (1.24) was in the treatment of (45 x 10 cm).

Among the nutrient level treatments, 140% RDF (NPK) recorded higher plant height, plant dry weight, number of pods per plant, number of seeds per pod, 100 seed weight (8.59 g), seed yield (20.02 q ha^-1), straw yield (25.45 q ha^-1), and highest harvest index (44.29%) was recorded in the treatment 120% RDF and this treatment was found to be significantly superior over others. The treatment 120% RDF has recorded highest number of nodules per plant (25.09).

The highest B: C ratio (1.38) was fetched in the treatment 120% RDF and lowest (1.25) in the treatment of (100% RDF).
