Potato

Potatoes are food items that can be planted, consumed raw, or cooked in a furnace to make baked potatoes.

Zombies
Zombies have a rare chance of dropping a potato when killed by the player.

Natural generation
Village farm plots have a 20% chance of being potatoes.

Farming
When farmed, potatoes will take 8 stages to grow. However, there are only 4 distinct textures, so only 4 visible stages: every two stages have the same texture, except that growth stage 7 keeps the same appearance as stages 5-6, so that only stage 8 has the final, 'mature' appearance.

Fully grown potato crops drop 1 to 4 potatoes (about 2.6 per crop harvested on average) and have a 2% chance of dropping an additional poisonous potato. Potato yield can be increased using a tool enchanted with fortune. Bone meal can be used to mature the potato to its last stage of growth.

Usage
To eat a potato, press and hold while a potato is selected in the hotbar. Eating a potato restores hunger and 0.6 hunger saturation.

In Pocket Edition, pigs will follow the player if they are holding a potato, and can be bred with them.

Trading
Villager farmers will buy 15-19 potatoes for an emerald as one of their initial tier trades.
