Fennel Facts Quiz Quiz

Explore essential knowledge on fennel cultivation in horticulture, including planting, soil needs, growth stages, and harvesting practices. Ideal for those interested in basic agricultural techniques related to fennel.

  1. Optimal Soil for Fennel

    Which type of soil is considered most suitable for planting fennel in a horticultural setting?

    1. Acidic peat soil
    2. Saline soil
    3. Heavy clay soil
    4. Loamy, well-drained soil

    Explanation: Loamy, well-drained soil holds enough moisture but also allows excess water to drain away, which is ideal for healthy fennel growth. Heavy clay soil retains too much water and can cause root rot. Saline soil may hinder fennel growth due to salt stress. Acidic peat soil is often too acidic and not preferred for fennel cultivation.

  2. Fennel Sowing Season

    During which season is fennel typically sown in most temperate regions for optimal growth?

    1. Early spring
    2. Late autumn
    3. Mid-winter
    4. Peak summer

    Explanation: Fennel is best sown in early spring as the soil starts to warm, promoting healthy seed germination. Mid-winter is too cold for proper growth, late autumn does not provide enough time before frost, and peak summer may stress young plants due to heat.

  3. Fennel Spacing Guidelines

    When cultivating fennel for bulbs, what is the recommended spacing between individual plants?

    1. 5-10 cm
    2. 90-100 cm
    3. 50-60 cm
    4. 25-30 cm

    Explanation: Spacing fennel plants 25-30 cm apart allows for proper bulb development and air circulation. 5-10 cm is too crowded for bulb formation, while 50-60 cm and 90-100 cm spacing waste growing area and are more suited to larger crops.

  4. Watering Requirements

    What is the recommended irrigation approach for fennel during the growing season?

    1. Only water at planting
    2. Daily overwatering
    3. Regular moderate watering
    4. No irrigation needed

    Explanation: Fennel thrives with consistent, moderate watering throughout its growth, keeping soil slightly moist. Daily overwatering can cause root diseases, no irrigation can lead to drought stress, and watering only at planting is insufficient for development.

  5. Harvest Time Identification

    How can you tell when fennel bulbs are ready for harvest in the field?

    1. Swollen bulbs above soil level
    2. Leaves turn completely yellow
    3. Bulbs sink below soil surface
    4. Only flowers are present

    Explanation: Fennel bulbs are ready to harvest when they appear swollen and visible above the soil. Yellowing leaves typically indicate aging or stress, bulbs do not sink below the soil when ready, and the presence of only flowers means harvest opportunities may have been missed.
