The bibliometric data used to calculate the citation-based metrics integral to this ranking were extracted on January 12, 2026. Each scientist's position within the ranking is determined by their Discipline H-index, or D-index, which specifically reflects citation metrics and publication output strictly within the examined field of Plant Science and Agronomy. This discipline-specific focus allows for a refined and relevant assessment of scholarly influence.
Scope and Criteria of the Ranking
The ranking’s scope was defined through the examination of 279,971 scientist profiles sourced from a diverse set of bibliometric databases, spanning across all academic disciplines. Within Plant Science and Agronomy specifically, 5 leading scientists were identified and thoroughly evaluated for inclusion.
To qualify for this ranking, each scientist was required to have a minimum D-index of 30, ensuring a substantive research footprint within the discipline. Additionally, a majority of their tier publications had to be distinctly categorized under Plant Science and Agronomy to reflect focused expertise. Beyond citation metrics, special consideration was given to scientists’ awards and notable achievements relevant to the field.
The threshold for D-index consideration was adjusted in increments of 10, based on the estimated total number of scholars within each discipline. This approach guarantees the inclusion of the top 1% of leading experts in the respective area of research. Importantly, candidates’ general H-index and their D-index values were expected to be within 30% proximity, further affirming their sustained commitment to the discipline under review.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture scholarly contributions, the assembly of this ranking incorporated thorough manual verification processes. Each researcher’s profile was carefully cross-checked against publications documented in a broad array of reputable scholarly sources. This diligence ensures that the ranking accurately reflects genuine research influence and contribution.
Although the quantity of papers published in prominent journals and conference proceedings was not directly factored into ranking positions, it serves as a valuable secondary indicator of a scientist’s active engagement and impact within Plant Science and Agronomy.
Fundamentally, the ranking positions are derived from each scientist’s D-index, calculated from data provided by OpenAlex and CrossRef—the most prominent, reliable, and respected bibliometric databases accessible to the global research community.
