The 2nd edition of Research.com ranking of the best researchers in the
field of Plant Science and Agronomy relies os data
combined from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which only includes
publications and citation metrics for an examined discipline.
The focus of our Plant Science and Agronomy research
Research.com’s best researchers ranking is a credible account of leading scientists from the area of Plant Science and Agronomy, established by means of a detailed analysis of 166,880 scholars determined from various bibliometric data sources. For the area of Plant Science and Agronomy, over 5065 scientists were analysed.
What is D-index acceptance threshold for Plant Science and Agronomy
The D-index threshold for including a scholar to be evaluated is set to 30 if most of their publications are in the area of Plant Science and Agronomy. The approval requirements for researchers to be considered into the ranking of top researchers are based on the D-index, ratio of the publications made within the selected area plus the awards and achievements of the scholars. The D-index threshold for listing top scientists is set as an increment of 10 depending on the overall number of scholars projected for each scientific field whilst ensuring that the top 1% of leading scientists are added into the list. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification methods
Because our primary goal is to guarantee that only credible scientists are mentioned in the ranking we realize that numbers are never supposed to be a full tool to assess the output of scientists. For that reason we manually inspect each profile and cross-correlate it against publications in a wide range of trustworthy sources. Although it’s not a factor contributing to a researcher’s position in Research.com ranking, the quantity of documents published in prominent journals and conference proceedings should constitute a reliable secondary signal of their contribution to research in a specific discipline. Position in the ranking is based on each scientist’s D-index according to information collected from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this kind accessible to the scientific community. A detailed definition of our research procedures can be found on our methodology page.
Our goal is to motivate scholars, entrepreneurs and administrative bodies worldwide to examine where leading experts are heading and to provide an opportunity for the entire scientific community to get to know who the leading experts in specific disciplines, in different countries, or even within research institutions are.
