Which agricultural practice involves growing different crops together on the same land at the same time?

  1. Monoculture

  2. Intercropping

  3. Crop Rotation

  4. Agroforestry


Correct Option: B
Explanation:

Intercropping is an agricultural practice that involves growing different crops together on the same land at the same time. This practice helps improve soil fertility, control pests and diseases, and reduce the risk of crop failure. Intercropping also promotes biodiversity and provides habitat for beneficial insects and wildlife.

What is the term used to describe the process of introducing trees and shrubs into agricultural systems?

  1. Deforestation

  2. Reforestation

  3. Afforestation

  4. Agroforestry


Correct Option: D
Explanation:

Agroforestry is the practice of introducing trees and shrubs into agricultural systems. This practice can provide a number of benefits, including improved soil fertility, reduced erosion, increased biodiversity, and additional sources of income for farmers. Agroforestry systems can also help mitigate climate change by sequestering carbon dioxide from the atmosphere.

Which agricultural practice involves the use of synthetic fertilizers and pesticides to increase crop yields?

  1. Organic Farming
