Bibliometric Analysis in Scientific Articles on Nitrogen Fixation of Legumes

Abstract

Legumes has a great important in sustainable agriculture because roots are aerate and improve the physical, chemical and biological properties of soil. Legumes also enrich soil for nitrogen throughout symbiotic nitrogen fixation by rhizobia bacteria in nodules on roots and they provide products with low input. There are many studies about nitrogen fixation in legumes. However, indicating status and trends of researches are great important by bibliometric analysis. Bibliometric analysis is a useful method in literature review that reveals where research is done on a topic, models and mapping of research fields. In this study, 356 publications on nitrogen fixation of legumes between 1980-2023 were investigated using Web of Science (WoS) data and VOS viewer programme by bibliometric analysis methods. The highest number of publication on nitrogen fixation of legumes was produced in 1987, while the lowest one was in 1989. The most citation was achieved from year of 2021 with 1038 while the lowest was in 1980. Peoples, M., Sprent, J. and Urquiga, S. had highest number of publication. Plant and Soil has the most record count of publications. The organization with most publications was CSIRO. Swedish University of Agricultural Sciences had 438 citations with 6 documents while CSIRO had the 400 citations with 14 documents. USA and Australia had the highest numbers of publications. As a results, the study revealed fields of research, identify the main journal, authors, countries, research trends on nitrogen fixation of legumes by bibliometric analysis methods.
