Bibliometric data, essential for calculating the citation-based metrics employed in this ranking, were collected with a cutoff date of January 12, 2026. Each scientist's position in the ranking is determined by their D-index (Discipline H-index), which is a refined metric that evaluates research output exclusively within the Plant Science and Agronomy discipline, thus focusing on relevant publications and corresponding citations within this field.
Scope of Research and Qualification Criteria
The ranking process examined 279,971 scientist profiles across all scientific disciplines, identifying 268 specialists within Plant Science and Agronomy. To qualify for inclusion in this ranking, a scientist was required to have a D-index of at least 30, with the majority of their tier publications concentrated in Plant Science and Agronomy.
Additionally, consideration was given to scientists’ awards and notable achievements in the domain, providing a qualitative complement to bibliometric measures. The D-index thresholds are set intelligently based on the estimated population size for each discipline, increasing in increments of 10, to ensure that the top 1% of leading scholars are systematically recognized. Furthermore, to maintain disciplinary focus, a strict criterion is enforced whereby a scientist’s general H-index and their D-index must differ by no more than 30%, preserving the relevance of their primary research contributions.
Verification and Quality Assurance
We are fully aware that raw bibliometric data alone cannot serve as an absolute measure of research output or quality. Consequently, every scientist profile included in the ranking was manually verified through thorough cross-correlation against publications indexed in a broad range of trustworthy and reputable sources. While the number of papers published in prestigious journals and conference proceedings does not directly affect a researcher's ranking position, it remains a valuable secondary indicator of a scientist’s scholarly contribution within Plant Science and Agronomy.
The ranking position ultimately derives from the D-index computed using data gathered from OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases currently accessible to the research community.
