Minecraft wiki entry for Trading, associated text: The main use of this profession is to obtain emeralds by trading away crops, as well as buying golden carrots and glistering melon slices without having to craft them using gold. It is recommended to sell pumpkins, as these grow fast and are easy to mass farm. However, level them up with the melon trade, as it gives twice as much experience to the villager than the pumpkin trade.
