The Jordan Journal of Agricultural Sciences (JJAS) is an international double-blind refereed scholarly journal published in both English and Arabic. The purpose of the JJAS is to enhance the research and knowledge base in agriculture and related sciences from international perspectives. The JJAS is interdisciplinary in scope and content. It publishes scholarly articles broadly relating to agricultural and allied sciences. These include but are not limited to agricultural production and protection, agricultural environment and management, agricultural technology and development, agricultural and food economics and polices, agriculture, food. nutrition, and health, and agricultural and food engineering. Articles must be original and should contribute to the advancement of knowledge.

Article Types:

The JJAS accepts submission of manuscripts of the following types:
Regular full original research articles: These should contribute new knowledge to the field in which the research was conducted and focus on current or emerging issues. The article can also describe the methodologies and practical application of specific research and appropriate technologies, with general implications. The length of a full article should be the minimum required to describe and interpret the work clearly and no longer than 15 printed pages. The manuscript should include a title page, abstract, introduction, objectives, materials and methods, results and discussion, conclusions, acknowledgments, conflicts of interest, and references. Research Note (4 to 8 pages): a short note or communication presenting the results of complete short investigations or giving details of new models or hypotheses, innovative methods, techniques or apparatus. It is a short article having all the features of a regular research article with 2500 words limit. Review Article (5-10 printed pages): A critical synthesis of literature in a particular field on a certain topic of current interest written by eminent scientists .

 Manuscript Peer Review Process:

Manuscripts should follow the style of the journal and are subject to both blind-peer review and editing. Manuscripts that do not conform to these requirements and the manuscript format may be returned to the corresponding author prior to review for correction.
Reviewers evaluate manuscripts content and ensure readability. The acceptance criteria for all papers are the quality and originality of the research and its significance to the wide interests of the readership. The reviewers' recommendations determine whether the article will be accepted/ accepted subject to minor changes/ subject to resubmission with significant changes/ rejected if the manuscript contains major defects which may or may not be correctable. Authors are expected to react positively and must address those changes recommended by reviewers objectively and scholarly. The Editorial Board reserves the right to reject any manuscript, and to make suggestions and/or modifications before publication.

Submission Guidelines to Authors:

When preparing the manuscript for submission, author s are required to adhere to the following:

  1. The manuscripts should be prepared as Microsoft Word files, not more than 30 pages (7,500 words) and submitted electronically through the JJAS online submission system. Lines should be double spaced, except between paragraphs and tables. Times New Roman font, 12 or 13 font type is used for all text in the manuscript, with 2.5 cm (1.00 inch) margins on all sides. All major headings should be in Bold with first letter caps only for each word. Indent the first line of each paragraph and prepare all copy flush left; do not use full justification.

Tables and figures should be numbered consecutively in Arabic numerals and must be included in the manuscript body immediately following the paragraph where it was first mentioned. Column headings for tables should be brief, with metric units of measurement in parentheses, and all abbreviations should be defined in footnotes to the table.
  3. Figures and other graphic material should be sent electronically in any common file format, provided that quality and resolution are assured. Only scientifically necessary illustrations should be included. The table and its footnotes, or legends of the figures should be self-explanatory and understandable without reference to the text.
  4. The manuscript should be presented in the following order:
  • Covering letter and Copyright: By submitting a manuscript, authors certify that they are reporting original work that has not been published fully or partially or be under consideration for publication by another journal. Authors must declare any financial support or relationships that may pose conflict of interest in the covering letter. Copyrighted data may not be submitted to JJAS. Previous publication of part of the data in conference proceedings must be cited in the manuscript.
  • Title page: The title page should include, the Manuscript title in bold with the first letter of all major words capitalized of no more than 80 characters. It should include also the Authors’ full names, in Arabic and English academic rank(s) affiliation(s), complete mailing addresses, telephone and fax numbers and e-mails.
  • Abstract: All manuscripts must include brief Abstracts in English and Arabic (with identical information) on separate sheets of no more than 200 words. Abstracts should be organized in a single paragraph and must contain objectives, methods, and informative digest of the significant findings and conclusions of the paper that are intelligible without reference to the main text. Key words or phrases (6-10 words) should be provided below the Abstract and be selected from the body of the text and not a duplicate of the title words to describe the paper and to assist with indexing of the article.
  • Introduction: This section should include sufficient background information to describe the issue addressed in the manuscript, a clear aim of the study and a relevant literature review which discusses similar research published on the topic. The introduction serves as a theoretical, conceptual or operational framework which helps to put the research work into context. The purpose and the specific objectives of the manuscript should be clearly stated and be supported by the theoretical/conceptual framework.
  • Materials and Methods: Methodologies or experimental procedures should be concise but provide sufficient detail for others to verify the work or to allow the work to be repeated by others. The essentials of methods/ procedures of the study and its duration should be reported. These include experimental design/ sampling procedure, tools of data collection and the performed statistical tests. References for established methods and statistical procedures should be cited. The validity of the methods is a key criterion in the referee process.

    If the work involves the use of human subjects, the author should ensure that the work described has been carried out in accordance with The International Code of Ethics (Declaration of Helsinki) for experiments involving humans. The manuscript should be in line with the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in International Journals and aim for the inclusion of representative human populations (sex, age and ethnicity) as per those recommendations. The terms sex and gender should be used correctly. Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.

    All animal experiments should comply with the ARRIVE guidelines and should be carried out in accordance with the U.K. Animals (Scientific Procedures) Act, 1986 and associated  guidelines, EU Directive 2010/63/EU for animal experiments, or the National Research Council's Guide for the Care and Use of Laboratory Animals and the authors should clearly indicate in the manuscript that such guidelines have been followed. The sex of animals must be indicated, and where appropriate, the influence (or association) of sex on the results of the study.

  • Results and Discussion: Results should be presented in a proper format and in logical sequence in the text, tables and figures. This section summarizes all the collected data and mention relevant results, even those that were not expected. Repetitive presentation of the same data in different forms should be avoided (e.g., tables and figures). Any measurements or other information that may require explanation should be defined. Levels of statistical significance should be indicated, as well as any other factors crucial to the outcome of the study. Discussion includes the author’s interpretation of the results and considers the results in relation to any hypotheses advanced in the introduction and place the study in the context of other works.
  • Conclusions: Conclusions must be supported by the results of the study. The relationships/ differences between the conclusions and the research foundation contained in the theoretical base should be discussed. Based on conclusions, reasonable recommendations or the practical application of specific research and appropriate technologies, which have local or general implications should be presented, as well as suggestions for future research.
  • Acknowledgment: The source of financial grants, other funding and technical assistance must be acknowledged.
  • Conflicts of interest: The authors must declare any conflicts of interest that may have with their research, or none.

    1. References:
    • a) The American Psychological Association (APA) 7th Edition Reference Style must be used. For detailed standards and procedures, please consult the Publication Manual of the American Psychological Association or the APA Style website at
    • b) In-text citation:

    - The reference is cited within the text by the author’s last name and year of publication between two brackets; for examples: for one author (Author, 2021); for two authors (Author & Author, 2021). For three or more authors, the first author is cited followed by et al., and the year (Author et al., 2021).

    - If two or more in-text references are cited, they should be arranged in the order of year of publication, from the oldest to the newest. Example: (Author, 2015; Author, 2018; Author, 2020; Author, 2022).

    - If an author or reference is quoted or mentioned at the beginning of a paragraph or sentence or an author who has an innovative idea or finding, the author’s name is written followed by the year between two brackets. Example: Author (2021), Author & Author (2021), or Author et al. (2021).

    - Multiple publications by the same author(s) in the same years should be designated by the letters a, b, .etc. Example: (Author, 2021a), (Author, 2021b).

    1. c) Reference list entries include the four elements of the author, date, title, and source.

    - The list of references should be structured at the end of the manuscript in alphabetical order according to the author’s last name.

    • d) The authorrefers broadly to the person(s) or group(s) responsible for a work. An author may be an individual, multiple people, a group (institution, government agency, organization, etc.), or a combination of people and groups.

    - Invert all individual authors’ names, providing the surname first, followed by a comma and the author’s initials. Example: Author, A. A. Use a comma to separate an author’s initials from additional author names, even when there are only two authors. Use an ampersand (&) before the final author’s name. Use one space between initials. Example for two authors: Author, A. A., & Author, B. B. Example for three authors: Author, A. A., Author, B. B., & Author, C. C. Follow this style for 20 authors.

    - When there are 21 or more authors, include the first 19 authors’ names, insert an ellipsis (but no ampersand), and then add the final author’s name. Example: Author, A. A., Author, B. B., Author, C. C., Author, D. D., Author, E. E., Author, F. F., Author, G. G., Author, H. H., Author, I. I., Author, J. J., Author, K. K., Author, L. L., Author, M. M., Author, N. N., Author, O. O., Author, P. P., Author, Q. Q., Author, R. R., Author, S. S., . . . Author, Z. Z.

    • e) The daterefers to the year of publication of the work and should appear between two brackets. Example: (2020).

    - For unpublished, informally published, or in-progress works, provide the year the work was produced. Do not use “in progress” or “submitted for publication” in the date element of a reference. If a work has been accepted for publication but is not yet published, use the term “in press” instead of a year: (in press).

    - If a work is an advance online publication, use the year of the advance online publication in the reference. When the date of original publication is approximate, use the abbreviation “ca.” (which stands for “circa”): (ca. 2015). When a retrieval date is needed, use the following format for it: Retrieved September 17, 2020, from https://xxxxx.

    • f) The titlerefers to the title of the work being cited.

    - Titles fall into two broad categories: First, works that stand alone (e.g., whole books, reports, literature, dissertations and theses) and second, works that are part of a greater whole (e.g., periodical articles and edited book chapters).

    - For works of both categories, capitalize the title using title case style. Titles of works of the first category are italicized.

    - In the title case style, major words are capitalized, and most minor words are lowercase.

    - Capitalize the following words in a title: The first word of the title or that of a subtitle even if it is a minor word, the first word after a colon, em dash, or end punctuation in a title, major words, including the second part of hyphenated major words, and words of four letters or more.  Examples:

    Article title: Genetic Diversity among Single, Double, And Triple Cross Hybrids in Beit Alpha Cucumber (Cucumis sativus).

    Book title: Krause and Mahan’s Food & the Nutrition Care Process (15th ed.).

    • g) The sourceindicates where readers can retrieve the cited work. As with titles, sources fall into two broad categories: works that are part of a greater whole and works that stand alone.

    - The source for a work that is part of a greater whole (e.g., journal article, edited book chapter) is that greater whole (e.g., the journal or edited book), plus any applicable DOI or URL.

    - A location is not required in the source element for most works (e.g., do not include the publisher location for book references).

    - Works associated with a specific location (e.g., artworks, conferences) include location information in the source and, depending on the work, may also include a DOI or URL.

Digital Preservation Policy

Digital preservation can be seen as the set of processes and activities that ensure information which now exists in digital formats is backed up and distributed to guarantee continued access for the long term. The digital content of the journal is extremely valuable, and measures are in place to ensure both its current accessibility and long-term preservation. The preservation policy includes the following measures:
1. The published full text of the manuscript would be available in PDF format.
2. All of our electronic content (website, manuscripts, etc.) is stored on three different sources. Content on one server is online and accessible to the readers. The copy of the same content is kept as a backup on two other sources. In case of failure of one server, any one of the other sources can be made online and the website is expected to be accessible within less than 24-36 hours.
3. Abstracting/Indexing services: JJBA’s Abstracting/Indexing services store many essential information about the articles. Additionally, two of our journal’s Abstracting/Indexing services do not only archive the metadata about the article, but also the electronic versions of the articles. Therefore, copies of the articles are available to the scientific community through their systems as an alternative to the journals own.
4. Self-archiving: Authors may archive the final published version of their articles in personal or institutional repositories immediately after publication.
5. If journal stops publishing: We intend and expect to continue to publish our journal for a very long time. If, due to some rare, unfortunate circumstances, we are forced to stop publishing the journal, the manuscripts published in the journal will be kept online and accessible to the readers for at least 10 more years. This archive would be created to preserve all the digital content (especially published manuscripts) perpetually.
