A scientist’s position within the ranking is determined by their Discipline H-index, or D-index—a metric that exclusively considers publications and citation counts within the examined discipline of Plant Science and Agronomy. This methodology allows for a focused and fair comparison of researchers based on their specialized scholarly output.
Scope of Research and Inclusion Criteria
The ranking comprehensively examined 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources covering all academic disciplines. Within the scope of Plant Science and Agronomy specifically, six scientists were assessed to establish the ranking. To qualify for inclusion, a scientist’s D-index needed to be at least 30, ensuring a threshold of significant disciplinary impact. Moreover, a majority of each scientist’s tier publications had to be rooted in the Plant Science and Agronomy field.
In addition to bibliometric measures, awards and other notable achievements in Plant Science and Agronomy were considered to provide a well-rounded evaluation of each researcher’s contribution. The D-index threshold used to select top researchers is adapted in increments of 10, calibrated to the estimated total number of scholars in each respective discipline, while ensuring that the top 1% of leading scientists are incorporated in the list. For consistency and disciplinary alignment, a researcher’s general H-index and their D-index were required to have a proximity difference of 30% or less.
Verification and Methodological Rigor
Recognizing the limitations inherent in raw bibliometric data as the sole evaluative tool, the team behind this ranking undertook meticulous manual verification of all scientist profiles. This process involved cross-correlating publication records against a wide range of trustworthy and authoritative sources to ensure accuracy and reliability.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it serves as a valuable supplementary indicator of a scientist’s contribution to the field. The primary basis for ranking remains the D-index calculated from data obtained from OpenAlex and CrossRef, among the most prominent and widely respected bibliometric databases available to the research community today.
