    • (c) weeding
    • (d) hybridisation
  2. 2. Decomposed organic matter added to soil is:

    • (b) pesticide
    • (c) weedicide
    • (d) fertiliser
  3. 3. Growing different crops in sequence on the same field is:
    • (a) crop rotation
    • (b) intercropping
    • (c) mixed cropping
    • (d) monoculture
  4. 4. Which crops naturally enrich the soil with nitrogen?

    • (b) fibre crops
    • (c) oilseeds
    • (d) cereals
  5. 5. What is intercropping?
  6. 6. Name two desirable traits sought in improved crop varieties.

View answers
  1. 1. (d) hybridisation — Hybridisation combines desirable traits.
  2. 2. (a) manure — Manure is decomposed organic matter.
  3. 3. (a) crop rotation — That is crop rotation.
  4. 4. (a) leguminous crops — Legumes host nitrogen-fixing bacteria.
  5. 5. Growing two or more crops simultaneously on the same field in a definite row pattern.
  6. 6. High yield and disease resistance (also early maturity, drought tolerance).
  7. 7. Crop production is improved through (1) crop variety improvement — developing high-yielding, disease-resistant varieties by hybridisation and selection; (2) crop production management — supplying nutrients via manure and fertilisers and water via irrigation, along with suitable cropping patterns; and (3) crop protection management — guarding crops against weeds, insect pests, diseases and storage losses.
