A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation counts within the examined discipline. This ensures that the evaluation reflects a researcher's specific impact and contribution to the field of Plant Science and Agronomy rather than their overall research output across unrelated fields.
Scope of Research and Inclusion Criteria
Our analysis began with 279,971 scientist profiles identified across a broad spectrum of disciplines from diverse bibliometric databases. From this vast dataset, 30 scientists specializing in Plant Science and Agronomy in Iran were specifically examined for inclusion in the ranking.
To qualify for the ranking, a scientist must satisfy the following criteria:
- Maintain a D-index of at least 30 within the domain of Plant Science and Agronomy.
- Have a majority of their tier publications classified under Plant Science and Agronomy.
- Exhibit notable awards and achievements relevant to Plant Science and Agronomy.
The threshold D-index for top researcher consideration is set in increments of 10 and calibrated according to the estimated total number of scholars in each discipline. This method assures the inclusion of the top 1% of leading scholars in the field. Furthermore, to maintain the disciplinary focus of the ranking, candidates’ general H-index and their D-index must differ by no more than 30%, signifying a strong and consistent contribution to the discipline under review.
Additional Verification and Validation Practices
We recognize that raw bibliometric data alone is insufficient to fully capture the quality and impact of scientific contributions. Consequently, all scientist profiles included in the ranking underwent thorough manual verification. This cross-referencing process involved comparing publication records with multiple trustworthy and authoritative sources to ensure the accuracy and integrity of the data presented.
While the number of publications in prominent journals and conference proceedings does not directly influence the ranking position, it serves as an important secondary indicator of a scientist’s active contribution and recognition within Plant Science and Agronomy.
The ranking positions are established on the basis of each researcher's D-index calculated from data aggregated primarily from OpenAlex and CrossRef, the foremost bibliometric databases currently accessible to the research community.
