    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
