A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a specialized metric that accounts only for papers and citations within the specific discipline of Plant Science and Agronomy. This nuanced metric allows for a focus on disciplinary impact rather than general scholarly output, facilitating the identification of leading experts who have demonstrated significant influence in this domain.
Scope of Research Examined
In total, 279,971 scientist profiles identified from a variety of bibliometric databases were examined across all academic disciplines. Within the discipline of Plant Science and Agronomy specifically, 1,000 scientists were carefully considered for inclusion in the ranking. To qualify, a researcher’s D-index had to be at least 30, reflecting a threshold indicative of substantial disciplinary impact. Additionally, a majority of a scientist’s tier publications needed to fall squarely within Plant Science and Agronomy to ensure relevance and specialization.
Scientist awards and achievements within the field were also taken into account as supplementary measures of excellence and recognition by the scholarly community. The D-index threshold is dynamically set in increments of 10 according to the estimated total number of researchers in each discipline, ensuring that the ranking encompasses the top 1% of leading scholars in the field. Furthermore, to maintain a strong disciplinary focus, the ranking only includes scientists whose general H-index and D-index do not differ by more than 30%.
Additional Verification Practices
We recognize that raw bibliometric data alone can never serve as an absolute or exclusive indicator of a scholar’s output or impact. Consequently, each scientist profile included in this ranking underwent rigorous manual verification and was cross-correlated against publication records in a wide range of trustworthy academic sources. This step is critical to uphold the integrity and accuracy of the ranking results.
Although not a direct factor determining rank placement, the volume of papers published in prominent journals and conference proceedings is considered a valuable secondary signal reflecting a scientist’s contributions to Plant Science and Agronomy. The final position in the ranking is ultimately established based on each researcher’s D-index derived from data gathered via OpenAlex and CrossRef, which remain the most prominent and trustworthy bibliometric databases of their type.
