How not to show leave a Reply to Home Page?

Follow these steps:

1. Go to ‘Pages’.
2. Look for the page you’ve set as your homepage in the list.
3. Hover your cursor over the title and click on ‘Quick Edit’.
4. Uncheck ‘Allow Comments’ and then ‘Update’.

Edit:
For disabling Trackbacks and Pingbacks (and Comments too!):

1. Open the page you’ve set as your homepage for editing.
2. Look for a box titled ‘Discussion’, and uncheck ‘Allow Pingbacks and Trackbacks on this page’.
3. If the ‘Discussion’ box is not visible on the edit page, then click on the ‘Screen Options’ button which is at the very top (near ‘Howdy Admin’). Select ‘Discussion’ from the panel.
4. Now repeat step 2.

Hope this helps! If it’s not clear, please let me know, I’ll put a screen shot.
