There is a block in lib/tpl/dokuwiki/tpl_header.php:

        // display logo and wiki title in a link to the home page
        tpl_link(
            wl(),
            '<img src="'.$logo.'" '.$logoSize[3].' alt="" /> <span>'.$conf['title'].'</span>',
            'accesskey="h" title="[H]"'
        );
Remove <span>'.$conf['title'].'</span> from it.

Each update of Dokuwiki engine will overwrite this change. You'll need to repeat it manually after each update or copy paste doku template into a new one and update this new template manually.
