The Bhutanese Journal of Agriculture focuses on original and innovative scientific research relevant to sustainable development of agriculture sector in Bhutan.
Papers should address a scientific community interested in agriculture, and cross-cutting themes including; markets, biodiversity, irrigation/water, soils, farming systems and, climate change aspects of sustainable agriculture development in Bhutan.
Types of contribution
Research articles: (5000 – 7000 words) the articles should not have been previously published elsewhere.
Present original and innovative research insights;
Be well researched and documented
Clearly describe the research methodology including design and statistical analysis used where appropriate;
Results should be presented based on sound facts, scientific procedures and well founded arguments;
Be embedded in the relevant local, national or international debate;
Refer to the most recent academic literature on the issues discussed;
Be presented in a clearly structured and comprehensible manner; in the interest of disciplinary and interdisciplinary communication.
Short communication (2000-4000 words): A concise and complete with description of an investigation. The bulk of the text should be organized in a continuous form with separate sections such as Introduction, Materials and Method, Results and Discussion. It should, however, include a short Abstract and a list of keywords at the beginning of the communication, and Acknowledgements (if any) and References at the end. These components are to be prepared in the same format as used for full-length research papers.
Preparing your submission
Manuscripts submitted to the Bhutanese Journal of Agriculture should strictly conform to the following instructions and technical guidelines:
Total length of the article:
Maximum 5000-7,000 words including spaces and list of references for full length articles and 2000-4000 words for short communication.
The first page of each manuscript starts with the title of the paper which should be typed in bold-faced print using both upper and lower case letters and set in the centre of the page. The title should be as concise and catchy to reflect what the paper is all about? Abbreviations are not permitted in the title. The title should be in Times New Roman with 14 point bold.
Author(s) and agency
The names of the author (s) should be written in full. Indications of titles, professorial ranks or other professional titles should not be used. The address of the agency to which the author belongs to shall be written as footnote. Please provide the email address of the first corresponding author only in italic, 8 Times New Roman.
Abstract and key words:
The abstract consists of 150 – 300 words in one paragraph. The abstract should summarize pertinent results in a brief but understandable form. The abstract should start with a clear statement of rationale, brief objectives of the experiment/research/study and methods, results and must conclude with one or two sentences that highlight important conclusions. References are never cited in the abstract. Abstract should be indented by 0.2 inch on left and
right and centre justified with 12 point italic, Times New Roman. Below the abstract, list three to five key words that best describe the nature of the research.
The term “Keywords” is typed in bold-faced print followed by a semicolon. The first letter of each key word is capitalized and key words are separated by semicolon. Keywords should include the main attributes of your papers; should be between 3-5 keywords; font 12 point italic, Times New Roman.
The introduction starts on a new page following the abstract. The introduction briefly justifies the research and specifies the hypotheses to be tested. Discussion of relevant literature should be cited to support/justify your research in the introduction. Introduction should be divided in to concise paragraph, each paragraph dealing with a topic of your research theme. Mention of objectives of the study or research will be not done under separate heading. If at all necessary, it can be included in the introduction. Objectives should be clear, concise and realistic.
Materials and Method
Materials and Method should be clearly described in a step-by-step guide for others to understand and follow.
Study area, location and their description must be given with illustration if possible. Authors may supply latitude and longitude coordinates for the study area/location referred to. For any equations used in the papers, standard equation format should be followed. Equations must be numbered and placed directly in the text with serial number. Figures, tables, and boxes must be referred to in the text, in numerical order.
The data should be analysed using standard statistical model. The use of incorrect
or inadequate statistical models to analyze and interpret data is not acceptable. The statistical model, classes, blocks, and experimental unit must be described. Statistical test (S) used should be clearly stated. Both confirmatory inferential statistics such as LSD, r-value, 95% CI, etc should be at P-value of 95% confidence level and descriptive statistics such as standard error, standard deviation, CV%, etc should be given where appropriate.
Results and Discussion
Results should be presented in tabular or graphical form with description of key results in the text. The text should explain or elaborate on the tabular/graphical data, but numbers should not be repeated extensively within the text. Sufficient data with index of variation should be presented to allow the reader to interpret the results of the experiment.
Discussion should interpret the results clearly and concisely and should integrate similar literature results with the research findings to provide the reader with a broad base on which to accept or reject the hypotheses tested.
Conclusion: This section should consist of 300-500 words. Conclusion section should highlight key findings and their implications to relevant users of the information. It should explain in lay terms, without abbreviations, acronyms, or citations, what the findings of research/study are. Do not repeat statements made in the result and discussion sections.
Acknowledgement. Acknowledgement should be made to key persons other than authors and co-authors including the anonymous reviewers and funding agencies. However, it should not be lengthy.
Tables and Boxes
Tables are used to present numerical data in a self-explanatory manner. They should be intelligible without consulting the text and should not duplicate data already given in the text or in illustrations. Any abbreviation used in a table must be defined in that table. All tables should be cited in the text. Arabic numerals are used to number tables. The table number (i.e. Table 1.) is typed followed by a period. The title of the table should be given just above the table with only the first letter capitalized; font 12 Times New Roman. Do not use a period at the end of the title. Column headings should have the first letter of each word capitalized
while the names of variables are typed with only the first letter capitalized (i.e. Average growth rate). For numerals less than 1, insert a zero to the left of the decimal point (columns should be set up so that decimal points are aligned). If there are no data for a particular entry, insert a dash. If an explanation is necessary, use an abbreviation in the body of the table (e.g. NA) and explain clearly what the abbreviation means.
In boxes, include caption in a title bar (topmost line across entire box)
Your submission may have no more than 5 tables or boxes in total
Very large tables and long lists should be avoided.
Tables should be inserted as enhanced metafiles
No border lines, only boundary lines will be used, 10 point, Times New Roman and no colors
Text in tables must always be horizontal; no bold
Table 1. Mean growth rate of chilli plants
No. of leaves
Possible file formats: .JPG, PDF, .XLS, .GRF.
The figures should be inserted as enhanced metafiles
Figures should be black and white print
The submission should not have more than 5 figures (including photos, diagrams, maps)
Put captions below the figures; 12 point Times New Roman
No color, but choose different shade(s) that is appropriate for black/white printing
Photos, illustrations, flow charts can be used if necessary
Example (Figure 1)
Figure1. Effect of treatments on growth rate of broccoli plant
Note: For editorial convenience, authors are also required to submit charts (figures) and tables as separate files with appropriate corresponding file references as they appear in their manuscripts.
All literature cited in any part of your paper should be listed at the end of the body text file in a section entitled “Reference,” without numbering. The references should be arranged in alphabetically by author and then chronologically, giving the complete unabbreviated source citation.
For convenience and ease of use for our contributing colleagues in the research centres and our field personnel, BJA has adopted the APA (6th) style of referencing.
Use author–year style in chronological, then alphabetical, order. Use “et al” with three or more authors. Use colon and number to indicate page reference.

• According to Abercrombe et al. (2008) . . .
• It was shown that . . . (Abercrombe et al., 2008).
If there are several works by the same author(s), they should be arranged
chronologically by year of publication with oldest reference first; if several works by the same author were published in the same year, arrange them alphabetically and add a letter to the year of publication, e.g. 1999a, 1999b, etc
For a group, the name of the group is written in full the first time they occur in an intext citation. o If you wish to abbreviate names, write the name in full the first time that it occurs, and place the abbreviated form in brackets. In subsequent citations, you can then just use the abbreviation.
