Hide field when creating a node How can I hide a field when creating a node, but displaying it when editing a mode?
If I understand your question, I think that you can use a custom module (in this example, the name of the module is test_remove_field) and include the following code:

function test_remove_field_form_alter(&amp;$form, &amp;$form_state) {

    if (arg(0) == 'node' &amp;&amp; arg(1) == 'add') {
    $form['field_test']['#access'] = 0;
    }

}


Note: remember that field_test must be your respective field name.
