Bibliometric data for devising the citation-based metrics used in this ranking were systematically collected on January 12, 2026. A scientist's position in the ranking is determined by a researcher's D-index (Discipline H-index), a specialized metric that considers only papers and citation data strictly within the examined discipline of Plant Science and Agronomy. This discipline-specific focus ensures that rankings reflect true impact and expertise pertinent to the field.
Scope of Research and Qualification Criteria
The ranking's scope is grounded in a large-scale analysis of 279,971 scientist profiles, identified from a diverse array of bibliometric sources spanning all academic disciplines. Within this dataset, 1,000 scientists specializing in Plant Science and Agronomy were examined for this ranking.
To qualify for inclusion, a scientist’s D-index had to meet a minimum threshold of 30, with the majority of their tier publications centered specifically in Plant Science and Agronomy. Additionally, consideration was given to notable awards and achievements pertinent to the discipline, further reinforcing the focus on impactful contributions within the field.
The D-index threshold used to select top researchers is calibrated as an increment of 10, reflective of the total estimated number of scholars within each discipline, thereby guaranteeing that the top 1% of leading experts are captured. Furthermore, a proximity criterion is applied such that the difference between a scientist's overall H-index and their discipline-specific D-index is maintained at 30% or less, ensuring consistency and relevance of the disciplinary impact.
Verification Practices and Methodological Rigor
The Research.com team is acutely aware that raw bibliometric data alone cannot fully capture the multifaceted output of scholars. Therefore, all scientist profiles included in this ranking underwent a meticulous manual verification process. This involved cross-correlating profiles and publication records against a wide range of credible and authoritative sources, ensuring accuracy and reducing the risk of misattribution or error.
While not a factor influencing the ranking position, the number of papers published in prominent journals and leading conference proceedings serves as a valuable secondary signal reflecting a scientist's substantive contribution to the Plant Science and Agronomy research community.
Positions in the ranking are ultimately derived using each researcher’s D-index based on the comprehensive data gathered from OpenAlex and CrossRef, recognized as the most prominent and trusted bibliometric databases accessible to the global research community.
