Coriander Planting Pro Quiz Quiz

Sharpen your expertise on coriander sowing with these essential questions, perfect for new and seasoned growers alike. Learn best practices and avoid common mistakes in coriander field preparation and planting.

1. Optimal Sowing Time

   Which season is generally considered best for sowing coriander seeds in most temperate regions to ensure healthy growth?

   1. Mid-summer
   2. Late winter
   3. Spring
   4. Autumn

   Explanation: Spring provides moderate temperatures and adequate moisture, creating favorable conditions for coriander seed germination and growth. Mid-summer often brings excessive heat, late winter can be too cold for germination, and autumn may not allow enough time for the crop to mature before frost.

2. Seed Treatment Importance

   Why is it recommended to soak coriander seeds in water for a few hours before sowing?

   1. To improve germination rate
   2. To change seed color
   3. To prevent insect attack
   4. To remove bitterness

   Explanation: Soaking coriander seeds softens the seed coat and speeds up the absorption of water, which enhances and accelerates their germination. It does not impact bitterness or seed color, and while some soaking may reduce minor pests, it is not primarily for preventing insect attack.

3. Seed Rate Knowledge

   What is the recommended seed rate for direct sowing coriander on one hectare of land?

   1. 5–10 kg
   2. 50–60 kg
   3. 30–35 kg
   4. 80–90 kg

   Explanation: A seed rate of 30–35 kg per hectare is commonly advised for coriander to achieve optimal plant population and yield. Lower rates like 5–10 kg are insufficient for good coverage, while higher rates like 50–60 kg and 80–90 kg can cause overcrowding and wastage.

4. Proper Sowing Depth

   At what depth should coriander seeds typically be sown to ensure good emergence?

   1. 6–7 cm
   2. 2–3 cm
   3. 10 cm
   4. 0.5 cm

   Explanation: Sowing coriander seeds at a depth of 2–3 cm allows for proper soil contact and moisture without hindering seedling emergence. Shallower depths like 0.5 cm risk drying out, while deeper placements such as 6–7 cm or 10 cm may prevent shoots from reaching the surface.

5. Soil Preparation Role

   Which soil preparation step is most important before sowing coriander for improved seedbed conditions?

   1. Leaving large clods
   2. Applying excessive nitrogen
   3. Flooding the field
   4. Leveling and fine tilth

   Explanation: Creating a level and finely-tilled seedbed helps coriander seeds achieve uniform planting depth and even emergence. Excessive nitrogen can stimulate too much leafy growth, flooding is not required for coriander, and large clods impede uniform germination.
