A key metric underlying the ranking is the D-index (Discipline H-index), a refined measure that evaluates a researcher’s scholarly impact strictly within the domain of Plant Science and Agronomy. This metric includes only publications and citation counts that are relevant to the examined discipline, providing a focused and discipline-specific assessment of scientific influence.
Scope and Criteria of the Ranking
The ranking undertook an extensive analysis of 279,971 scientist profiles identified across a wide spectrum of bibliometric data and all scientific disciplines. Specifically, within Plant Science and Agronomy, the analysis focused on 1,000 scientists dedicated to this field. To qualify for inclusion in the ranking, a researcher was required to have a D-index of at least 30, emphasizing a substantial and consistent scholarly output in the discipline.
Moreover, the majority of a scientist’s tier publications were required to be concentrated within Plant Science and Agronomy, ensuring the ranking reflects disciplinary expertise. Consideration was also given to scholars’ awards and achievements relevant to the discipline, enriching the evaluative framework beyond bibliometrics alone.
The D-index threshold is dynamically set in increments of 10 based on the total estimated number of scholars within each discipline, guaranteeing the inclusion of the top 1% of leading experts in the field. Additionally, to maintain a close alignment between general and discipline-specific impact, a proximity criterion mandates that a scientist’s overall H-index and their D-index differ by no more than 30%.
Verification and Validation Procedures
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team implemented rigorous manual verification processes alongside automated data compilation. All scientist profiles were carefully reviewed and cross-checked against a wide array of reliable publication sources to validate accuracy and authenticity.
While the number of publications in prominent journals and conference proceedings does not directly influence ranking position, this metric serves as a valuable secondary signal of a scientist’s contribution to the field and is taken into account qualitatively during verification.
The final research ranking positions are firmly grounded in each researcher’s D-index derived from the expertly curated bibliometric data from OpenAlex and CrossRef databases.
