Use a tab control or seperate layouts.
Would I be correct that you are looking at your layout in table view?
If so, there's a specific limit to how wide your table can be. You can squeeze in a few more fields by making the columns narrower, but in all practicality, you'll need to think in terms of several layouts each with a sub set of the total number of fields and nav buttons in the header for changing layouts to see the rest of the data.
But 50+ fields on one layout also raises the possibility that you may need to reconsider the design of your underlying data model.
