Data Sources and Citation Metrics
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Tunisia Ranking is primarily based on bibliometric data from OpenAlex and CrossRef, complemented by multiple other reputable data sources. The comprehensive citation-based metrics used to devise this ranking were collected on January 12, 2026. Each scientist's position in the ranking is determined by their D-index (Discipline H-index), which considers only the papers and citations pertinent exclusively to the examined discipline, ensuring a focused and relevant evaluation of research impact within Plant Science and Agronomy.
Scope and Criteria of the Ranking
The ranking encompasses an extensive analysis of 279,971 scientist profiles derived from a range of bibliometric data sources across all scientific disciplines. Within this universe, 10 scientists specifically engaged in Plant Science and Agronomy in Tunisia were examined. To qualify for inclusion in the ranking, a scientist's D-index must be at least 30, and the majority of their top-tier publications must pertain directly to Plant Science and Agronomy. Additionally, consideration is given to awards and notable achievements within this field. The D-index threshold for selecting top researchers is calibrated in increments of 10, relative to the total estimated number of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading scholars while maintaining a proximity threshold where the difference between a scientist's overall H-index and their discipline-specific D-index does not exceed 30%.
Verification and Validation Practices
Recognizing that raw bibliometric data should not be treated as an absolute measure of scholarly productivity, the researchers responsible for this ranking conducted thorough manual verification of all scientist profiles. These profiles were cross-correlated against publications documented in a broad spectrum of trustworthy and authoritative sources to enhance accuracy. While the number of publications in prominent journals and prestigious conference proceedings is not a direct factor in ranking position, it serves as a valuable secondary indicator of a scientist’s contributions within the scientific community. The ranking itself is established strictly using the D-index based on reliable data sourced from OpenAlex and CrossRef—two of the most prominent and respected bibliometric databases accessible to the global research community.
