Data Sources Utilized for the Ranking
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Egypt Ranking is based primarily on data aggregated from OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases available to the global research community. In addition to these core sources, multiple other data repositories have been integrated to provide a comprehensive and nuanced foundation for the citation-based metrics employed. The bibliometric data used to devise the citation-based indicators were meticulously collected on 2026-01-12, ensuring that the information reflects the most current and relevant outputs and citations available at the time of analysis.
The ranking methodology centers on a researcher’s D-index (Discipline H-index), which is a refined bibliometric metric calculated exclusively from a scholar’s papers and citations within the specified discipline of Plant Science and Agronomy. This focus ensures that the ranking reflects impact and productivity specifically in the examined field rather than a general research footprint.
Scope of Research and Eligibility Criteria
For this edition, 279,971 scientist profiles extracted through a systematic review of various bibliometric sources across all disciplines were initially examined. From this large dataset, 14 scientists who specialize in Plant Science and Agronomy were identified for inclusion. To qualify for this ranking, candidates were required to have a D-index of at least 30, underscoring sustained and significant contributions within the discipline. Furthermore, the majority of tier publications attributed to each qualifying scientist must be clearly within Plant Science and Agronomy.
In addition to bibliometric thresholds, a scientist’s awards and professional achievements relevant to Plant Science and Agronomy were also considered as supplementary indicators of distinction and contribution to the field. The D-index threshold of 30 is established as part of a scalable framework where the minimum required D-index increases by increments of 10 in correlation with the total number of scholars estimated within each discipline. This framework ensures that the ranking consistently captures the top 1% of leading experts while maintaining disciplinary relevance. An additional quality control measure requires that the difference between the scientist’s general H-index and their D-index does not exceed 30%, preserving focus on domain-specific impact.
Verification and Validation Practices
The team responsible for creating this ranking acknowledges that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s research output or influence. To mitigate this limitation, all scientist profiles included were manually verified by cross-correlating publication records against a broad spectrum of trustworthy sources. This rigorous validation process enhances the accuracy and reliability of the ranking.
It is important to note that while the number of papers published in leading journals and prominent conference proceedings does not directly influence the position in the Research.com ranking, such metrics are recognized as valuable secondary indicators of a scientist’s contribution to advancing research within Plant Science and Agronomy.
The ranking positions are ultimately established based on the D-index, with the underlying data derived from OpenAlex and CrossRef. These databases are widely regarded as authoritative sources for bibliometric analyses, lending credibility and transparency to the methodology employed.
