Study Notes

Improving Food Resources

Global population growth necessitates increased food production.
Malnutrition remains a significant concern for many.
Sustainable agriculture is key, emphasizing resource optimization and minimizing environmental impact.

Crop Improvement

Plant breeding enhances crop quality and yield.
Desirable traits include higher yield, improved quality, resistance to biotic and abiotic stresses, shorter maturity, and wider adaptability.
Hybridisation combines desirable traits from different parental plants.
Genetic engineering (GM crops) introduces beneficial genes, though debated for safety and environmental impact.
Government and research initiatives develop and disseminate improved crop varieties.

Crop Production Management

Nutrient management is vital for plant growth.
- Manures (compost, vermicompost, green manure) provide organic nutrients.
- Fertilizers (chemicals) provide essential nutrients but can have negative environmental effects if overused.
Efficient water management is crucial for crop irrigation.
- Modern techniques (drip and sprinkler irrigation) conserve water.
Cropping patterns like mixed cropping, intercropping, and crop rotation optimize yield and manage pest problems.
Pest and disease control employs diverse strategies.
- Pesticides can harm the environment and promote pesticide resistance.
- Biopesticides offer natural pest control alternatives.
- Integrated Pest Management (IPM) combines various pest control approaches.
Proper storage prevents post-harvest losses due to pests and spoilage.

Animal Husbandry

Animal husbandry encompasses breeding, feeding, and caring for animals.
- Cattle farming includes dairy (high milk-producing) and draught (work animals) breeds.
- Poultry farming focuses on breeds for eggs (layers) or meat (broilers).
- Fish production includes capture fisheries and aquaculture (pond/sea).
- Bee-keeping (apiculture) is an integral part.
Animal breeding aims to improve traits like milk production, meat quality, and disease resistance.
Nutritional feed and disease control are crucial for animal productivity and health.

Sustainable Agricultural Practices

Organic farming avoids chemical inputs, prioritizing natural methods.
Integrated farming systems combine multiple agricultural practices (crops, livestock, fish).
Efficient water management aids in irrigation using practices like drip irrigation and rainwater harvesting.
Soil health management through practices like crop rotation and manure use enhances soil fertility.

Conclusion

Sustainable food production strategies are essential for global food security.
A balanced approach to improving yields and maintaining environmental health is vital.
