Answers
Answer:
Harvesting-Cutting of crop plants after maturation is called harvesting. It is done by cutting the crop plants close to the ground or pulling the crop plants. Threshing-Separation of grains from chaff is called threshing. Winnowing-Separation of grains from chaff by the help of wind is called winnowing.
Answer:
(a) Harvesting is the process of gathering a 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.
(b) Threshing is the process of loosening the edible part of grain from the straw to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain. Threshing may be done by beating the grain using a flail on a threshing floor.
