A field experiment was carried out during kharif 2015 with thirteen ratios of nitrogen and phosphorus fertilizers with constant potassium level (25 kg K₂O ha⁻¹) on soybean cultivar DSb 21 at MARS, UAS, Dharwad. The seed yield increased due to increasing N/P ratios up to 0.78. The treatment receiving N/P fertilizer ratio of 0.70 (basal application of 18 kg N, 46 kg P₂O₅, 25 kg K₂O ha⁻¹ + foliar application of nitrogen@7 kg N ha⁻¹ at initiation of flowering and foliar application of nitrogen@7 kg N ha⁻¹ at 15 days after first foliar spray) recorded significantly higher seed yield (3217 kg ha⁻¹), total number of pods plant⁻¹ (47.57), 100 seed weight (15.40 g) and seed weight plant⁻¹ (18.31 g). This treatment also recorded significantly higher leaf area plant⁻¹ (12.62 dm²), leaf area index (4.21) and total dry matter production (34.15 g)
