Feed Your Mangoes Right! Quiz

Explore key principles of mango tree fertilization, including timing, nutrient needs, and common pitfalls, to promote healthy growth and abundant fruit yields.

  1. Best Fertilizer Application Time

    When is it most beneficial to apply fertilizer to mango trees to support flowering and fruit set?

    1. After harvesting the fruit
    2. In mid-winter when trees are dormant
    3. During peak summer heat
    4. Just before the rainy season begins

    Explanation: Applying fertilizer just before the rainy season provides nutrients at a crucial growth phase, supporting flowering and fruit set. Applying during peak summer or after harvest misses this active period. Fertilizing in mid-winter is less effective since growth slows during dormancy.

  2. Key Nutrient for Fruit Development

    Which primary nutrient is especially important for mango fruit development and size?

    1. Zinc
    2. Iron
    3. Calcium
    4. Potassium

    Explanation: Potassium plays a major role in fruit development and improving fruit size and quality. Calcium is important for cell structure, iron and zinc are vital micronutrients, but they are not the main nutrients driving fruit development in mangoes.

  3. Deficiency Signs in Mango Leaves

    Mango leaves showing yellowing between the veins (interveinal chlorosis) may indicate a deficiency of which nutrient?

    1. Boron
    2. Phosphorus
    3. Nitrogen
    4. Magnesium

    Explanation: Magnesium deficiency often causes interveinal chlorosis in leaves. Nitrogen deficiency typically results in overall pale or yellow plants, while boron and phosphorus deficiencies usually show other distinct symptoms rather than interveinal yellowing.

  4. Over-Fertilization Risks

    Which outcome is a likely risk of over-fertilizing mango trees with nitrogen-rich products?

    1. Increased resistance to pests
    2. Improved fruit sweetness
    3. Faster flowering
    4. Excessive vegetative growth with fewer fruits

    Explanation: Too much nitrogen tends to promote leaf and branch growth at the expense of flowering and fruiting. Improved sweetness and faster flowering are not typical results of over-fertilizing with nitrogen, and pest resistance may actually decrease due to weaker plant health.

  5. Organic vs. Chemical Fertilizers

    Which statement best describes a benefit of using well-rotted farmyard manure (organic fertilizer) for mango trees?

    1. It causes root burn more often than chemical fertilizers
    2. It immediately boosts fruit size
    3. It improves soil structure and microbial activity
    4. It makes the trees flower year-round

    Explanation: Organic fertilizers such as farmyard manure enrich soil structure and encourage beneficial microbes. They do not cause immediate increases in fruit size or year-round flowering, and they are less likely to cause root burn compared to chemical fertilizers.
