| Abstract | Soybean is the most important of crop legumes with the highest share of production and source of biologically fixed nitrogen. Indigenous soybean rhizobia in Vertisols of Central India and other soils were assessed for cross nodulation, bacteriocin production and competitiveness. Survey of rhizobial populations in the rhizosphere of post-summer rainy season soybean revealed low number; the most probable number by plant infection test ranged from 0.5 to 3.3 × 10$^{3}$ cells g$^{−1}$ soil but improved in the rhizosphere of cool season chickpea as 3.6–9.6 × 10$^{3}$ cells g$^{−1}$. Soybean was nodulated by its native slow and fast growing rhizobia as well as by chickpea rhizobia. However soybean rhizobia did not nodulate crops belonging to four other cross inoculation groups-alfalfa (Trigonella), clover, pea, chickpea but nodulated Vigna (cowpea). Nodule occupancy by three indigenous nod$^{+}$ nif$^{+}$ Bradyrhizobium sp. R33 and R35 and Rhizobium R51 varied from 52 to 68 % of which only one-R33 was a strong bacteriocin producer while the other two were not. The results are important for rhizobial strain selection for biofertilizers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
