A scientist’s position in the ranking is determined by their D-index (Discipline H-index). Unlike a general H-index, the D-index specifically includes only papers and citations within the examined discipline of Plant Science and Agronomy, thereby providing a more focused and relevant measure of research impact in the field.
Scope of Research and Eligibility Criteria
The ranking reviewed a total of 279,971 scientist profiles across all scientific disciplines identified from diverse bibliometric data sources. Within the specific domain of Plant Science and Agronomy, 18 scientists were carefully examined. To qualify for inclusion in the ranking, each scientist was required to meet a minimum D-index threshold of 30. Furthermore, the majority of an eligible scientist’s tier publications had to be within the Plant Science and Agronomy discipline.
In addition to bibliometric criteria, consideration was also given to scientists’ awards and achievements within the field, ensuring holistic recognition of academic excellence. The threshold for the D-index is calibrated as increments of 10, proportional to the estimated total number of scholars within each discipline, while guaranteeing inclusion of the top 1% of leading researchers. To maintain disciplinary relevance, the proximity between a scientist’s general H-index and their D-index must not exceed 30%.
Verification and Quality Assurance
The Research.com team recognizes that raw bibliometric data alone cannot fully represent the multifaceted contributions of scholars. Accordingly, all scientist profiles were manually verified and rigorously cross-correlated against publications across a wide spectrum of credible and authoritative sources. This meticulous process reinforces the accuracy and reliability of the ranking.
While not directly factored into the ranking position, the number of papers published in prominent journals and conference proceedings serves as an important secondary signal of a scientist’s research contribution within Plant Science and Agronomy.
Ultimately, the position in the ranking is established through the researcher’s D-index calculated from data aggregated by OpenAlex and CrossRef — among the most prominent and trusted bibliometric databases accessible to the global research community.
