What is the term used for separating grains from the stalks of a harvested crop?

Threshing is the process of separating the grains from the stalks of a harvested crop. This can be done manually by beating the crop using a stick or mechanically using a machine called a thresher.

After the threshing process, the grain and straw mixture is further processed by winnowing, which separates the grain from the straw and other debris. Weeding, on the other hand, is the process of removing unwanted plants (weeds) from the crop. Harvesting involves cutting and gathering the mature crop.
