Study Notes

Improvement in Food Resources

Food is essential for all living organisms, providing proteins, carbohydrates, fats, vitamins and minerals for growth and health.
Agriculture and animal husbandry are major food sources.
India's increasing population necessitates a significant increase in food production.
Existing agricultural land is intensively cultivated, limiting expansion.
Increased production efficiency for both crops and livestock is crucial.
The Green Revolution has led to increased grain production.
The White Revolution improved milk production.
Sustainable agricultural practices are needed to prevent environmental damage.
Food production alone is insufficient; ensuring access to food is also essential for combating hunger and malnutrition.
Improving incomes of agricultural workers is crucial.
Scientific farming techniques are vital for higher crop yields (e.g., mixed farming, intercropping).

Crop Improvement

Crop variety improvement focuses on identifying high-yielding varieties.
Hybridisation creates new varieties with desirable traits like disease resistance and high yields.
Genetic modification introduces beneficial genes.
Crop variety selection needs to consider factors like yield, quality, and resistance to biotic and abiotic stresses.
Short maturity durations optimize crop production in various climates and environments.
Uniform maturity facilitates easy harvesting.
Wider adaptability contributes to consistent production in diverse climates.

Crop Production Management

Different farming scales exist, varying in land, financial resources, and access to information and technologies.
Nutrient management is crucial for optimal crop growth.
Crop production levels range from 'no cost', 'low cost', to 'high cost' practices.
Crop protection against various pests and diseases is necessary to prevent crop loss.
Crop protection includes practices like weed removal, pesticide use, and pest control measures.

Animal Husbandry

Animal husbandry focuses on the scientific management of livestock for milk, meat, and labor.
Breeding and disease control are vital components of animal husbandry management.
Dietary needs and health are crucial concerns in animal husbandry.

Irrigation

Irrigation is crucial for crop success in regions with irregular rainfall patterns or insufficient rainfall.
Droughts pose a significant threat to agriculture, and varieties tolerant to drought conditions are crucial.
Crop varieties need to be chosen based on irrigation availability and water quality.

Bee-keeping

Bee-keeping (apiculture) yields honey and beeswax, a valuable agricultural enterprise.
Honey quality depends on the plants available (pasturage) for nectar and pollen collection.
Effective bee varieties are chosen for optimal honey production.

Fish Production

Fish (both marine and inland) are a significant source of protein.
Capture fishing and aquaculture (culture fisheries) are methods of fish production.
Composite fish culture (combining different fish species) enhances fish production.
Mariculture (culturing marine species) helps meet increasing fish demand.
Various fish breeds are used in aquaculture with appropriate water resources.

Other important points

Organic farming promotes sustainable agriculture by minimizing chemical inputs.
Manure and fertilizers are used to maintain soil fertility.
