A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively accounts for publication and citation metrics within the examined discipline of Plant Science and Agronomy. This approach enables a more focused assessment of a researcher’s impact specific to their area of expertise, minimizing distortions caused by interdisciplinary variations in citation behaviors.
Scope of Research and Qualification Criteria
The compilation of this ranking involved the examination of 279,971 scientist profiles identified from a variety of bibliometric data sources across all scientific disciplines. From this pool, a subset of 70 scientists specializing in Plant Science and Agronomy were carefully analyzed. To qualify for inclusion in this ranking, a candidate was required to meet the following conditions:
- A minimum D-index of 30, ensuring only researchers with substantial disciplinary impact were considered;
- A majority of tier-level publications had to be within the field of Plant Science and Agronomy, confirming the researcher’s focused contribution to this discipline;
- Recognition of awards and achievements pertinent to Plant Science and Agronomy, acknowledging scholarly excellence beyond bibliometric indicators.
It is important to note that the D-index threshold for top researcher consideration is dynamically set, increasing in increments of 10 according to the total number of scholars estimated within each discipline. This ensures that the ranking consistently includes the top 1% of leading experts, maintaining exclusivity and relevance. Additionally, to guarantee disciplinary coherence, the proximity between a scientist’s general H-index and their D-index is maintained at 30% or less, reflecting a focused research portfolio.
Verification Practices and Methodology Transparency
Understanding the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team conducted meticulous manual verification of all scientist profiles. This process involved cross-correlating information against publications indexed in a wide spectrum of trustworthy and domain-relevant sources to validate data accuracy.
Although the number of papers published in prominent journals and conference proceedings does not directly affect the ranking position, these metrics serve as valuable secondary indicators of a scientist’s research contributions within their specialization.
The authoritative ranking positions are established by employing each researcher’s D-index derived from data provided by OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases available to the global research community. For readers interested in a deeper understanding of the methodology employed, we invite consulting our methodology page, which details the procedures and analytical frameworks used.
