Data Sources and Bibliometric Foundations
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in China Ranking is built upon a robust compilation of bibliometric data primarily sourced from OpenAlex and CrossRef, complemented by multiple additional reputable data repositories. These sources collectively offer comprehensive, up-to-date scholarly metadata and citation information essential for rigorous analysis. The bibliometric data used to develop the citation-based metrics integral to this ranking were collected on January 12, 2026. A scientist’s position in the ranking hinges on their D-index (Discipline H-index), a metric that exclusively considers a researcher’s publications and citation metrics within the specific discipline of Plant Science and Agronomy, thus ensuring discipline-focused relevance and comparability.
Scope of Research and Inclusion Criteria
This ranking evaluates a broad dataset encompassing 279,971 scientist profiles extracted from diverse bibliometric sources across all disciplines. Within this dataset, 658 scientists specializing in Plant Science and Agronomy were specifically identified and examined in detail. To qualify for inclusion in the ranking, a scientist must have a D-index of at least 30, with a majority of their tier publications firmly situated in the area of Plant Science and Agronomy. Additionally, researchers’ awards and notable achievements in the field were incorporated as a qualitative measure. The threshold for the D-index among top researchers is calibrated as increments of 10 relative to the total number of scholars estimated per discipline. This approach ensures that the top 1% of leading scholars are faithfully represented in the list. Moreover, a proximity threshold requiring a difference of 30% or less between a scientist’s general H-index and their D-index was applied to align general and discipline-specific research impact.
Verification and Validation Procedures
Recognizing that raw bibliometric data alone cannot fully capture the multifaceted output of scholarly work, the research team behind this ranking conducts a thorough manual verification of all scientist profiles. This process includes cross-correlating publication records with a broad array of trustworthy sources to ensure accuracy and authenticity. While not directly factoring into the ranking, the number of papers published in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contribution to Plant Science and Agronomy research. Importantly, the assignment of ranking positions is based strictly on each researcher’s D-index derived from OpenAlex and CrossRef data—two of the most prominent and respected bibliometric databases accessible to the global research community.
