References and citations

Follow the style of the 7th edition of the American Psychological Association (APA)

The APA style is common in agricultural extension and is presented here. It should be noted that while APA style changes over time (see APA Website for latest information) Science publishers use variants that only approximate the current version. Depending on the style adopted or recommended by the publisher, institution/association or funding agency, the author must painstakingly maintain a high level of consistency. This can only be achieved through practice. The sample format below is taken from the 7th edition of APA Website. You should make a habit to always consult the website to guide your citations and referencing

Authorship provides credit for a researcher's contributions to a study and carries accountability. Each author is expected to have made substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data; or have drafted the work or substantively revised it. Also expected is to have approved the submitted version (and any substantially modified version that involves the author's contribution to the study); agreed both to be personally accountable for the author's own contributions and to ensure that questions related to the accuracy or integrity of any part of the work, even ones in which the author was not personally involved, are appropriately investigated, resolved, and the resolution documented.

JAE encourages collaboration with colleagues in the locations where the research is conducted, and expect their inclusion as co-authors when they fulfill all authorship criteria described above. Contributors who do not meet all criteria for authorship should be listed in the Acknowledgements section.
