A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that measures scholarly impact exclusively within the examined discipline. The D-index considers only papers and citations relevant to Plant Science and Agronomy, thus offering a precise reflection of a researcher’s contributions in the targeted field.
Scope and Criteria of the Ranking
This ranking encompasses an extensive evaluation of 279,971 scientist profiles drawn from diverse bibliometric databases spanning all scientific disciplines. Specifically, the ranking focuses on 3 scientists working within the field of Plant Science and Agronomy.
To qualify for inclusion in the ranking, a scientist’s D-index must be at least 30. Additionally, a majority of their publications must be classified as tier-level works within Plant Science and Agronomy to ensure discipline-specific excellence. Awards and achievements relevant to the field were also incorporated as ancillary factors reinforcing the standing of each scientist.
The threshold for the D-index is calibrated as increments of 10 relative to the estimated number of researchers in each discipline. This methodology ensures that approximately the top 1% of leading scholars by impact are incorporated into the list. Furthermore, to maintain disciplinary consistency, there is a criterion that the proximity between a scientist’s overall H-index and their D-index should not exceed 30%.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot provide an absolute evaluation of scientific performance, the research team conducted rigorous manual verification of all scientist profiles included in the ranking. Each profile was cross-correlated against publications indexed in a wide range of trustworthy sources to ensure accuracy and authenticity.
While not directly influencing the ranking position, the volume of papers published in prominent journals and conference proceedings serves as a valuable secondary signal, reflecting a scientist’s research contribution and visibility within Plant Science and Agronomy.
The final ranking positions are determined solely by the D-index derived from data aggregated from OpenAlex and CrossRef, given their comprehensive coverage and reliability. For an in-depth explanation of the methodology employed, we encourage readers to visit our methodology page.
