A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that exclusively considers papers and citation metrics within the examined discipline—Plant Science and Agronomy in this context. This approach enables precise evaluation of scientific impact tailored to discipline-specific research outputs.
Scope and Selection Criteria
In constructing this ranking, a thorough examination was conducted utilizing 279,971 scientist profiles identified from a plethora of bibliometric data sources across all scientific disciplines. From within this expansive dataset, 6,494 scientists specifically associated with Plant Science and Agronomy were studied in detail.
To qualify for inclusion in the ranking, a candidate’s D-index had to be at least 30, ensuring a focus on well-established researchers. Additionally, a majority of their tier publications were required to fall within the realm of Plant Science and Agronomy, affirming their core expertise in the discipline. Alongside bibliometric indicators, scientists’ awards and distinguished achievements in Plant Science and Agronomy were also considered to provide a fuller picture of their professional standing.
The D-index threshold for considering top researchers is calibrated in increments of 10, relative to the estimated total number of scholars in each discipline. This methodology guarantees that the top 1% of leading scholars are systematically incorporated into the ranking. Furthermore, a proximity constraint is enforced whereby the difference between a scientist’s general H-index and their discipline-specific D-index does not exceed 30%, maintaining consistency between general and discipline-focused research impact.
Verification Practices and Data Integrity
At Research.com, we recognize that raw bibliometric data alone are insufficient to fully evaluate the complex scientific contributions of scholars. Consequently, all scientist profiles underwent manual verification and were cross-correlated against publications from a wide array of trustworthy sources. This rigorous process enhances the credibility and accuracy of our ranking.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is recognized as a valuable secondary signal reflecting a scientist’s contribution to specific scientific domains.
The final ranking positions are established using each researcher’s D-index, synthesized from data primarily gathered from OpenAlex and CrossRef—two of the most prominent and trusted bibliometric databases available to the global research community.
