| Abstract | Organic farming systems are based on principles of nutrient cycling and the minimal use of external inputs. In India, Panchagavya, vermicompost, and farmyard manure are integral components of nutrient management in organic farming systems. The aim of this study was to characterize these three different organic preparations with respect to microbiological quality and impacts on early crop growth. Among the three preparations, Panchagavya had the highest population of total bacteria (22 × 10$^{9}$ cfu ml$^{−1}$), actinomycetes (60 × 10$^{4}$ cfu ml$^{−1}$), phosphate solubilizers (103 × 10$^{6}$ cfu ml$^{−1}$), fluorescent pseudomonads (151 × 10$^{5}$ cfu ml$^{−1}$), and nitrifiers (5.4 × 10$^{6}$ cfu ml$^{−1}$). Dehydrogenase activity (6.61 μg g$^{−1}$ h$^{−1}$) and microbial biomass carbon (89.6 μg g$^{−1}$) were also found to be higher in Panchagavya. The short-term plant growth test with Cajanus cajan seeds treated with Panchagavya showed enhanced length of root (19.4 cm) and shoot (16.9 cm), dry mass (147 mg), leaf area (14.57 cm$^{2}$), chlorophyll content (23 spad units), and photosynthetic activity (18.8 μmol m$^{−2}$ s$^{−1}$) after 15 days of sowing. Hence, these tests suggest that Panchagavya can be used as a low-cost preparation to support plant growth in organic agriculture. |

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.
