INSTRUCTIONS TO AUTHORS
Scope and policy
The CHILEAN JOURNAL OF AGRICULTURAL RESEARCH, formerly Agricultura Técnica (Chile), is a scientific journal edited by the National Institute of Agricultural Research (INIA), and is published every quarter. At the same time, it is published in electronic format in three websites:(http://www.inia.cl/at/agritec.htm;https://scielo.conicyt.cl; http://www.biolione.org.br/at/) with free access to the full text, for a greater international visibility of the authors and the journal.
The CHILEAN JOURNAL OF AGRICULTURAL RESEARCH,
formerly Agricultura Técnica (Chile), publishes contributions of
researchers from Chile and abroad, from research institutions and universities,
in Spanish and preferably in English. From this year (2008) the journal
will publish all contributions in English, but in the web site http://www.inia.cl/at/agritec.htm
will publish the English version and the Spanish version of those papers
received in this language. The contributions are anonymously peer reviewed
to ensure reviewer impartiality. The journal has been improving the scientific
quality of the articles published, thanks to the contribution of the Editorial
Board and reviewers, all outstanding national and foreign researchers.
The Editorial Board decides on the acceptance or rejection of a paper
and appeals are not accepted.
Form and preparation of manuscripts
Articles should be original, with results that represent a real contribution to scientific knowledge, and should not be submitted simultaneously to other journals. Editing style should be clear, concise and fluid. The extension must not exceed 18 pages for the sections RESEARCHES, REVIEWS, and ACTUALITY, 10 pages for SCIENTIFIC NOTES, and 2 pages for BOOKS REVIEWS. The author could pay for extra pages provided the acceptance of the Editorial Committee. We accept articles that have been presented abridged in congress, symposia, etc., but this fact should be stated as a first page footnote.
Manuscripts can be submitted electronically, however, we strongly suggest authors to read a printed final version in order to evaluate the article format and style. If you decide to use conventional mailing, attach a diskette or CD copy. Use paper size letter 21.7 × 28.0 cm, Times New Roman font, letter size 11, 1.5 spaced, 2.5 cm margins, page and line numbered. Use Microsoft Word for text and tables and Excel for figures.
A manuscript well redacted, written carefully with attention to details, which follows rigorously these Instructions to Authors, allow a quick and expedite edition and reviewing process. Editors and specialized reviewers do their job ad honorem, and become very tedious to review a paper with a poor redaction and presentation. It is recommended to ask a specialty colleague to critically review the manuscript before submitting it. Authors can suggest the name of some specialists to be considered by the respective specialty editor as a reviewer, but the process is completely anonymous.
RESEARCHES. These are significant contributions to the advancement of scientific knowledge, experiments following standard experimental designs, statistical analysis and discussion of results supported by an up-to-date literature review.
REVIEWS. In this section we publish papers developing a relevant topic, strongly supported by relevant and updated national and foreign bibliography, according to the Chilean Journal of Agricultural Research editorial line and must be approved by the editorial board. They are reviewed according to the same norms of research articles.
SCIENTIFIC NOTES. These are brief presentations about various subjects, such as new cultivars reports, current research, species determination, method descriptions, etc. Title, footnotes, tables and figures are presented according to the Research article norms.
BOOKS REVIEW. Brief reviews of recent books, giving a general idea of the content, are accepted. Indicate name, institution and postal address of the review’s author.
One indicator of research quality is cited literature, which must include the most recent scientific papers about the subject published in mainstream journals. Current references must not exceed 10 years from publication. It is the author’s responsibility to present the references correctly and in full, based on these instructions. Verify that all text cites are included in Literature Cited and vice versa. Cites are presented in the same language of the paper being cited. They are listed alphabetically and must be presented according to this guide.
Literature Cited includes mainly papers published recently in prestigious mainstream scientific journals. Books about classic methods and postgraduate theses are also included. It can include, but restrictively, proceedings of congresses or scientific events which are available in the bibliographic research system, so that any interested reader can find them. Restricted circulation publications cannot be cited and should be avoided, but if you require doing so, this must be cited in the text as “personal communication”. It is not recommended to cite divulgation or extension magazines in a scientific paper.
List references alphabetically. For the first author,
cite last name and then the initial of the name; for co-authors use the
initial of name and then the last name, spelled out. Authors are separated
by a comma, including the last author. Pay attention to the use of comma
and periods; see examples ahead.
Cites of scientific journal papers must include: author(s), year, full title of article, abbreviated journal title, volume, and pages. Do not put a comma after the journal name, full or abbreviated. Any abbreviated word ends with period. Only the first word and proper names in the article title start with uppercase. Use abbreviated title accepted by the same journal, e.g., Agron. J. 98:243-249.
We strongly suggest do not cite magazines or extension publications, but if you do you must bear in mind that these publications usually paginate per issue; there is no pagination per volume, therefore you must mention Volume, Issue or supplement within brackets, a colon and then the pagination. Example: Magazine’s name 11(2):5-10. When the publication has no volume, include number and pagination, e.g., N° 59. p. 25-28.
In the case of books, citation include author(s) or editor(s), year, title, translator if any, specific pagination if just a part was consulted, edition number (except the first), publishing house or responsible institution, city, state and country. For book chapters include: author(s), year, chapter title, pages, after the Latin word In indicate book’s author(s) or editor(s), full title of book, edition number (except the first), publishing house, city, state, and country.
As publishing house we refer to editorial or publishing institution, such as McGraw-Hill, Cambridge, Editorial Universitaria, etc., or an organization as Institute of Agriculture Research (INIA), FAO, University of Chile, Iowa State University, USDA, etc.
References of proceedings of congresses, symposia, workshops, etc., are cited as follows: author(s), year, title of article or chapter, pages of article, after the Latin word “In”, indicate editor(s), event or publication name, city, state and country, date of the event and finally publishing house, city, state and country.
Graduate thesis should be cited as follows: author, year, title, pagination, grade obtained, university, faculty, city, state, and country. We suggest avoiding citing undergraduate thesis.
Manuscripts accepted for publication but still not published can be included in Literature Cited indicating “In press” after journal title. Cite accepted articles only.
Electronic references should contain the same elements as the printed publications, plus the uniform resource locator (URL) address, preceded by “Available at” or “Disponible en” and “Accessed” or “Leído” plus the date in parentheses, according to the cite language. Journals published electronically are cited in the same way as the printed versions, with volume and pages, but including also the URL and the date it was accessed or read.

Scientific names. At first mention of plants, insects, and pathogens, give the common name and in parenthesis the scientific name (in italics) and the authority, in the abstract or the text, in tables and figures. Afterward you can mention just the common name or the initial of the genus and the species of the scientific name, except when two or more names of genus share the initial, in this case spell them out to avoid confusion. Check nomenclature in a reliable source, such as the Germplasm Resources Information Network (GRIN) database (http://www.ars-grin.gov/~sbmljw/cgi-bin/tax_search.pl).
Chemical products. At the first mention of herbicides, insecticides, fertilizers, give the technical or generic name and dosage used, between parentheses include commercial name, dosage, manufacturer, city, state and country; thereafter use just the technical name.
Soils. At first mention, identify soils at the series and family level and include USDA Soil Taxonomy classification so as to make the paper more accessible to international readers.
Equipment and instruments. Equipment and instruments used in experimental work must be mentioned by their common name; between parentheses include trademark, model, manufacturer city, state and country.
Numbers from one to nine are spelled out, except when they include a unit or several numbers are mentioned. Example: “six irrigations”, “6, 9 and 12 irrigations”, “8 kg”. Decimals are indicated with a point in English and a comma in Spanish; add a zero before the decimal point or comma when the quantity is smaller than one. Thousands in Spanish are indicated with a point but in English we use a space.
For intervals of one or more years use the word “to” to separate numbers in the text; use hyphen to mention growing seasons (eg., Period 2002 to 2005; 1999-2000, 2000-2001 growing seasons).
Measurement units. Results should be expressed in units of the International System of Units (SI); if you use other units they should be in parentheses after the SI unit. It is suggested to use an exponential form instead of a slash, e.g., kg ha-1.
Abbreviations and symbols save space and time, but excessive use prevents understanding the text. Some widely used and known abbreviations such as SI units or chemical elements need not be defined. All abbreviations should be spelled out at their first mention, in abstract or in the text, tables and figures; afterwards use the abbreviation consistently. Avoid redefining widely known variables, as N for nitrogen, or DM for dry matter, and use this option for abbreviations proper of your article.
Use subscript for modifications, reserving superscript for power or table and figure footnotes, e.g., to name variables as leaf area, prefer Aleaf instead of ALEAF.
Use the 24-hour time system, with two digits for hours and two digits for minutes (e.g., 14:30 h instead of 2:30 p.m.).
In tables place a zero before the decimal point. Do not use more than three decimals. If there is not data for an individual entry insert a hyphen or an abbreviation and define it or explain it in a table footnote (e.g.: not significant).
Tables and figures style should be uniform, especially for units, dates and abbreviations. Footnotes are specified with superscript numbers, independently for each table or figure. The superscript preferred order is 1) title, 2) column heading, 3) row heading, and 4) table body.
Citing references in the text. When a reference has one or two authors, cite the last name of the author(s) and year; when the same author(s) has two references on different years, name them together in text (e.g., Huntington et al., 1988; 1990). When the reference has three or more authors, use the Latin expression “et al.” (abbreviation of et alli, meaning “and others”) and then include the year. For two or more articles using the same within-text citation, add a distinguishing letter (a, b, c, etc.) to the year in both text and Literature Cited. When two or more cites are included as a group in the text, they should be chronologically ordered. Several cites for a same year are alphabetically ordered.
Unpublished data, personal communications and reports not available to the public in the bibliographic system are not recommended for inclusion. If it is required to cite it, do so in the text between parentheses as “Personal communication”, including complete author’s name, year, and affiliation. If unpublished data belongs to the author indicate it as “unpublished data”.
Within-text citation of statistic software must include the reference between parentheses and the complete reference added in Literature Cited.
Avoid redundancy when indicating the statistical significance of differences (do not use “significance” in addition to probability). e.g., write “stearic acid concentration was higher (P < 0.05) in... than...”
Do not start a sentence with a number; spell it out and add the SI unit. Abbreviate SI units preceded by numbers (e.g., 7 kg, 32 d), except at the beginning of sentences.
Ordinal numbers from first to ninth are spelled out in the text, but can be abbreviated in tables. Abbreviate higher ordinal numbers (e.g., 12°, 32°).
Do not use hyphens to indicate inclusion (e.g., use 12 to 14 mg or week 3 and 4, instead 12-14 mg or week 3-4).
Place a space before and after most mathematical operators (the main exception is the solidus sign for division). Plus and minus signs have no space between sign and number when used to indicate positive or negative number.
Formulae for simple compounds (NaCl) are acceptable.
The first letter of trademarks should be uppercased, without ™ or
