The Potato is a farmable food item that is used as a source of nutrition in Minecraft. It is one of six crops that are required to be grown on farmland blocks. They are a food item that can be used for breeding pigs and they were added to Minecraft in v1.4.2 in the ‘Pretty Scary Update’. They are a renewable resource, meaning you can make a farm out of them with just a single potato.

Farming
Potatoes can be farmed by planting them on farmland. Planted potatoes go through 8 stages to grow completely, and go through 4 visually distinct stages. When harvested, you will be able to collect between 2-5 potatoes per crop. Their growth can be accelerated with bone meal.

Potatoes can be smelted in furnaces and smokers to make baked potatoes which provide more nutrition than regular potatoes.
