A scientist’s position within the ranking is determined based on their Discipline H-index (D-index), a specialized metric that reflects research impact exclusively within the specific discipline under examination—in this case, Plant Science and Agronomy. The D-index thus ensures that only publications and citations directly relevant to the discipline contribute to a researcher’s ranking score, providing a precise measure of scholarly influence in the targeted field.
Scope of Research and Eligibility Criteria
The ranking examines a broad spectrum of researcher profiles to ensure an inclusive and representative overview of scientific leadership. From an initial pool of 279,971 scientist profiles identified across various bibliometric data sources spanning all disciplines, 53 scientists specializing in Plant Science and Agronomy were rigorously evaluated.
To qualify for inclusion in the ranking, a scientist must have attained a minimum D-index of 30, with a majority of their tier publications (high-impact works) falling within the Plant Science and Agronomy domain. Additionally, a researcher’s awards and recognized achievements specific to this field were considered to corroborate scientific excellence.
The D-index threshold for top researchers is dynamically adjusted in increments of 10, depending on the estimated total number of scholars within each discipline. This adaptive threshold ensures that the ranking consistently includes the top 1% of leading experts, thereby maintaining a selective and prestigious composition. Furthermore, to maintain focus on disciplinary impact, there is a requirement that the proximity between a scientist’s overall H-index and their D-index does not exceed 30%, reinforcing the disciplinary specificity of the metric.
Verification and Validation Practices
Recognizing the limits of raw bibliometric data as an absolute evaluative tool, the ranking process incorporates meticulous manual verification of all scientist profiles. This involves cross-correlating bibliometric records with publications listed in a diverse range of verified and trustworthy sources to ensure accuracy and validity.
Although not a direct factor in determining rank position, the quantity of papers published in prominent journals and reputable conference proceedings is regarded as a valuable secondary signal, highlighting a scientist’s substantive contributions within their scientific area.
The primary ranking metric—the D-index—relies on information aggregated from OpenAlex and CrossRef, the most prominent and widely recognized bibliometric databases accessible to the research community.
