Bibliometric data used for calculating the citation-based metrics were collected on January 12, 2026, ensuring the ranking reflects the most up-to-date impact indicators available at the time. A scientist's position in the ranking is determined by their Discipline H-index, or D-index, a metric designed to capture research influence specifically within the discipline under examination. This ensures that only papers and citations relevant to Plant Science and Agronomy contribute to the assessment of each researcher’s standing in the ranking.
Scope of Research and Ranking Eligibility
The ranking process involved the examination of 279,971 scientist profiles identified across a broad range of bibliometric sources covering all academic disciplines. Within this dataset, 265 researchers specialized in Plant Science and Agronomy were evaluated in detail.
To qualify for inclusion, a scientist was required to have a D-index of at least 30, reflecting a substantial and focused impact within the Plant Science and Agronomy discipline. Additionally, a majority of each qualifying researcher’s tier publications had to be in this area, ensuring discipline-specific excellence. Researchers’ recognized awards and achievements within Plant Science and Agronomy were also carefully considered as supplementary factors to underscore outstanding contributions.
It is noteworthy that the D-index threshold is dynamically set in increments of 10 according to the estimated number of active scholars per discipline, while ensuring that the top 1% of leading researchers are encompassed in the ranking. Furthermore, only those researchers whose general H-index and D-index values differ by no more than 30% are included, thereby maintaining the integrity and relevance of the ranking to the discipline.
Verification and Methodological Rigor
The team behind this ranking is acutely aware that raw bibliometric data cannot serve as an absolute measure of scholarly impact. Consequently, all scientist profiles were subjected to manual verification and cross-referenced against publications tracked in a wide spectrum of trustworthy academic sources. This critical step guarantees the accuracy and reliability of the data underpinning the ranking.
Although not a direct factor influencing the position in the ranking, the quantity of papers published in prominent journals and conference proceedings is acknowledged as a meaningful secondary indicator of a researcher's contribution to the field.
The researcher’s ranking position is ultimately defined by the D-index calculated from data curated via OpenAlex and CrossRef, which are internationally recognized as leading bibliometric databases.
