A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric metric that considers only the publications and citation impact that are strictly within the examined discipline of Plant Science and Agronomy. This approach ensures that the ranking reflects each researcher's specific contributions to the field, effectively capturing discipline-focused scholarly influence.
Scope of Research and Selection Criteria
The ranking analysis began by examining 279,971 scientist profiles drawn from an extensive array of bibliometric data sources across all disciplines. Within Plant Science and Agronomy specifically, 22 scientists were identified for detailed evaluation.
To qualify for inclusion in this ranking, a scientist must meet two key criteria:
- Possess a D-index of at least 30 within the Plant Science and Agronomy discipline.
- Have a majority of their tier publications concentrated in Plant Science and Agronomy, ensuring a significant focus in this research domain.
In addition to bibliometric performance, a scientist’s awards and professional achievements in Plant Science and Agronomy are also taken into account to complement the citation data.
The D-index threshold for consideration is calibrated incrementally by 10 points, depending on the estimated total number of active scholars in the discipline, to maintain methodological consistency. This approach guarantees inclusion of the top 1% of leading scholars in the list while maintaining rigorous standards. Furthermore, a crucial quality control measure ensures that the proximity between a scientist’s general H-index and their D-index remains within 30%, confirming the researcher’s specialization in the field.
Verification and Validation Procedures
Research.com fully recognizes that raw bibliometric data alone cannot perfectly represent the full scope of scholarly output or impact. Consequently, all scientist profiles included in the ranking underwent meticulous manual verification. This involved cross-correlating author records and publications against a broad spectrum of trustworthy academic sources, ensuring accuracy and eliminating potential misattributions.
While the number of articles published in prominent journals and conference proceedings is not a direct determinant of ranking position, it nevertheless serves as a valuable secondary signal reflecting a researcher’s substantive contributions within the Plant Science and Agronomy field.
The final positions in the ranking are strictly established using each researcher’s verified D-index computed from the bibliometric information gathered from OpenAlex and CrossRef—arguably the most prominent and widely utilized databases within the research community.
