Best Plant Science and Agronomy Scientists in Portugal

The 2nd edition of ranking of the best scientists in the arena of Plant Science and Agronomy was created using data consolidated from multiple data sources including OpenAlex and CrossRef. The bibliometric data for estimating the citation-based metrics were gathered on 21-12-2022. Position in the ranking is based on a scientist's D-index (Discipline H-index), which only includes publications and citation data for an examined discipline.

The range of our Plant Science and Agronomy research’s best scholars ranking is a reliable lineup of leading scholars from the discipline of Plant Science and Agronomy, established by means of a thorough examination of 166,880 scholars determined from various bibliometric data sources. For the area of Plant Science and Agronomy, as many as 5065 researchers were investigated.

What is D-index inclusion threshold for Plant Science and Agronomy
The D-index threshold for approving a researcher to be examined is set to 30 if most of their publications are in the field of Plant Science and Agronomy. The approval criteria for researchers to be considered into the ranking of top scientists are based on the D-index, ratio of the contributions made within the specific area plus the awards and achievements of the scholars. The D-index threshold for listing leading scientists is set as an increment of 10 depending on the overall number of scholars projected for each discipline whilst making sure that the top 1% of best scientists are considered into the list. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.

Other verification methods
As our leading mission is to guarantee that only actual scientists are included in our ranking we are aware that numbers are never supposed to be an absolute means to evaluate the output of scholars. This is why we manually check every profile and cross-correlate it against publications in a wide range of trustworthy sources. While it’s not a metric impacting a researcher’s position in our ranking, the amount of documents published in major journals and conference proceedings should constitute a credible secondary implication of their contribution to research in a given field of study. Position in the ranking is determined by every researcher’s D-index using data compiled from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this type accessible to the scientific community. A comprehensive definition of our research policy can be found on our methodology page.

Our goal
Our mission is to inspire scholars, businessmen and decision-makers worldwide to explore where prominent experts are heading and to provide an opportunity for the whole research community to discover who the leading experts in specific disciplines, in various countries, or even within research institutions are.
