Minecraft wiki entry for Crop_farming, associated text: Each crop requires a seed for planting, and getting the first few can be non-trivial. After the first few seeds, or the first carrot or potato are planted, they eventually produce more seeds or vegetables than you started with. These can be used to replant, and plant more empty spots, until you've filled your farm. All four crops provide food for the player, and also to breed various farm animals. In addition to the sources listed below, all four crops can be found in village farms, and sometimes in village chests.
