Evaluation of Rhizobium along with Multifunctional Rhizobacteria for Improving the Growth and Yield of Black Gram [Vigna mungo (L.) Hepper]

Background: Indigenous rhizobial populations may be unable to achieve successful symbiosis in the field due rare population and unfavourable soil environment. Introduced plant growth promoting rhizobacteria (PGPR) are frequently linked faster growth, development, yield of with synergetic effect on indigenous Rhizobium bacteria. Furthermore, co-inoculating legumes both PGPR is proven more effective for improving nodulation as well development legumes. Methods: The experiment was conducted at research farm TCA, Dholi Muzaffarpur a campus Dr. Rajendra Prasad Central Agriculture University, Pusa, Bihar during kharif season 2021 investigate “Evaluation along multifunctional Rhizobacteria black gram [Vigna mungo (L.) Hepper]”. There were eight number treatments replicated thrice randomized block design. treatment comprised T1- control, T2- (Bradyrhizobium spp.), T3- + PUK-171 (Stenotrophomonas rhizophila), T4- NE 10 (Bacillus cereus), T5-Rhizobium Pseudomonas spp., T6-Rhizobium LMSR 45 (Pantoea agglomerans), T7-Rhizobium Methylobacterium, T8-N per RDF. Result: result revealed that co-inoculation rhizophila) significantly increase height, leaves plant-1, branches plant‑1, dry weight, crop rate, nodule studies nodules weight recoded higher compare T1, T2, T8 found par rest treatment. In attributing character pods plant-1 recorded did not produce significant effect, case seed similar trends followed, while stover cereus) T1 treatments. Harvest index effect.
