Key Topics to Revise
1
Sustainable Agriculture and Integrated Pest Management
- Sustainable agriculture means successful management of resources for agriculture to satisfy changing human needs while maintaining or improving environmental quality and conserving natural resources.
- It aims to increase food production without harming soil, water, forests, and other natural resources.
- Integrated Pest Management is a pest control approach that uses several different control methods together to keep pest populations below economically damaging levels.
2
Genetically Modified Organisms and Environmental Risks
- Genetically Modified Organisms are living organisms that have been genetically engineered by insertion of a foreign gene.
- The foreign gene is called a transgene.
- Transgenesis is achieved by injecting a gene from one organism into embryonic cells of another organism.
3
New Crop Strains: HYV and Hybrid Varieties
- High yielding varieties are crop varieties produced by manipulating the genes of crop plants to give desired characteristics such as high yield and pest resistance.
- High yielding varieties are produced through biotechnology.
- HYV seeds have a shorter lifecycle and support multiple cropping.
4
Mixed Cropping, Intercropping, Crop Rotation, Agroforestry and Polyculture
- Mixed cropping is also known as multiple cropping.
- Mixed cropping means growing one main crop and one or two subsidiary crops together on the same land.
