A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a refined variation of the classical H-index that isolates only those papers and citations within the specific discipline under examination, in this case, Plant Science and Agronomy. This ensures that the ranking reflects excellence and impact strictly within the relevant research area.
Scope of Research Considered
The ranking is based on the examination of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources spanning all academic disciplines. Specifically, within the domain of Plant Science and Agronomy, 1,000 scientists were assessed. To qualify for inclusion in this specialized ranking, a scientist was required to have a minimum D-index of 30, with a majority of their tier publications categorized within Plant Science and Agronomy.
Furthermore, the evaluation incorporated scientists’ awards and professional achievements in the field, recognizing that academic distinction extends beyond citation metrics alone.
The threshold for the D-index is strategically set in increments of 10 relative to the estimated total number of scholars per discipline. This dynamic approach is intended to consistently include the top 1% of leading experts within each field. Additionally, to ensure disciplinary focus, selected scientists exhibit a proximity of 30% or less between their general H-index and their D-index, underscoring their concentrated impact within Plant Science and Agronomy.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot provide a comprehensive or absolute measure of scholarly output, the Research.com team undertook meticulous manual verification of all scientist profiles. This process included cross-referencing publications against a wide array of trustworthy sources to confirm accuracy and authenticity.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s positioning in the ranking, it remains an important secondary indicator of their contribution and influence within the discipline.
The final ranking positions are established solely using each researcher’s D-index, derived from author data aggregated from OpenAlex and CrossRef. These databases are acknowledged as the most established and widely respected platforms in bibliometric research worldwide.
