Data Sources and Bibliometric Data Collection
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Greece Ranking is primarily based on data aggregated from leading bibliometric platforms, including OpenAlex and CrossRef, supplemented by a variety of additional reputable data sources. These sources provide comprehensive coverage of scholarly publications, citations, and related metadata. All bibliometric data employed to derive citation-based metrics for this ranking were collected as of January 12, 2026.
A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only publications and citations pertinent to the specific discipline under evaluation—in this case, Plant Science and Agronomy. This approach ensures the ranking reflects discipline-focused research impact rather than generalized scholarly productivity.
Scope of Research and Inclusion Criteria
The ranking process examined a total of 279,971 scientist profiles identified through multiple bibliometric databases, spanning all scientific disciplines. From this extensive dataset, 20 distinguished scientists with a focus on Plant Science and Agronomy were selected for inclusion.
To qualify for the ranking, a researcher was required to maintain a minimum D-index of 30, ensuring substantial scholarly contribution within Plant Science and Agronomy. Additionally, the majority of their tier publications had to be situated within this disciplinary area. Awards and notable achievements specific to Plant Science and Agronomy were also considered as supplementary factors reflecting a researcher’s influence.
The threshold for the D-index is adaptively set, increasing in increments of 10 depending on the estimated size of the researcher population within each discipline. This method guarantees that the top 1% of leading scholars in the field are reliably incorporated. Furthermore, a scientist’s general H-index and D-index must not differ by more than 30%, ensuring a close alignment of overall impact and discipline-specific impact.
Additional Verification Practices
The team behind this ranking recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or quality. Therefore, all scientist profiles underwent meticulous manual verification, including cross-correlation of publication records against a broad spectrum of trusted and authoritative sources.
While not factored directly into the positioning within the Research.com ranking, the volume of publications in top-tier journals and reputable conference proceedings is acknowledged as a valuable secondary indicator of a scientist’s contribution to their field.
The D-index utilized for rank determination is computed using data primarily from OpenAlex and CrossRef—arguably the most prominent and reliable bibliometric databases currently available to the global research community.
