Question

How do biotic and abiotic factors affect crop production?

Answer 1

Biotic factors such as pests, insects and diseases reduce the crop production. A pest causes damage to our crops by feeding. Weeds also reduce crop productivity by competing with the main crop for nutrients and light.

Similarly, abiotic factors such as temperature, wind, rain etc. affect the net crop production. For exampledroughts and floods have a great impact on crops sometimes, destroying the entire crop.
Both biotic and abiotic factors affect crop production in following ways
1.Poor germination ability
2.Infection of insects
3.Weight loss
4.Discolouration
