Study Notes
Farming Practices
- Farming is divided into three stages: seed selection, nurturing crop plants, and crop protection.
- Major activities to improve crop yields include crop variety improvement, crop production improvement, and crop protection management.
Crop Variety Improvement
- Focuses on selecting high-yield crop varieties through breeding for traits like disease resistance and fertilizer response.
- Hybridization is a technique used for crossing genetically dissimilar plants to create desirable crop varieties.
Organic Farming
- Uses minimal to no chemicals, relying primarily on organic manures and recycled farm waste for fertilization.
- Implements bio-agents such as blue-green algae for biofertilizers and neem leaves for bio-pesticides.
Irrigation Methods
- India’s agriculture largely depends on monsoon rains; timely irrigation is crucial for crop success.
- Common irrigation systems include:
- Tube Wells: Tap deeper water strata using pumps.
- Canals: Distribute water from reservoirs or rivers through a network of branches.
- River Lift Systems: Draw water directly from rivers when canal flow is insufficient.
- Tanks: Store run-off water from smaller catchment areas.
Nutritional Values of Animal Products
- Milk: 3.6% fat, 4% protein, contains vitamins B1, B2, B12, D, and E.
- Eggs: 12% fat, 13% protein, contains vitamins B2 and D.
- Meat: 3.6% fat, 21.1% protein, contains vitamins B2 and B12.
- Fish: 2.5% fat, 19% protein, contains niacin, D, and A.
Animal Husbandry
- Scientific management of livestock including feeding, breeding, and disease control.
- Rising demand for animal products like milk, eggs, and meat due to population growth and increased living standards.
Fish Production
- Fish serves as an economical source of animal protein; includes finned fish and shellfish.
- Obtaining fish can occur through capture fishing (natural resources) or culture fishery (fish farming).
- Composite fish culture uses multiple species that do not compete for food, enhancing pond productivity.
Bee-Keeping
- An essential agricultural activity for honey production, requiring low investment from farmers.
- The quality of honey is influenced by the type of flowers available for bees, affecting flavor and nutrients.
- Italian bees are favored for commercial honey production due to high honey collection rates and lower aggression.
