A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that accounts exclusively for publications and citations relevant to the specific discipline under examination—in this case, Plant Science and Agronomy. This approach ensures that the ranking accurately reflects scholarly impact within the targeted field, rather than overall citation performance across unrelated disciplines.
Scope of Research and Qualification Criteria
The ranking is based on a thorough analysis of a broad dataset consisting of 279,971 scientist profiles identified from a range of bibliometric data sources spanning all scientific disciplines. From this pool, 164 scientists whose research predominantly lies within Plant Science and Agronomy were specifically evaluated.
To qualify for inclusion in the ranking, a scientist must meet the following criteria:
- Their D-index must be at least 30.
- The majority of their tier publications must be within the field of Plant Science and Agronomy.
- Recognition of their awards and achievements within Plant Science and Agronomy was also incorporated as a supportive consideration.
The D-index threshold for delineating top researchers is dynamically set in increments of 10 based on the estimated total number of scholars within each discipline. This method guarantees that the ranking encompasses the top 1% of leading scholars by impact. Additionally, to ensure specificity and relevance, there is a threshold ensuring that the difference between a scientist’s general H-index and their D-index remains within 30% or less.
Verification Practices and Validation of Metrics
Our research team acknowledges that raw bibliometric data alone is insufficient as an absolute measure of scholarly contribution. Therefore, all scientist profiles were subjected to rigorous manual verification, including cross-correlation against a wide array of trusted publication sources to validate the authenticity and relevance of their research outputs.
While the number of papers published in prestigious journals and conference proceedings is not directly factored into the D-index or ranking position, it remains a valuable secondary indicator of a researcher’s influence and contribution within Plant Science and Agronomy.
The ranking itself is established based on each researcher’s D-index, using citation and publication information sourced primarily from OpenAlex and CrossRef—among the most prominent and reliable bibliometric databases accessible to the research community today.
