Data Sources and Metrics
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Poland Ranking is primarily based on comprehensive bibliometric data aggregated from OpenAlex and CrossRef, supplemented by multiple additional data sources to ensure robustness and accuracy. The citation-based metrics utilized in the ranking were collected on January 12, 2026. Central to this ranking methodology is the use of each scientist’s D-index (Discipline H-index), which uniquely focuses on metrics derived solely from publications and citations within the examined discipline, providing a precise measure of a researcher's impact in Plant Science and Agronomy.
Scope of Research and Inclusion Criteria
The ranking reflects an exhaustive evaluation of 279,971 scientist profiles drawn from a diverse array of bibliometric data repositories spanning all disciplines, among which 25 researchers specifically active in Plant Science and Agronomy were thoroughly examined. To qualify for inclusion in this ranking, researchers were required to meet a minimum D-index threshold of 30. Additionally, a majority of their tier publications had to be published within Plant Science and Agronomy, ensuring the disciplinary focus of their scholarly contributions. Awards and professional achievements related to Plant Science and Agronomy were also considered as an important qualitative factor.
The threshold for the D-index is dynamically determined in increments of 10 based on the estimated total number of scholars in each discipline. This calibration guarantees that the top 1% of leading scholars are consistently represented within the ranking. Furthermore, to ensure disciplinary specialization, a candidate’s general H-index and D-index must have a proximity variance of 30% or less.
Additional Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot fully capture a researcher's scientific contribution, the Research.com team undertakes rigorous manual verification of all scientist profiles. Each profile is meticulously cross-correlated with publications from a broad spectrum of authoritative and trustworthy sources to validate accuracy and authenticity. Although the final rank position is determined solely by the D-index, the number of publications in prestigious journals and conference proceedings is considered a valuable secondary indicator of scholarly impact within Plant Science and Agronomy.
The use of OpenAlex and CrossRef—the most prominent and reputable bibliometric databases accessible to the research community—underscores the credibility and transparency of the ranking methodology.
