A search of the term biostimulants on the most renowned scientific online databases such as Web of Science results in more than one thousand documents. Although some reviews have been previously published, there is no unified and comprehensive bibliometric review of the scientific literature related to biostimulants. This study examines the scientific literature on biostimulants from 2000 to February 2022 by conducting a bibliometric analysis of the literature published on the Web of Science database to deepen its evolution, trends, and macroareas to represent a quick reference guide for interdisciplinary researchers. We identify the most productive countries and journals, detect the major research streams and perspectives, and trace overall research development over the years. Furthermore, the results highlight aspects that have had little consideration in the current scientific literature, such as economic assessments of the use of biostimulants and more comprehensive explanations of the molecular mechanisms responsible for their positive effects.
