An experiment was carried out under a rain shelter at agro technology park of Eastern University, Sri Lanka. The time duration was five weeks. The complete randomized design (CRD) was used for arrange four treatments with ten replicates. The treatments were, T1- Application of Jeewamirtha once a week, T2- Application of Panchagaveya once a week, T3- Application of Amuthakarisal once a week and T4- Application of inorganic fertilizer based on the Department of Agriculture recommendations. The measured parameters during the research were plant height, leaf area, shoot and root biomass, nodules number, number of effective nodules, and nodules weight of the plant. The significant differences were founded among the treatments on tested parameter. The study found that the application of Jeewamirtha was showed the highest parameters of growth a well as nodulation of Soybean than the other treatments. The application Panchagavya, Amuthakaraisal and also inorganic fertilizer were given approximately same measurements for growth parameters. The Jeewamirtha could be used as a nutrient source to get maximum production of Glycine max while reducing the environmental impacts by chemical fretiliers.
