Wheat Wellness Quiz Quiz

Discover key practices and challenges in preventing yellowing of wheat crops, exploring causes, prevention methods, and early detection. This quiz is ideal for anyone interested in improving wheat plant health.

1. Nutrient Deficiency Awareness

   Which essential nutrient is most commonly deficient when young wheat leaves display yellowing starting from the leaf tips?

   1. Zinc
   2. Potassium
   3. Nitrogen
   4. Iron

   Explanation: Nitrogen deficiency usually causes yellowing in wheat, especially starting at the leaf tips. Iron and zinc deficiencies can also cause yellowing, but symptoms often appear differently, such as interveinal chlorosis or in younger leaves. Potassium deficiency typically shows as yellowing alongside marginal burn, not initial tip yellowing.

2. Water Management Practices

   How can over-irrigation contribute to the yellowing of wheat plants in the field?

   1. By attracting wheat moths
   2. By increasing leaf temperature
   3. By waterlogging roots and reducing oxygen
   4. By washing away plant hormones

   Explanation: Over-irrigation can lead to waterlogged soils, reducing oxygen availability and causing yellowing due to root stress. It does not directly wash away plant hormones, attract wheat moths, or increase leaf temperature in a way that causes yellowing.

3. Disease Prevention Strategies

   Which approach helps in preventing yellowing of wheat leaves caused by fungal diseases like yellow rust?

   1. Reducing soil pH below 5
   2. Applying excessive nitrogen
   3. Timely use of resistant wheat varieties
   4. Irrigating daily

   Explanation: Planting resistant wheat varieties helps prevent yellow rust and related yellowing. Reducing soil pH too low or over-irrigation can harm wheat, and excessive nitrogen may lead to lush growth but does not control fungal disease.

4. Role of Pest Management

   A farmer notices patches of yellowing wheat associated with visible insects. What should the initial action be to prevent further yellowing?

   1. Reducing sunlight exposure
   2. Flooding the field
   3. Applying any available chemical
   4. Correctly identifying the pest species

   Explanation: Proper identification of the pest helps choose the most effective control. Random chemical use, field flooding, or reducing sunlight are either ineffective or potentially harmful, leading to more crop stress or wasted resources.

5. Monitoring and Early Detection

   Which technology is increasingly used by farmers to monitor wheat yellowing early and guide targeted prevention?

   1. Manual handpicking of seedlings
   2. Drones with remote sensing
   3. Installing wind turbines
   4. Loudspeakers in fields

   Explanation: Remote sensing via drones helps detect yellowing early for targeted action. Handpicking, loudspeakers, and wind turbines are unrelated or ineffective for monitoring yellowing symptoms at a large scale.
