Data Sources and Metrics
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Saudi Arabia Ranking is based on comprehensive bibliometric data aggregated primarily from OpenAlex and CrossRef, alongside multiple other reputable data sources. The citation-based metrics used to determine a scientist's standing in the ranking were collected and consolidated on January 12, 2026. Central to the ranking methodology is the use of the D-index (Discipline H-index), a refined variation of the traditional H-index that considers only publications and citation metrics strictly relevant to the examined discipline. This approach ensures a focused and accurate representation of each researcher’s impact within the field of Plant Science and Agronomy.
Scope of Research and Eligibility Criteria
A total of 279,971 scientist profiles identified from diverse bibliometric databases spanning all academic disciplines were rigorously examined. Within this vast dataset, 22 scientists specializing in Plant Science and Agronomy were singled out for inclusion in the ranking. To qualify, a scientist was required to have a minimum D-index of 30, demonstrating substantial citation impact in the discipline. Additionally, the majority of their tier publications needed to be categorized within Plant Science and Agronomy, ensuring domain-relevant expertise. Recognition of awards and achievements pertinent to this field also contributed to the assessment process.
The D-index threshold is calibrated incrementally by steps of 10, adjusted according to the estimated total number of scholars in each discipline. This methodology guarantees the inclusion of the top 1% of leading scholars, thereby maintaining an elite and relevant listing. Furthermore, the difference between a scientist’s general H-index and their D-index was maintained at 30% or less, ensuring alignment between their overall research profile and disciplinary impact.
Verification and Data Integrity
Understanding the limitations of raw bibliometric data as an absolute measure of scholarly output, the research team conducted meticulous manual verification of all scientist profiles. Each profile was cross-referenced against publications indexed in a broad array of trusted sources to uphold data integrity. Although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it serves as a valuable secondary indicator of scientific contribution within the field.
The authoritative position of each scientist within the ranking is established based on their D-index, with data drawn from OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric platforms accessible to the global research community.
