Mastering Mango Nutrients Quiz Quiz

Challenge your understanding of optimal mango tree fertilization, nutrient management, and growth factors in horticultural practices. Ideal for students and enthusiasts aiming to boost their mango cultivation knowledge.

  1. Best Fertilizer Application Timing

    At which growth stage is mango fertilization most critical for promoting fruit set and yield improvement?

    1. Immediately before flowering
    2. At full fruit maturity
    3. Right after harvest
    4. During dormancy

    Explanation: Fertilizing just before flowering supports the energy demands of fruit set and early development. During dormancy, nutrient uptake is minimal, so fertilizer is less effective. Post-harvest fertilization mainly supports next year's growth, not current yield. At full fruit maturity, the benefits for yield are already past.

  2. Key Nutrient for Mango Growth

    Which primary nutrient is most crucial for robust vegetative growth in mango trees?

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

    Explanation: Nitrogen drives leafy, vegetative growth and is essential for overall vigor. Zinc is important for fruit set and quality but not primary growth. Magnesium is vital for chlorophyll but not as directly significant as nitrogen here. Boron supports reproductive stages rather than vegetative growth.

  3. Micronutrient Deficiency Symptom

    Yellowing of young mango leaves with stunted growth is often a sign of deficiency in which micronutrient?

    1. Sulphur
    2. Zinc
    3. Copper
    4. Potassium

    Explanation: Zinc deficiency typically causes leaf yellowing and growth suppression in mango. Potassium and sulphur deficiencies show different symptoms, such as marginal leaf burn or uniform chlorosis. Copper deficiency is rarer and presents differently.

  4. Organic Manure Role

    What is one key benefit of applying well-decomposed farmyard manure to mango orchards?

    1. Directly increases fruit sugar content
    2. Eliminates all pest risks
    3. Improves soil structure and nutrient availability
    4. Speeds up flowering regardless of season

    Explanation: Well-decomposed manure enhances soil physical properties and provides a slow release of nutrients. It does not directly alter fruit sugar, eliminate pests entirely, or override seasonal flowering cues.

  5. Over-Fertilization Consequence

    What can excessive application of nitrogen fertilizer cause in mango trees?

    1. Excessive vegetative growth at the expense of fruiting
    2. Complete pest resistance
    3. Enhanced fruit sweetness
    4. Uniform flowering each year

    Explanation: Too much nitrogen causes lush foliage growth but can decrease flowering and fruit set. It does not improve fruit sweetness, pest resistance, or guarantee even flowering, which depend on other factors.
