Best Plant Science and Agronomy Scientists 2026 in Thailand

A critical metric underpinning scientist positioning within the ranking is the D-index (Discipline H-index). Unlike a general H-index, the D-index isolates and quantifies the research output and citation impact specific to the discipline under examination—in this case, Plant Science and Agronomy. This discipline-specific focus enhances the precision of ranking by concentrating solely on contributions relevant to the targeted scientific area.

Scope of Research and Eligibility Criteria

To construct this ranking, a comprehensive examination was performed on 279,971 scientist profiles derived from a wide array of bibliometric data sources encompassing all scientific disciplines. Within this broad corpus, 10 scientists specifically recognized for their contributions to Plant Science and Agronomy in Thailand were thoroughly evaluated.

Eligibility for inclusion in the ranking necessitated a minimum D-index threshold of 30. Furthermore, a qualifying scientist’s portfolio required a majority of tier publications to be firmly situated within Plant Science and Agronomy. Awards and notable achievements explicitly within the discipline were also factored into the assessment, adding an additional qualitative dimension to the ranking process.

It is important to note that the D-index threshold is calibrated in increments of 10 relative to the estimated total number of scholars per discipline, thereby guaranteeing that approximately the top 1% of leading experts within the field are incorporated. To ensure relevance and specificity, a proximity constraint was applied whereby the difference between a scientist’s general H-index and their D-index does not exceed 30%, reinforcing the focus on discipline-centered impact.

Verification and Validation Practices

The Research.com team acknowledges that raw bibliometric data alone cannot serve as a definitive measure of scholarly output or influence. Consequently, all scientist profiles featured in this ranking underwent rigorous manual verification. This process involved cross-correlating publication records against a broad spectrum of trustworthy sources to confirm accuracy and authenticity.

While the number of papers published in high-impact journals and prestigious conference proceedings does not directly affect a researcher’s ranking position, these publication counts serve as a valuable secondary indicator of scholarly contribution within Plant Science and Agronomy.

Positions in the ranking are ultimately established based on each researcher’s D-index, derived from OpenAlex and CrossRef data. These databases are among the most prominent and respected in the research community, ensuring the reliability and credibility of the metrics used.
