Page 1: Introduction
India needs to increase food production to feed growing population.
Sources: crops (plant) and livestock/fisheries (animal).
Improvement through better management, varieties, and sustainable practices.
Page 2: Crop Production Improvement
Goals: higher yield, better quality, disease resistance.
Methods: nutrient management, irrigation, cropping patterns, crop protection.
Page 3: Nutrient Management
Macronutrients: N, P, K
Micronutrients: Fe, Mn, Zn, Cu, etc.
Manure (organic) vs Fertiliser (inorganic).
Advantages/disadvantages table.
Page 4: Irrigation
Sources: wells, canals, rivers, tanks, dams.
Methods: traditional vs modern (drip, sprinkler).
Advantages of modern: saves water, uniform.
Page 5: Cropping Patterns
- Mixed cropping
- Inter-cropping
- Crop rotation
Benefits: soil fertility, pest control, risk reduction.
Page 6: Crop Protection
Weeds, pests, diseases reduce yield.
Methods: weedicides, pesticides, insecticides, fungicides.
Biological control, resistant varieties.
Page 7: Crop Variety Improvement
Hybridisation, genetic modification.
Aims: higher yield, disease resistance, drought tolerance, shorter duration.
Page 8: Animal Husbandry
Rearing animals for food (milk, meat, egg) and work.
Cattle, poultry, fish, bees.
Page 9: Cattle Farming
Milch animals (milk) vs Draught (work).
Breeds: indigenous (Sahiwal) vs exotic (Jersey).
Cross-breeding for higher yield.
Management: shelter, feed, disease control.
Page 10: Poultry Farming
For egg and meat.
Broilers (meat) vs Layers (egg).
Cross-breeds for better quality.
Management: temperature, hygiene, vaccination.
Page 11: Fish Production
Marine (sea) vs Inland (freshwater).
Capture vs Culture fisheries.
Aquaculture, pisciculture, composite fish culture.
Page 12: Bee-Keeping (Apiculture)
For honey and wax.
Species: Apis mellifera, A. indica.
Management: hives, location, disease control.
Benefits: pollination + income.
Page 13: Sustainable Practices
Organic farming, integrated pest management.
Reduce chemical use, maintain soil health.
