Question

What is weeding,threshing&harvesting?

Answer 1

Weeding:-Weeding is an important control method practiced in many crops. The removal of weeds is useful because these unwanted plants compete with the crop for space, water and nutrients.

Weeding should usually be done in an early crop stage, as this is more practical (the weed plants are smaller) and more effective. Often, the weeding has to be repeated 2 or 3 times, whenever weeds start to grow again.

Threshing:-Threshing is the process of loosening the edible part of cereal grain (or other crop) from the scaly, inedible chaff that surrounds it. It is the step in grain preparation after harvesting and before winnowing, which separates the loosened chaff from the grain. Threshing does not remove the bran from the grain.

Harvesting:-Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using ascythe, sickle, or reaper
