INSTRUCTIONS TO AUTHORS

Scope and policy

The Chilean Journal of Agricultural & Animal Sciences is a double-blind peer-reviewed scientific journal that publishes research works in all areas of agronomy, agricultural engineering and veterinary medicine.

The journal was formerly known Agro-Ciencia. In 2013 Vol. 29 N° 2 it changed its name to Chilean Journal of Agricultural & Animal Sciences, also resulting in changes in its ISSN numbers. The journal is published tri-annually (May, August and December) since 2014.

The journal welcomes original articles, written in Spanish or English, which have not been published or submitted simultaneously to another journal, or published in full in conference proceedings. Articles are subject to a double-blind peer review process, i.e. reviewers do not know the names of the authors and the authors do not know the names of the reviewers. Authors may suggest names of potential reviewers, but the editor reserves the right to select other reviewers; the process will remain anonymous. There are no fees for publication.

In case of doubts on the acceptability of submitted manuscripts, or upon author's request, the editor will seek input from one or more additional reviewers. However, once final decision is made, appeals will not be considered.

The Chilean Journal of Agricultural & Animal Sciences subscribes to open access principles (Open Access). All articles published in the journal are licensed under the Creative Commons Attribution-Non Commercial 4.0 International license. Information/data contained in the articles published in the journal can be reproduced as long as citation is provided.

Copyright: Accepted articles become the permanent property of the Chilean Journal of Agricultural & Animal Sciences and may be reproduced, in whole or in part, only if information is properly cited.

Results and Discussion sections can be separate or combined.

If in doubt, please refer to a recent edition of the journal for guidance on style and presentation. Authors can also refer a recent issue of the Agronomy Journal, Soil Science Journal, or Crop Science Journal, which provide detailed instructions for article submission (both format and style). Please visit https://www.agronomy.org/publications/style or the Agronomy Journal’s website at https://www.agronomy.org/publications/aj.

1. TITLE

The title should reflect the content of the article. It should not exceed 18 words and be clear and concise. Please avoid starting the title with words like: Effect of, Influence of, etc. Use the common name of plants, insects or pathogens, followed by the scientific name in parentheses, using italicized and lowercase letters. Only the first letter of the genus name and author should be capitalized.

The main title must be written in the same language as the manuscript.  It should be capitalized, centered and bold print, and followed by a translation to English or Spanish as appropriate, observing the same format. Authors’ full names must be typed below the title, identifying affiliations (the institution to which each one of the authors belongs) by superscript numbers, and indicating postal address, city and country, and email address. The corresponding author should be indicated with an asterisk. If in doubt, please refer to recent issue of the journal. Provide a short descriptive title of no more than 10 words that will appear at the top of every odd page of the journal.

2. SUMMARY

The Summary is the most widely read part of a scientific article. It provides the readers with a condensed overview, encouraging them to read through the full text of the article. The summary should not exceed 250 words on a single paragraph and it should include the following five elements: a brief introductory phrase describing the relevance of the study, research objectives, materials and methods, principal results and main conclusions. Do not include references or formulas.

Up to six key words should be given below the Summary. Key words facilitate retrieval of articles by search engines, web directories and indexes. The selected key words should not repeat words given in the title since this is covered by most search engines. The aim is to assist potential readers to find the article by specifically describing its subject matter, including aspects of methodology or the theoretical framework.

3. ABSTRACT

The abstract should be written in bold. It corresponds to the English translation of the Summary and it is followed by the key words.

4. INTRODUCTION

The introduction gives readers a heads up as to type of study conducted. It establishes the context and significance of the research conducted by summarizing current understanding and background information about the topic, citing current publications that do not exceed 10 years from publication; older citations may be accepted if justified. Depending on the type of study, the introduction should also include the hypothesis. The study objective(s) should be clearly stated at the end of this section.

Authors should only cite the most recent and important publications in this section. Other references should be included in the Results and Discussion. Writing should be clear, precise and concise, in accordance with the standards of the language in which the article is written.

5. MATERIALS AND METHODS

The Materials and Methods section gives a detailed account of the procedure that was followed to do the experiment, including a complete description of the materials so that another researcher can replicate the experiment and get the same results. It should include the year and season when the experiment was conducted, as well as the geographic coordinates of all sites mentioned in the work. The description of materials should be concise. If techniques or procedures used have been previously published, please provide a summary and references. Major modifications of an original procedure should be clearly indicated and described in this section.

At first mention, equipment and instruments used in the experimental work must be identified by their common name; between parentheses include trademark, model, manufacturer city, state and country. Give the technical or generic name or provide the active ingredient of chemical products and dosage used; at first mention you can include trademark in parentheses.

The experimental design and statistical analysis should be explained in this section, providing references and including them in the appropriate section. Field experiments, sensitive to interactions and environment changes, should usually be repeated as to time or space, or both, to ensure representative results.

6. RESULTS AND DISCUSSION

The Results and Discussion sections can be combined into a single section or be separated into two sections. Authors are encouraged to provide a single sections. Tables and figures must be numbered in sequence, in the same order as they are mentioned in the text. Avoid repeating information contained in tables or figures. Tables and figures should be self-explanatory so that readers do not have to refer to other parts of the text to understand them. Table or figure titles should be brief but sufficiently detailed to explain the data included, identifying scientific names of the organisms mentioned. Footnotes should also be provided, including abbreviations, units, etc., even if the information is provided in the text.

The discussion section should include a brief statement of the principal findings based on statistical analysis, a discussion of the findings in light of other published work dealing with the same or closely related subjects, and a statement of the possible significance of the work.

7. CONCLUSIONS

The Conclusions section should include the major conclusions based on the research objectives. Other comments should be included in the Results and Discussion sections. Do not number the conclusions.

8. ACKNOWLEDGEMENTS

If required, authors may include an Acknowledgements section. This section allows authors space to recognize and express appreciation to those who have contributed to the study by providing general advice or guidance, technical help or financial support. Please add this section before Literature Cited section.

9. LITERATURE CITED

Every cited publication in the work must be included in this section. Make sure that you list only the references cited. References must be listed in alphabetical order according to the first author’s last name. When the same first author appears in multiple references, arrange them alphabetically by the second author’s last name, refer to the subsequent author’s last name if necessary. If your list of references includes authors with the same last name, arrange them in chronological order. Cite the first author by his/her last name followed by his/her first initial, but co-authors should be cited with initials followed by last name. Names of authors should be separated by commas, including the last one, which will be preceded by the words ‘y’, ‘and’, ‘et’, ‘und’, etc., depending on the language of the citation. References must be presented in their original language. For works with more than six authors, indicate the six last names followed by the abbreviation “et al.” (not italicized).

In-text citations include the author’s last name and year. These should appear in chronological order and should be separated by a semicolon (;). When two authors have written the source, include both of their last names. If a work has more than two authors, list only the first author’s last name followed by “et al.” (not italicized). If multiple works published by the same author(s) in the same year are mentioned, add a lowercase letter immediately after the year, with no space: letter ‘a’ is assigned to the first citation, letter ‘b’ to the second, and so on. Citations by the same author and different publication dates are separated by a semicolon (;).

Cited literature should correspond to articles published in mainstream scientific journals in the last 10 years. Articles from either printed or electronic journals can be cited. Authors are encouraged to do not include citations of texts, theses and abstracts presented at scientific conferences. Citations of papers published in journals without editorial board or peer review, faculty publications or personal web sites are not accepted.

Format for citations in provided later in this document.

10. TABLES

Tables should be self-explanatory, stand alone, complete and descriptive by itself, so that the reader does not need to refer to the text to understand the information provided. Please create tables in Word using the Insert Table function.  Tables should be numbered in sequence with Arabic numerals. All sections of tables should be 1.5 spaced. Table titles must be brief but sufficiently detailed to explain the data included. Use table notes (footnotes) to show significance analysis and explain abbreviations or symbols.  Please indicate scientific names when appropriate. Translate table titles into English.

Column and row headings should reflect the type of data shown. If headings require abbreviations, include their definition in the table footnotes. Indicate units of measurement in each case using the International System of Units (SI) only. Numbers ​​must be aligned on the decimal point. All numbers ​​must have the same number of decimal places.

11. FIGURES

Each figure should stand alone, complete and descriptive by itself so that the reader does not need to refer to the text to understand the information provided. Figure titles should be descriptive but sufficiently detailed to explain the data include.  All abbreviations should be defined in the footnotes. Legends within figures should be clear and include the SI units of measurement.

Number figures in the order they are cited in the text with Arabic numerals (graphs, drawings and photographs). Cite figures as Fig 1, Fig 2, Figs. 1-5, etc. Do not draw a box around graphs. Submit drawings and photographs at high-resolution, indicating the scale. All figure elements, including letters, numbers, and symbols, must be legible at their final size. In general, authors should make figures large enough to stand reduction.

12. SCIENTIFIC NAMES

Complete scientific names (genus, species and nomenclatural authority) should be given when organisms are first mentioned in the title, abstract or text. Please also include scientific names in tables and figures.

Names of genus and species should be italicized. The authority should be written in normal type font. For example: rice (Oryza sativa L.). After first mention in the text, scientific names can be abbreviated, indicating the initial of the genus and species (e.g.: O. sativa). If there are several genus names with the same initial, names should be spelled out rather than abbreviated. Do not use abbreviation for genus name at the beginning of a sentence. Genus name alone should be italicized.

13. ABBREVIATIONS

All abbreviations should be explained or defined at their first mention in the text, table or figure. Abbreviations should be written out in full at the first citation, followed by the abbreviation in parentheses. Subsequently, use the abbreviation only. All abbreviations and acronyms are used without a period.

14. METRIC SYSTEM

All measurements should be expressed in SI units and abbreviated (without periods). Use standard abbreviations for SI units (lowercase, e.g. kg, ha, g, mm), but use capital L for the abbreviation of liter to avoid confusion of the lowercase (l) with unity. When using exponential notation, allow only one space to indicate exponent or power, e.g. kg ha-1; mg kg-1; mL L-1.

Use commas to separate decimals in Spanish; use dots (periods) to separate decimals in English.

15. CULTIVAR NAMES

The terms ‘cultivar’ and ‘variety’ are considered synonyms. These are abbreviated cv. or var., respectively. Authors are encouraged to use the term “cultivar” in order to avoid confusion with botanical “variety”. Cultivar names can be enclosed by single quotes not being necessary to repeat the term ‘cultivar’. For example, Triticum aestivum ‘Chifen’ equals to “Triticum aestivum cultivar Chifen”.

16. TRADE NAMES

The use of trade names should be avoided. Use common, technical or generic names or names of active ingredients. If included in the text, trade names should be given in parentheses with the trademark symbol ® following the first text reference.

GENERAL GUIDELINES FOR REFERENCES

References are an important part of a scientific article. These show that authors are familiar with the latest advances in the field and help to avoid plagiarism. Citations must be correct and complete, since data base organizations use them to calculate bibliometric indicators, such as impact factor, h-index, immediacy index, and others that nowadays play an important role in research evaluation. References should enable readers to trace the exact material used.

References should follow both format and specific punctuation rules, as indicated in the examples provided later in this document.

Cites of scientific articles must include: author (s), year, full or abbreviated journal title, followed by volume and page, separated by a colon (:). If case of journals that paginate per issue (with no pagination per volume), include Volume and Issue in parentheses. Do not place a space before and after the colon (:). The doi number is included al the end of each reference.

In case of books, citations must include author(s), year, full title, edition number (except the first), publishing house or responsible institution, city, state (if applicable) and country. Note that there are institutional/corporate authors. Do not confuse the printing company with the editorial or publishing company.

For book chapters, include: author(s), year, chapter title, and pages, and after the words “En” or “In” according to the cite language include the book citation.

Cites of references of proceedings of congresses must include: author(s), year, title of article and page of article, after the words “In” or “En”, according to the cite language, indicate editor(s), event or publication name, city, state (if applicable) and country, date of the event and finally publishing house or institution, city, state and country.

Electronic references must include author(s), year, full title, the uniform resource locator (URL) address and the date it was read or accessed in parentheses. In case of institutions, provide the acronym or full name of the corporate author (s).
