Data Sources and Citation Metrics
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Canada Ranking is grounded in rigorous bibliometric data primarily derived from two cornerstone databases: OpenAlex and CrossRef. These platforms are complemented by multiple other reputable data sources, ensuring a robust and comprehensive dataset for analysis. Bibliometric data used to calculate the citation-based metrics comprising this ranking were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric metric that specifically includes papers and citation counts within the examined discipline, thereby providing a focused measure of impact in Plant Science and Agronomy.
Scope of Research and Ranking Criteria
Our analysis examined a total of 279,971 scientist profiles sourced from a broad spectrum of bibliometric databases covering all academic disciplines. Within this comprehensive set, 267 researchers specializing in Plant Science and Agronomy were identified and further evaluated. To qualify for inclusion in the ranking, scientists were required to have a D-index of at least 30, ensuring recognition of sustained scholarly impact within the discipline. Additionally, a majority of tier publications had to be within the field of Plant Science and Agronomy. Consideration was also given to scientists’ notable awards and achievements specific to this area.
The D-index threshold for selecting top researchers is systematically calibrated as an increment of 10, adjusted based on the estimated total number of active scholars in each discipline. This ensures inclusion of the top 1% of leading experts while maintaining disciplinary relevance. Furthermore, a proximity constraint is applied such that a scientist’s general H-index and their D-index differ by no more than 30%, reinforcing the specificity of their disciplinary impact.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture the nuanced contributions of scholars, the Research.com research team has undertaken meticulous manual verification of all scientist profiles. This process includes cross-correlation with publications found in a wide array of trustworthy academic sources, safeguarding against data anomalies or misattributions. While the number of papers published in prominent journals and conference proceedings does not directly factor into the rank position, it serves as a valuable secondary indicator of a scientist’s contribution and engagement within their field.
Positions in the ranking are ultimately established using each researcher’s D-index, as computed from data aggregated primarily through OpenAlex and CrossRef—currently the most prominent and widely recognized bibliometric databases accessible to the global research community.
