A scientist’s position within the ranking is determined exclusively by their D-index (Discipline H-index), a metric that uniquely and accurately reflects a researcher's impact within the examined discipline. The D-index calculates citations and publications relevant solely to Plant Science and Agronomy, enabling a discipline-specific evaluation rather than a generic measure of scholarly output.
Scope of Research and Inclusion Criteria
The ranking examined a vast dataset of 279,971 scientist profiles drawn from a broad spectrum of bibliometric data sources spanning all academic disciplines. Within this comprehensive analysis, a focused subset comprising 204 scientists specialized in Plant Science and Agronomy was meticulously identified and evaluated.
To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 30, with a majority of their tier publications clearly concentrated in Plant Science and Agronomy. Additionally, significant recognition through awards and achievements in the field were factored into the evaluation process, ensuring that both quantitative metrics and professional distinction informed the ranking.
The threshold for D-index consideration is calibrated in increments of 10 relative to the total estimated number of scholars per discipline. This adaptive threshold ensures inclusion of approximately the top 1% of leading experts within each domain. Furthermore, a stringent criterion requiring a proximity of 30% or less between a researcher’s overall general H-index and their D-index was enforced to validate the disciplinary relevance of their scholarly record.
Verification Procedures and Methodological Rigor
Understanding the inherent limitations of raw bibliometric data, the Research.com team undertook rigorous manual verification of all scientist profiles. Each profile was carefully cross-correlated against publications documented in a wide range of authoritative sources to confirm accuracy and authenticity. This meticulous process safeguards the integrity of the ranking and ensures that it reflects true scholarly contributions.
Although the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, these outputs represent a valuable secondary indicator of a scientist’s contribution to the advancement of Plant Science and Agronomy.
The final positioning in the ranking is exclusively determined by each scientist’s D-index, computed based on curated information derived from OpenAlex and CrossRef—two of the most trusted and widely consulted bibliometric databases available to the global research community.
