Title: Identify common plant nutrient deficiencies and injury symptoms.
Course: Agricultural Production Technology (18301-I) > Section: Using Plant Science in Agricultural Crop Production

Identification should include

- evaluating plant for
  - stunted growth
  - premature bloom
  - chlorosis
  - interveinal chlorosis
  - purplish-red coloring
  - necrosis
  - allelopathic effects
- explaining how the nutrients that are deficient are associated with the symptom
- evaluating plant for
  - insects and wildlife injury
  - mechanical injury (e.g., equipment)
  - chemical injury (pesticides, herbicides)
  - environmental injury (e.g., weather).

Process/Skill Questions:

- What are the symptoms of a nitrogen deficiency? A magnesium deficiency? A phosphorus deficiency?
- Where might you find resources for analysis of plant nutrient deficiency?
- What is an example of an allelopathic effect on a crop?
