In the European feudal system under manorialism what is the most significant economic commodity?

In the European feudal system under manorialism, the most significant economic commodity was land. Land was the basis of wealth and power, with lords owning large estates and peasants or serfs working the land in exchange for protection and sustenance. Agricultural production, particularly crops and livestock, was essential for sustaining the local economy and supporting the feudal hierarchy. This system created a self-sufficient economy centered around manors, where land and its agricultural output were paramount.
