| Abstract | The work presents a comprehensive study on problems of supplementary photosynthesis in horticultural plants realised by artificial light sources of optimised wavelength spectrum. A purely photovoltaic method of powering these sources is provided in order to avoid mains energy consumption. Three goals of the project are specified i.e. scientific, applique and usable ones. The first one deals with elaborating of algorithms for controlling, measuring and supplementing the photosynthesis process. The second - with laboratory engineering and equipment, while the third goal deals with utilization of elaborated methods and means for improving the quality and harvesting of the irradiated plants. Apart from the natural sunlight portions the entire supplementary photosynthesis bases on sun energy PV conversion to the red and blue light energy, additionally emitted by groups of red and blue LEDs, each of 1 to 3 W power. Their light intensity and mutual light proportions are controlled and optimised by a computer programme and by the electronic PWM and MPPT technique. Such an irradiation process, if necessary, may be carried on also in night hours or in cloudy periods by means of PV energy stored in batteries |

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.
