Data Sources and Metrics Utilized for the Ranking
The 5th edition of the Research.com Best Plant Science and Agronomy Scientists in Oman Ranking is founded on comprehensive bibliometric data primarily obtained from OpenAlex and CrossRef, complemented by multiple other reputable data sources. The citation-based metrics employed to determine the relative standings within this ranking were compiled on January 12, 2026. A scientist’s position is determined based on their D-index (Discipline H-index), a refined measure that accounts exclusively for publications and citations relevant to the specified discipline, thus ensuring precision and discipline-specific evaluation.
Scope and Criteria of Research Considered
The ranking draws from an extensive dataset comprising 279,971 scientist profiles aggregated across disciplines, focusing specifically on 4 scientists identified within the Plant Science and Agronomy domain in Oman. To qualify for inclusion, candidates were required to demonstrate a D-index of at least 30 alongside a predominance of tier publications rooted in Plant Science and Agronomy. Additionally, distinguished awards and achievements within the field contributed to the evaluation process.
The threshold for the D-index varies in increments of 10, calibrated according to the estimated total number of scholars within each discipline. This methodology ensures the incorporation of the top 1% of leading scholars per discipline. Furthermore, a critical inclusion criterion mandates that a scientist’s general H-index and D-index differ by no more than 30%, affirming a focused research contribution pertinent to Plant Science and Agronomy.
Additional Verification Practices
While bibliometric data provides a robust foundation, the researchers compiling this ranking acknowledge that raw quantitative measures alone cannot exhaustively capture scholarly impact. To reinforce accuracy and credibility, each scientist’s profile was meticulously manually verified and cross-correlated against publications indexed in a variety of trusted sources.
Although not directly influencing the ranking position, the volume of papers published in leading journals and conference proceedings is recognized as a valuable secondary indicator of scholarly contribution in a specific discipline.
The final position within this ranking remains grounded firmly in the D-index calculated from data curated by OpenAlex and CrossRef—datasets renowned for their breadth, currency, and reliability within the global research community.
