Can we cite/use publications from other disciplines?
As I have previously said in an answer to another question on this site, research is about telling the truth about facts of reality.  You can cite any fact of reality you want, from any source.  If you want to cite sources from other disciplines that is absolutely fine.  You can cite papers from any discipline.  You can cite a published academic paper, a newspaper article, a blog post, a letter, a tweet, the conditions written on the back of a bus-pass, or the graffiti written on the wall of the faculty toilets.  Any source of information that is relevant to your paper is fine.  So long as cited information advances your work, and you specify the source, and accurately transcribe the remarks, that is okay.

Generally academics stick mostly to citing peer-reviewed research appearing in academic journals so that they are dealing with reliable information.  Cross-disciplinary research frequently cites work from across disciplinary boundaries.  The main thing you will want to do to make sure your work is acceptable is to do your literature review well, and make sure you are citing relevant work that bears on your results.  You are unlikely to get a rejection for citing work that the referee hadn't thought of.  It is more likely you will get a rejection for failing to mention relevant published work that bears on your argument that the referee wants you to add.  For that reason, cross-disciplinary research generally requires citations from multiple fields.
