| Abstract | In order to investigate the influence of exogenous application of calcium (Ca) on its accumulation in finger millet, two genotypes (GPHCPB-1 and GPHCPB-45), which posses low and high grain Ca contents, respectively, were subjected to regular fertigation of varying levels of Ca in Hoagland’s nutrient medium. The responsiveness of both the genotypes towards increasing exogenous application of Ca (0.1, 5.0, 10 and 20) was determined in terms of changes in tissue Ca levels, agro-morpho-physio-biochemical parameters. Sharp increase of Ca content in root, stem and spike was observed up to excess level of Ca (10 mM) in GPHCPB-1 while in case of GPHCPB-45 an increase in Ca content was observed only up to sufficient level of Ca (5 mM) and above that its accumulation remained constant or declined in both the genotypes. In case of leaf the level of Ca increased linearly at all concentrations of supplied Ca in both the genotypes. Both the genotypes behave differentially as GPHCPB-45 genotype accumulated more Ca and was also superior in root length, root dry matter accumulation, plant height and relative water content at Ca deficient condition (0.1 mM) as compared to GPHCPB-1 genotype. The continuous rise in stem diameter, biomass, seed yield, chlorophyll content, SPAD value, seed oxalic acid and phytic acid content were recorded in both the genotypes up to excess or toxic levels of supplied Ca. On the basis of present study it was concluded that Ca accumulation in plant is determined by both genetic (genotype dependent) as well as environmental factors (availability of Ca in rhizosphere). |

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.
