Study Notes
Crop Production and Management
- Food production must be large-scale to feed a large population
- Proper management and distribution are necessary
- People were nomadic until 10,000 BCE, moving for food
- They initially hunted and gathered, later cultivating crops like rice and wheat
- Cultivating the same type of plant on a large area is called a crop
- Crops are categorized as cereals, vegetables and fruits
- Crops are classified by the growing season (kharif or rabi)
- India has diverse climates, which affects crop types and growth
Agricultural Practices
- Preparation of Soil: Turning and loosening soil for root growth and aeration
- Sowing: Planting seeds in the soil
- Adding manure and fertilizer: Providing nutrients for plant growth
- Irrigation: Regular watering for crop growth
- Protection against weeds: Controlling unwanted plants that compete with crops
- Harvesting: Collecting mature crops
- Storage: Storing harvested crops properly
Agricultural Implements
- Plough: A tool used for tilling, adding fertilizers, removing weeds, and turning soil
- Hoe: A simple tool used to remove weeds and loosen the soil
- Cultivator: Tractor-driven implement used for ploughing; reduces manual work
Sowing
- Selection of quality seeds: Choosing good quality seeds for better yield
- Different methods for sowing seeds
Adding Manure and Fertilizers
- Manure and fertilizers provide essential nutrients to plants
- Continuous cultivation reduces soil fertility
- Manure: Organic matter from decomposition of plant or animal wastes.Improves soil texture
- Fertilizers: Chemical compounds rich in specific plant nutrients. Excessive use can harm soil.
Protecting Crops from Weeds
- Weeds compete with crops for resources and affect their growth
- Weeding: Removing weeds manually or using chemicals (weedicides)
- Weedicides should be used with caution
Harvesting
- Harvesting involves cutting mature crops
- Manual or machine-based harvesting methods
- Separating seeds from stalks
Storage
- Stored grains, if not properly stored can be prone to moisture, insects, rats, and microorganisms.
Food from Animals
- Animals provide food like milk, meat, egg etc.
- Fish provides cod liver oil rich in vitamin D
