A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that counts only those publications and citations strictly pertinent to the examined discipline—in this case, Plant Science and Agronomy. This approach provides a focused and discipline-specific measure of scholarly impact, offering a more precise reflection of expertise and contribution within the field.
Scope of Research and Qualification Criteria
The ranking process examined a total of 279,971 scientist profiles identified from a broad spectrum of bibliometric data sources across all scientific disciplines. Within the specialized realm of Plant Science and Agronomy, 27 scientists were specifically assessed. To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 30, reflecting a high level of research impact in the domain. Additionally, a majority of the researcher’s tier publications needed to be in the area of Plant Science and Agronomy, ensuring strong topical relevance.
Beyond bibliometric measures, scientists’ awards and recognized achievements within the field were also considered thoughtfully in the evaluation. The D-index threshold for classification of top researchers is strategically set at increments of 10, adjusted according to the total estimated number of scholars within each discipline. This methodology ensures that the top 1% of leading scholars are incorporated into the list, maintaining both rigor and exclusivity. To preserve disciplinary focus, there is a requirement that the divergence between a scientist’s general H-index and their D-index remains approximately 30% or less.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as absolute evaluative tools, the Research.com team implemented a meticulous manual verification process for all scientist profiles included in the ranking. Each profile was cross-correlated against publications registered in an array of trustworthy sources, enhancing the integrity and validity of the final list.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s position within the ranking, it serves as a valuable secondary indicator of their contribution to Plant Science and Agronomy research. The primary ranking metric remains the D-index, calculated using information exclusively gathered from OpenAlex and CrossRef, the two most prominent and widely respected bibliometric databases accessible to the scientific community today.
