Aims and Scope:
Pakistan Journal of Agricultural Sciences is published quarterly in a calendar year. It is devoted to the advancement and dissemination of scientific knowledge concerning all disciplines related to agricultural sciences. Papers are published on the understanding that they have not been and, will not be published elsewhere. The responsibility for the preparation of a paper according to the layout and style of the journal lies with the author(s). Research papers with drastic deviations from the format of the journal will not be accepted. Preference is given to articles of not more than 6 printed pages. The Authors are advised to give names of three potential reviewers including one foreign reviewer. They should also refer at least two articles from the previous issues of this journal. PJAS welcomes photographs for its title pages. The photographs should preferably but not essentially refer to an article published in that issue.


Title:
It should be concise yet informative. It should arrest the attention of a potential reader while scanning a journal or a list of titles. Title of the paper is in capitals. Authors' names are in lower case with initial capitals and their complete postal addresses in italics including e-mail and telephone No. Main section headings (Introduction, Materials and Methods, Results and Discussion, Acknowledgement(s), References) are printed in capitals throughout and placed by the left margin. All manuscripts must have a short title, up to six key words and an abstract (without writing the heading "Abstract" on it). The abstract should consist of no more than 200 words, be complete in itself and understandable without reference to the paper. It will be printed at the beginning of the paper in one continuous paragraph.


Introduction:
State the purpose, give only strictly pertinent references and do not review the subject extensively.



Materials and Methods:
These should be concise but allow confirmation of observations and repetition of the study.



Results:
Present your results in a logical sequence in the text, tables and figures. Do not repeat in the text all the data given in the tables and figures, emphasize or summarise only important observations.



Discussion:
Summarize the findings without repeating in detail the data in results section. Relate your observations to important relevant studies; point out the implications of the results and their limitations.



References:

List a minimum of pertinent references including at least two references from PJAS. References are listed alphabetically by surname. Secondly, use chronological order for papers with identical authorship. The sequence of names of authors (invert name of first author only), year of publication, title {lower case letters except for books, proceedings of international seminars/workshops and important research reports where capitals are used for first letters of various words), abbreviated name of periodicals, volume and number of first and last pages of the article. All reference entries must be cited in the body of the paper. Do not include unpublished material, except theses, in the references. Some example references are:

Aslam, M., M. Ismat, R.H. Qureshi, S. Nawaz and I.A. Mehmood. 1994. Paddy yield affected by planting techniques in a salt-affected soil. Pak. J. Agri. Sci. 31(4): 401-405.
Conjak, R.A. 1986. The winter biology of stream salmonids. Ph.D. Thesis, p.160. University of Waterloo, Ontario.
Steel, R.G.D. and J.H. Torrie. 1980. Principles and Procedures of Statistics. A Biometrical approach, 2nd ed. McGraw Hill Book Co., New York.
Wiseman, J. 1990. Variability in the nutritive value of fats and non-ruminants. In: Feedstuffs Evaluation (Ed. J. Wiseman & J.A. Cole), p. 24234. Butterworths, London.
Text citations should quote the surnames of the authors in one of two ways:

  • With the year in parentheses: “Ahmed (1991) has shown…….”
  • With the name and year in parentheses: “According to recent findings (Ahmad, 1991)…….”.

Multiple references should be as follows: Ahmed et al., 1993 and 1994; Ahmad et al., 1993a and b.

Abbreviations and Units:
Use of abbreviations should be minimized. Abbreviations are not allowed in the title, running head, or key words. Do not begin a sentence with an abbreviation. Do not abbreviate units of measures that are not preceded by a number (e.g., 8 kg). The international Systems of Units (SI) and metric units should be used. In decimals, use the decimal point, not the comma.

Tables and Illustrations:
Number tables and figures consecutively with Arabic numerals following their order in the text. Indicate the approximate location desired in the text. Give due regard to the proportions of the printed page. Do not put a period at the end of the table title. However, the tables and figures should be as simple and as few as possible. The same material should not normally be presented in tabular and graphical form. Coloured plates are unlikely to be accepted unless authors bear the cost. Diagrams should be drawn in black ink on white paper or card, or on stout tracing paper. High-quality (laser) computer-generated original figures are acceptable. Plan drawings for a reduction of 50% or more to a width of (preferably) one or two columns to minimize flaws.

Page charges:
Rs. 1000 and Rs. 4000 will be charged as membership fee and printing charges, respectively. In addition Rs. 500 per page will be charged for extra pages above the limit of 6 pages.

Offprints:
Ten offprint (reprints) are supplied free of charge.
