Marvels of Mushroom Growing Quiz

Explore the essentials of mushroom cultivation in horticulture, covering types, growth conditions, and basic techniques. Discover how edible fungi are thoughtfully grown as a valuable agricultural crop.

  1. Ideal Growing Medium

    Which material is most commonly used as the growing substrate for cultivating button mushrooms in horticultural practice?

    1. Composted straw and manure
    2. Clay pebbles
    3. Sandy soil
    4. Pine bark mulch

    Explanation: Composted straw and manure provide rich nutrients and retain moisture, creating a favorable environment for button mushrooms. Sandy soil lacks nutrients and moisture-retention. Clay pebbles are used more in hydroponics than traditional mushroom farming. Pine bark mulch is not typically suitable for button mushroom growth.

  2. Mushroom Species Selection

    Which species is most widely cultivated for commercial production due to its popularity and ease of growth?

    1. Agaricus bisporus
    2. Amanita muscaria
    3. Ganoderma lucidum
    4. Chaga

    Explanation: Agaricus bisporus, known as the button mushroom, is favored for commercial cultivation due to its popularity and manageability. Amanita muscaria is toxic and not grown for food. Ganoderma lucidum is cultivated mainly for medicinal use, not food. Chaga is wild-harvested from birch trees and less commonly cultivated.

  3. Environmental Requirements

    What is the most crucial factor to control when fruiting mushrooms for a successful harvest?

    1. High wind
    2. Full sunlight
    3. Dry air
    4. Humidity

    Explanation: High humidity is essential for mushroom fruiting, as it prevents drying and supports development. Full sunlight can damage developing mushrooms. Dry air would desiccate them, while high wind typically reduces humidity and can cause drying.

  4. Sterilization Importance

    Why is sterilizing or pasteurizing the substrate important before inoculating mushroom spawn?

    1. To increase yield instantly
    2. To remove competing organisms
    3. To speed up harvest
    4. To brighten the mushroom caps

    Explanation: Sterilization eliminates bacteria, molds, and other fungi that could compete with or harm the mushroom crop. It doesn't directly speed up the harvest, instantly increase yields, or change mushroom coloration.

  5. Harvest Timing

    When is the optimal time to harvest most cultivated mushrooms to ensure best texture and shelf life?

    1. When the stem turns yellow
    2. After ten days regardless of growth
    3. Before caps fully open
    4. After full spore release

    Explanation: Harvesting mushrooms just before the caps fully open ensures ideal texture, flavor, and storage. After spore release, mushrooms become softer and less marketable. Yellowing stems may indicate over-maturity, and harvest timing should be based on growth, not a fixed number of days.
