The bibliometric data underpinning the citation-based metrics used in the ranking were collected on January 12, 2026. A scientist’s position in this ranking is determined by their Discipline H-index, or D-index, a refined metric that considers only papers and citation counts strictly within the examined discipline—Plant Science and Agronomy—thus enabling discipline-specific impact assessment.
Scope of Research and Eligibility Criteria
The ranking process began with an extensive examination of 279,971 scientist profiles identified across a broad spectrum of bibliometric sources, spanning all disciplines. Of these, 7 scientists specializing in Plant Science and Agronomy in Slovakia were considered.
To qualify for inclusion, researchers were required to have a D-index of at least 30, ensuring a high standard of scholarly contribution. Additionally, a majority of their tier publications had to be focused on Plant Science and Agronomy. Awards and notable achievements within this field were also factored into the evaluation.
The D-index threshold is set as increments of 10, calibrated to the estimated number of scholars per discipline, guaranteeing the incorporation of the top 1% of leading researchers in each field. Furthermore, a proximity requirement ensures that the difference between a scientist’s general H-index and their D-index does not exceed 30%, maintaining consistency between overall productivity and the discipline-specific impact.
Verification and Validation Practices
Understanding that raw bibliometric data alone cannot fully capture the nuances of scholarly output, the ranking team performed meticulous manual verification of all scientist profiles. This process involved cross-correlating authorship and publication records against multiple trusted sources to validate accuracy and authenticity.
While not a direct factor influencing positional ranking, the number of papers published in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contribution to the Plant Science and Agronomy community.
Ultimately, the ranking positions are established based on each researcher’s D-index derived from data provided by OpenAlex and CrossRef, which remain the most prominent and widely respected bibliometric databases available to the global research community.
