All bibliometric data used to derive the citation-based metrics for this ranking were collected on January 12, 2026. These metrics provide the quantitative foundation for the ranking methodology. A scientist’s position in the ranking is determined by their Discipline H-index, or D-index, which is a specialized metric considering only publications and citations within the examined discipline of Plant Science and Agronomy. This approach ensures that the ranking reflects domain-specific research impact rather than a researcher’s overall output across all fields.
Scope of Research and Qualification Criteria
The scope of this ranking encompasses a robust examination of 279,971 scientist profiles identified from an extensive range of bibliometric databases covering all scientific disciplines. Within this larger pool, 45 scientists specializing in Plant Science and Agronomy were analyzed in detail.
To qualify for inclusion in the ranking, a researcher’s D-index had to meet a minimum threshold of 30. Moreover, a majority of their tier publications had to be directly associated with Plant Science and Agronomy, ensuring discipline-specific relevance. Beyond bibliometrics, consideration was also given to awards and notable achievements within the field, providing a qualitative complement to the quantitative metrics.
The D-index threshold for top researchers is dynamically set in increments of 10 based on the estimated total number of scholars in each discipline. This calibration guarantees that the top 1% of leading scholars are represented. Additionally, to ensure the D-index is a reliable indicator of discipline-focused impact, a proximity criterion was applied: the difference between a scientist’s overall H-index and their D-index must be 30% or less.
Verification Practices and Methodological Rigor
The team behind the ranking recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. Consequently, every scientist profile included in the ranking underwent manual verification. This process involved cross-correlating listed publications against a broad spectrum of trustworthy sources to confirm accuracy and authenticity.
Although not a direct factor influencing ranking positions, the volume of papers published in prominent journals and conference proceedings was reviewed as a valuable secondary signal of a scientist’s contribution to Plant Science and Agronomy.
The final position of each researcher in the ranking is established based on their D-index, calculated through the integrated data from OpenAlex and CrossRef. These databases represent the most authoritative and widely accessible bibliometric resources to the research community, lending credibility and validity to the ranking outcomes.
