Data Sources Utilized for the Ranking
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Ghana Ranking is compiled using comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other prestigious academic data repositories. These platforms provide broad and reliable metadata on scholarly publications and citations, enabling accurate and up-to-date insight into researchers' impact within their disciplines. The bibliometric data underpinning the citation-based metrics for the ranking were meticulously collected on January 12, 2026. A scientist's rank within this list is determined by their D-index (Discipline H-index), a specialized metric that exclusively evaluates papers and citation impact within the specific discipline under review—in this case, Plant Science and Agronomy.
Scope of Research and Eligibility Criteria
The ranking considers a comprehensive dataset comprising 279,971 scientist profiles drawn from multiple bibliometric sources across all scientific disciplines. Within the scope of Plant Science and Agronomy, specifically, 2,000 scientists were analyzed. To qualify for inclusion in the ranking, a researcher must meet several stringent criteria. First, their D-index must be at least 30, ensuring demonstrated excellence and impact within the discipline. Additionally, the majority of their tier publications must be concentrated in Plant Science and Agronomy, highlighting their dedicated focus in this area. Beyond bibliometric indicators, scientists’ awards and notable achievements within the field also contribute to their evaluation.
The threshold for the D-index is dynamically set in increments of 10 commensurate with the estimated total number of scholars in each discipline, thereby accommodating differences in field size while ensuring that the top 1% of leading scientists are consistently represented. Furthermore, a required proximity of 30% or less between a scientist’s general H-index and their D-index is maintained to validate that their overall impact aligns closely with their influence within Plant Science and Agronomy.
Verification and Assessment Methodology
Recognizing that raw bibliometric data alone cannot fully capture the quality and contribution of scholars, Research.com employs a rigorous manual verification process. Expert analysts cross-correlate scientist profiles against a wide array of trustworthy publication databases and academic sources to confirm accuracy and validity. While the ranking position is determined solely by each researcher’s D-index, additional indicators such as the number of publications in prominent journals and leading conference proceedings serve as valuable secondary evidence of a scientist’s influence and contribution within their field.
The position of each researcher in the ranking is rigorously established using data exclusively from OpenAlex and CrossRef, which represent the preeminent and widely accepted bibliometric resources available to the global research community. We invite readers interested in a detailed overview of the methodology to consult our methodology page for further information.
