Potato

A potato is a food item that can be planted, consumed raw, or cooked in a furnace or a campfire to make baked potatoes.

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

Fully grown potato crops drop 1 to 5 potatoes (about 3 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, with Fortune III harvesting an average of 5.3 potatoes. Bone meal can be used to mature the potato to its last stage of growth.

The yield is calculated by a binomial distribution: 2 drops are fixed, then a drop is attempted three times with a success rate of around 57% to yield the extra 0–3 drops. Each level of Fortune enchantment increases the number of attempts by one.

Mob loot
Zombies, husks, and zombie villagers have a 2.5% chance of dropping either an iron ingot, carrot, or potato when killed by a player or tamed wolf. This is increased by 1% per level of looting. This gives potatoes the following chances of dropping:
 * $1/120$ (about 0.83%)
 * $11/600$ (about 1.83%) with Looting I
 * $17/600$ (about 2.83%) with Looting II
 * $23/600$ (about 3.83%) with Looting III

Farming
When farmed, potatoes require 8 stages to grow. However, there are four visible stages due to having only four distinct textures: 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.

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 follow and can be bred by a player holding a potato.

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

Trading
Novice-level farmer villagers have a 25% or 40% chance to buy 26 potatoes for an emerald as part of their trade.

Composting
Placing a potato into a composter has a 65% chance of raising the compost level by 1. This is less efficient than composting with baked potatoes, which has a higher success chance of 85%.
