A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only publications and citation counts directly relevant to the examined discipline. This discipline-specific H-index enables a more precise evaluation of a researcher’s impact within the field of Plant Science and Agronomy, rather than across all research outputs.
Scope and Inclusion Criteria
The ranking was developed by examining 279,971 scientist profiles identified across a wide spectrum of bibliometric databases and covering all areas of scientific inquiry. Within this extensive dataset, 1,000 scientists specifically engaged in the discipline of Plant Science and Agronomy were analyzed in detail.
To qualify for inclusion in the ranking, a scientist must have a minimum D-index of 30, ensuring that only those with substantial scholarly influence in the field are considered. Beyond the quantitative threshold, the majority of a qualifying researcher’s most highly tiered publications must focus on Plant Science and Agronomy. Additionally, awards and notable achievements relevant to the discipline were also taken into account as qualitative indicators of expertise and impact.
The D-index threshold is dynamically set in increments of 10 according to the estimated total number of active scholars within each discipline. This approach guarantees that the ranking consistently captures the top 1% of leading experts within the field, providing a credible representation of elite researchers. Furthermore, alignment between a scientist’s general H-index and their discipline-specific D-index was scrutinized, requiring a proximity of 30% or less to confirm specialization and consistent scholarly impact within Plant Science and Agronomy.
Verification Practices and Data Integrity
Recognizing the limitations inherent in raw bibliometric data, the researchers responsible for this ranking employed rigorous manual verification protocols to complement automated data collection. Each scientist’s profile was carefully reviewed and cross-correlated against publications indexed in a broad range of trusted academic sources. This meticulous validation process aims to ensure accuracy and reliability beyond what citation data alone can provide.
While the number of publications in leading journals and conference proceedings does not directly affect a researcher’s ranking position, it serves as a valuable secondary indicator of scholarly contribution and stature within Plant Science and Agronomy.
Researchers’ ranks are calculated based on the D-index sourced from OpenAlex and CrossRef — the most authoritative and accessible bibliometric databases available to the global research community.
