The Latin American Potato Journal accepts original and unpublished articles of the following types:

 

1. Original full papers. Presents in detail the original research results. The structure generally used has the following essential parts: Introduction, Summary (Spanish or Portuguese and English), Materials and methods, Results and Discussion, and Conclusions.

2. Reflection article. Presents research results from an analytical, interpretative and critical perspective of the author, on a specific topic and using original sources.

3. Review article. Presents the result of an investigation where research results are analyzed, systematized and integrated, published or not, on a field in science or technology, in order to account for advances and development trends. It is characterized by presenting a careful bibliographic support.

4. Short communication. Document that must have less than 10 pages, with a maximum of three Tables/Figures. Short communications should inform the most relevant aspects of the chosen topic, should also serve to stimulate readers' concerns, raise questions and point out the most current lines of research on the subject. In general, the same instructions applied to the original articles will be followed, presenting a summary in English and Spanish (or Portuguese), keywords, Tables and Figures with the format described in the journal. The difference is that the body of the text is not divided into sections and the methods are briefly described.

 

The papers accepted by the Latin American Potato Journal will also be published in English in the website. Authors can inquire for the cost of translation services of their works into English offered by the Latin American Potato Journal or send it to any other translation services that the authors find suitable.

 

 

 

I. Form and preparation of manuscripts

Authors should follow the following instructions; items that do not comply with them will be returned without being evaluated. Manuscripts in digital format must be submitted in duplicate, on letter size paper (21.6 x 27.5 cm); written in double space, with margins of 3 cm and numbered both the pages and the lines. One copy must omit the author's details. Articles must be processed in Word for Windows or a compatible application, written in Times New Roman, font size 12.

The work should not exceed a maximum of 20 pages or 6500 words, including Figures, Tables and References. The language used must be clear and precise and the work must be written in third person. The past tense should be used for the Introduction, Materials and Methods and Results sections.

Tables and Figures (graphs, drawings, diagrams, flow charts, photos and maps) must be presented on separate sheets and with consecutive numbering (Table 1 or Figure 1). The limit for figures and tables is three for each category, with a total limit of five elements in short communications and ten elements in original articles. The legends of figures and tables must explain themselves and be concise. In case of exceeding the limit of figures and tables, these should be sent as supplementary information. Texts and tables must be presented in the MS-Word® word processor; the original Tables and frequency diagrams (bars and cake) must be provided in the manuscript file and also in its original MS-Excel® in annex; Other figures, such as photographs and drawings, can be sent in originals or scanned and sent in digital format (JPG), preferably with a resolution of 600 x 600 dpi (minimum 300 dpi). As a general rule, Tables and other Figures are only accepted in black and white; exceptionally color will be included in those used for the cover of the magazine and, if strictly necessary in the opinion of the editor. The text of the article, together with the respective (Figures) should be sent to the editor of the magazine.

Trade names and trademarks should be avoided in the body of the text (or mentioned in parentheses). Commercial products must be referred to by the technical name or the main ingredient (initial capital letter). Only internationally accepted abbreviations should be used. In the case that acronyms no well known are used, they must be written in full on the first time they are used, followed by the acronym in parentheses. All acronyms and abbreviations should be written without a semicolon after them. The metric decimal system should be used for all measurements and those abbreviations for common units of measurement: kilogram (kg), gram (g), milligram (mg), meter (m), etc. Avoid footnotes, except for information about authors of an article. Use a single font size.

The structure of the article must follow the accepted steps used by the Scientific Method, therefore:

 

1. Title. It should be brief but illustrative, not exceeding 15 words. This title should be translated into English and a short title should also be included for page headers. When including scientific names of plants or animals, they should be written in italics in lowercase, and only the first letter of the genus and the classifier in capital letters.

 

2. Authors. Full names should be included when accrediting the authors of any article. Authors should figure in agreement with the importance of their contribution to the research or preparation of the article. Authors should not be listed in alphabetical order, nor in terms of rank. Please clearly indicate the authors’ affiliations addresses, the institution and complete postal address (including email) should be marked with an asterisk and a footnote, identifying the corresponding author. The corresponding author is responsible for the final edition of the document, as well as for the final approval of the manuscript by all the co-authors. Authors should complete the excel table found here, which should be send together with the cover letter to the editor. This table includes the ORCID of the authors. If the authors do not count with ORCID, they should obitain one free of cost at the following link https://orcid.org/.

 

3. Summary in Spanish or Portuguese. This must be concise and contain information on the justification, objectives, methodology and concrete results of the investigation. You should indicate the main conclusions, emphasizing the achievements. It should not exceed 250 words, these should be written in a single paragraph.

 

4. Keywords in Spanish or Portuguese. There should be a list containing a maximum of five keywords of the article (different from those included in the title) that facilitate the use of modern computerized cataloging and information search systems. These words should be below the last line of the Summary, on the left margin of the text and with lowercase letters, separated by commas.

 

5. Summary in English. This should be a technical translation of the summary into the English language.

 

6. Keywords in English. There must be a faithful translation of the keywords into the English language.

 

7. Introduction. Describes the general purpose of the problem investigated, giving the necessary information with precision, referring only to the related literature considered indispensable to develop the topic, allowing the current state of it. It must clearly indicate the objective of the research hypothesis and its relation to other relevant works (it should not include extensive literature reviews). If scientific names are included, these must be accompanied by their vernacular name as well as the abbreviation of the classifier in the first mention within the article.

 

8. Materials and methods. The techniques and equipment used must be described in a specific and logical sequence that shows the development of the research so that they can be reproduced. The sources of the materials, their state of purity and the detailed description of the equipment should only be included when they are very specific or novel. The procedures described by other authors should be avoided; but, if they have been modified, the details of that modification must be included.

 

9. Results and discussion (the discussion can be given as a separate section). The results must be presented in a logical, objective and sequential manner through texts, tables and figures. These last two supports should be easy to read and should be interpreted autonomously, although they should always be cited in the text. When the results are supported by statistical calculation, the origin of the data and the statistical method used must be mentioned. Tables must have a title and be identified by continuous Arabic numerals. Figures (photographs, drawings, graphics and maps) must appear with a title and be identified by Arabic numerals. Computer processed figures are accepted (the original figure must be sent unprocessed to verify that there are no ethical flaws). Black and white or color photographs are accepted. The discussion should be brief and limited to the significant aspects of the work, however, it should be complete and exhaustive, contrasting the results obtained with the most current literature on the subject, it should be explained to what extent the results obtained contribute to the solution of the problem and can be translated into recommendations, applications, suggestions, hypotheses, etc.

 

10. Conclusions. They must be based on the results obtained. If possible, they should offer a solution to the problem described in the Introduction.

 

11. Conflicts of interest. Authors should refer any financial relationship they have and that could lead to a conflict of interest in relation to the published article. In the case of sponsored studies, the authors must indicate whether they have had full access to the data and are responsible for the integrity and accuracy of their analysis. Likewise, the authors must indicate any family or friendship relationship, which could incorrectly influence the duties and responsibilities of the reviewers and/or the editorial team itself.

 

12. Acknowledgement. If it is necessary to show gratitude to the people or institutions that make a significant contribution to the work, these should be brief and concrete.

 

13. References. Should follow the APA style recommendations, be from the last 10 years (except for those metodologicals) and do not exceed the limit of 30 references. In the body of the Text, only published references will be accepted, mentioning the author's last name, followed by the year of publication in parentheses, for example: Rodríguez (1997). When there are three or more authors, the Latin expression et al. should be used, for example: López et al. (1996) If the reference is made at the end of a sentence, the author and the date are given in parentheses, for example: (Rodríguez 1997; López et al. 1996).
