A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that focuses exclusively on publications and citations within the examined discipline of Plant Science and Agronomy. This discipline-specific approach ensures that the ranking fairly reflects expertise and contribution within the relevant scientific area, rather than general scholarly output.
Scope of Research and Ranking Criteria
The ranking evaluation encompassed an extensive pool of 279,971 scientist profiles aggregated from a variety of bibliometric data sources across all scientific disciplines. Within this large dataset, the focus narrowed to identify and assess 5 prominent scientists specifically within the field of Plant Science and Agronomy.
To qualify for inclusion in the ranking, a researcher was required to satisfy a minimum D-index threshold of 30, ensuring that only scholars with a significant and demonstrable impact in Plant Science and Agronomy were considered. Furthermore, the majority of a qualifying scientist’s tier publications needed to be concentrated within this discipline. Additional consideration was given to each candidate’s awards, honors, and recognized achievements in Plant Science and Agronomy, further validating their standing in the field.
The D-index cutoff values are adaptively set in increments of 10, calibrated according to the estimated size of the scholar population in each discipline. This dynamic thresholding guarantees inclusion of the top 1% of leading experts per field while maintaining a high standard for excellence. A further criterion requires that a scientist’s general H-index and their discipline-specific D-index exhibit a proximity of 30% or less, safeguarding the discipline relevance of the ranking.
Additional Verification Practices
At Research.com, we acknowledge the inherent limitations of raw bibliometric data as a sole evaluative tool for scholarly productivity and impact. To address these concerns, all scientist profiles included in the ranking underwent rigorous manual verification. This process involved cross-checking each profile against publications listed in a diverse range of trusted academic sources and databases, ensuring accuracy and reducing potential discrepancies.
Although the number of papers published in prestigious journals and conference proceedings is not a direct factor influencing the position in the ranking, it serves as an important secondary signal of a researcher’s contribution to the advancement of Plant Science and Agronomy.
The final ranking is based on each scientist’s D-index, derived from the carefully curated data from OpenAlex and CrossRef. These platforms represent the most prominent and well-established bibliometric databases currently accessible to the research community.
