abstract
A field experiment was conducted at agriculture field of Himalayan University, Jollang during kharif season of 2023 and 2024 to study the response of composts and bio-fertilizers on growth and yield of black soybean [Glycine max (L.) Merr.]. The experiment was laid out in randomized block design with eight treatments and three replications. Results revealed that use of treatment T₄ (Vermicompost at 2.5 kg/ha + Phosphate solubilizing bacteria at 2.5 kg/ha) recorded significantly higher plant height (14.7 cm, 25.5cm, 35.3 cm) at 30 DAS,60 DAS, 90 DAS, leave length (5.73,7.7, 9.03) at 30 DAS, 60 DAS, 90 DAS, number of leaves of plant (17.3, 26.6, 38) at 30 DAS, 60 DAS, 90 DAS, However, lowest plant height (9.9 cm, 21.6 cm, 31.6 cm) at 30 DAS, 60 DAS, 90 DAS, lowest leave length (3.96, 4.8, 7.46) at 30 DAS, 60 DAS, 90 DAS, number of leaves (12, 22, 32) at 30 DAS, 60 DAS, 90 DAS was obtained in control treatment T₁. Dual inoculation of vermicompost and phosphate solubilizing bacteria improved the quality of soybean in presence of chemical fertilizers. The use of treatment T₅ (Vermicompost @ 5 kg/ha + Rhizobium @ 2.5 kg/ha) and treatment T₄ (Vermicompost at 2.5 kg/ha + Phosphate solubilizing bacteria at 2.5 kg/ha) gave at par results but statistically superior to control. Fresh weight at 30 DAS,60 DAS, 90 DAS (11.5 g, 20.1g, 27.1g) and dry weight at 30 DAS, 60 DAS, 90 DAS (10.3 g, 20.1 g, 30.2 g) were recorded highest with T₄ (Vermicompost at 2.5 kg/ha + Phosphate solubilizing bacteria at 2.5 kg/ha).
