Sesbania green manure after decomposition, increases humus, available nitrogen and lower down the C:N ratio of soil, aeration, permeability, enhance the boron and iron content in soil and also protect the soil from leaching of nutrients. Besides this significance, current study was carried out during rabi 2022 at ADAC&RI, Trichy to characterize the explored Daincha germplasms for their morpho biometric triats, green biomass yield and nodulation. Daincha germplasm Sivagangai local recorded more green biomass yield (19.8t / ha) and superior contributing biometrical traits. The number of Rhizobium colonies was Original Research Article
