Is it possible to connect a USB keyboard to the arduino without a shield?

It depends on the Arduino and the USB keyboard. Many, but not all, USB keyboards have the ability to also work as a PS/2 keyboard. If your keyboard has this PS/2 capability, then you can connect it directly to any Arduino board and use one of the PS/2 Arduino libraries to read the keypresses (and, with some of the libraries, even control the lights on the keyboard). If the keyboard comes with a USB to PS/2 adapter, then it has this capability. Keyboards that don't come with the adapter may also…

Pare che si possa usare anche direttamente l'USB come fosse una PS/2, chiaramente non funzionerà con tutte le tastiere, ma vale la pena di provare.
