All articles submitted to the Journal undergo a blind peer-review process. Each article on submission is reviewed for relevance to the scope of the Journal by the Editor-in-Chief. Articles that do not meet the basic criteria are rejected at this stage and authors promptly informed. Articles that meet basic requirements are initially reviewed by at least two reviewers. The recommendation of the reviewers informs the decision of the Editorial Board to accept on the conditions that the concerns raised by the reviewers are addressed (the article is back to the authors to address the reviewers concerns) or to reject. Where there is a notable disagreement between the reports of the two initial reviewers, a third reviewer may be consulted. The Nigerian Agricultural Journal (NAJ) aim is to have a first decision to the authors by at least 6 weeks after submission.

Selecting Reviewers

NAJ continually builds a data base of potential reviewers. In sourcing and assigning reviewers for each article, attention is given to the keywords of the article, citations, membership of the association and similar networks with works and specialization on the issues addressed by the article. Effort is made not to select a reviewer from the same institution as the author.

Publication Ethics

Articles published in the Nigerian Agricultural Journal (NAJ) must be relevant to agricultural works and should not have been published or under consideration for publication elsewhere. Authors submitting articles to NAJ are required to do a declaration that implies that the work described has not been published previously/elsewhere, not under consideration for publication elsewhere, its publication is approved by all authors and/ or authorities where the work was carried out, and if accepted, will not be published elsewhere including electronically. The Journal holds Authors responsible for keeping to the highest ethics in publishing, particularly with fabrication, falsification and plagiarism. Authors are expected to do plagiarism test and indicate programme used for this.   Also, Authors should note that their article will be screened for plagiarism (using the software “Plagiarism Checker”) for confirmation at any point in the review process. Complaints on issues of ethics should be reported to the Editor-in-Chief. The Editorial board will make final decision on such complaints.

Conflict of Interest

Conflict of interest (COI) in the Journal publication process occurs when influence other than science result in an article being either rejected or published misleads the reader. Conflict of interest can arise in the development, review and publication of an article, when there is a strong positive or negative bias toward the authors on the part of the reviewers or the editor handling the manuscript. COI involves using your position as an author, editor, or reviewer to promote your interests (business or financial), or those of your external relationships (family, friends or employers). When advancing outside interests is more important to a reviewer than advancing the aims of NAJ, that reviewer stands in a conflict of interest. The NAJ policy is that COI must be taken into considerations for each step of the development, evaluation and publication process. Authors must include a declaration at the beginning of the manuscript in which they must either state that no conflict of interest exists. Editors and reviewers must give full disclosure of COI on first contact with a NAJ manuscript to the Editor-in-Chief that no conflict of interest exists or describe the nature of any potential conflict.
