in order to get what I want

It isn't overly clear what you want. If you have a string with words separated by underscores and just want to return the last such word then you could do this:

my $row = 'We_need_feed';
my ($last) = $row =~ /[^_]*$/g;
print $last;

or you could split and then pop but maybe extracting the last isn't what you want at all.
