The main objective of this study is to use bio-inoculants in relative to specific legume plant diversity for, enhanced nodulation and plant growth. Method involves organically based selection of 36 rhizobial strains, of which 6 strains were isolated to assess the efficiency of relative host-specific inoculation on nodulation and development in legumes viz. Vigna radiata. All promising combinations of the preferred rhizobial strain inoculants were tested under sterile conditions for improving nodulation and to screen the best isolate to be evaluated for its enhanced characteristics through inoculation by field trial in various soils. It was observed that the strains from Bhadrachalam forest BD1 are highly host specific for Vigna radiata plants and when inoculated, improved nodulation and enhanced plant growth. Because of the novel characters in BD1, further studies were carried out and was identified as Rhizobium sp. BD1 (NCBI Accession no. MT577595). The percentage of nitrogen content in Vigna radiata ranged between 1.2% to 2.9%. This Rhizobium sp. BD1 was tested for the unraveling and amelioration of crop production in barren, polluted and agricultural soils which showed enhanced characteristics in Vigna radiata plants. This method may be employed across the globe of same climatic conditions for the retrieval of plants in soils that carry agriculture unsuccessfully.
