Abstract: The field experiment comprising four Rhizobium inoculation treatments viz., no inoculation, inoculation with Rhizobium strains TAL-169, M-10 and AKR-1 respectively in main plots along with three nitrogen nutrition treatments viz., no N application, application of 20 kg N/ha at basal and top-dressing at 30 DAS, respectively in sub-plots, designed in split-plot, was conducted during 2017 and 2018 at the Instructional Farm, Jaguli of Bidhan Chandra Krishi Viswavidyalaya. Rhizobium inoculation and time of N application significantly influenced the number of nodules/plant, nodule dry weight/plant and leghaemoglobin content in greengram (cv. B-1). Among the different Rhizobium strains C₂, i.e., M-10 strain proved to be efficient in improving the nodule characters and ultimately seed yield of greengram. Inoculation with M-10 Rhizobium strain coupled with basal application of 20 kg N/ha increased seed yield of greengram to the extent of 56.6% as compared to no Rhizobium inoculation along with no N application. N, P and K uptake by the crop was improved when the seed was inoculated with M-10 strain. Rhizobium inoculation also improved the soil health by increasing the population of total bacteria and non-symbiotic N fixing bacteria in soil after harvest of the crop.
