Research Productivity and Mapping on Neem: A Bibliometric Analytical Approach Indexed in Web of Sciences doi.org/10.26538/tjnpr/v6i1.20

Abstract

Azadirachta indica (Neem) A. Juss as an ethnobotanical has been used to treat various diseases due to its medicinal, insecticidal, and landscaping properties and has recently been used to synthesize other materials. The current study attempted to  aggregate research innovations on Neem through a bibliometric analysis for articles published between 1925 and 2020, using the Web of Science and a validated extensive literature search query that included keywords such as ―Neem‖, or ―Neem tree‖, or ―Azadirachta indica‖, or ―Melia azadirachta L‖, or ―Arya Veppu‖, or ―Azad Dirakht‖, or ―Nimba,‖ or ―Margosa.‖ The HistCite, Bibliometrix package in R and the VOS viewer software were used to generate the bibliometric indices and mapping. The search query returned 2347 documents, including 2298 articles and 49 reviews papers, with findings indicating that India was the most productive country in terms of article number, with 923 articles and 865 reviews respectively, while that Siddiqui BS from the University of Karachi was a top pioneer and active author. Furthermore, our findings demonstrated the utility of bibliometrics in addressing the key evaluation of Neem research, which will aid researchers in gaining a better understanding of future research direction, addressing key research evaluation questions and methods for providing additional insight, and evaluating hypotheses related to the structure and development of a field.
