Question

We use _________ to increase the yield of a crop. (pesticides/ fertilisers)

Answer 1

Fertilisers:

• Fertilisers are chemical substances that contain almost all the nutrients which increase crop production.
• Fertilisers contain potassium (K), nitrogen(N), and phosphorous (P) which contain all the nutrients which make the soil fertile and increase crop production.

Pesticides:

• Pesticides are the chemical substances that are used to kill the pests which destroy the crops.
• Commonly used pesticides are carbamate, organophosphate, etc.

Therefore, we use fertilisers to increase the yield of a crop.
