Bibliometric data for computing the citation-based metrics featured in this ranking were collected on January 12, 2026. The ranking methodology centers on the D-index (Discipline H-index), a refined metric that accounts only for publications and citations specifically within the domain under review. This ensures a precise evaluation of each scientist's impact within Plant Science and Agronomy, rather than a generalized citation count across all disciplines.
Scope of Research and Selection Criteria
Our analysis examined a comprehensive pool of 279,971 scientist profiles from a wide array of bibliometric sources spanning all scientific disciplines. Within this broad dataset, 12 scientists specializing in Plant Science and Agronomy in Kenya were identified and evaluated.
To qualify for inclusion in the Plant Science and Agronomy ranking, candidates were required to meet stringent criteria:
- A D-index threshold of at least 30.
- A majority of tier publications concentrated explicitly within the Plant Science and Agronomy field.
- Recognition of pertinent awards and achievements within the discipline, reinforcing scholarly standing.
The D-index threshold employed to consider top researchers varies incrementally by 10, calibrated based on the estimated total number of active scholars within each discipline. This stratagem ensures that the top 1% of leading scholars in each area are represented. Moreover, to maintain disciplinary precision, there is a strict requirement that the difference between a scientist’s overall H-index and their D-index should be 30% or less, thereby assuring proximity in domain-specific impact relative to their broader scientific output.
Additional Verification Practices
Recognizing that raw bibliometric data, while foundational, cannot serve as the sole measure of scholarly contribution, the Research.com team employed rigorous manual verification of all scientist profiles. Each profile was cross-correlated against publications in an extensive selection of trustworthy and authoritative sources to validate accuracy and affiliation.
Although not incorporated directly into the researcher's ranking position, the quantity of publications in prominent journals and prestigious conference proceedings was considered an important secondary indicator of a scientist's influence and contribution within their specific research domain.
The final ranking position is determined using the D-index metric derived specifically from information gathered through OpenAlex and CrossRef—widely acknowledged as the most prominent and reliable bibliometric databases available to the global research community.
