Focus and scope
The Journal of Dry Zone Agriculture (JDZA) publishes research of outstanding significance in all aspects of dry zone agriculture including agronomy, agricultural biology, food and nutrition, soil science, animal science, agricultural engineering, and agricultural economics.
Type of paper
Research papers - Original full-length research papers related to agriculture which have not been published previously, except as an abstract, and should not exceed 6,000 words excluding references. The minimum word count should be 3,000 excluding references.
The journal is published in two issues per volume annually.
Open access policy
The Journal of Dry Zone Agriculture provides immediate open access to its content to share and adapt.
From December 2021, articles are published under the terms of a Creative Commons Attribution 4.0 International License (CC BY 4.0) which allows reusers to distribute, remix, adapt, and build upon the material in any medium or format, so long as attribution is given to the creator. The license allows for commercial use.
The copyright of all published articles in the JDZA is retained by the publisher of the journal (Faculty of Agriculture, University of Jaffna, Sri Lanka).
Article processing fee
There is no fee for processing and publication of articles.
The authors should include the persons who have contributed sufficiently to the work submitted to the journal. Changes cannot be made in the list of authors after submission unless all authors agree the addition of new author with the reason in detail for the addition of author.
Plagiarism policy and article review process
If any part of already published work is used in the manuscript, they should be cited properly or in any case, if required they should get permission from the previous publisher or copyright holder as required. All manuscripts will be screened using plagiarism detection software and assessed by the editors for suitability for the journal before sending for review. The screened manuscripts will be sent to a minimum of two independent expert reviewers for review (double-blind review). The editorial board is responsible for the final decision regarding acceptance or rejection of articles.
Guidelines for preparation of manuscript
The language of publication of the articles is English (British English). Manuscript should be prepared in MS Word as .docx format (Word 2013 or higher). The style of writing should conform to acceptable English usage. Slang and jargon should be avoided. Non-standard or uncommon abbreviations should be avoided, but, if necessary, they must be defined at their first mention. The script should be free of errors, double spaced throughout with 2.5 cm margins on all sides. Pages should be numbered consecutively at the bottom right. Continuous line numbers should be added throughout the text. The font style should be Times New Roman and font size 12 throughout the paper.
Title page should be submitted separately. It includes the title of paper, names with initials and affiliations of all authors. Corresponding author should be indicated by an asterisk (*) and ORCID ID, e-mail address, postal address, telephone, and fax numbers of corresponding author should be given.
The manuscript should not contain author names and affiliations. Author should ensure that the manuscript does not contain any clues to the authors’ identity. If the author wants to include any such details in the manuscript, that could be done after review is completed, if the manuscript is accepted for publication. Manuscripts should be organized as follows: Title, Abstract, Keywords, Introduction, Materials and Methods, Results and Discussion, Conclusions, Acknowledgements, Declaration of Conflict of Interest, and References.
Title should be concise, informative, and typed in ‘Sentence case’ bold letters. Avoid using abbreviations in the title of a paper.
Abstract should have 200 - 250 words. The abstract should not contain any references. It should outline objectives and methodology together with important results and conclusions.
A maximum of six keywords should be provided separated by a comma in alphabetical order.
It should be concise and well-focused to the research work done. It should provide adequate background of the research and state the objectives of the work. A detailed literature survey or a summary of the results should be avoided.
Materials and Methods
New methods should be described in such a way as to allow the work to be reproduced by an independent researcher. Established methods should be mentioned in brief with references. Any modifications to existing methods should also be described. A paper reporting the results of the experimental investigations on human subjects or on animals must provide evidence of approval obtained from an ethical review committee. Statistical analyses done should be mentioned where applicable.
Results and Discussion
The results should be concisely and logically presented. Only data essential for the main conclusions emerging from the study should be included. Repetition of the same results in figures, tables or text should be avoided. Long discussions should be avoided. The discussion should deal with the interpretation of results. It should logically relate new findings of earlier ones. Avoid extensive citations and discussion of published literature.
Unqualified statements and conclusions not completely supported by the data should be avoided. All hypotheses should be clearly identified as such.
Acknowledgements should be brief and made for funding sources, scientific and technical assistance and not for routine help in preparing manuscripts.
Declaration of Conflict of Interest
Authors should declare any interest or relationship, financial or otherwise, that might be perceived as influencing on the research. If there are no conflicts of interest, indicate it as ‘Authors have no conflict of interest to declare’.
The list of references must be as updated as possible. References to the literature must be indicated in the text and tables as following the general procedure. The references should be in alphabetical order at the end of the manuscripts. Unpublished data and personal communications should not be listed in the references but may be mentioned in the text. Reference to work ‘in press’ implies its acceptance for publication and may be listed under references.
In each reference, all the initials of the author must be given after the surname. The year of publication should follow the author’s name. This should be followed by the full title of the referred publication.
When journal articles are listed, the journal names should be given in full and it should be indicated in italics and followed by the volume number, the issue number in parentheses and then the inclusive pages. When books are listed, the order should be: author(s), year, book title, volume number, edition, pagination/inclusive pages, publisher and place of publication. The book title should be indicated in italics. When sections of a book are listed, the order should be: authors of section, year, title of the section, title of the book, edition, inclusive pages, publisher and place of publication. Wherever available, digital object identifier (DOI) should be provided.
Citation in the text
Cite references in the text by name and year in parentheses. When two or more references are to be cited together, arrange the citations in alphabetical order, separating them with semicolons. Some examples:
… fully hydrogenated fats are blended with liquid oils as the feed stocks of interesterification (Zhang et al., 2000).
… with low or zero trans fatty acids and the results were promising (Abdhul, 2005; Goli et al., 2008; Zhang et al., 2001).
… trans-free margarine formulations and most widely used enzyme for the interesterification is Lipozyme TL IM (Ferreira-Dias, 2013).
… fatty acids can be obtained by enzymatic interesterification (Huang and Akoh, 1994).
This result was later contradicted by Becker and Seligman (1996).
