Data Sources and Citation Metrics
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Russia Ranking is primarily based on comprehensive bibliometric data collected from OpenAlex and CrossRef, alongside multiple other reputable data sources. These platforms represent some of the most prominent and well-curated scholarly databases available to the research community. The citation-based metrics used to develop this ranking were obtained from a snapshot of data collected on January 12, 2026. A key metric utilized for determining each scientist’s position in the ranking is the D-index (Discipline H-index), which is uniquely calculated using only those papers and corresponding citation metrics attributable to the examined discipline of Plant Science and Agronomy.
Scope of Research and Qualification Criteria
In creating the ranking, a total of 279,971 scientist profiles were examined from a variety of bibliometric data sources across all scientific disciplines. Specifically focusing on Plant Science and Agronomy, eight top scientists were identified based on stringent criteria. To qualify for inclusion, researchers were required to have a D-index of at least 30, ensuring a high level of scholarly impact within the discipline. Additionally, the majority of their tier publications had to be concentrated in Plant Science and Agronomy. Recognition of scientists’ awards and notable achievements within the field also played a supportive role in the evaluation process.
The threshold for the D-index is strategically set with increments of 10, reflecting the estimated total number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading researchers, thereby maintaining a rigorous standard for excellence. Moreover, to maintain disciplinary relevance, a scientist’s D-index must be no less than 70% of their general H-index, preserving a proximity of 30% or less between these two indices. This ensures that ranking positions accurately reflect discipline-specific impact rather than general scientific productivity.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of a researcher’s contributions, the Research.com team has implemented meticulous manual verification and cross-correlation of all scientist profiles against publications indexed in a wide range of trustworthy and well-established sources. This added layer of validation serves to reinforce the reliability and credibility of the ranking outcomes.
While the quantity of papers published in prominent journals and conference proceedings is not a direct factor in determining a researcher’s rank, it is acknowledged as a valuable secondary indicator of scientific contribution to the Plant Science and Agronomy field. The ranking is fundamentally anchored in each scientist’s D-index, as compiled from information sourced mainly from OpenAlex and CrossRef—the foremost bibliometric databases recognized by the global research community.
