A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only those publications and citation counts pertinent to the examined discipline. This discipline-specific metric ensures the ranking accurately reflects expertise and impact within Plant Science and Agronomy, rather than the researcher’s general scientific contribution.
Scope of Research and Eligibility Criteria
To establish the ranking, a broad examination was conducted of 279,971 scientist profiles aggregated from a wide range of bibliometric data sources, spanning all scientific disciplines. Within this extensive dataset, two thousand scientists specializing in Plant Science and Agronomy were specifically assessed.
Eligibility for inclusion in the ranking required that a scientist meet two key criteria: first, a minimum D-index of 30, ensuring sufficient demonstrated research impact within the discipline; second, that the majority of their tier publications were centrally focused on Plant Science and Agronomy. Additionally, a researcher’s awards and professional achievements within the field were evaluated to augment the qualified selection process.
The D-index threshold is dynamically set in increments of 10, reflective of the estimated total number of scholars in each discipline. This methodology guarantees that approximately the top 1% of leading scholars are represented. Furthermore, to ensure consistency between a researcher’s general influence and their specialized impact, only those scientists whose general H-index differs from their D-index by 30% or less were considered.
Verification and Methodological Integrity
Recognizing that raw bibliometric data cannot serve as a definitive measure of scholarly output, the Research.com team undertook meticulous manual verification for all scientist profiles included in the ranking. Profiles were cross-correlated against publications and records in a diverse array of trustworthy and reputable sources to validate authenticity and accuracy.
While the quantity of publications in leading journals and flagship conference proceedings does not directly influence the ranking position, it provides an important secondary indication of a scientist’s substantive contribution to advancing research within Plant Science and Agronomy.
The ranking positions are established solely using the rigorously compiled D-index data, derived from OpenAlex and CrossRef — the foremost and most reliable bibliometric databases accessible to the global research community.
