STYLE MANUAL FOR THE JOURNAL OF AGRICULTURE
OF THE UNIVERSITY OF PUERTO RICO (JAUPR) 

Issued by the Agricultural Experiment Station of the University of Puerto Rico

Mayagüez Campus for the publication of papers and research notes, in English or

Spanish by staff members or others, dealing with scientific agriculture in Puerto Rico

and elsewhere in the Caribbean Basin and Latin America.

1.  Title: Begin with a significant word or phrase (i.e., eliminate words such as “study,” “effects of”); be specific; mention contribution of research.  Try to limit number of characters to 80 or fewer, including spaces.  Include calls for footnote 1 (date of submission) and 2 (acknowledgments).

2.  Authors: Authors’ full names --first name and last name-- must appear on title page below title, each author with call for footnote identification.  If both last names are used, join them with hyphen, e.g., Ismael Pérez-Rodríguez.  In a research note, note or germplasm and cultivar release the authors’ names appear exactly as in a full paper.

3.  Abstract: Explain in one paragraph, no longer than 200 words, importance of the work, objective, scope and procedures.  Emphasize results and conclusions.  An informative abstract is preferable to a merely descriptive one.  Preferably do not use acronyms; if you do explain them.  Make no references.  Use no calls for footnotes.

4.  Key words: Furnish key words in English ^__ no more than five ^__ for computer retrieval and abstract indexes.  Follows Abstract.

5.  ‘Resumen’: Each paper in English must be accompanied by its own abstract in English plus an abstract (‘resumen’) in Spanish, with its title in Spanish, and followed with ‘Palabras clave’ (key words) in Spanish.  This ‘resumen’ should not exceed 250 words.  It follows key words section.  For a paper in Spanish, the author must submit an English language abstract (with title in English), which follows ‘resumen’.

6.  Introduction: Explain scope of problem.  Present the main point early in the introduction.  Explain objectives, focus, and justification for present work in the context of previous research.

7.  Materials and Methods: The author must include in the Materials and Methods section, along with specifications of all materials and names of all methods and techniques, information with regard to the design of the experiment and the statistical methods used for the analysis of the data.  The information should be presented in a way that allows other scientists to judge the validity of the study and allows them to use it as a basis for further experiments.  The plot size, sample size, number of replications, statistical design, the environmental variables (field or laboratory conditions) and a measure of the precision achieved should be reported.  References should be cited for all non-standard experimental designs.

8.  Results: Write scrupulously what was found.  A good results section with clear tables and figures saves discussion space.

9.  Discussion: Highlight major findings and relate them first to the objectives of the work and then to previous research.  Analyze implications of results.  Include conclusions in the discussion.  Write conclusions in last paragraph of discussion section on the basis of results.  Indicate significance of conclusions; indicate future work needed on the basis of conclusions.  In JAUPR, results and discussion are usually combined.

10.  Literature Cited: In JAUPR manuscripts, this section appears immediately after the Results and Discussion section, before tables, figures, and captions for figures on their separate sheets.  Verify that all literature listed has been cited.  Only literature already published or accepted for publication appears in a reference list.  In the text of manuscripts as well as in research notes, notes and germplasm and cultivar releases, JAUPR uses the name-and-date system, also called the Harvard system  ^__author, year, e.g.,  (O’Hallorans et al., 1993).

11. Footnotes: May be submitted on a separate page.  Footnote 1 should read “Manuscript submitted to Editorial Board on day-month-year (e.g., 1 June 1999).” Acknowledgments (optional) appear in footnote 2.  These may include funding information, lab personnel, and other help.  Footnotes 3 and following are for identification of authors.  State position, institution and address of each author separately.
