Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Bangladesh Ranking has been compiled using robust bibliometric data primarily sourced from OpenAlex and CrossRef, complemented by multiple other reputable data repositories. The citation-based metrics integral to this ranking were gathered on January 12, 2026, ensuring a recent and comprehensive snapshot of scholarly output within the discipline. These metrics provide the foundation for the D-index (Discipline H-index) employed to position each scientist, a measure that incorporates only publications and citation data relevant to Plant Science and Agronomy.
Scope of Research and Criteria for Inclusion
The ranking derives from an extensive examination of 279,971 scientist profiles aggregated across various bibliometric sources, spanning all scientific disciplines. Within Plant Science and Agronomy specifically, 6 scientists were identified for inclusion based on stringent qualification criteria. To qualify, a researcher must have attained a D-index of at least 30, with the majority of their tier publications explicitly within the domain of Plant Science and Agronomy. Additionally, demonstrated awards and distinguished achievements in this field were considered as part of the evaluative process.
The threshold for the minimum D-index is dynamically calibrated in increments of 10 in accordance with the estimated total number of scholars per discipline, ensuring that the top 1% of leading experts are encapsulated within the list. Furthermore, a requisite proximity of 30% or less between a scientist’s overall H-index and their D-index maintains consistency in disciplinary specificity and overall impact.
Verification and Methodological Rigor
Understanding the inherent limitations of raw bibliometric data, the Research.com team undertakes meticulous manual verification and cross-correlation of all scientist profiles against publications indexed in a wide array of trustworthy and authoritative sources. While the ranking position is principally determined by the D-index calculated from OpenAlex and CrossRef data—the foremost bibliometric databases accessible to the global research community—we recognize that additional factors such as the number of publications in leading journals and conference proceedings serve as valuable supplementary indicators of a scientist’s contributions.
This multi-layered approach ensures the ranking’s integrity and reliability, reinforcing that metrics are contextualized rather than absolute measures. For a detailed overview of the methodology underlying this ranking, we invite readers to visit our methodology page.
