Study Notes
Planting Methods
- Direct-seeding plants mature 7-10 days earlier than transplanted plants, such as rice.
Disadvantages of Direct-seeding
- Seeds are exposed to birds, rats, and snails.
- There is greater crop-weed competition due to similarities, especially in grasses.
- Plants tend to lodge more because of less root anchorage.
- More seeds are required due to limitations in germination success.
Indirect Method (Indirect Seeding)
- Plants are grown in starter containers, such as pots, seedboxes, seedbeds, and trays, before being transplanted to a permanent location.
- Allows for greater control over growing conditions, such as protecting soil from pests or germinating in a protected environment like a greenhouse.
Advantages of Indirect Method
- Success rate is higher than direct seeding, resulting in a greater crop yield.
Disadvantages of Indirect Method
- Requires additional preparation and materials, such as seedling trays, which can be expensive.
- Requires careful planning to ensure seedlings are ready for transplantation during the correct growing season.
- Young plants are at risk of transplant shock when transplanted into a new environment.
Specialized Management Practices
- Windbreaks: perennial plants planted at borders to protect the main field.
- Shelter belts: a form of windbreak with varying levels of height.
- Physical control of growth and development: using physical means to manipulate crop growth, such as electromagnetic waves, optical emission, ultrasound, and ionizing radiation.
Specialized Production Systems
- Landscape agriculture: provides aesthetic appeal to an area using plants with compatible or contrasting colors and other elements.
- Ornamental agriculture: crops propagated to provide aesthetic appeal to homes and landscapes.
- Plantation: perennial crops grown on a large scale by an individual or a company.
Steps to Follow in Transplanting Seedlings
- Water seedlings before pulling.
- Pull seedlings carefully without shaking off media from the roots.
- Plant seedlings immediately to prevent roots from drying out.
- Gently press soil around the roots.
- Water seedlings at the soil surface with a gentle stream of water to settle the soil around the roots.
Recommended Seeds for Indirect Seeding
- Small seeds
- Plants that need extra care during their seedling stage, such as tomato, eggplant, mustard, pechay, and pepper.
