Guava Growth Boosters Quiz Quiz

Explore essential facts about successful guava cultivation methods, varieties, and growth requirements to enhance crop yields. This quiz covers fundamental practices and knowledge for effective guava farming.

1. Optimal Soil for Guava Cultivation

   Which type of soil is generally considered best for growing guava commercially for improved yield?

   1. Waterlogged peat soil
   2. Well-drained loamy soil
   3. Heavy clay soil
   4. Acidic sandy soil

   Explanation: Well-drained loamy soil allows proper root development and aeration, promoting healthy guava growth. Heavy clay soil holds excess water, which can cause root rot. Acidic sandy soil may lack nutrients needed by guava plants. Waterlogged peat soil retains too much moisture and impairs root respiration.

2. Guava Irrigation Frequency

   After establishment, how frequently should guava plants ideally be irrigated under normal conditions?

   1. Only during the rainy season
   2. Every day
   3. Every 7-10 days
   4. Once a month

   Explanation: Guava plants typically require irrigation every 7-10 days after establishment for optimal growth, especially in dry periods. Daily watering risks overwatering, while monthly irrigation may not provide adequate moisture. Irrigating only during the rainy season may result in drought stress during dry spells.

3. Preferred Propagation Method

   What is the most commonly used propagation method for producing quality guava plants?

   1. Air layering
   2. Tissue culture
   3. Cutting
   4. Direct seed sowing

   Explanation: Air layering is widely used for guava propagation because it preserves varietal traits and yields early-fruiting plants. Direct seed sowing may lead to variability in fruit quality, cuttings generally root poorly, and tissue culture is less common for guava and often limited to research settings.

4. Nutrient Deficiency Indicator

   Yellowing of guava leaves is most commonly an indicator of deficiency in which nutrient?

   1. Nitrogen
   2. Phosphorus
   3. Calcium
   4. Potassium

   Explanation: Nitrogen deficiency typically causes older guava leaves to turn yellow due to lack of chlorophyll. Phosphorus deficiency mostly affects root growth and may result in purplish leaves. Calcium deficiency often leads to blossom end rot, and potassium deficiency causes leaf edge browning rather than yellowing.

5. Ideal Planting Distance

   For optimum guava orchard management, what is the recommended planting distance between two guava plants in a line?

   1. 10 meters
   2. 2 meters
   3. 0.5 meters
   4. 6 meters

   Explanation: A 6-meter spacing is recommended to allow sufficient sunlight and air circulation for healthy guava growth. Planting at 2 meters or 0.5 meters can result in overcrowding and disease spread, while 10 meters is unnecessarily wide and reduces orchard productivity.
