What is the significance of 'crop protection' in maximizing agricultural yields? Describe two common methods of crop protection.

Crop protection is significant in maximizing agricultural yields because it safeguards crops from damage caused by pests (insects, rodents), diseases (fungi, bacteria, viruses), and weeds, all of which can significantly reduce quantity and quality of harvest. Without protection, a substantial portion of the crop can be lost. Two common methods are: 1) Chemical control: Using pesticides, insecticides, fungicides, and herbicides to kill or deter harmful organisms. This is effective but requires careful management. 2) Biological control: Utilizing natural enemies (predators, parasites) of pests to keep their populations in check. This is an environmentally friendly approach. Other methods include using resistant crop varieties and proper sanitation.
