Crack the Cabbage Code Quiz Quiz

Explore essential facts about cabbage cultivation, from soil requirements to harvesting tips. Test your knowledge on best practices and common challenges in growing healthy cabbage crops.

1. Optimal Soil pH for Cabbage

   What is the preferred soil pH range for optimal cabbage growth in horticulture?

   1. 4.0–4.5
   2. 5.0–5.2
   3. 7.5–8.0
   4. 6.0–6.5

   Explanation: Cabbage grows best in slightly acidic to neutral soils with a pH of 6.0–6.5, ensuring nutrient availability and healthy development. A pH of 4.0–4.5 is too acidic and may cause nutrient deficiencies. 7.5–8.0 is overly alkaline and less suitable for cabbage. 5.0–5.2 is more acidic than recommended and can hinder growth.

2. Ideal Planting Time for Cabbage

   When is the most suitable season for planting cabbage in temperate climates?

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

   Explanation: Early spring provides cool conditions optimal for cabbage development, minimizing heat stress and pest pressure. Mid-summer temperatures are usually too high and can cause bolting. Late autumn may not allow enough time before frost. Peak winter is often too cold for seedling survival and growth.

3. Nutrient Deficiency Symptoms in Cabbage

   If cabbage leaves turn purple, which nutrient is most likely deficient?

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

   Explanation: Purple coloration in cabbage leaves often signals phosphorus deficiency due to its role in energy transfer. Potassium deficiency usually causes leaf edge scorch. Nitrogen shortages typically show as general yellowing. Calcium lack leads to tip burn rather than purple coloring.

4. Spacing Recommendation

   What is the recommended plant-to-plant spacing for cabbage to ensure proper head formation?

   1. 25–30 cm
   2. 10–15 cm
   3. 80–100 cm
   4. 45–60 cm

   Explanation: A spacing of 45–60 cm allows cabbages room for head development and good air flow. 10–15 cm is too crowded, leading to small, poor-quality heads. 80–100 cm is unnecessarily wide, wasting space. 25–30 cm is still tight and may restrict head formation.

5. Major Cabbage Pest

   Which pest is known for causing significant leaf damage to cabbage plants by creating holes?

   1. Tomato hornworm
   2. Corn borer
   3. Cabbage looper
   4. Aphid fly

   Explanation: Cabbage loopers are caterpillars that feed on cabbage leaves, creating numerous holes and reducing yield. Aphid flies are generally beneficial predators, not leaf eaters. Corn borers mostly attack corn and related crops, not cabbages. Tomato hornworms are a pest of tomatoes, not typically of cabbage.
