What is Harvesting?

This is the practice of collecting mature farm produce from the crop plant.

Harvesting can be done by hand, without the use of any tools. The removal of matured fruits from a tree plant by hand is termed plucking.

b. There will be a reduction in farmers’ income, which also leads to the spoilage of produce.

c. Late harvesting encourages over-ripening of fruits and also allows pest infestation.
