How to place an link of "application manager" on the home screen? I'm going many times daily to Application manager in Settings.

(Android 4.2.2:)
Settings --> More --> Application manager

Is it possible to put a link of "Application Manager" on the Home screen in order to avoid passing by Settings?
(I don't want to install external application managers apps)
That should be possible using a shortcut to the corresponding activity. Launchers like Apex have that feature built-in, for others you can use helpers like Activity Launcher. Both allow you to browse your apps, dive into their activities, and chose one to create a shortcut for. In your case, you would need to investigate the Settings app – and I'm pretty sure you'll find the matching activity.

Edit: Just in case you might miss that as well, you'll have to tap the entry of the app in question (here: Settings) to open the list of its activities.
