My problem is that I needed to use put method, and for that I needed to use HTTP::Request The following solutions works: 
    my $uri=$reqUri;
    local $data='{ "update": { "comment": [ {"add":{"body":"new commen
+t via rest and LWP"} } ] } }';
    local $ua, $key, %form, $response;

    $ua = LWP::UserAgent->new;
    $ua->timeout(10);
    $ua->agent("citrigger");
    my $request = HTTP::Request->new(PUT => $uri);
    $request->header(Authorization => 'Basic ' . encode_base64($usr . 
+':' . $pwd));
    $request->content_type('application/json');
    $request->content($data);
    $response = $ua->request($request);
    if ($response->is_success) {
        $responseTxt=$response->decoded_content;
        print "\nResponse:\n$responseTxt\n";
    }
    else {
        die $response->status_line;
    }
    return;
