Name two plant science topics commonly tested in FFA CDEs.

• A. Soil chemistry and meteorology
• B. Animal nutrition and poultry housing
• C. Plant propagation and crop science
• D. Greenhouse economics

Answer: (C)

Two plant science topics commonly tested in FFA CDEs are plant propagation and crop science. Plant propagation focuses on how to reproduce plants, using methods like seeds, cuttings, layering, and grafting. Understanding propagation is essential for selecting the right method for different species, maintaining genetic quality, and ensuring reliable production in nurseries or fields. Crop science covers growing crops, including plant physiology, nutrient management, pest and disease control, irrigation, and overall crop production systems. This area translates directly to real-world farming and horticultural practices, which is why it’s a staple in plant-related CDEs. The other options mix in animal science or economics, which are not centered on plant biology topics, making them less aligned with plant science testing.
