Potato

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

Zombies
Zombies have a 0.8% chance to drop 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 $2 5/7$ 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.

Potatoes must be directly planted on the top of a farmland block; unlike most blocks, targeting the side of a block which would result in it being placed in top of farmland will not allow it to be placed.

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

Breeding
Pigs will follow and can be bred by a player holding a potato.

Villagers can pick up potato items to become willing, which will allow them to breed. Villagers require 12 potatoes to become willing.

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

Composting
Placing a potato into a composter has a 65% chance of raising the compost level by 1.
