Scope and Policy

The journal aims mainly to publish researches in the Agricultural, Food, and Biological Sciences fields and Agribusiness. Papers in areas such as Exact, Earth, and other sciences are also welcome, as long as they are closely related to the context of agriculture.

Each manuscript is initially reviewed by the Editor, or Associate Editor, responsible for its respective field of knowledge, who will send an e-mail to the correspondent authors, acknowledging its receipt and generating a protocol number. This editorial review process can only begin if the manuscript obeys all the established norms. Otherwise, papers may be returned for corrections. So, in order to make the editorial process work faster, it is recommended that authors pay close attention to PAT's Instructions to Authors, before submitting their manuscripts.

Papers in accordance with the Instructions to Authors section will be analyzed by the Editorial Board, which will decide if the editorial process will continue or not. For that, the structure of the work will be examined, as well as its degree of interest to potential readers and the fields of knowledge it covers. Manuscripts that do not adhere to its editorial policy will be returned to authors, even before going through a technical-scientific analysis. Refused papers can be re-structured and submitted again. For every paper returned, the Editorial Board will justify exactly why it was not accepted.

Papers approved by the Editorial Board will have their scientific value assessed by two or three peer reviewers specialized in the subject, here named ad hoc consultants or referees. Authors' identities will not be revealed to peer reviewers and vice versa. These referees are chosen by the Editor or the Editorial Board, among recognized researchers in the specific area of each paper, preferably those not affiliated with the authors' institutions.

After analyzing the manuscript, each referee can choose one of the following options: i) Recommended with mandatory changes/corrections; ii) Recommended; or iii) Not recommended. In his/her report, or in the manuscript itself, the reviewer has total freedom to suggest changes, corrections, omit or add text and sections, to point out ambiguous, redundant, incoherent descriptions, inappropriate use of terminology or to request more detailed explanations. The PAT Editorial Board always encourages its reviewers to provide constructive criticism, concerning the analyzed papers. Thus, reviewers are requested to maintain a respectful tone in their observations, criticisms, and suggestions. They are also requested, with respect to authors and their unpublished scientific discoveries, to give a feedback within four weeks, or other deadline accorded with the Editors.

In order to preserve credibility and, at the same time, avoid any embarrassment, the PAT Editorial Board requests that referees, before beginning their analysis of a manuscript, consider the possibility of a conflict of interest. This may include, for example, a regular research collaboration with the possible authors (e.g.: publications), an adviser/advisee relationship; a commercial interest in the publication; family ties; involvement in the study; or any impediment to an unbiased evaluation. In this case, the referee is requested to return the manuscript to the Editor immediately, expressing the impossibility of analyzing it.

The text accepted by the Editorial Board also goes through language proofreading, covering spelling, grammar, and style. So, in order to make the editorial process proceed faster, it is strongly recommended that the authors have their texts checked before submission. A well-structured, harmonious, clear, concise, cohesive, precise, impersonal, and stylistically correct text is part of what PAT and its authors owe their readers and, above all, Science.

The decision of accepting or not a paper for publishing is based, fundamentally, in the recommendations made by the peer reviewer system. Complete copies of all reports, with the referees' identities omitted, will be sent to the correspondent authors. The Editorial Board understands that authors have the right to know how their paper was welcome by the scientific community, even during the editorial process. If the manuscript is submitted to only two referees, and one is favorable to publish it, while the other is not, then a third reviewer is invited to analyze it. If the majority of the reports are not favorable, the paper will be returned to authors, and they are generally encouraged to submit it again, in an improved version. However, before restarting the process, it is recommended that authors make certain their papers will go through a careful revision process, paying special attention to the editorial and technical suggestions.

If there is a predominance of favorable reports, the decision is for publishing the paper. However, that will only happen provided the editorial or technical recommendations be accepted or properly justified. A manuscript is rarely accepted without recommendations for improvement. Thus, it is important to authors to understand that requests for changes, nearly always, can improve the quality of their work, and that this kind of request is usual in high quality periodicals. For that reason, they should not take referees' comments, or even editors' corrections, personally. But if they disagree with any of them, they should prepare a written justification, scientifically based, to be sent to the Editor, along with the revised version. That will happen within the deadline agreed with the editors, that is, between thirty and sixty days, according to the level of adjustments to be made. Otherwise, the paper will be discarded. If there is any kind of justification, it will be analyzed by editors, which may send them to the respective referees.

After the analysis of the revised version, if the editorial and content suggestions have been properly incorporated or contested, the paper is definitely accepted for publishing and enters the editorial phase. Otherwise, it will be returned to authors for a new revision. Once more, the PAT Editorial Board assures authors the right to disagree with the suggestions presented. However, justifications without a solid technical and scientific basis will be rejected.

In the journal editorial process, the Editor may carry out small changes in the authors' texts to speed up the publication process. However, before making them available on-line, a copy is sent to authors, for proofreading. In this phase, major changes can no longer be incorporated. It is, thus, recommended that authors carefully read their texts, highlighting errors and corrections to be made. This revision must be completed and returned to the Editor, within five working days.


Form and preparation of manuscripts

The journal publishes Scientific and Review Articles related to the development of agriculture. The submission of Research Notes is not accepted and Review Articles are only published at the request of the Editorial Board.

Submissions are free of charge and made only on-line, through the website or All authors must register on the system and express, through the correspondent author, their agreement concerning the submission, editorial policy, and norms for publication in the PAT journal. For that, all authors must sign a document which must be submitted as a supplementary file (.pdf version) by the correspondent author (if authors live in different cities, more than one document can be submitted as a supplementary file by the correspondent author).

The PAT Journal recommends a maximum of 5 (five) authors per article. For more than that, a detailed description of each author's contribution must be sent to the Editorial Board (remember that, sometimes, the "Acknowledgements" section is more appropriate than authorship).

While submitting a manuscript, the correspondent author must also attest, in the name of all authors, the originality of the paper, that it is not being submitted simultaneously to other periodicals, and that they are in accordance with the format required for files, as well as with the copyright policies which will be applied if the manuscript is published. For researches dealing directly with animals or human beings as their main focus, a previous approval from an Ethics in Research Committee should be presented. For field experiments, it is necessary to present data from a minimum of two production cycles or two years of evaluation. Moreover, the author must enter the called metadata (information about the authors and the paper, such as title, abstract, key-words - in Portuguese and English), and transfer the files with the manuscript and supplementary files.

Manuscripts may be written in Portuguese or English, but will only be published in English.

Submissions may contain up to 18 pages. The text must be written using Microsoft Word for Windows (maximum size of 2MB, .doc version), A-4 paper size (210 x 297 mm), with 2.5 cm margins, single column, double spaced. The font should be Times New Roman, 12 points. Underlining and bold characters should be avoided, and all pages must be numbered. Manuscripts submitted to PAT must also obey the following specifications:

1. Scientific Articles must be organized in the following order: title (20 words maximum); abstract (up to 250 words); key-words (three words minimum, five words maximum, separated by a semicolon); title, abstract, and key-words in Portuguese; Introduction; Material and Methods; Results and Discussion; Conclusions; Acknowledgements (if necessary, in a single paragraph); and References. Acknowledgements and information related to the title of papers, as well as the authors' names, along with their respective affiliation, address and e-mail address, detailed in numbered footnotes, must only be inserted in the final corrected version of the manuscript, after it is definitively accepted for publishing.

2. The citations must use the "author-year" system. Only the first letter of the author's last name should be capitalized, and the author and year are separated by a single empty space. E.g.: (Gravena 1984, Zucchi 1985). The "&" symbol is used for two authors, and "et al." for three or more. E.g.: (Gravena & Zucchi 1987, Zucchi et al. 1988). If the author is mentioned directly in the text, just the year comes inside parenthesis. Secondary citations should be avoided, as well as the following sources:  article in a preliminary version (in press or preprint) or from a serial publication that is not peer-reviewed; summary of a paper presented in a scientific event; oral communication; information from poster sessions or panel discussions at a scientific event; private communications of unpublished documents; e-mails; or private sites on the Internet.

3. References must be arranged by listing authors' last name in alphabetical order, according to the NBR 6023:2002 norm, written by the Associação Brasileira de Normas Técnicas (ABNT). Italics must be used to highlight titles and periodical titles cited in full.

4. Tables and figures must be identified by Arabic numerals and always be referred in the text by these numbers. Tables must be drawn in black and white, using single lines, 0.5 point thickness (Microsoft Word for Windows standard), and their footnotes must be numbered. Terms such as "the table above" or "the figure below" must not be used. Figures should be presented with a minimum resolution of 300 dpi.

5. The Board of Editors recommends that authors always take a look at the articles recently published by PAT ( or, in order to solve doubts about these instructions.

6. Authors will not be paid for published articles and must waive their copyright in favor of the PAT journal. On the other hand, authors are solely responsible for the content of those articles, even if the Editor holds the right to adjust them to the norms of the journal. Authors are allowed to publish their articles simultaneously in their institutional repositories, as soon as the original publication at the PAT journal is mentioned.
