Yes, -P ensures that long lines are not split.
And -h is "human readable", here you need the opposite.

You can strip a trailing % also in awk (with the sub function), or with a shell variable modifier.

` ` can cause a head ache with quoting (in addition to ssh). Get used to $( )!
Code:
FS=$(ssh -nx "user1@$i" "df -kP ." | awk 'NR>1 {print $5}')
FS=${FS%\%}

The % character after the % modifier must be quoted to not conflict with the %% modifier.

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for hostbased authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
     HostbasedAuthentication to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about hostbased authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
	     authentication is used.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

AUTHORS

     Markus Friedl <markus@openbsd.org>

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
