A scientist’s position within the ranking is determined using the Discipline H-index, also referred to as the D-index. This metric uniquely focuses on the scope of a researcher’s output and citations strictly within the examined discipline—Plant Science and Agronomy in this case—thereby providing a more accurate reflection of a scholar’s impact specific to their field rather than their overall academic output.
Scope of Research and Qualification Criteria
The ranking process involved a thorough examination of 279,971 scientist profiles collected from a variety of bibliometric data sources, spanning all disciplines. From this extensive dataset, 19 scientists specializing specifically in Plant Science and Agronomy were identified and considered for inclusion. To qualify for the ranking, each scientist was required to have a D-index of at least 30, complemented by a majority of their tier publications falling squarely within Plant Science and Agronomy.
In addition to bibliometric measures, accolades, awards, and key achievements within the field were carefully evaluated as supplementary factors to affirm a researcher’s distinguished contribution. The threshold for the D-index is dynamically set in increments of 10, calibrated to the estimated total scholar population in each discipline. This approach ensures the inclusion of the top 1% of leading scientists within their respective fields. Moreover, a proximity criterion was applied whereby the discrepancy between a scientist’s overall H-index and their discipline-specific D-index remains within 30%, further validating the discipline-focused impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully encapsulate the quality and significance of scholarly output, the Research.com team carried out an extensive manual verification of all scientist profiles incorporated in this ranking. Each profile was cross-validated against publications listed in a broad array of reputable scientific outlets and indexing services, providing a rigorous quality control layer.
While the number of papers published in prominent journals and conference proceedings does not influence the ranking position directly, it serves as an important secondary indicator of a scholar’s active engagement and contribution to the field of Plant Science and Agronomy.
The ranking positions are ultimately established through the D-index calculated from data sources OpenAlex and CrossRef, recognized as the most authoritative and widely utilized bibliometric databases accessible to the research community today.
