Boosting Cumin Yields Quiz Quiz

Explore key facts about the use of zinc sulphur in cumin cultivation, including its benefits, application methods, and effects. Perfect for understanding zinc sulphur's role in sustainable cumin farming.

1. Role of Zinc Sulphur in Cumin Plants

   What is the primary benefit of applying zinc sulphur to cumin crops during growth?

   1. Improves nutrient uptake and seed yield
   2. Makes cumin seeds larger than normal
   3. Eliminates the need for irrigation
   4. Increases resistance to all pests

   Explanation: Zinc sulphur enhances nutrient availability and uptake, resulting in better growth and seed yield in cumin. While it may contribute to plant health, it does not guarantee resistance to all pests, does not directly increase seed size beyond genetic potential, and cannot replace the necessity of proper irrigation.

2. Symptoms of Zinc Deficiency in Cumin

   Which symptom typically suggests a zinc deficiency in cumin plants?

   1. Chlorosis (yellowing) of young leaves
   2. Wilting of mature leaves only
   3. Purple coloration on stems
   4. Excessive root elongation

   Explanation: Chlorosis in young leaves is a hallmark sign of zinc deficiency, as zinc is crucial for chlorophyll production. Wilting may be associated with water stress, purple stems suggest other deficiencies, and root elongation is not commonly linked with lack of zinc.

3. Timing of Application

   At what growth stage should zinc sulphur typically be applied for optimal cumin yield?

   1. During seed storage
   2. At sowing or early seedling stage
   3. After flowering is complete
   4. Only at harvest

   Explanation: Applying zinc sulphur at sowing or seedling stage helps ensure cumin plants have access to the micronutrient during critical growth periods. Application after flowering or during storage is ineffective, and application at harvest does not benefit plant development.

4. Appropriate Application Methods

   Which is the most common method for applying zinc sulphur to cumin fields?

   1. Soil application as a basal dose
   2. Injecting into irrigation pipes only
   3. Spraying on the harvested seeds
   4. Spreading on foliage after harvest

   Explanation: Soil application as a basal dose allows zinc and sulphur to be available from the early stages of plant growth. Spraying harvested seeds or applying after harvest offers no benefit to plants, and injecting into irrigation is less common for zinc sulphur compared to soil amendments.

5. Interactions With Other Nutrients

   How can excessive phosphorus in soil affect zinc availability to cumin plants?

   1. It increases zinc content in the soil
   2. It can reduce zinc uptake by the plant
   3. It prevents nitrogen absorption
   4. It eliminates the need for zinc supplements

   Explanation: High phosphorus levels can interfere with zinc absorption, leading to deficiencies even when zinc is present. Phosphorus does not increase zinc levels, cannot remove the need for zinc, and does not directly block nitrogen absorption.
