A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that accounts solely for a researcher’s publications and citation impact within the specific discipline under examination — in this case, Plant Science and Agronomy. This approach guarantees that the ranking accurately reflects scientific influence within the relevant field rather than general citation counts.
Scope of Research and Inclusion Criteria
The ranking process entailed the examination of 279,971 scientist profiles extracted from a diverse array of bibliometric data sources across all scientific disciplines. Within this extensive corpus, specifically 1,115 scientists engaged in Plant Science and Agronomy were identified and analyzed in detail.
To qualify for inclusion in the ranking, each candidate’s D-index had to meet a minimum threshold of 30. Additionally, a majority of their tier publications were required to be evidently situated within the domain of Plant Science and Agronomy. Evaluation of a scientist’s awards and achievements relevant to the field was also incorporated as a qualitative dimension in the ranking methodology.
The D-index threshold is dynamically adjusted in increments of 10 based on the estimated total number of scholars in each discipline, ensuring the representation of approximately the top 1% of leading researchers. Furthermore, a criterion enforcing a maximum proximity of 30% between a scientist’s general H-index and their discipline-specific D-index was applied to ensure that the rankings reflect focused disciplinary expertise rather than generalized citation performance.
Verification and Validation Practices
Recognizing the limitations of raw bibliometric data as an absolute evaluative tool, the Research.com team has implemented rigorous manual verification protocols. Each scientist’s profile was carefully verified and cross-correlated against publications indexed in a broad spectrum of credible and trustworthy scholarly sources. This meticulous process safeguards the accuracy and reliability of the ranking, enhancing its credibility within the scientific community.
While publication volume in prominent journals and key conference proceedings is not directly factored into the final ranking position, such metrics serve as valuable secondary indicators of a scientist’s contribution and impact within Plant Science and Agronomy research.
The ranking is ultimately established using each researcher’s validated D-index, calculated from data curated by OpenAlex and CrossRef — two of the most prominent and well-respected bibliometric databases accessible to researchers worldwide.
