Study Notes

Crop Care and Maintenance Practices

  • Cultivation:

    • The first stage of crop production involves soil stirring (e.g., plowing, harrowing).
    • Effective for weed and pest control.
    • Loosens soil, improving root aeration.
    • Conventional tillage is a common method.
    • Reduced or no-tillage can increase soil carbon levels, benefiting soil health and yields.
  • Seed Sowing/Planting Seedlings:

    • High-quality seeds/seedlings are essential.
    • Seeds should be planted at a depth of 1.5 to 2 inches to ensure proper moisture.
    • Proper spacing is critical for optimal plant growth.
  • Irrigation:

    • Crops need water, especially during droughts.
    • Water requirements vary based on crop type.
    • Irrigation methods include manual, drip, and sprinkler.
    • Manual irrigation is labor-intensive and time-consuming.
    • Drip irrigation is efficient, delivering water and nutrients directly to plants.
    • Sprinkler irrigation uses spray, often advantageous with water scarcity.
    • Soil and plant factors impact irrigation needs.
  • Fertilizer Application:

    • Nutrient-deficient soil needs enrichment through fertilizers, manures, or compost.
    • Fertilizer application methods include scattering or mixing with the soil before planting.
