| Abstract | Excessive dependence on chemical fertilizers, ignorance to organic and microbial inputs under intensive cropping systems are the basic components of contemporary agriculture which evolves several sustainability issues such as degraded soil health and sub-optimal crop productivity. This scenario urge for integrated nutrient management approaches such as microbes mediated integrated plant nutrition for curtailing the high doses as chemical fertilizers. Rationally, experiment has been conducted in pigeon pea at ICAR-IARI, New Delhi with the aim of identifying the appropriate nutrient management technique involving microbial and organic nutrient sources for improved rhizo-modulation, crop productivity and soil bio-fertility. The randomized block designed experiment consisted nine treatments viz. Control, Recommended dose of fertilizers (RDF), RDF+ Microbial inoculants (MI), Vermicompost (VC), Farm Yard Manure (FYM), Leaf Compost (LC), VC+MI, FYM+MI and LC+MI. Rhizobium spp., Pseudomonas spp., Bacillus spp. Frateuria aurantia were used as seed inoculating microbes. The results indicated the significant response of integration following the trend VC+MI> FYM+MI> LC +MI> RDF+ MI for various plant shoot-root growth attributes and soil microbial and enzymatic properties. FYM+MI significantly improved the water-stable aggregates (22%), mean weight diameter (1.13 mm) and geometric mean diameter (0.93 mm), soil organic carbon (SOC), SOC stock and SOC sequestration. The chemical properties viz. available N, P and K were significantly improved with VC+MI. Study summarizes that FYM+MI could result into better soil physico-chemical and biological properties and shoot-root development; however; VC+MI could improve available nutrients in the soil and may enhance the growth of pigeon pea more effectively. The outcomes of the study are postulated as a viable and alternative solution for excessive chemical fertilizer based nutrient management and would also promote the microbial consortia and organic manures based agro-industries. This would add into the goal of sustainable agricultural development by producing quality crop produce, maintaining agro-biodiversity and making the soils fertile and healthy that would be a ‘gift to the society’. |

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.
