- Field experiment was conducted to investigate the effects of Biozyme ᵀᴹ on soybean. Application of Biozyme granule and crop-plus spray with half of recommended nitrogen, phosphorus, and potassium (NPK) showed significant effects on all the growth and yield parameters of soybean. The greatest value for the number of trifoliate leaves (29.95 leaves plant ⁻¹), leaf area (1818.21 cm2 plant ⁻¹), leaf area index (5.946), total chlorophyll content (1.995 mg g ⁻¹ leaf fresh mass), number of nodules (35.086 plants ⁻¹), fresh and dry weight of nodules (0.664 and 0.1592 g plants ⁻¹), dry weight of root (8.564 g plants ⁻¹), pods plant ⁻¹ (69.0), seeds pods ⁻¹ (3.25), straw yield (3.122 t ha ⁻¹), biological yield (6.349 t ha ⁻¹), and grain yield (3.277 t ha ⁻¹) was observed with Biozyme crop-plus spray at 500 mL ha ⁻¹ plus half of recommended NPK and were significantly greater than control values. Biozyme crop-plus spray at 500 mL ha ⁻¹ plus half of recommended NPK performed better compared to other treatments.
