A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that includes only those publications and citations relevant to the specific discipline under examination—namely, Plant Science and Agronomy. This approach ensures that the ranking reflects expertise and impact within the field rather than general scholarly output.
Scope of Research and Inclusion Criteria
The ranking is derived from an extensive examination of 279,971 scientist profiles identified across all disciplines from a variety of bibliometric data sources. From this broad pool, 20 scientists specializing specifically in Plant Science and Agronomy in Greece were evaluated.
To qualify for inclusion, a researcher’s D-index had to meet or exceed a threshold of 30, in addition to having a majority of their tier publications situated within Plant Science and Agronomy. Furthermore, demonstrated awards and achievements in the field were considered to enrich the evaluation.
The D-index threshold is dynamically set as increments of 10 relative to the estimated total number of scholars within each discipline, ensuring that the top 1% of leading experts are incorporated into the list. Additionally, a maximum proximity of 30% or less between a scientist’s general H-index and their D-index is maintained to verify that their scholarly impact is predominantly concentrated in the relevant discipline.
Verification and Secondary Considerations
The researchers behind this ranking are acutely aware that raw bibliometric data alone can never serve as an absolute tool for evaluating scholarly output. Accordingly, all scientist profiles underwent thorough manual verification and were cross-correlated against publications verified through a wide range of trustworthy sources.
While not directly influencing the rankings, the number of papers published in prominent journals and conference proceedings is regarded as a valuable secondary indicator of a researcher’s contribution and standing within Plant Science and Agronomy.
The ranking position is ultimately established through each researcher’s D-index, as calculated using the robust and authoritative datasets of OpenAlex and CrossRef. We encourage interested readers to consult our methodology page for a detailed exposition of the methodological framework and data handling practices employed throughout the ranking process.
