A researcher's position within this ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation records that fall strictly within the examined discipline. This approach allows for a nuanced and discipline-focused evaluation of scholarly impact, avoiding the distortions that may arise from contributions outside of Plant Science and Agronomy.
Scope of Research and Ranking Criteria
The ranking process involved a rigorous examination of 279,971 scientist profiles aggregated from diverse bibliometric data sources spanning all fields of research. Specifically, for the Plant Science and Agronomy discipline, the ranking focuses on 1,201 scientists identified as active contributors in this area.
To qualify for inclusion, a scientist’s D-index had to meet or exceed a threshold of 30, and the majority of their tier publications needed to be within the Plant Science and Agronomy domain. Additionally, consideration was given to awards and significant achievements within the discipline, reflecting both quantitative and qualitative measures of excellence.
The D-index threshold is calibrated as increments of 10 relative to the estimated total number of scholars per discipline, with the key intent of encompassing the top 1% of leading scientists in the field. Further, to ensure consistency and disciplinary relevance, the proximity between a scientist’s general H-index and their D-index must remain within 30% or less.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone cannot provide an absolute evaluation of scholarly output, the Research.com team undertook extensive manual verification of all scientist profiles. Each profile was carefully cross-checked against publications listed in a wide array of trustworthy sources to validate the authenticity and relevance of the data.
While the number of publications in prestigious journals and conference proceedings does not directly influence the final ranking position, it is regarded as a valuable secondary indicator of a scientist’s contributions to Plant Science and Agronomy.
The definitive ranking order is established via each researcher’s D-index as derived from data curated primarily from OpenAlex and CrossRef, two of the most prominent and reliable bibliometric databases accessible to the global research community.
