Scope and editorial policy

 

Brazilian Journal of Agricultural Research (PAB) is a monthly journal, edited by Brazilian Agricultural Research Corporation, Embrapa, which publishes English original scientific papers on subjects related to the agronomic area. The main format for papers is Articles but PAB also publishes Scientific Notes, and Review Manuscripts by invitation.

 

 

Form and preparation of manuscripts

 

Analysis of the manuscripts
The Editorial Board performs an analysis, before submitting the manuscripts to the referees. This analysis considers aspects such as scope, preparation of articles according to the journal's instructions, originality of the objectives, style of the composition, theoretical basis, an updated literature review, consistent and accurate methodology, results containing useful contributions, discussion of the observed facts in relation to the facts described in the literature, quality of tables and figures, and originality and consistency of the conclusions. After using these criteria, rejected papers will be returned to authors, and accepted ones will be submitted to the technical referees' analysis.

Form and preparation of manuscripts
Papers submitted to PAB must be original, not simultaneously submitted to or previously published in any other scientific or technical journal. Data previously published in abstracts containing more than 250 words must not be included in the paper.

Scientific Articles, Scientific Notes, and Review Articles (this last one only by the Editor's invitation) are the formats accepted by PAB.

Papers published are grouped in technical areas according to their main subject. The major technical areas are Entomology, Plant Physiology, Plant Pathology, Crop Science, Pomology, Genetics, Microbiology, Mineral Nutrition, Soil Science, and Animal Science.

Originals - The text should be typed in the Microsoft Word, double spaced, using Times New Roman font 12, paper A4 format, and with 2.5 cm margins, and have numbered pages and lines.

Cover letter
Upload your cover letter, which must be written in English, in a separate file in the designated area in the submission page. The cover letter should be used to certify that your manuscript is original and that it has not been submitted, accepted for publication, nor published in another journal or elsewhere in its final form, in printed or in electronic format.

Citations
References of summaries, documents in the press, or of any other source, whose data have not been published yet will not be accepted.

Self-quotations should be avoided.

They must be normalized according to the ABNT current guidelines.

Citations written in brackets

With just one author: surname written with the first letter capitalized, followed by a comma and the year of publication.

Two authors: surnames written with the first letter capitalized, divided by an ampersand (&), followed by comma and year of publication.

More than two authors: surname of the first author written in upper and lowercase, followed by the expression et al., in a normal font, comma and year of publication.

More than one work: they must follow a chronological order, and, after that, an alphabetical order of authors, and must be divided by semicolon.

More than one work by the same authors: do not repeat the name of the authors; commas divide the years of publication.

Citation of citation: surname of the author and year of publication of the original document, followed by the expression "cited by", as well as the citation of the work regarded.

Citation of citation must be avoided because there is a chance of misinterpretation; if it is essential, only the regarded work must comprise the references.

Citations out of brackets

With name of authors included in the sentence: they follow the previous guidelines, with the years of publication in brackets; they are divided by commas.

Formulas, expressions, and mathematical expressions
They must begin on the left margin of the page in a standard size of Times New Roman font.

They must not be in italics or in bold. Exceptions to the use of italics would be formula symbols conventionally written in italics.

Tables
Tables must be sequentially numbered, with Arabic numerals, and presented in separated sheets,

at the end of the text, after the references.

Tables should be self-explanatory, without the necessity to return to the text to understand them.

Essential elements: titles, headings, grid (columns and rows/lines) and column indicating treatments and variables.

Complementary elements: footnotes and bibliographical source.

The title, followed by a period, must come after the word Table, in bold, numbered sequentially in Arabic numerals. It must be clear, brief and comprehensive; it must include the species name (general or scientific) as well as the dependent variables.

In the headings, the names of the variables must be written in full; if this is not possible, explain the meaning of the abbreviations in the title or footnotes of the table.

Measure units of all variables must be presented using the International System of Units.

The columns of the data, numerical values must be aligned by the last numeral.

No table cell (crossings between lines and columns) may be empty. The lack of numerical data should be represented by a hyphen (-), followed by an explanation footnote. To indicate the minimum significant difference, lowercase or uppercase letters are used in the columns or in the lines, at the right of the data, with indication in the footnote of the test and probability used.

In order to separate headings from titles and from the table, use horizontal borders; use them also on the base of the table to separate the content from the complementary elements. Additional horizontal borders may be used inside the headings and tables; do not use vertical borders.

Tables should be assembled in Word files, using the menu Table; do not introduce spaces using the space bar of the keyboard, but the indentation on the menu format paragraph.

Table footnotes

Source notes: they indicate the origin of data on the table; sources must be in the references.

Indication notes: specific pieces of information about parts of the table, in order to form an opinion about the data. They are indicated in Arabic numerals, superscripted, in brackets, on the right of the word or number, on the title, on the headings, on the table, or on the column. They are continuous, without changing lines, separated by a period.

To indicate significance, the indications ns (nonsignificant); * and ** (significant at 5 and 1% probability, respectively) will be used.

Figures
Charts, graphs, drawings, maps and photographs will be considered figures to illustrate the texts.

They should only accompany the text when necessary to explain the described facts.

The title of the figure, without bold, must come after the word Figure, the number in Arabic numerals, and the period, in bold.

Figures should be self-explanatory, without the necessity to return to the text to understand them.

Legends (key to the adopted conventions) must be included in the figure, in the title, or between the figure and the title.

On the graphs, the indications of the axes X and Y must have initials in uppercase, and must be followed by the units in brackets.

After the figure title, non-original figures must include the source from which they were taken; sources must be in the references.

Copyright to the author of photographs is mandatory, as well as the copyright to the authors of drawings and graphs, which have required creative action in their construction.

To standardize units, font (Times New Roman) and size of letters in all figures.

Dots of curves must be represented by contrasting markers, such as: circles, squares, triangles or diamonds (full or empty).

Numbers that stand for the measures and respective signs must be out of the quadrant.

Curves must be identified in the figure, avoiding excess information that interferes with the understanding of the graphs.

Figures can not present data included in tables.

They must be organized in such a way as to present the necessary quality for good reproduction and measure 8.5 or 17.5 cm width.

The figures must be saved in Word, Excel, or Corel Draw, in order to make editing and corrections possible.

Use borders with, at least, ¾ width.

In the case of a graph of bars and columns, use a scale of proportional gray (e.g.: 0%, 25%, 50%, 75% and 100% for five variables).

Do not use bold in figures.

Photographs must have a resolution of, at least, 300 dpi and be saved in TIF files, separated from text files.

Avoid using colours in the figures; photographs, however, may be coloured.

Scientific Notes
Scientific notes are brief communications, which justify immediate publication, due to the fact that the finding is original and important, but the content is still not enough to constitute a complete scientific article.

Presentation of Scientific Notes

The organization of a scientific note must be the following: Title, authorship (with respective indication to authors' address), Abstract, Index terms, the text itself (including introduction, materials and methods, results and discussion, as well as conclusion, without division), references, tables and figures.

The guidelines to the presentation of a scientific note are the same as for a scientific article, except in the following items:

The abstract must not exceed 100 words.

The note must not be longer than eight pages, including tables and figures.

It may have up to 15 references.

It may have, at most, two illustrations (tables and figures).

Further information
There are no charges for publication.

Manuscripts accepted for publication are double reviewed by experts.

The editor and the referees have the right to request changes in the articles and to decide about their publication.

Opinions and concepts developed in the manuscript are of the authors' exclusive responsibility.

The accepted articles cannot be reproduced, even partially, without the expressed consent of the editor of PAB.
