Harvesting.
- In this process the crops are cut for, gathering ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season.
Winnowing
- to free the grains from the lighter particles of chaff, dirt, etc., especially by throwing it into the air and allowing the wind or a forced current of air to blow away impurities. mostly a fan or winnowing machine (that has a fan inside) is used for it
- sometimes naturally blowing winds is also helpful..
Threshing
- separate grain from (corn or other crops), typically with a flail or by the action of a revolving mechanism.
- Threshing is the process of loosening the edible part of grain (or other crop) from the chaff to which it is attached. It is the step in grain preparation after reaping. ... Threshing may be done by beating the grain using a flail on a threshing floor.
- In this process the harvested crop , separates its grassy portion and grains
Harvesting → Threshing → Winnowing→ storage,further sales and uses....
