A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a tailored metric that exclusively considers the researcher’s publications and citation records within the scope of Plant Science and Agronomy. This discipline-specific approach provides a more precise evaluation of influence and productivity in the examined field.
Scope of Research and Qualification Criteria
Our evaluation encompasses an extensive dataset, where 279,971 scientist profiles identified across various bibliometric databases were initially screened across all fields of study. Out of these, 6,494 scientists specializing in Plant Science and Agronomy were assessed in detail.
To qualify for inclusion in this ranking, a scientist’s D-index had to be at least 30, ensuring a high level of disciplinary impact. Furthermore, a majority of each qualifying scientist’s tier publications were required to be within the Plant Science and Agronomy discipline. Recognizing that bibliometrics alone do not fully capture scholarly influence, significant awards and achievements relevant to Plant Science and Agronomy were also taken into consideration.
The threshold for the D-index is calibrated in increments of 10 relative to the estimated total number of scholars per discipline, with this structure guaranteeing that the top 1% of leading experts are included in the ranking. Additionally, we verify that the variation between a scientist’s overall H-index and their D-index remains within 30%, ensuring that their disciplinary focus is coherent with their general research impact.
Verification and Validation Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly productivity, every scientist profile featured in the ranking has undergone thorough manual verification. Profiles were cross-correlated with published works from a wide array of trustworthy academic sources to ensure accuracy and authenticity.
While the volume of publications in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is considered a valuable secondary indicator of scholarly contribution within a specific scientific domain.
The ranking positions are ultimately based on each researcher’s D-index calculated from authoritative information extracted from OpenAlex and CrossRef—currently among the most recognized and comprehensive bibliometric databases available to the scientific community.
