The bibliometric data used to devise the citation-based metrics incorporated in this ranking were collected on January 12, 2026. A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that includes only publications and citations pertinent to the evaluated discipline. This ensures that the ranking specifically reflects scholarly impact within Plant Science and Agronomy, rather than general citation performance.
Scope and Selection Criteria
The ranking analyzed a total of 279,971 scientist profiles across all disciplines based on data aggregated from various bibliometric sources. Focusing specifically on Plant Science and Agronomy, 57 scientists were identified and rigorously evaluated.
To qualify for inclusion in this ranking, scientists were required to meet a minimum D-index threshold of 30, where a majority of their tier publications are firmly situated within Plant Science and Agronomy. Additionally, awards and notable achievements within this field were factored in to reflect both quantitative impact and qualitative recognition.
The D-index threshold is dynamically calibrated in increments of 10, relative to the estimated total number of active scholars in each discipline. This method ensures the representation of the top 1% of leading experts, providing a meaningful and selective overview of preeminent researchers. Furthermore, eligible scientists demonstrate a proximity of 30% or less between their overall H-index and discipline-specific D-index, underscoring the discipline-centric focus of this ranking.
Additional Verification Practices
Recognizing that raw bibliometric data alone can never fully capture the nuances of scientific contributions, the Research.com team undertook thorough manual verification of all scientist profiles. Each profile was cross-correlated against an extensive array of reputable sources to authenticate publication records and achievements. This meticulous process ensures that the ranking reflects accurately verified and reliable information.
While not a direct factor influencing placement in the ranking, the quantity of papers published in prominent journals and conference proceedings serves as a valuable secondary signal of a scientist's research contributions within Plant Science and Agronomy. The primary ranking metric, the D-index, remains anchored in the rigorously gathered data from OpenAlex and CrossRef.
