Articles must have a logical structure, with the following sequence of sections:
Title (in Spanish and English)
Authors (including place of work and postal address)
Abstract (up to 200 words, approximately)
Resumen (Abstract in Spanish)
Palabras clave (Keywords in Spanish)Introduction Materials and methods
Results and discussion
Conclusions (only if deemed necessary)
Acknowledgements (if any)BibliographyThe titles of the sections must be placed in the centre of the page and the subheadings in the left margin.
In the text, mentions of authors must be made as follows:
(Sánchez, 1999) if there is only one author
(López y Araya, 2001) if there are two authors (texts in Spanish)
(Scott & Aldrich, 1998) if the book or article is in a language other than Spanish.
(Iglesias et al., 2000) in the case of three or more authors.
Where there is more than one citation these must be ordered chronologically. In the case of different works by the same author in the same year, these must be identified by an additional letter: (Sánchez, 1998 a,b). All transcripts must be in inverted commas, citing the author. Where personal correspondence is used, this must be cited in the text -indicating name and year- and not in the bibliography.
Full scientific names must be cited when they are first mentioned. For subsequent mentions the initial of the genus plus the species, without adding the class. If using the common name, this must be accompanied by the scientific name when first mentioned. All Latin words must be written in italics (e.g. et al, in vitro).
Chemical symbols may be used in the text (e.g. N for nitrogen, C for carbon). However common chemical formulas must not be used to replace words (e.g. water, not H2O). Abbreviations in common use may be used, such as ATP, DNA, RNA, etc.
When the text refers to numbers from zero to nine these must be spelled out (except when they are accompanied by units of measurement or the citation includes larger numbers (e.g. 3, 8 and 15 plots). Decimals take a comma when writing in Spanish, and a decimal point when writing in English.
Results of studies may be presented in tables and charts, which must be on separate pages, numbered independently and correlatively with Arabic numerals. Charts must fit the layout of the journal, hence their dimensions must be 7cm wide (equivalent to one column) or -only if necessary- 15cm (double column). The height must never be greater than 20cm. Charts will only be accepted in bmp, jpg and tif formats. Photographs should preferably be submitted on black and white gloss paper, and their base size should be 7cm, or 15cm if necessary, but no other sizes. Photographs will not be accepted if they do not have excellent definition or do not comply with the requisites given here. Colour photography or charts will only be included where these are essential.
In the bibliography only authors referenced in the text may be listed, ordered alphabetically by main author. When the author(s) is referenced several times, the name(s) must be repeated as many times as is necessary, ordering works in chronological order. All bibliographical citations must start with the surname and initials of the main author, followed by the initials and surnames of the co-authors.
Bibliographical references for periodicals (journals) must include the following information:
Year of publication (without parenthesis, in Arabic numerals)
Title of article
Name of periodical in which the article appeared
Volume and issue of periodical
E.g. Syers, R.; A.S. Vampbell and T.W. Walker, 1970. The contribution of organic carbon and clay to CIC in a chronosequence of sandy soils. Plant and Soil 33:104-121.
Bibliographical references for a book or pamphlet must include the following information:
Year of publication (without parentheses, in Arabic numerals)
Title Number of edition (if not the first)
Place of publication
Page number (to express pages consulted put p. before the number or pp. if it is more than one page, or afterwards if this is the total page numbers)
E.g. Wong, E.G., 1976. Biosynthesis of flavanoids, in Chemistry and biochemistry of plant pigments. TW Goodwined Academic Press, London, pp. 464-526.
Burrough, P.A., 1986. Principles of geographical information Systems for land resources assessment. Clarendon Press, Oxford. 194 pp.
Communications must contain title in Spanish and English, resumen, palabras clave, summary and key words. The article may not have a formally logical structure, but its text must include the sections requested. Acknowledgements (where relevant) and bibliography should go at the end.
Reviews by leading researchers in their specialization will be published, and these will be requested by AGRISCIENTIA. Alternatively, authors of potential reviews must contact the Scientific Director to suggest issues and approaches.
For queries on any of these matters, consult the most recent volume of AGRISCIENTIA or contact the journal by e-mail.
