    Agronomía Mesoamericana journal was born on the XXXV Meeting of the Central American Strengthening of Crops and Animals Cooperative Program (PCCMCA, in Spanish), held in Honduras in 1989. Its purpose was to disseminate the research results that are presented in these annual meetings. The first volume was published and distributed in 1990, during the XXXVI Meeting of PCCMCA in El Salvador. Nowadays its objective is to disseminate scientific information, in Spanish or English language, through the publication of articles, short communications, technical notes and literature reviews, related with food and agriculture sciences from anywhere in the world, emphasized in tropical and subtropical zones, especially from Mesoamerica and the Caribbean.

    In accordance with the rules from the Agronomía Mesoamericana journal, the authors of the scientific works have the following rights over their published work: they can present them in public, prepare derivative works, reproduce and distribute them. Users of the journal can mention the information contained in the published material (as long as they cite them correctly, otherwise they recur in plagiarism) for teaching and research purposes.

    The work’s receipt date will be granted after it has complied with the Writer’s Instructive Guide and the Format Guide, both can be consulted in the electronic journal         

     All the works must be submitted electronically, writers can register in the following link: Also, the works must be original, unpublished and cannot be proposed partially or completely to another journal. Every publication is going to be disseminated in printed and electronic media, including the internet, according to the disclosure rules and the transfer of rights from the authors.

    Agronomía Mesoamericana does not charge for submissions, editing, and publication. Works will be peer-reviewed by external experts, with experience on the subject; these will be selected based on their academic formation and publications on scientific journals.

    Peers will analyze the works in order to determine the validity of the proposed objectives, the methodology used and the obtained results, as well as its contribution to or impact on the scientific field. They will be granted a month to provide the review results. If the process is delayed, it will be sent to other specialists and the author(s) will be asked if they agree to wait longer for the publication or to retreat from the editing process. Once the work has been approved, the final version will be sent to the authors for them to review and approve it in a maximum term of five business days.

    The Editorial Board reserves its right to assert the works according to their impact and content.

    Types of accepted publications starting from volume 28(2) of 2017

    Article: the result of a profound and detailed investigation, is novel, Must present an original and/or innovative theme, with a new approach when dealing with topics already discussed. Carry out a new or different methodological application, which must be well-founded. With all of the elements of an article, including title, the authors’ full name and affiliations,, summary and rightfully translated abstract, keywords, introduction, materials and method, results, discussion, conclusion and cited literature (relevant and recent citations must not be omitted) It must include an appropriate number of charts and substantial and relevant figures that demonstrate and enhance the merits of the work for a publication in an indexed journal. It’s a text with the academic character that demands the compliance of certain norms about its general structure and content. These fundamental aspects are determined by the type of readers and divulgation media. The use of specialized language and formal tone in which the article is written facilitates the access to the information and therefore, its comprehension. It must carefully be written to avoid unnecessary subjects, in order to communicate its content in a clear, summarized way, without disregarding the essential citations and references. It should include everything that was researched and not fractionated in order to originate two or more articles. The articles must not have an extension of more than thirty pages in Word. A single trial, conducted in a single locality, during a time of the year, with a specific or restricted genetic scope of crop, plant, animal, pathogen or other, can be considered as preliminary work to support a later investigation, for Which may not be accepted as an article.

    Technique notes: They refer to three types: 1. Reports of significance, urgency and interest, but should contain relevant preliminary results (e.g., describe a new weed, a new wild species, a new pathogen). 2. The publication of the development of innovative techniques or methodologies, preferably, or their adaptation, modification, promotion and dissemination of a scientific nature, of interest to the Mesoamerican region. These include improvement methods, statistical analyses, field, greenhouse or laboratory apparatus or instruments. 3. Experimental work of various kinds, aimed at demonstrating the importance, potential, timely use, profitability, for example, "Planting densities for the production of high quality seed", "Containers for the conservation of local germ-plasm grain seed in rural areas", which are of great importance and commercial impact, but does not correspond to the structure of an article describing original research results, in search of new contributions to science or scientific advances. The document must not exceed the 20 pages in Word. It can address the results of the practical trial on a very specific problem, based on a general use procedure in the profession.  Some examples are:

Their objective is for indexation and bibliographic information selection. As a reference, authors can consult the FAO AGROVOC Thesaurus ( and the agricultural thesaurus from the  National Agricultural Library de United States Department of Agriculture
      ( General words must not be included, for example, performance, variables, plant, differentiation, tropic, crops, etc.

    • ABBREVIATIONS AND SYMBOLS: The Mesoamerican Agronomy journal will only accept the measurements from the International System of Units.

    • INTRODUCTION: It must include the purpose of the investigation, the most relevant precedents related to the research topic and objective. The importance of the problem within the study field, limits to the investigation. Al the information must be backed with citations that can be easily reached through documentation centers, libraries or online. If there are two or more authors, writers must write “et al.” after the first last name, for example, a) “… the methodology proposed by Gómez et al.”. b) “…this method is similar to the one used by other authors (Hartman, 1974, Jackson et al., 1977). Every mention of animal or plant species must include their scientific name, and when it is part of what’s being studied in the paper, it must also include its biological classification. Every mention of the scientific name afterward will be only the initial of the genus plus the species. Every mention of the scientific name must be in italic (check the terminology in Association for Plant Taxonomy plant, International Code of Botanic Nomenclature). The generic names used as vernacular do not need a capital letter, for example, bean, corn, etc. Figures and charts must not be included.   

    • MATERIALS AND METHODS: These are basic elements of the investigation and the ones that generate results. Materials (soils, plants, seeds, cows, goats, etc.) must be clearly described: full scientific name (International Code of Nomenclature for algae, fungi and plants, 2012). Physical, chemical, and soil type analysis. Name of the variety, cultivar, or the number collected in wild plants (location of the herbarium). Origin of the seed, quality used, and indicate where it is available. Characteristics of the animals used, which includes its origin, type, age, etc. As well as the witness (s) employed. The methods must clearly indicate the variables that are being measured and their precision, this requires that the experimental design, experimental unit, sampling method and type of data analysis ought to be included in this section. Also, the description of the treatments and variables evaluated. Cultural practices and experiment handling. Also, the place and period where the investigation took place and climatic conditions, if necessary. As an example in tolerance studies of plants followed, the water available to the plant, type of soil and moisture retention during the experiment, relative humidity and room temperature should be described.

    • RESULTS: They must as summarized and precise as possible. They must begin with the main result according to the investigation’s main objective. Data deriving from the application of the proposed methodology shall be presented in a clear, complete and orderly manner, but at the same time concise, based on findings of fact and not suppositions, and must be expressed separately in figures or charts (include in an additional file the data that originated them, for formatting purposes). The text must not include information that is contained in the figures or charts. The information obtained through the analysis of variance will be described in the text. It must show only the essential information, and not leave room for interpretation or the need for summarizing the information to the reader.

    • DISCUSSION: The obtained information will be analyzed. It must explain the importance of comparing the information with similar studies and indicate why there were o were not significant differences. When the results of similar investigations are compared, it should be an interpretation and clarification on why there are similarities or differences (for example: because of the site, the genetics, employed methodology, etc.). The significance of the results must be discussed and explain those that were unexpected or contradictory. Follow-up studies on what was obtained can be proposed. Commercial recommendations on a very specific work will not be allowed. Do not include literature review of the work justification, which should be placed in the introduction.

    • CONCLUSIONS: Conclusions must be presented in very concise and clear writing, stating the evidence that backs them up. They must be consistent with the work’s objectives and respond to them. Summarizing the results or repeating what was explained in the paper will not be allowed.

It must clearly identify the information given, place (s) where it was done, period or year of execution. Images, photographs, drawings, and a map will qualify as figures. Tables and figures must be presented preferably in a simple and comprehensible format, instead of a complicated, hard to interpret one, or based on general information that wasn’t put through a due summarizing process (the author is the one responsible for analyzing and summarizing the obtained information). The best way to communicate results and to not repeat the information in the tables and figures must be employed. Photos must be sent in a separate file, with a minimum resolution of 300 dpi and in JPG, EPS o TIFF format. They must be legible. Tables, figures, photos or maps must appear immediately after they are mentioned. Under no circumstance, they will be accepted as an annex or appendix. Avoid the use of abbreviations in the titles of every column in the table. Abbreviations of any type included in the body of the table or figure must be clarified, with the exception of the ones that are universally known. Frames with more than one extension page are not supported, and those that span a page must be justified. It is recommended that tables be drawn up only with the most representative data and indicate the most important variations. Also, very small tables with little information are not accepted, the data must be included in the text.
