Bibliometric data for this edition were collected on January 12, 2026. The ranking position of each scientist in the list is determined by their D-index (Discipline H-index), a citation-based metric that specifically reflects research impact within the examined discipline — in this case, Plant Science and Agronomy. By considering only papers and citations relevant to the discipline, the D-index delivers a focused measure of scholarly influence in the specialized field.
Scope of Research and Eligibility Criteria
This ranking was developed through a detailed review of 279,971 scientist profiles drawn from a wide array of bibliometric sources across all disciplines. Among these, 134 scientists focusing on Plant Science and Agronomy were further examined for inclusion in this specialized ranking.
To qualify for inclusion, a scientist’s D-index was required to be at least 30, ensuring that only researchers with substantial and significant contributions to the field were considered. Additionally, a majority of the candidate’s tier publications needed to fall squarely within Plant Science and Agronomy. A scientist’s awards and achievements related to the discipline were also carefully evaluated as part of the selection criteria.
The D-index threshold for top researchers is calibrated as an increment of 10 relative to the total estimated number of scholars within each discipline. This adaptive thresholding guarantees representation of the top 1% of leading scholars, tailored to disciplinary size and activity. Furthermore, a proximity criterion was enforced whereby the difference between a scientist’s general H-index and their D-index does not exceed 30%, ensuring the discipline-specific impact is a substantial portion of their overall research influence.
Verification and Validation Processes
The Research.com team acknowledges that raw bibliometric data alone cannot fully capture the nuanced contributions of scholars. Consequently, all scientist profiles included in the ranking were subject to rigorous manual verification and cross-correlation against their publication records across a range of trustworthy academic sources.
While the final ranking is based exclusively on the D-index calculated from OpenAlex and CrossRef data, the number of papers published in prominent journals and conference proceedings was considered an important secondary indicator of a scientist’s influence and active participation in the niche community.
This meticulous validation procedure ensures credibility and robustness in the ranking outcomes. Readers seeking further technical detail about the methodology are encouraged to consult our methodology page.
