Situation.

You enter a trough to make up bunch of homeruns in a trough...some are 120 v circuits and some are 277v circuits.

Is it code compliant to land 120v ground wires and 277v ground wires on the same ground bar in the trough?

Please share code reference for answers.
Thanks in advance!

First, it helps to use the correct terminology. Look up the definition in Art 100 of Ground. Your question is asking about the Equipment Grounding Conductor, check the definition of it, and now that you know what it is, Figure 250.1 takes you to Part VII, and there you will find 250.148

Mike Holt said it a simpler way "what color is it and what does it do"?
 
Not only is it compliant, it is most likely required to do so (or if separate bars are used, they need to be electrically connected).

I agree.

Now if OP is actually asking about interconnecting neutral conductors from each system that would not be acceptable. Depending on situations could allow for undesired current being possible on EGC's and other metallic components.
