Minecraft, how do I get potatoes from normal zombies (PE)?

I always tried to kill zombies, but they never dropped potatoes… Do I have to do anything? (Sword, hand…)

Is very rare that the potatoes drop.

You really don't have to pay attention to anything.

If you increase the probability, it will be faster. So try looting 3 swords.

Otherwise you can also try to face a spawner, because of course you can kill more zombies in a short time.

Looting, if there's one on the phone… Last time I played the lite with the nether Reactor core: ^) Otherwise just kill a lot
