Authorship

Authorship gives credit, assigns responsibility, and implies academic, social, and financial accountability for the published work. Those who substantially contributed to a paper are credited as authors, understand, and take on their roles and responsibilities, and are held accountable for published research.

The journal’s definition of authorship is based on the ICMJE’s recommendation. The ICMJE recommends that authorship be based on the following 4 criteria:

• Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
• Drafting the work or revising it critically for important intellectual content; AND
• Final approval of the version to be published; AND
• Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Those who met all four criteria are identified as authors. In addition, responsibilities of co-authors for specific aspects of the work must be indicated. Please see the "Authorship information" section for details on how to indicate these responsibilities in the manuscript.

If the manuscript is authored by a large group or a consortium, all the members should meet all four authorship criteria. The corresponding author(s) must specify the group name and group members in line with the disclosure agreements.

For more information on how to acknowledge non-author contributors, equal contributors and corresponding author and other acknowledgements, please see the following sections and “Author Information” section.

Non-Author Contributions

Those who do not meet all the above-mentioned criteria are not qualified as authors, however, those who met at least one of the criteria should be acknowledged as non-author contributor and their contribution should be specified in the “Authors and Affiliations” section of the article. For more information on non-author contributions, please see: https://credit.niso.org/. Non-author contributions do not include but are not limited to the administrative support, general supervision, acquisition of funding, technical editing, language editing and proofreading. Non-author contributions should be specified and indicated in the title page on submission.

Equal Contributions

Authorship status and authors who contributed to the work equally should be indicated when submitting and publishing multi-author articles. JAS adopts the definitions of CreDIT and ICMJE for equal contribution. Accordingly, authorship status and equal contributions are defined as follows:

• Equal contribution: The authors contributed equally to the research.
• First authorship: The authors share first authorship.
• Equal contribution and first authorship: The authors contributed equally to the research and share first authorship.

Corresponding Author

The corresponding author is the designated author handling all correspondence with the journal, from submission to publication processes, on behalf of the authors. The corresponding author is responsible for complying with the journal's administrative requirements, providing the necessary information and documents, including authorship details, contact details, ethics committee approval, registration documents, payment of the EPC and APC, and signing publication agreements.

Article Types

JAS publishes original research articles and invited reviews only. The journal invites original research papers containing new insight into any aspect of the Agricultural Sciences that are not published or not being considered for publication elsewhere.

Preliminary, confirmatory or inconclusive research, case and local studies and works presenting new records and identification/taxonomy will not be evaluated.

Bibliometric reviews will not be evaluated.
