A key metric underlying the ranking is the D-index (Discipline H-index), which reflects a researcher's productivity and citation impact specifically within the discipline of Plant Science and Agronomy. This metric considers only those publications and citation counts relevant to the examined discipline, ensuring a focused and precise evaluation of scholarly contribution within the field.
Scope of Research and Inclusion Criteria
The ranking methodology involved an extensive examination of 279,971 scientist profiles drawn from a wide array of bibliometric data sources across all scientific disciplines. From this broad pool, 14 scientists specializing in Plant Science and Agronomy were identified and assessed.
To qualify for the ranking, a scientist’s D-index needed to be at least 30. Furthermore, a majority of their tier publications had to be concentrated in the discipline of Plant Science and Agronomy, thereby emphasizing domain-specific research excellence. The assessment also took into account scientists’ awards and notable achievements within the field, complementing bibliometric indicators with qualitative recognition.
The threshold for the D-index is adaptively set as increments of 10, based on the estimated population size of scholars in each discipline, while ensuring inclusion of the top 1% of leading researchers. Additionally, a proximity criterion requiring a difference of 30% or less between a scientist’s general H-index and their D-index was applied, promoting disciplinary alignment in the ranking.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot provide a fully comprehensive evaluation of scholarly impact, extensive manual verification was implemented. All scientist profiles were cross-checked and validated against publications indexed in a broad spectrum of trustworthy and authoritative sources. This rigorous approach safeguards the accuracy and integrity of the ranking results.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it remains a valuable secondary indicator of meaningful contributions to the field. The ranking position itself is ultimately determined by each researcher’s D-index, as derived from robust data aggregated through OpenAlex and CrossRef — the leading bibliometric databases widely utilized by the global research community.
