Answer:

Explanation:

(c) Weeding

In a field many other undesirable plants may grow along with the crop. These undesirable plants are called weeds. Farmers use many ways to remove weeds. Methods to control weeds are: tilling before sowing of crops, physical removal of weeds by uprooting or cutting them close to the ground, using certain chemicals called weedicides etc.

(d) Threshing

Threshing is the process of separating grains or seeds from chaff. It is done after harvesting the crop. It is usually carried out with the help of a machine known as ‘Combine’. This machine is a combined harvester and thresher. It harvests plants as well as cleans grains.

Explanation:

C. Weeding refers to the removal of weeds. ... Primary weeding is done to clear huge amounts of plants, weeds ie with new agricultural fields or just after winter when the soil needs to be loosened anyway. (which is done with mechanized equipment)

D. Threshing is the process of loosening the edible part of grain (or other crop) 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.
