Study Notes

Planning Crops and Developing Propagation Protocols

Crop planning is essential to deliver high-quality plants on time
Key components include:
- Identifying seed dormancy and applying treatments
- Understanding the three growth phases (establishment, rapid growth, hardening) and their distinct needs
- Developing growing schedules from propagule procurement to final production, including changes in the growing cycle
- Listing resources (space, labor, equipment, supplies) needed during the three growth stages
- Maintaining accurate records (daily logs, plant development records, propagation protocols) for replication
Exact record-keeping is crucial for nursery management, especially for species-specific and site-specific knowledge about seed treatments, germination, and unique crop needs
Benefits of good record-keeping include:
- Invaluable resources for crop planning and scheduling
- Improving nursery productivity and seedling quality over time
- Useful tools for teaching and sharing information about plants
- Preserving and perpetuating propagation information
Planning the schedule, management practices, and facilities for each crop are essential for maximizing seedling growth and quality
Key planning components for plant nurseries:
- Determining available growing space
- Planning crop layout based on the number of plants
- Scheduling seed treatment, plot planting, and pot treatment

Crop Growth Phases

Understanding crop growth phases is crucial for planning
Crops have three phases:
- Establishment: From germination through leaf development (14-21 days to several weeks)
  - Goal: Maximize uniform germination, fill containers effectively, maximize survival, and minimize damping off
  - Needs: Protection from weather, optimal temperatures, irrigation to keep moist but not wet, little to no fertilizer
- Rapid growth: From emergence to a target size (often 10-20 weeks)
  - Goal: Encourage shoot growth, maintain ideal environmental factors, monitor as target size approaches
  - Needs: Optimize temperatures, regular irrigation, proper fertilization
- Hardening (or Conditioning): Transition from rapid growth to dormancy to prepare seedlings for stress (varies widely by species)
  - Goal: Encourage Root and stem diameter growth, acclimate to natural environment, fortify for survival.
  - Needs: Decrease temperatures, reduce photoperiod, decrease moisture stress

Labour and Problems in Scheduling

Labour considerations include pest and disease scouting, monitoring germination, beneficial microorganism introduction, thinning, resowing, and transplanting
Problems with holdover stock:
- Clients not picking up plants on time
- Plant coming out of dormancy, growth from stress, and loss of resistance is possible
Holding plants too long can lead to woody roots, root issues like spiraling, and inability of plants to take in water and crucial nutrients making them vulnerable to wind and damage
