The field name is not displayed.

Hello, could you please help me with how to display the field name? The field is called Article Number, and it only contains some digits. I want it to display as: Article Number: digits. The material type is called
dobavittovar, and the field type is field_articul. I placed the file node.tpl.php in the theme folder and also created the file node-dobavittovar.tpl.php, where I call the necessary fields. I call it like this - <?php print $node->field_articul[0]['view']; ?>, everything displays well, but without the field name, just the digits - and I would like to have it displayed again as - Article Number (field name) + some digits (the value of the field or whatever it's correctly referred to, probably the content of the field). In the field display settings, this field has a header at the top, and the summary is plain text.

It seems I've covered everything, what and how I'm doing
