Author Guidelines

The Jordan Journal of Agricultural Sciences (JJAS) is an international refereed scholarly journal published in both English and Arabic. It is the official peer-reviewed publication of the Deanship of Academic Research and Quality Assurance of the University of Jordan, under the sponsorship of the Board of Directors of Scientific Research Support Fund of the Ministry of Higher Education and Scientific Research. . It is a continuation of Dirasat: Agricultural Sciences.

The purpose of the JJAS is to enhance the research and knowledge base in agriculture and related sciences from an international perspective. The JJAS is interdisciplinary in scope and content. It publishes articles broadly relating to agricultural sciences. These include plant and animal production, plant protection, food sciences, land and water, environment, range and forestry, agrobiotechnology, agribusiness, agricultural economics, and extension and rural development. 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 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, which have general implications. The length of a full paper 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 and references.
Research Note (4 to 8 pages): a short note (communication) presenting the results of complete small 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 (normally 5-10 printed pages): A critical synthesis of literature in a particular field on a certain topic of current interest written by eminent scientist(s) .

Manuscript Peer Review Process
Manuscripts should follow the style of the journal and are subject to both 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.

Reviwers 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 a paper 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.

All illustrations (line drawings and photographs) are classified as figures. 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:
a. 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.
b. 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.
c. 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.
d. 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.
e. 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 inculde 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.

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.
g. 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.
h. Acknowledgment: The source of financial grants, other funding and technical assistance must be acknowledged.
