Hi Malakondaiah,

It is not possible to hide the Master field on the Page layout because it’s a required field in a master detail relationship .
But there is an option called "allow reparenting" at field setup of the master-detail custom field on the child object.
If it is unchecked, once the child record is created, it can't be edited and you can make it read only.

Please follow the below images:

Hi Malakondaiah,
Thanks for selecting my answer as a best answer.
When there is master detail relationship, it will automatically make mandatory field in master object and you can't Hide or Read Only this is mandatory field in edit page.
