Potential for Plant Growth Promotion in Groundnut (Arachis hypogaea L.) by Inoculation of Native Rhizobium Strains

Abstract: Totally, five different Rhizobium strains were isolated and identified from root nodules of Arachis hypogaea L. collected from five different fields of Perambalur District, Tamil Nadu, and India. Screening the effect of Rhizobium strains on groundnut under pot culture method. Experiments in pot culture yielded promising Rhizobium strains introduced groundnuts increasing the plant biomass, nodule number, and yield compared with control. Among the five strains, strain number 3 (RS3) was gave higher shoot length (31.3 cm) and root length (17.7 cm), number of nodules (40) and yield (90.5 g) on 90 days.
