Study Notes
Food Resources
- All living organisms require food, including proteins, carbohydrates, fats, vitamins, and minerals.
- Both plants and animals are major food sources.
- Efforts are continually made to improve agricultural and animal husbandry practices to increase food production to accommodate growing populations.
- India's large and growing population requires significant grain production increases.
- Intensified farming is necessary due to limited arable land.
- Sustainable practices in agriculture and animal husbandry are essential to maintain environmental balance.
- Food security depends on both availability and affordability of food.
- Increasing farmer incomes supports food security.
- Scientific management practices, mixed farming, intercropping, and integrated farming (combining agriculture with livestock, poultry, or fisheries) can increase production.
Crop Improvement
- Crop yield improvement involves three stages:
- Selecting high-yielding seeds.
- Nurturing crop plants effectively.
- Protecting crops from damage.
- Crop variety improvement focuses on creating higher-yielding, disease-resistant, and quality varieties through breeding and genetic modification.
- Hybridisation creates genetically dissimilar plant varieties.
- Genetically modified organisms (GMOs) include genes that provide desired characteristics to improve yield.
Crop Production Management
- Crop production management utilizes various approaches for high yield and efficiency, including different types of farming.
- Correct nutrient management and application are crucial in maintaining soil fertility.
- Macronutrients (required in large quantities) include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
- Micronutrients (required in smaller amounts) include iron, manganese, boron, zinc, copper, molybdenum, and chlorine.
- Soil, water, and air are the main sources of plant nutrients.
- Manure supplies organic matter and nutrients, while fertilizers supply essential macronutrients.
- Sustainable approaches include crop rotation and intercropping to maintain soil fertility and balance.
Crop Protection Management
- Field crops are exposed to weeds, insect pests, and diseases.
- Weed control includes mechanical removal and preventive methods like crop rotation and timely sowing.
- Insect and disease control methods include using insecticides and fungicides.
Irrigation
- India's agriculture is primarily rain-fed.
- Irrigation is essential to boost yields from various water sources like wells, canals, rivers, and tanks.
- Different irrigation methods are used based on available water resources.
- Rainwater harvesting and watershed management are crucial to increase water availability.
Cropping Patterns
- Mixed cropping involves growing two or more crops simultaneously on the same land.
- Intercropping involves growing two or more crops in a pre-planned succession (in alternating rows).
- Crop rotation is growing different crops in a pre-planned sequence to maintain soil fertility and reduce pest and disease outbreaks.
Animal Husbandry
- Animal husbandry involves scientific management of animals such as livestock, including feeding, breeding, and disease management.
- Milk and meat demands increase with population growth.
- Improving livestock breeds, including their care, is important.
- Cattle are important for milk production and farm labor (draught animals).
- Poultry (chickens and ducks) are raised for meat or egg production, depending on the breed.
- Honey production comes from beekeeping. Beekeeping is a source of honey and wax.
Fish Production
- Fish are a significant source of protein.
- Fish is obtained through capture fishing, mariculture, and aquaculture.
- Fish farming techniques utilize both marine and freshwater environments.
- Composite fish culture practices involve growing different fish species together in a single body of water to maximize resource utilization.
