Researchers’ positions within the ranking are determined by their Discipline H-index, often referred to as the D-index. Unlike a standard H-index, the D-index specifically accounts only for publications and citation metrics relevant to the examined discipline—in this case, Plant Science and Agronomy—thereby offering a more precise measure of impact within the field.
Scope of Research Coverage
Our analysis encompassed a total of 279,971 scientist profiles drawn from a wide array of bibliometric data sources across all scientific disciplines. Within this broad dataset, 22 scientists specializing in Plant Science and Agronomy were identified and evaluated. To qualify for inclusion in the ranking, a researcher’s D-index had to meet or exceed a threshold of 30, and the majority of their tier publications had to be focused explicitly on Plant Science and Agronomy.
Furthermore, recognitions such as prestigious awards and notable achievements in these disciplines were integrated into the selection process as qualitative factors, enhancing the depth of evaluation. The D-index threshold is determined dynamically, adjusted in increments of 10 relative to the estimated total number of scholars within each discipline. This approach ensures the consistent representation of the top 1% of leading scholars while maintaining disciplinary relevance. Additionally, candidates were required to demonstrate a proximity of 30% or less between their general H-index and their D-index, ensuring their research focus aligns closely with the discipline under review.
Verification and Additional Evaluation Practices
At Research.com, we recognize that raw bibliometric data alone cannot fully or definitively evaluate the scholarly contributions of researchers. Consequently, all scientist profiles included in the ranking underwent meticulous manual verification and were cross-correlated against publications listed in a broad spectrum of credible and authoritative sources. This rigorous validation process safeguards the integrity and accuracy of the ranking.
While the quantity of publications in prominent journals and conference proceedings does not directly influence the positioning within the ranking, it serves as an important secondary indicator of a scientist’s influence and engagement in their specialized area of research. The primary determinant remains each researcher's D-index, derived from data gathered through OpenAlex and CrossRef.
