Institutional positions in the ranking are determined by aggregating the D-indexes (Discipline H-index) of all qualifying scholars affiliated with an institution whose primary research is in Plant Science and Agronomy. The D-index metric is discipline-specific and exclusively reflects publications and citations within the evaluated field, ensuring that only subject-relevant academic contribution is considered.
Scope of Research and Selection Criteria
The scope of research for this ranking was extensive: a total of 279,971 scientist profiles were scrutinized from a diverse array of bibliometric sources. Specifically, 14,876 scientists whose primary focus is Plant Science and Agronomy were analyzed.
- A minimum D-index threshold of 30 was established for considering each scientist, with the majority of their top-tier publications required in Plant Science and Agronomy.
- Additional consideration was given to scientists’ awards and achievements within this field.
- The threshold for top researchers is dynamically set in increments of 10 according to the overall number of specialists per discipline, with the methodology ensuring that the top 1% of leading scholars are always incorporated.
- An additional proximity requirement ensures a 30% or less difference between a researcher’s general H-index and D-index, affirming focused expertise in the evaluated discipline.
Awards and field-specific achievements serve as significant qualitative factors, ensuring recognition of both academic output and broader impact in Plant Science and Agronomy.
Verification Practices and Data Integrity
The team behind the Research.com ranking recognizes that quantitative data such as raw bibliometric indices are not absolute tools for evaluating scholarly output. To enhance reliability, all scientist profiles underwent manual verification and were cross-referenced with publications listed in a range of trusted, authoritative databases.
While the number of publications in top-tier journals and proceedings is not directly used to calculate ranking positions, it remains a valuable indicator of a researcher’s scientific footprint in their respective field. Ultimately, the key ranking positions are determined through each researcher’s H-index data as consolidated from OpenAlex and CrossRef, currently considered premier bibliometric resources by the academic community.
