Regarding Production Of Witnesses In A Trial

Is it compulsory/necessary that the evidences (like audio/video recordings, text messages etc.,) or reports or plaintiff side's witnesses, if any, that the plaintiff relies upon be submitted at (or immediately after) his/her examination-in-chief? Can they (evidences/witnesses/reports) be submitted at a later stage when it necessitates? Say for eg., can we submit or produce them during/after the defendant's/respondent's cross-examination based on their deposition, if the need arises? (Civil/Tribunal Case)
