EDITORIAL POLICY

The journal accepts original and unpublished papers in Spanish and English, on topics related to irrigation and drainage, agricultural mechanization, energy in agriculture, and related environmental aspects. These can be original articles, technical notes, reviews and points of view, letters to the editor, summaries of doctoral theses, master's degrees, specialties and technical discussions about a published article.

Original article is understood to be one based on research work in which the scientific method has been applied and the effect of different treatments on the response of a system has been studied, as a methodology to verify or reject a work hypothesis. These are prioritized by the journal.

Technical notes are articles based on experimental or development work that present novel methodological aspects or results that the author wishes to publish before finalizing their development or research.

Review and points of view are understood to be those writings based on the analytical review of scientific articles or research reports, in which the author provides his point of view on the subject and establishes conclusions regarding the current state of knowledge of the same.

In the letters to the editor section, the Ingeniería Agrícola journal will publish those it deems appropriate, which must present opinions or comments from the scientific community, editorial notes from the journal's management on certain topics or commemorations. The purpose of this part is to disseminate information or encourage discussion on topics published in the pages of this journal or of interest to the scientific community.

The thesis summaries section is intended to publicize the summaries of the content of the theses presented annually for defense before IAgric courts and the Permanent National Court of Agricultural Engineering of the Republic of Cuba.

The works that are sent must adhere to these norms and will be evaluated by the Editorial Committee or by whom it designates, before being published.

All work to be sent for possible publication in this journal must be accompanied by a letter of intent addressed to the Editor, which includes a brief description of the most important findings and indicates the institution, address, telephone, fax, and email address of the responsible author. , with whom the journal will maintain contact (no more than one double-spaced page, written in Times New Roman 11, the work must be sent in printed original, with data of the responsible author (institution, address, telephone, fax and email) in double-spaced letter-size paper, with 2.5 cm margins on all four sides and with numbered lines, the pages, including those of the tables (tables) and figures, will be numbered progressively. The text should not exceed 12 pages, for a scientific article and eight for a technical note, including tables (tables) and figures.In the first version, each table (table) or figure should be inserted in the text, in the other arranged versions the text will be written in continuous, without collation of tables (tables) and figures. The tables (tables) and figures will only have the essential information and in no case will they repeat the data that is presented in another way, the units of the International System of Units and Measurements (SI) will be used.

A space is left between the number and the unit of measurement (5 m, 42 oC ). No space is left between the number and the unit when it comes to percentages, angles and measures of longitude or latitude (45o, 15%, 30o15´5´´N). Spaces are used to divide large numbers into groups of three, both to the left and right of the decimal point (143,570 and 21,345,678). Four-digit numbers are written without a space and without a comma. A decimal point will only be used when writing figures referring to money (100.00 pesos), in all other cases a comma (100.00 m) will be used. Nouns are not mixed with units of measurement (correct: the water content is 20 mL kg-1; incorrect: the content is 20 mL H2O kg-1).

Rounding numbers follows three simple rules:

1) If the first two digits to be discarded are less than 50, the previous digit does not change. Example 5.44236 rounds to 5.44.
2) If the first two digits to be discarded are greater than 50, 1 is added to the previous number. Example: 5.44725 is rounded to 2.45.3) If the first two digits to be discarded are 50, 1 is added to the previous number if it is odd and it is not changed if it is even. Examples: 5.4350 and 5.4450 round to 5.44.

If there is only one figure and it is less than 10, it must be written in words (five provinces, six municipalities, nine neighborhoods; unlike 12 countries, 46 states. However, if that figure is accompanied by a unit of the International System of Units and Measures must be expressed as a number (4 mL , 7 kg, 3 h).

Manuscripts, figures and tables should also be delivered on a compact disc in a recent version of Word for Windows. The figures must be in a format that allows for subsequent modifications, regarding the size of the numbers on the axes, the thickness of the lines on them, and the text of the legends.

All the work must be written in Times New Roman font (including numbering in axes, content and figure legends). The title in Spanish will be written in size 18 in bold. The Title in English, size 18 too, but without bold. The rest of the text must be written in font size 11, except for the footnotes, which are in font size 9.

-Bibliographic references. To make the list of bibliographical references of the material cited in the text of the article, the indications that are detailed with examples in the Harvard guideline will be followed, although it is recommended to use the CSL file that contains the style of the journal called Revista Ingeniería Agrícola ( Spanish ) which will be available on the site https://www.zotero.org/styles/, which can be loaded by a wide range of bibliographic managers such as Zotero , Mendeley . Papers , among others.

Each original document must have at least 15 bibliographical references (of which 50% must belong to original articles published in scientific journals), in Times New Roman 11, alphabetically ordered, justified, with 1.5 line spacing and only The works cited in the text will be included in it. Each article must comply with the Price index, that is, 60% of the bibliographic citations must correspond to the last five years, except in the cases of Review Articles because the references must cover a wide range of time.

Other aspects to take into account

The tables or charts must be made according to the table autoformat used in Microsoft Word, with the Basic Table 1 style, as shown in the example of Table 1, they do not have vertical lines. Column and line headings will be in lowercase, except for the first letter of the heading. Only the number of significant figures necessary will be used. The tables or charts will not be larger than a letter size page considering the margins.
Maps and figures should not exceed one letter page, with specified margins. In a figure what is interesting to highlight is the content and not the axes. Consequently , the thickness of the latter must be less than that of the interior lines. The background of the figures must not have lines, and their background must be white, as shown in the example of the Figure.

Acknowledge . They may be included at the end of the text, after the Conclusions and before the

Bibliographic references.

Statistical methods

Mean separation procedures are often misused. This can result in incorrect scientific conclusions. Multiple comparisons of means (LSD) should be used only when the treatments do not have a well-defined structure (for example, studies to compare natural systems that do not depend on humans, that are not homogeneous in agricultural and industrial experiments or of another nature). Authors should be aware of the limitations of multiple comparisons of means tests when little information is available on the structure of the treatments ( Chew , 1980; Nelson & Rawling , 1983; Carmer & Walker, 1985 ).
logical structure, orthogonal contrasts between them are used.
